Product Description

85-2 Digital Magnetic Stirrer with Heating & Temperature Control

Bio Shop™ presents the 85-2 Digital Magnetic Stirrer, a practical laboratory mixing machine designed for controlled stirring and heating of compatible liquid formulations.

This unit combines a magnetic stirring platform, digital temperature display, adjustable stirring speed, temperature probe, and heated stainless-steel plate in one compact benchtop machine. It is suitable for laboratory work, cosmetic formulation, skincare development, perfume-related mixing, educational use, and other controlled liquid-mixing applications.

The front-mounted digital controller allows the operator to monitor temperature, while the Speed Adjust knob provides convenient control over stirring intensity. The machine also includes a support rod and adjustable clamp for positioning the temperature probe inside the beaker during use.

Magnetic Stirring with Beaker

A magnetic stir bar is placed inside the beaker, and the beaker is positioned on the stainless-steel plate. When the stirrer is switched on, the magnetic field rotates the stir bar inside the liquid, helping create continuous and even mixing without the need for manual stirring.

This makes the machine useful for combining compatible water-based or other liquid formulations where consistent agitation is required.

Heating & Temperature Monitoring

The 85-2 magnetic stirrer is designed with a heated top plate and digital temperature controller. The adjustable probe can be positioned directly inside the liquid to monitor the working temperature during mixing.

This feature is particularly useful when preparing formulations where controlled warming and continuous stirring are required at the same time.

Adjustable Speed Control

The front Speed Adjust knob allows the user to increase or decrease the stirring speed according to the formulation and batch size.

Lower speeds may be used for gentle mixing, while higher settings can create stronger circulation or a visible vortex in suitable liquids.

Useful for Cosmetic Formulation

For DIY cosmetic makers and small formulation businesses, a magnetic stirrer can help improve consistency when preparing compatible liquid products and laboratory test batches.

It can be used during development work for:

• Cosmetic solutions
• Toners
• Liquid skincare formulations
• Water-based mixtures
• Laboratory test batches
• Ingredient dissolution
• Small formulation trials
• Educational laboratory work

7. How to Use

1. Place the magnetic stirrer on a stable, dry work surface.
2. Put a suitable magnetic stir bar inside the beaker.
3. Place the beaker in the center of the stainless-steel plate.
4. Position the temperature probe inside the liquid if temperature monitoring is required.
5. Switch on the unit.
6. Start at a low stirring speed and increase gradually.
7. Adjust temperature according to the requirements of the formulation.
8. Monitor the liquid during operation.
9. After use, reduce speed, switch off the machine, and allow the hot plate to cool before handling.

8. Safety & Usage Notes

• Use only compatible heat-resistant laboratory containers.
• Do not touch the heating plate while hot.
• Start stirring at low speed to reduce splashing.
• Keep electrical components and connections dry.
• Do not operate the unit unattended during heated applications.
• Ensure the probe and clamp are securely positioned before operation.
• Actual operating settings should be selected according to the formulation being prepared.
