Magnetic Stirrer
Hei-Standard
P/N: 505-20000-00
Easy handling and direct access to all parameters due to two separate knobs
- For your protection an independent safety circuit will switch off heating if hotplate temperature exceeds 25 °C over set temperature
- Analog knobs allow for convenient speed setting from 100 to 1,400 rpm at an accuracy of ±2 % and temperature setting up to 300 °C
- 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. In addition, a residual heat indicator prevents from burning hazards when heat function is switched off
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-Standard - 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
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
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
