It features a speed range of 15 to 1500 rpm, an automatic reverse rotation function for superior mixing, and a maximum stirring capacity of 0.8 liters.

How it helps: For the clinical laboratory scientist and analytical chemist, the FlatSpin’s revolutionary motorless technology ensures ultra-silent and vibration-free operation, which is critical for sensitive analytical procedures on crowded benchtops. With a height of only 15 mm, it fits easily under a bottle-top burette during titrations and in tight spaces like culture hoods and glove boxes, freeing up valuable workspace. For the patient, the consistent and reproducible mixing of reagents and samples in quality control and analytical labs supports accurate diagnostic test results and pharmaceutical product safety.

2. General Chemical and Reagent Preparation for Sample Analysis
Primary Use: Used for the efficient and homogeneous mixing of a wide range of liquids, including buffers, standard solutions, and clinical reagents, before analysis. Despite its compact size, it is engineered for excellent mixing efficiency for most standard laboratory solutions.

How it helps: For the medical technologist, the FlatSpin’s simple push-button controls, a bright digital display, and an automatic reverse rotation mode that changes direction every 15 seconds provide powerful and even stirring for complex or colloidal solutions. Its PET work plate offers excellent chemical resistance to common laboratory acids and solvents, ensuring long-term durability. For the patient, this reliable preparation of chemical and biological reagents is the foundation of accurate diagnostic testing, leading to better clinical outcomes.

3. Sample Preparation in Point-of-Care and Decentralized Testing
Primary Use: Serves as an ideal mixing tool for small-volume sample preparation in point-of-care testing (POCT) settings, mobile laboratories, and space-constrained clinical stations, ensuring homogeneity for rapid diagnostic tests (RDTs) and other on-site assays.

How it helps: For the laboratory technician in a satellite or outreach clinic, the FlatSpin’s ultra-compact dimensions (175 × 120 × 15 mm) and light weight (0.3 kg) allow it to be easily stored and transported. Its quiet operation and IP65-rated splash resistance make it suitable for use in busy, humid environments or on open workbenches without disturbing nearby procedures. For the patient, proper sample preparation at the point of care leads to reliable, immediate results, enabling faster clinical decisions and treatment initiation.

SECONDARY & SUPPORTIVE USES

1. Titration procedures (bottle-top burette): The ultra-flat 15 mm height allows the stirrer to be placed directly under a bottle-top burette, providing unobstructed, continuous stirring during analytical chemistry titrations without needing to transfer the beaker, making it the perfect magnetic stirrer for this application.

2. Automatic reverse rotation for enhanced mixing: The built-in auto-reverse mode automatically changes the direction of rotation every 15 seconds, which improves mixing efficiency for complex or colloidal solutions, prevents the formation of a central vortex, and helps keep solids evenly suspended.

3. Space-constrained workstations (fume hoods, glove boxes): With a footprint similar to a postcard and a height of only 15 mm, the FlatSpin is ideal for use in crowded fume hoods, biological safety cabinets, and glove boxes where vertical space is extremely limited and a traditional stirrer would not fit.

4. Educational and teaching laboratories: An ideal tool for practical work sessions and educational protocols, its simplicity, safety (IP65), and durable PET top make it perfect for teaching basic principles of solution mixing, dissolution testing, and homogenization in chemistry and biology labs.

5. Quality control (QC) sample preparation: In quality control laboratories, the FlatSpin ensures standard preparations and analytical protocols are performed with reliable and homogeneous stirring, improving the reproducibility of results for routine product testing.

6. Mobile and field laboratory testing: Its low power consumption (5W) and universal power supply make it suitable for mobile labs and field testing units. Some distributors also offer 12V DC options for portable use powered by a vehicle, enabling on-site environmental or food safety testing.

7. Dissolution testing and small-volume homogenization: The FlatSpin can be used for quick dissolution testing of tablets or powders in small volumes (up to 0.8L) and for light homogenization of suspensions in research and small-scale industrial settings.

Clinical Role: A specialized instrument for clinical diagnostic labs, analytical chemistry departments, pharmaceutical quality control (QC) labs, educational institutions, and research facilities. It is critical for titration procedures, mixing reagents for sensitive assays, and preparing solutions in space-constrained or quiet laboratory environments.

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Magnetic Device Safety: The FlatSpin contains strong permanent magnets. People with implanted medical devices (e.g., pacemakers, defibrillators, infusion pumps) should keep a safe distance (at least 30 cm). Keep the stirrer away from magnetic-sensitive media (hard drives, credit cards, monitors, CRTs).
Chemical Compatibility: While the PET work plate is chemically resistant, prolonged exposure to some concentrated acids or aggressive organic solvents could cause damage. Clean up spills promptly. Always refer to the SDS for the specific chemicals used and verify compatibility with PET plastic.
Vessel and Stir Bar Selection: For maximum efficiency and safety, use beakers or vessels with perfectly flat bottoms and low fluting. Recommended stir bar size is 20 × 8 mm or a maximum of 40 mm in length. Ensure the stir bar is properly centered before starting.
Start Slowly: Always start with the speed at its lowest setting and allow the stir bar to settle into rotation before gradually increasing to the desired speed. This prevents the stir bar from decoupling, which can cause splashing.
Cleaning: Disconnect the power supply before cleaning. Do not immerse or allow liquids to enter the instrument housing. The IP rating offers protection against splashes, not full immersion.
Training Requirement: Only trained laboratory personnel should operate the DLAB FlatSpin Ultra-flat Compact Magnetic Stirrer for clinical or diagnostic applications.

2. FIRST AID MEASURES

Sample Splash to Eyes: If a biological or chemical sample splashes into the eyes, flush immediately with water for 15 minutes and seek medical attention.
Skin Contact: Wash contaminated skin with soap and water thoroughly. If irritation or signs of infection develop, seek medical evaluation.
Chemical Exposure: If a hazardous chemical is spilled on the skin or clothing, refer to the specific Safety Data Sheet (SDS) for that chemical for detailed first-aid instructions.
Inhalation: If chemical 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. Seek emergency medical attention.

3. FIRE FIGHTING MEASURES

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