Detailed Product Description
The StemAids Hei-Mix S Magnetic Stirrer HEIDOLPH is designed for laboratories that need dependable magnetic stirring without unnecessary complexity. Its compact body allows easy placement on laboratory benches, inside teaching labs and near analytical workstations.
With a stirring capacity of up to 5 litres and a maximum speed of 2,200 rpm, this stirrer supports both gentle mixing and faster agitation depending on the sample requirement. It is suitable for preparing solutions, mixing reagents, supporting titration work and maintaining uniform liquid movement during routine laboratory procedures.
The white PVDF plate is a practical feature for titrations and colour-sensitive reactions because it helps users observe visual changes more clearly. This makes the product useful for chemistry laboratories, biology laboratories, microbiology labs and teaching demonstrations.
The Hei-Mix S does not include a heating plate. This makes it suitable for applications where controlled stirring is required without heat exposure. For heat-sensitive biological or chemical samples, a non-heating magnetic stirrer can help reduce the risk of unwanted thermal effects.
Applications
- Chemical solution mixing
- Titration procedures
- Biochemical sample preparation
- Microbiology laboratory work
- Small-scale fermentation support
- Educational chemistry practicals
- Research and development laboratories
- Quality control laboratory testing
- Routine reagent preparation
- Non-heated sample stirring applications
How to Use Hei-Mix S Magnetic Stirrer
- Place the stirrer correctly: Keep the magnetic stirrer on a clean, dry, flat and stable laboratory bench.
- Select a suitable vessel: Use a compatible glass beaker, flask or laboratory container suitable for magnetic stirring.
- Add the magnetic stir bar: Place a clean magnetic stir bar inside the liquid sample.
- Position the vessel: Keep the vessel in the centre of the white PVDF top plate.
- Switch on the unit: Connect the stirrer to the correct power supply and switch it on.
- Adjust the speed: Slowly increase the stirring speed using the control knob until the required vortex or mixing action is achieved.
- Monitor the process: Observe the liquid movement and avoid excessive speed that may cause splashing or unstable stirring.
- Stop after use: Turn the speed control back to zero before removing the vessel.
- Clean the surface: Wipe the top plate with a soft cloth after use. Do not allow liquid to enter the housing.
Safety Instructions
- Do not use the Hei-Mix S as a heating device.
- Do not exceed the recommended stirring capacity.
- Always use a suitable magnetic stir bar and compatible vessel.
- Increase speed gradually to avoid splashing.
- Do not operate the instrument with damaged cables or plugs.
- Keep liquids away from electrical parts and control areas.
- Use appropriate laboratory PPE such as gloves, goggles and lab coat.
- Switch off and unplug the unit before cleaning.
