Magnetic Stirrer

Hei-End

P/N: 505-50000-00

Exact settings and individual definition of safety parameters for highly sensitive media 

  • An independent safety circuit switches off heating at an operator-programmed temperature value above your set temperature
  • An additional operational safety step is required to change parameters which prevents unwanted changes to the actual setting
  • The digital display allows for easy setting and monitoring of values on the illuminated readout. Speed setting from 30 to 1,400 rpm at an accuracy of± 1 % and temperature setting up to 300 °C
  • Hotplate residual heat indicator in the digital display illuminates when unit is turned off and hotplate temperature is above 50 °C to prevent accidental operator injury
  • To protect your sample from overheating a safety circuit switches off heating if the temperature sensor is not immersed in your media vessel
  • A separate on/off switch for heating prevents an unintentional heat-up. If heating is switched on the on/off button is illuminated for visual control
  • Upgrade this magnetic stirrer with the optional Pt 1000 temperature sensor for precise temperature control, overshoot protection and reproducible results

Performance and Accuracy

Take advantage of a built-in PID controller that ensures fastest heat-up times while preventing an overtemperature situation of your sample.

 

 

 

 

 

Hei-End - Product Advantages

To prevent accidents or laboratory fires, all magnetic stirrers feature two independent safety circuits which switch off heating in case of any overtemperature situation

In combination with Heat-On attachments you can convert your lab into a “safety zone"

A residual heat indicator for all models prevents you from potential burning hazards

For your safety, the unit will power off in case of a short-circuit, a damage to the temperature sensor, a motor failure or other incidences during operation

A separate on/off switch for heating prevents unintentional heat-up. If heating is switched on, the on/off button is illuminated for visual control

To protect you from splashes and scalding from bath media, rotation speed ramps up slowly until unit has reached the pre-programmed speed

Even if the stirrer is exposed to the highest temperatures, damage is categorically ruled out – all models come with a fire-resistant die-cast housing

All units with digital display allow for easy setting and monitoring values on the illuminated readout

You can even work with dry ice – a robust thermal insulation prevents corrosion inside the housing by preventing condensate from collecting and dripping on any electronic components

A free software program is available for the MR Hei-Connect and MR Hei-End which supports you to automate and to safe your process parameters

The unique Kera-Disk® coating is extremely chemical-resistant and scratch-proof, and therefore the plate can be cleaned easily from solvents, oil or other contaminations

The strong magnetic field allows for easy stirring of even higher viscosity media

In case the heating function fails, stirring will not be discontinued to avoid thermal damage to your sample

The hermetically-sealed housing protects all mechanical and electronic components from aggressive environments

The maintenance-free non-sparking motors reduce down times

The design and features give an increased lifespan of 10 years along with significantly reduced maintenance and repair costs
