Description

Cellular Magnetic Stirrer, 4‑Channel (MS‑C‑S4)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. High‑Throughput, Gentle Stirring for Parallel Cell Culture Expansion
Primary Use: Provides a stepper motor‑driven magnetic stirrer with four independent stirring points, each with a φ105 mm cast‑aluminium work plate, used for the simultaneous, protective, low‑shear mixing of up to four separate cell suspensions, culture media, or reagent solutions in clinical, biopharmaceutical, and research laboratories. Each channel has a maximum stirring capacity of 3 litres (water), a low‑speed range of 5–200 rpm (±1 rpm resolution), and an LED digital display that shows the actual speed in real time. The four positions are spaced 190 mm apart to accommodate standard cell culture vessels without cross‑interference.

How it helps: For the clinical cell culture scientist and bioprocessing specialist, the Cellular Magnetic Stirrer, 4‑Channel (MS‑C‑S4) four independent channels allow parallel processing of multiple cell lines or experimental conditions under identical gentle stirring parameters, greatly increasing throughput while maintaining reproducibility. The low‑speed range and precise stepper motor control (5‑200 rpm, ±1 rpm resolution) ensure delicate cells are stirred without damage, while the high torque even at the lowest speeds guarantees reliable mixing of viscous cell suspensions. The smooth, slow start and stop effectively avoid excessive agitation that could dislodge adherent cells or harm sensitive cultures. By maintaining gentle fluid movement, the stirrer improves gas and nutrient exchange, promoting more efficient cell growth and viability across all four vessels simultaneously. For the patient receiving cell‑based therapies (e.g., stem cells or CAR‑T cells), this parallel, gentle mixing directly supports the scalable, consistent production of high‑quality cell products, reducing the risk of batch‑to‑batch variability and therapy failure.

2. Customisable Work Modes for Diverse Cell Culture Protocols
Primary Use: The Cellular Magnetic Stirrer, 4‑Channel (MS‑C‑S4) features multiple programmable operation modes, including constant speed stirring, cyclic (intermittent) stirring, dual‑speed stirring (both high and low speeds within a single programme), and mixed cycle modes, each of which can be selected and customised through the easy‑to‑use programming interface on each channel. The timer can be set from 0 to 49 minutes 59 seconds.

How it helps: For the cell culture specialist, these programmable modes allow the stirrer to be tailored to the precise needs of a wide range of cell culture applications across all four channels simultaneously or independently. For example, dual‑speed stirring can be used on one channel to alternate between a higher speed to resuspend settled cells and a lower speed to maintain gentle agitation for long‑term cultures, while another channel runs a constant speed mode for standard maintenance. Intermittent (cyclic) stirring can help protect very shear‑sensitive cells on a third channel by providing rest periods between stirring intervals. Programmable settings also support time‑controlled runs (0–49 min 59 sec) to automate workflows across multiple channels. For the patient, more consistent culture conditions and reduced handling steps across parallel cultures help ensure that the final cell product is of the highest possible quality, regardless of batch size.

3. Incubator‑Compatible Design for Optimised Cell Growth Environments
Primary Use: The Cellular Magnetic Stirrer, 4‑Channel (MS‑C‑S4) has a compact, low‑profile design (450×395×90 mm) and a corrosion‑resistant, water‑shedding cast‑aluminium work plate, making it fully compatible for use inside CO₂ incubators, warm rooms, and cold rooms (5–40 °C ambient temperature range, 80 % humidity), where it can provide continuous, gentle stirring directly within the cell culture environment. The IP21‑rated housing and surface non‑accumulation design protect against condensation and minor spills.

How it helps: For the tissue engineering and stem cell biologist, the ability to place the stirrer directly inside the incubator keeps cultures at a uniform temperature and pH while being stirred, eliminating the need to move the culture vessels to a separate benchtop stirrer, which risks temperature fluctuations, spills, and contamination. The corrosion‑resistant, water‑shedding cast‑aluminium work plate prevents water build‑up, while the IP21‑rated housing protects internal electronics against condensation and minor spills. The compact shape (450×395×90 mm) and low weight (5.5 kg) allow it to sit comfortably inside standard incubators without disrupting airflow. For the patient, this integrated, undisturbed culture environment supports better cell growth across all four channels, leading to more consistent and reliable cell therapy products.

4. Remote Monitoring and Data Recording for GLP Compliance
Primary Use: The Cellular Magnetic Stirrer, 4‑Channel (MS‑C‑S4) is equipped with an RS232 data interface that enables remote PC control, real‑time monitoring, and data logging of stirring parameters, such as speed and run time, directly to a laboratory computer or data management system.

How it helps: For the laboratory quality manager and GLP compliance officer, the RS232 interface allows all stirring‑related parameters across all four channels to be automatically recorded, creating a full digital audit trail for each experiment. The instrument’s actual speed is continually displayed on its own LED display, but the RS232 port also communicates this information to a PC for independent verification. This combination of real‑time speed feedback (via the stirrer’s own LED) and remote data recording ensures that any deviation from the set stirring conditions is immediately seen and permanently documented. For the patient, this stringent, auditable quality control means that the final cell therapy product has been manufactured according to reliable and reproducible protocols, directly supporting patient safety.

