LCD Digital Heating Magnetic Stirring Bath (MS‑H220‑V5)
PRIMARY CLINICAL & DIAGNOSTIC USES
1. Dual‑Use Water and Oil Bath for 5‑Litre Clinical and Research Applications
Primary Use: Provides a fully programmable LCD digital heating magnetic stirring bath with a high borosilicate glass liner and stainless steel base (Ø240×135 mm bath size, 5‑litre water capacity), used for the precise and homogeneous heating and simultaneous stirring of clinical reagents, biological samples, and diagnostic solutions in clinical chemistry, pharmaceutical formulation, analytical chemistry, and research laboratories, with a temperature range from room temperature up to 220 °C (±1 °C accuracy) in 1 °C increments, and a speed range of 100 to 1500 rpm (±10 rpm) for effective mixing.
How it helps: For the clinical chemistry technologist and pharmaceutical research scientist handling larger 5‑litre volumes, the MS‑H220‑V5’s water‑and‑oil dual‑use capability provides the flexibility to work with both media types. The larger bath dimensions (Ø240 mm) can accommodate wider or taller vessels up to a 5‑litre flask, making the V5 ideal for laboratories that routinely process larger sample volumes or need to submerge bulkier glassware. The transparent glass liner allows visual monitoring of reaction product changes without disturbing the experiment. The built‑in stirring function – a unique secondary stirring effect – ensures that the bath fluid is constantly agitated, while simultaneously driving the magnetic stir bar inside the reaction vessel. This dual‑stirring action eliminates thermal gradients and maintains a uniform temperature environment around and within the sample vessel. For the patient, the larger 5‑litre capacity permits the simultaneous processing of more samples or the use of larger reaction flasks, improving laboratory efficiency and throughput without sacrificing the temperature reproducibility required for reliable diagnostic test outcomes.
2. Large‑Volume Sample Digestion for Trace Element and Environmental Analysis
Primary Use: Enables the controlled heating and simultaneous magnetic stirring of bulk biological materials (blood, urine, tissue samples) or environmental specimens (soil extracts, water samples, sediment suspensions) at temperatures up to 220 °C, using either water bath (up to 100 °C) or oil bath (100–220 °C) modes, prior to trace element analysis by atomic absorption spectroscopy or inductively coupled plasma mass spectrometry.
How it helps: For the analytical chemist performing sample digestion for heavy‑metal testing, the MS‑H220‑V5’s 5‑litre capacity allows the preparation of up to 250 % more digested material per batch compared to the 3‑litre V3 model, significantly reducing preparation time for high‑throughput workflows. The secondary stirring (bath fluid agitation plus flask‑internal stirring) ensures complete oxidation of organic matrices without hot spots, even when working with larger sample volumes in wide‑necked flasks. The optional PT1000 external temperature sensor (±0.2 °C accuracy) can be connected for direct, closed‑loop control of the liquid sample temperature, providing the precision required for regulatory‑grade analytical workflows. For the patient undergoing heavy‑metal screening (blood lead, urine cadmium) as part of occupational health monitoring or assessment of suspected poisoning, the use of larger, uniform, accurately heated batches supports more efficient processing of incoming samples and contributes to accurate, timely results.
3. Reaction Monitoring and Pharmaceutical Quality Control for 5‑Litre Workflows
Primary Use: The transparent bath and wide range of accessories make this 5‑litre‑capacity unit suitable for pharmaceutical quality control testing involving larger reaction volumes, material reaction monitoring, and extended‑duration studies where observation and data logging are required.
How it helps: For the pharmaceutical quality control analyst, the LCD digital control, programmable timer with buzzer (1 minute to 99 hours 59 minutes), and a safety lock feature allow for precise, unattended operation. The larger bath dimensions accommodate wider flasks and taller beakers – up to a 5‑litre flask, according to manufacturer specifications. When the countdown concludes, the unit stops heating (to prevent sample damage) but continues stirring to maintain homogeneity. This is critical for long‑duration dissolution studies, extended reaction monitoring, and accelerated stability testing on larger batches of drug substance or product. The integrated PT1000 temperature sensor port (sensor optional) ensures that the thermal process is documented to Good Laboratory Practice standards. For the patient, the capacity to test larger batches under tightly controlled conditions helps ensure that pharmaceutical products remain safe and effective throughout their marketed shelf life.
4. Low‑Noise, Maintenance‑Free Incubation and Stirring for Clinical Microbiology
Primary Use: Utilised in clinical microbiology laboratories for the gentle yet uniform heating of bulk culture media and for mixing large‑scale microorganism suspensions in broth, without the mechanical friction or sparking associated with conventional motors.
How it helps: For the clinical microbiology technologist working with larger media volumes, the MS‑H220‑V5’s spark‑free, maintenance‑free brushless DC motor operates at very low noise levels and generates no electromagnetic sparking, making it safe for use in environments with potential flammable vapours. The IP21‑rated housing and residual heat warning function (flashing “HOT” on the display when the plate temperature exceeds 50 °C, continuing even after the unit is turned off) enhance user safety in busy lab environments. The transparent bath allows real‑time visual monitoring of culture growth and reactions without opening the vessel. For the patient, a 5‑litre bath capacity can improve the efficiency of high‑volume clinical microbiology testing, helping to reduce assay turnaround times and enabling faster identification of pathogens from clinical specimens.

