Simultaneous stirring and heating for precise laboratory reactions
The Cell Lab™ Stirring Heating Mantle integrates powerful surface heating with magnetic stirring in one compact unit — ideal for chemical synthesis, reflux, distillation, extraction, and general laboratory heating tasks. Covering a broad capacity range from 50 ml to 20 L, it combines precise thermal control with uniform agitation for consistent, reproducible reaction results.
• Simultaneous Heating and Stirring
Magnetic stirring and heating operate together with stepless speed adjustment (0–1600 rpm), ensuring continuous, uniform mixing during heating — enhancing both reaction kinetics and heat transfer uniformity.
• High-Temperature Nichrome Heating Element
The mantle uses nichrome wire for rapid and even surface conduction, reaching up to 450 °C. The CE-certified aluminium silicate insulation guarantees safe, stable, and efficient heat containment during extended operation.
• Broad Flask Volume Compatibility
Models support 50 ml to 20 000 ml round-bottom flasks. Custom volumes such as 4 L, 6 L, 50 L and 100 L are available on request, providing flexibility for both small-batch and scale-up chemistry workflows.
• Durable Structure & Chemical Resistance
Constructed from cold-rolled steel with anti-corrosion coating and fitted with a PTFE-coated stir bar, this mantle resists chemical wear while maintaining stable mechanical performance.
• Continuous Operation & Global Voltage Support
Designed for continuous working mode, the unit operates on 100–120 V or 200–240 V / 50–60 Hz, ensuring universal compatibility. Its compact form and low noise motor make it ideal for benchtop use.

Continuous heating of viscous or multi-phase solutions
Q1: What is the maximum temperature of the mantle?
A1: The heating surface can reach up to 450 °C, with excellent uniformity and thermal stability.
Q2: Can heating and stirring be used together?
A2: Yes — both functions operate simultaneously for consistent reaction mixing and heat distribution.
Q3: What is the speed range for stirring?
A3: The magnetic stirring speed is steplessly adjustable from 0 to 1600 rpm, suitable for liquids of different viscosities.
Q4: Does it support continuous operation?
A4: Yes — it is engineered for safe, long-term continuous use in research and production labs.
Q5: Can custom large capacity versions be ordered?
A5: Yes — Cell Lab can manufacture bespoke units from 4 L up to 100 L to meet your process requirements.