5. STORAGE & HANDLING ATTRIBUTES

Storage: Store the instrument in a clean, dry, dust‑free environment at room temperature (15–30 °C) when not in use. If the stirrer has been used inside an incubator, allow it to adjust to room temperature before cleaning.
Installation: Place the stirrer on a stable, level, non‑flammable work surface within the recommended operating temperature range (5–40 °C). When installing inside an incubator, ensure adequate clearance for air circulation. Do not place the stirrer on vibrating surfaces, as this may interfere with its smooth operation.
Cleaning: Power off and unplug the stirrer before cleaning. Wipe the cast‑aluminium work plates and outer housing with a soft, slightly damp cloth using a mild laboratory detergent or 70 % ethanol (IPA). The corrosion‑resistant, water‑shedding surfaces can be cleaned even after exposure to culture media or saline solutions. Do not immerse the unit in any liquid. Do not use abrasive cleaners or metal‑scouring pads, as these may damage the work plates.
Pre‑use inspection: Before each use, inspect the power cord and plug for any damage. Ensure all four work plates are clean, dry, and free from any chemical residues. Confirm that each stir bar is in good condition, without chips or cracks. Check that the environmental conditions (e.g., temperature, humidity) are within the instrument’s specified range.
Operation – Standard Stirring: Place up to four culture vessels centrally on each of the four work plates. Add a magnetic stir bar to each vessel, ensuring it is correctly positioned at the bottom. Select the desired stirring mode (constant speed, cyclic, etc.) and set the speed and timer duration via the instrument’s control panel. Use the LED display to confirm the actual speed reading matches the set speed. Always start stirring at a low speed (e.g., 5–20 rpm) to allow each stir bar to couple correctly before gradually increasing to the target speed.
Operation – Parallel Processing: The 190 mm spacing between channels allows four independent culture experiments to be run simultaneously under identical conditions. Each channel can be programmed with independent speed and mode settings, allowing for condition optimisation across multiple channels in parallel.
In‑incubator use: When using the MS‑C‑S4 inside an incubator, ensure the incubator’s internal power outlet is within the specified voltage (100–240 V) and that the power cord does not interfere with the stirrer’s positioning. Position the stirrer so that all four culture vessels are centred over their respective work plates and have adequate clearance for airflow. Avoid placing the unit directly under an incubator’s heating element or forced‑air vent.
RS232 connection: For remote operation and data logging, connect the stirrer to a computer using a standard RS232 cable. The manufacturer’s optional software can be installed to monitor the actual speed and record the operational parameters across all four channels.
Periodic verification: Periodically verify the speed accuracy by comparing the LED‑displayed speed with an independent tachometer reading, particularly after long‑term use or after the stirrer has been moved to a new location. Keep a record of such verifications as part of the instrument’s performance log.

6. LABORATORY & CLINICAL APPLICATIONS

Primary Application: Low‑speed, gentle stirring of cell cultures, culture media, and reagent solutions across four independent channels, primarily for clinical research, biopharmaceutical development, and diagnostic laboratory applications, including the maintenance and expansion of suspension and microcarrier‑adherent cells in parallel.
Clinical Role: An essential instrument for clinical cell culture laboratories, bioprocessing and biomanufacturing facilities, cancer research and drug screening units, and academic research institutions.

