Hot Plate Stirrer

Designed for laboratory heating and stirring applications, Hawach hot plate stirrers deliver stable temperature control and reliable mixing performance for pharmaceutical QC, chemical synthesis, and routine laboratory workflows.

A hot plate stirrer (also known as a heated magnetic stirrer or laboratory hot plate stirrer) is one of the most commonly used benchtop laboratory instruments for simultaneous heating and magnetic stirring of liquid samples. Available in 1, 2, 4, and 6 stirring positions, with heating wire or heating plate options, digital or analog control, and brushless DC motor models for continuous duty. All models provide precise temperature control up to 100°C with ±1°C accuracy.

Hot Plate Stirrer vs Magnetic Stirrer vs Hotplate – Which One Do You Need?

Conclusion: Choose a hot plate stirrer when your workflow requires both heating and mixing. For stirring only, use a standard magnetic stirrer. For heating only, use a laboratory hotplate.

What Is a Hot Plate Stirrer?

A hot plate stirrer (heated magnetic stirrer, laboratory hotplate stirrer) is an integrated laboratory instrument that combines a temperature-controlled hot plate with a magnetic stirring mechanism. All Hawach models include heating – either via economical heating wire (18031001, 18031004, 18031007) or more uniform heating plate (all other models).

These instruments are widely used in pharmaceutical laboratories, chemical manufacturing, biotechnology research, and academic institutions where controlled heating and reproducible mixing are required.

Hawach hot plate stirrers are available in 1, 2, 4, and 6 stirring positions, with heating power up to 200 W per position, temperature range RT +5°C to 100°C (±1°C accuracy), and speed range 200-2400 rpm. Select models feature brushless DC motors for continuous operation, digital displays for real-time speed/temperature monitoring, and extended timers up to 9999 min.

How to Select the Right Hot Plate Stirrer for Your Lab – 4 Key Factors

• Heating element type: Heating wire models (18031001, 18031004, 18031007) are cost-effective for general use. Heating plate models provide more uniform temperature distribution and faster heat-up – ideal for precise temperature control.
• Sample volume per position: Up to 1,000 mL per position. For larger volumes, consider overhead stirrers.
• Number of samples per day: 1-10 samples/day → single-position; 10-50 samples/day → 2 or 4 positions; 50+ samples/day → 6 positions.
• Continuous operation needed? Choose brushless DC motor models (18031003, 18031006, 18031009, 18031012) for 24/7 unattended mixing.

Key Features of Hawach Hot Plate Stirrers

• All models include heating– Choose between economical heating wire (18031001, 18031004, 18031007) or precision heating plate (all other models).
• Wide temperature range (RT +5°C to 100°C, ±1°C accuracy)– Suitable for most laboratory heating applications.
• Adjustable speed (200-2400 rpm)– Stepless regulation from gentle mixing to vigorous agitation.
• Brushless DC motor models– Maintenance-free, quiet operation, continuous duty (18031003, 18031006, 18031009, 18031012).
• Asynchronous stirring on multi-position models– Each position operates independently.
• Digital display models– Real-time speed/temperature readout, programmable timer (0-120 min or 0-9999 min).
• Up to 1,000 mL stirring capacity per position– Compatible with standard glassware.
• Stainless steel work plate– Durable, corrosion-
• CE marked, ISO 9001 certified.

Asynchronous Independent Control – A Key Advantage on Multi-Position Models

On 2-, 4-, and 6-position Hawach hot plate stirrers, each stirring position can be set to a different speed and temperature independently. This allows parallel experiments under different conditions – essential for QC laboratories, method development, and parallel synthesis.

Technical Specifications – Ordering Information

Note: All models heat to RT +5°C to 100°C with ±1°C accuracy. Heating wire models (18031001, 18031004, 18031007, 18031010) provide economical heating; heating plate models (all others) offer more uniform temperature distribution and faster heat-up.

Trusted Alternative to IKA, Heidolph & Thermo Scientific Hot Plate Stirrers

Hawach hot plate stirrers are widely used as an alternative to premium laboratory brands such as IKA, Heidolph, Velp, and Thermo Scientific, offering comparable performance for routine laboratory workflows and QC applications. With identical speed ranges, temperature accuracy (±1°C), vessel compatibility (up to 1,000 mL per position), and multi-position asynchronous control, Hawach units provide a cost-effective solution without compromising reliability.
