Hei-Connect

Magnetic Stirrers

Hei-Connect with Pt1000 temperature sensor (V4A)

P/N: 505-40081-00

Stirring and heating with full control

In our proven Hei-PLATE magnetic stirrer line, the Hei-Connect combines gentle stirring (up to 1,400 rpm) with a precise heating function (up to 300 °C). Unique in its robust design and secure functionality, this model stands out with additional features giving you complete control and an easy, accurate documentation of your process parameters.

The unique Kera-Disk® footprint is chemically resistant, scratch-proof, and has a diameter of 145 mm. This unique size makes it suitable for use with many accessories and samples on a small footprint. The anodized aluminum from which it is made enables the fastest possible heating times.

The Hei-Connect magnetic stirrer provides a digital display for setting your desired temperature exactly to the degree. This precise temperature without overshooting is controlled by two selectable heating modes (FAST/PRECISE) and the optional external temperature sensor Pt1000.

To facilitate process control and documentation, the Hei-Connect is equipped with a timer and an RS 232 interface. The free Hei-Control Software is included in the scope of delivery.

  • This variant includes the Pt1000 temperature probe

Hei-Connect - 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 Hei-Connect and 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