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Magnetic Field Interference — Medical Devices: The stirrer contains strong permanent magnets in each of the four channels. People with implanted medical devices (e.g., pacemakers, implantable cardioverter‑defibrillators, neurostimulators) should keep a safe distance of at least 30 cm from the operating stirrer. The combined magnetic field from four active channels may be stronger than a single‑channel device. Do not place the instrument near credit cards, hard drives, computer monitors, or other magnetic‑sensitive equipment.
Vessel and Stir Bar Selection: Use only flat‑bottomed vessels (cell culture flasks, beakers, spinner flasks) that sit flush on the cast‑aluminium work plates. Ensure each magnetic stir bar is in good condition without chips, cracks, or deformities and is properly centered in each vessel before starting. Do not exceed the maximum stir bar length of 80 mm per channel.
Start Slowly (Smooth Start): For each channel independently, always start stirring at the lowest speed (5–20 rpm) and gradually increase to the desired level. A sudden high‑speed start may cause the stir bar to decouple, spin erratically, or strike the vessel wall, leading to splashing, spillage, or vessel breakage. For very shear‑sensitive cells, keep speeds below 50 rpm.
Electrical Safety: Do not operate the instrument with wet hands. Ensure the mains power cable does not come into contact with liquids or sharp edges that could damage the insulation. Use only the supplied grounded power cord and ensure the outlet provides proper grounding. Disconnect the power cord before cleaning, servicing, or moving the unit. Do not operate if the power cord is damaged. The IP21 rating offers basic protection against vertically falling water drops, but does not protect against immersion or significant liquid spills.
Incubator Installation Safety: When installing inside an incubator, ensure the unit is placed on a stable, level surface and that the power cord does not interfere with incubator doors, shelves, or airflow. Verify that the incubator’s internal power outlet is properly grounded and within the specified voltage rating. Avoid placing the stirrer directly above heating elements or in the path of forced air vents, as this may cause overheating of the stirrer’s electronics.
Channel Independence and Vessel Spacing: The four channels operate independently. Ensure that vessels placed on adjacent channels do not touch or interfere with each other. The pre‑determined channel spacing allows standard vessels up to 3 L capacity, but oversized vessels may crowd adjacent positions. Always allow sufficient clearance between vessels to prevent magnetic interference between channels and to avoid accidental contact.
Chemical Compatibility: The cast‑aluminium work plates are resistant to many common laboratory chemicals used in cell culture, but prolonged exposure to strong acids, strong alkalis, or aggressive organic solvents may damage the surface. Clean spills promptly. Refer to the Safety Data Sheet (SDS) for specific chemicals.
Spill Management: If a liquid spill occurs on any work plate during operation, turn off the affected channel(s) immediately. Unplug the unit, wipe the spill clean with a soft, damp cloth, and allow the surface to dry thoroughly before resuming use. Do not let liquids seep under the work plates or into the housing. The IP21 rating does not protect against pooling liquids or immersion.
Operating Environment — Clean, Stable Benchtop: Use the MS‑C‑S4 indoors only, on a stable, level, non‑flammable laboratory benchtop or inside an incubator. Do not use in explosive atmospheres or in the presence of flammable gases or vapours. The permissible ambient temperature range is 5–40 °C with relative humidity not exceeding 80 %. Allow adequate clearance for ventilation; do not cover the instrument during operation.
Cleaning and Maintenance: Unplug the unit before cleaning. Allow any warm plates to cool to room temperature before wiping. Use only a soft, damp cloth with mild detergent or 70 % isopropyl alcohol. Do not use abrasive cleaners, metal scouring pads, or sharp objects that may scratch the cast‑aluminium surface. Do not immerse the unit or allow liquid to enter the housing. The stepper motor requires no routine maintenance, but periodically inspect the power cord for signs of wear or damage.
Pre‑Use Inspection: Before each use, inspect the power cord and plug for any damage. Ensure all four work plates are clean, dry, and free of chemical residues. Verify that all magnetic stir bars are in good condition without chips or cracks and are appropriate for the vessel size (maximum length 80 mm). Check that the environmental conditions are within the instrument’s specified range.
Training Requirement — Qualified Users Only: Only trained laboratory personnel with appropriate technical background in magnetic stirrer operation and cell culture handling should operate the MS‑C‑S4 for clinical diagnostic or research applications. Users must read and understand the operator’s manual before first use. Laboratory managers should ensure all operators are aware of the independent channel control features, the proper procedure for starting and stopping stir bars across four channels, and the specific safety considerations for stirring cell cultures.

2. FIRST AID MEASURES

Sample Splash to Eyes: If a biological or chemical sample splashes into the eyes during stirring, flush immediately with water for 15 minutes and seek medical attention.
Skin Contact with Chemical Sample: Wash contaminated skin with soap and water thoroughly for at least 5 minutes. If irritation or signs of infection develop, seek medical evaluation.
Sharps Injury (Broken Glassware): If a broken vessel punctures the skin, allow the wound to bleed freely, wash with soap and water for 15 minutes, apply antiseptic and a sterile bandage. If the vessel contained patient biological material, follow the facility’s exposure management protocol for bloodborne pathogens.
Inhalation of Chemical Vapors: If vapors from volatile reagents are inhaled during sample preparation, move to fresh air immediately; seek medical attention if symptoms persist.
Electrical Shock: If an electrical shock incident occurs, disconnect power at the circuit breaker before attempting to assist the victim. Do not touch the victim until power is disconnected. Call emergency medical services immediately.

3. FIRE FIGHTING MEASURES

Flammability: The plastic components of the stirrer housing and the power cord are combustible. Do not operate near flammable solvents, gases, or volatile materials. The primary fire hazard is the flammable liquids being stirred.
Extinguishing Media: Use carbon dioxide (CO₂) or a dry chemical extinguisher for fires involving electrical equipment. Do not use water on electrical fires.
Fire Response: In case of fire, disconnect the stirrer from its power source if safe to do so, evacuate the area, and follow the laboratory’s fire safety protocols.
Special Protective Equipment for Firefighters: Firefighters should wear self‑contained breathing apparatus (SCBA) and full structural firefighting gear when fighting fires in laboratory settings.

3. FIRE FIGHTING MEASURES

Flammability: The plastic components of the stirrer housing and the power cord are combustible. Do not operate near flammable solvents, gases, or volatile materials. The primary fire hazard is the flammable liquids being stirred.

Extinguishing Media: Use carbon dioxide (CO₂) or a dry chemical extinguisher for fires involving electrical equipment. Do not use water on electrical fires.

Fire Response: In case of fire, disconnect the stirrer from its power source if safe to do so, evacuate the area, and follow the laboratory’s fire safety protocols.

Special Protective Equipment for Firefighters: Firefighters should wear self‑contained breathing apparatus (SCBA) and full structural firefighting gear when fighting fires in laboratory settings.
