CAT Hotplate Magnetic Stirrers, Magnetic Stirrers,
Hotplates and Safety Hotplate Magnetic Stirrers


Magnetic stirrers are used for stirring (and heating) lower to medium viscosity fluids. A PTFE coated magnetic stir bar (fleas) is placed inside the fluid, this couples with the rotating magnets inside stirrer.

Magnetic stirrers are more compact than overhead stirrers, and can also have heating elements to heat the fluid as you stir.

Magnetic stirrers are not suitable for high viscosity fluids (see our overhead stirrer range ), or for stirring applications that need high shear or very fine dispersion please see our homogeniser range.


CAT have been manufacturing Laboratory equipment in Germany since 1976, and all products are still built in Germany to high quality German Standards and are sold with a 2 year warranty.

CAT stirrers and hotplates feature:
Heating coils embedded in stainless steel tubing for increased safety.
Motors employ electronic feed-back speed control for high speed accuracy.
Powerful magnets allow for maximum performance even with viscous media.
Soft-start feature on most units, preventing stir bar de-coupling and splashing.
Acid resistant epoxy-finished chassis, with grade 304 stainless steel cover.

MCS77/78 Range- Programable Hotplate Magnetic Stirrer

The MCS77 and MCS78 replace the successful MCS67/68 hotplates. Designed as a multi-tasking hotplate stirrer, they have four step timer system which allows for generation of user-defined temperature and stirring profiles. For each timer step the following parameters can be set: hotplate and sensor temperature, motor speed and temperature-slope. Fuzzy-logic control optimally sets the PID algorythms to reach the programmed temperatures as fast as possible but with minimal overshoot.
Other features include:

Easy to read, back-lit alpha-numerical LCD
Rotating, acid-proof membrane keypad/LCD
Timer function
Soft-start brushless motor
Eloxal 500w or Ceran 600w hotplate
Speed range: 50-1600rpm
Selectable hotplate/probe temperature limit
Safety back-up circuit
Monitors for hotplate and sensor short circuit failures
RS485 for remote PC operation/ RS232 with adaptor
Maximum temperature 330°C or 440°C.
Accuracy with PT100 probe: ±0.2°C.