KEY PRODUCT FEATURES
1. SAFETY PRECAUTIONS
-
Burn Hazard — High Plate and Mantle Temperature: The heating bath can reach 220 °C and the hot glass liner remains dangerously hot for an extended period after the power is turned off. Do not touch the hot glass liner, stainless steel base, or metal housing for at least 30‑60 minutes after use, or until the residual heat “HOT” indicator stops flashing. Use appropriate heat‑resistant gloves or tools when handling vessels or removing them from the bath. Severe burns can occur upon contact.
-
Residual Heat Warning — Continues Even When Off: The “HOT” safety indicator activates when the bath temperature exceeds 50 °C and continues flashing on the display even after the unit is turned off (if still connected to mains). This critical safety feature alerts users to the dangerously hot surface until the plate is safe to touch (temperature drops below 50 °C). Always verify that the “HOT” indicator has stopped flashing before touching the bath or removing vessels.
-
Fire Hazard — Avoid Flammable Materials and Dry‑Burn Condition: Do not operate the instrument near flammable materials, volatile solvents, combustible gases, or paper products. Keep the work area clear of flammable substances. The heating temperature must be set at least 50 °C lower than the ignition point of the chemicals being used. Do not operate the bath without sufficient water or oil in the glass liner – dry‑burning protection will activate and stop heating, but this should not replace operator vigilance. Do not leave the instrument unattended while operating at high temperatures without appropriate safety protocols.
-
Glass Breakage Hazard — Thermal Shock: The high borosilicate glass liner is resistant to thermal shock, but sudden temperature changes (eg, adding cold liquid to a hot bath) can still cause the glass to crack or shatter. Never add cold liquid to the glass bath to cool it – allow natural convection cooling. Always allow the bath to heat up gradually from a low starting temperature. Inspect the glass liner for cracks before each use.
-
Over‑Temperature Protection — Dual Independent Safety Circuits: The instrument has dual independent safety circuits that continuously monitor the device. If the bath exceeds 350 °C or a built‑in sensor malfunctions, the machine stops heating, displays an error message and may sound an audible alarm. If the first safety circuit fails and a short‑circuit is detected, the second safety circuit cuts off the power supply to ensure operator safety.
-
Vessel Selection — Proper Vessel Fit: Use only heat‑resistant glassware (borosilicate glass such as Pyrex or Kimax) designed for high‑temperature water/oil bath applications. Ensure the vessel is stable, fully immersed to the appropriate depth, and does not touch the bottom or sides of the glass bath. The maximum recommended vessel size for the V5 is 5 liters.
-
Magnetic Stir Bar and Coupling: Use only magnetic stir bars in good condition without chips, cracks or deformities. For the MS‑H220‑V5 with 5 L capacity, use stir bars up to 40 mm in length and made of PTFE‑coated materials suitable for the bath medium (water or oil). Start stirring at a low speed (100‑200 rpm) to allow the stir bar to couple correctly before gradually increasing to the target speed. Always center the vessel over the magnetic drive before starting.
-
Electrical Safety — Proper Grounding: 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 protection against vertically falling water drops, but does not protect against immersion or significant liquid spills.
-
Bath Medium Selection: Use only appropriate media: water for water bath applications (up to 100 °C) or heat‑transfer oil for oil bath applications (100‑220 °C). Do not use volatile oils or solvents that could create flammable vapors at elevated temperatures. Always follow the bath medium manufacturer's recommendations for maximum operating temperature and compatibility.
-
External PT1000 Sensor Safety — Secure Placement: When using the PT1000 external temperature sensor (optional accessory, sold separately), insert the sensor probe into the sample vessel and secure it with a suitable stand and clamp. Do not allow the sensor cable to contact the hot glass bath, as this may melt the wire insulation and cause sensor failure, electrical hazard or burns. If any abnormal situation is detected (e.g., sensor failure or disconnection, indicated by an error code on the display), the heating mode will automatically shut down as a safety precaution. Always inspect the sensor cable for damage before use.
-
Cleaning and Maintenance — Safe Cleaning Protocols: Unplug the unit and allow the bath and glass liner to cool completely before cleaning. Wipe the high borosilicate glass liner, stainless steel base, and protective outer housing with a soft, damp cloth using a mild laboratory detergent or 70 % isopropyl alcohol. Do not immerse the unit in liquid or allow liquid to penetrate the housing. The brushless DC motor requires no routine maintenance, but periodically inspect the power cord for signs of wear or damage. Never use abrasive cleaners, metal scouring pads, or sharp objects that could scratch the glass liner.
-
Training Requirement — Qualified Users Only: Only trained laboratory personnel with appropriate technical background in hotplate stirrer and heating bath operation should operate this instrument 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 potential for glass breakage, the proper use of stirring bars, and the specific safety considerations for heating hazardous materials with either water or oil baths.

Urinalysis Strips are Class II medical devices (FDA-cleared) consisting of plastic strips with multiple reagent-impregnated pads for simultaneous semi-quantitative detection of urine analytes including leukocytes, nitrites, urobilinogen, protein, pH, blood, specific gravity, ketones, bilirubin, and glucose. Results read by visual comparison to color chart at specified times (30-120 seconds). Primary clinical applications include routine health screening, urinary tract infection diagnosis, diabetes screening and monitoring, kidney disease assessment (proteinuria), hematuria detection, liver function evaluation, and pregnancy monitoring (preeclampsia screening). Critical safety precautions include proper specimen collection (fresh urine), storage at 15-30°C in original container with desiccant, protection from humidity, reading at exact specified times, awareness of interfering substances (ascorbic acid), and confirmation of abnormal results with quantitative tests. Essential screening tool in primary care, emergency medicine, nephrology, urology, and obstetrics.
