Magnetic Stirrer MS-S LAB

The StemAids Magnetic Stirrer MS-S LAB is a compact, durable and efficient laboratory magnetic stirrer designed for smooth liquid mixing, reagent preparation, solution stirring and routine laboratory applications. It is suitable for chemistry laboratories, biology laboratories, school labs, college labs, research centres, quality control laboratories and institutional science facilities.

This magnetic stirrer is suitable for laboratories that require reliable stirring performance without integrated heating. With a stirring capacity of up to 20 litres and a speed range of 0 to 1500 rpm, the MS-S LAB supports gentle to moderate stirring of aqueous solutions, buffers, reagents and routine laboratory liquids.

Important Heating Note: The MS-S LAB / DLAB MS-S model is a non-heating magnetic stirrer. It does not include a hotplate, heating element, heating temperature control or integrated heating function. If heating is required, users should select a dedicated hotplate magnetic stirrer model.

Product Specifications

Detailed Product Description

The StemAids Magnetic Stirrer MS-S LAB is designed for laboratories that need dependable liquid stirring without heating. It uses magnetic coupling to rotate a stir bar inside a liquid sample, producing uniform mixing without direct mechanical contact with the liquid.

The instrument is suitable for preparing solutions, dissolving reagents, mixing buffers, stirring laboratory chemicals and supporting educational experiments. Its 20 L maximum stirring quantity makes it suitable for both small-volume and medium-volume laboratory applications.

The stainless-steel plate with ceramic coating provides improved resistance against chemical exposure and helps support stable vessel placement during stirring. The brushless DC motor supports quiet, efficient and low-maintenance performance, making the stirrer suitable for routine use in academic and professional laboratories.

Since the MS-S LAB is a non-heating magnetic stirrer, it is especially useful for heat-sensitive samples where controlled mixing is required without temperature increase. For laboratories that need simultaneous heating and stirring, a hotplate magnetic stirrer should be selected separately.

Applications

• Chemical solution preparation
• Reagent and buffer mixing
• Biology laboratory sample stirring
• Chemistry practical demonstrations
• Educational science laboratory work
• Quality control laboratory testing
• Research and development sample preparation
• Mixing of low-viscosity liquids
• Routine laboratory liquid handling
• Non-heated stirring of heat-sensitive samples

How to Use Magnetic Stirrer MS-S LAB

1. Place the stirrer properly: Keep the unit on a clean, dry, flat and stable laboratory bench.
2. Check the power supply: Ensure that the available voltage matches the instrument rating before connecting the power cable.
3. Select a suitable vessel: Use a compatible beaker, flask or container that can sit safely on the work plate.
4. Add the stir bar: Place a clean magnetic stir bar inside the liquid sample.
5. Centre the vessel: Keep the vessel in the centre of the Ø135 mm work plate for stable stirring.
6. Start at low speed: Switch on the stirrer and begin at a low speed to avoid splashing or stir bar movement.
7. Increase speed gradually: Adjust the speed control slowly up to the required mixing level.
8. Monitor operation: Observe the vortex and sample movement to ensure stable mixing.
9. Stop after use: Turn the speed control back to zero before removing the vessel.
10. Clean the plate: Wipe the ceramic-coated surface with a soft cloth after use. Do not allow liquid to enter the instrument body.

Safety Instructions

• Do not use this model for heating, as it has no integrated hotplate.
• Do not exceed the recommended stirring capacity.
• Use a suitable magnetic stir bar according to vessel size and liquid volume.
• Increase stirring speed gradually to prevent splashing.
• Do not operate the unit with damaged wires or loose electrical connections.
• Keep liquids away from the motor housing and electrical parts.
• Use appropriate laboratory PPE such as gloves, safety goggles and lab coat.
• Do not use with highly viscous samples beyond the stirrer capacity.
• Switch off and unplug the instrument before cleaning.
• Use only in a dry indoor laboratory environment.
