Your advantages - our Hei-lights



  • To prevent accidents or laboratory fires, all magnetic stirrers feature an overtemperature circuit which switches off the hotplate if an overtemperature situation occurs
  •  In combination with Heat-On attachments you can convert your lab into a "safety zone"
  • Even if the stirrer is exposed to the highest temeratures, damage is categorically ruled out - all models come with a fire-resistant aluminum die-cast housing
  • Hotplate residual heat indicator in the digital display is illuminated when unit is turned off and hotplate temperature is above 50 °C to warn operator of potential burn hazards

  • For your safety, the unit will power off in case of a short-cut, a damage to the temperature sensor, a motor failure or other incidences during operation
  • To protect you from splashes and scalding from bath media, rotation speed ramps up slowly until unit has reached the pre-programmed speed
  • In case the heating function fails, stirring will not be discontinued to avoid thermal damage to your sample
  • 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
