overview

Parallel experimentation is where most synthesis labs lose time. The MS-H340-S4 replaces four separate stirrers with one instrument, giving each position its own LCD readout of real-time temperature and speed. Chemists screening reaction conditions, developing drug candidates, or optimising scale-up routes can run four variables at once and read every channel at a glance. Ceramic-coated plates resist aggressive reagents, and the sealed brushless motor eliminates brush wear, making the unit suitable for the continuous duty cycles typical of R&D and QC laboratories.

Features & Benefits

4 Independent Channels

Each of the four positions has its own heating and stirring control, allowing four different reaction conditions to run simultaneously on one instrument.

Real-Time LCD Readout

The LCD display shows the actual temperature and stirring speed as they are running, so deviations are visible immediately without an external monitor.

PID Temperature Control

A PID controller delivers a precise and stable heating profile across the full range up to 340 °C, minimising overshoot on sensitive reactions.

Brushless DC Motor

The brushless drive runs quietly and requires no brush replacement, providing more powerful and consistent speed control over long unattended runs.

External PT1000 Probe

An external temperature sensor measures the medium directly to an accuracy of 0.2 °C, rather than inferring it from the plate surface.

Overheating Protection

An independent safety cut-out triggers at 420 °C to protect samples, the instrument, and the operator from thermal runaway.

Ceramic-Coated Work Plate

The stainless steel plate carries a ceramic coating that provides good chemical resistance against spilled solvents and corrosive reagents.

Extensive Accessory Range

A wide variety of accessories is available to adapt the stirrer to different vessel types and workflow requirements.

Highlights

4 Channels

Four fully independent heating and stirring positions in a single benchtop unit.

Up to 340 °C

PID-controlled heating across the full range for precise, stable temperature profiles.

0.2 °C Accuracy

External PT1000 probe measures medium temperature directly for reliable control.

420 °C Cut-Out

Independent overheating protection safeguards samples and operators.

Frequently Asked Questions

  • Can each of the four positions be set to a different temperature and speed?

    Yes. Heating and stirring are controlled independently at every position, so four sets of conditions can run at the same time on one instrument.

  • How accurate is the temperature control?

    The unit uses PID control for a stable heating process, and the external PT1000 sensor measures the medium temperature to an accuracy of 0.2 °C.

  • What happens if the plate overheats?

    An overheating protection function cuts in at 420 °C, above the 340 °C maximum working temperature, to protect the sample and the instrument.

  • Is the work plate resistant to chemical spills?

    The stainless steel plate is ceramic-coated, which gives it good chemical resistance to solvents and reagents encountered in organic synthesis.

  • Does the motor need servicing?

    No. The brushless DC motor is maintenance-free, quiet, and designed for reliable long-term operation.
