Magnetic Stirrers

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-Tec - Product Advantages

In order to categorically exclude accidents and fire, all models have two independent safety circuits that automatically switch off the hotplate in the event of an unwanted rise in temperature

A combination with Heat-On attachments makes the application even safer

All models are equipped with a visual residual heat indicator to prevent burns

For safety reasons, the device is switched off completely in the event of a short circuit, broken sensor of the temperature sensor, defective motor and in the event of a processor fault

A separate On / Off button for the heating function prevents unintentional heating. The activated heating function is clearly recognizable by the illumination of the button

To prevent any splashing, the rotation speed ramps up slowly until it has reached the desired value

Damage to the device is impossible even at the highest temperatures – all models are equipped with a fire-resistant die-cast housing

Even with the fastest heating times compared to conventional magnetic stirrers, the built-in PID controller guarantees precise control without overshooting the temperature

The unique Kera-Disk® coating is extremely resistant to chemicals and scratches. The hotplate is therefore easy to clean and dirt can be easily removed. A PID controller ensures precise control of the heating process

The powerful stirring magnet allows the stirring rod to be safely entrained even with larger quantities of up to 20 l

If the hotplate fails, the stirring process is not interrupted. This prevents the sample from overheating

Efficient cold insulation prevents condensation in the housing and thus contact between condensation water and electronic components – ideal for working with dry ice

On devices with a display, all parameters can be read from the large, illuminated display, even from a greater distance

With the free software support for the Hei-Connect model, processes can be reliably automated and documented – for up to four devices simultaneously

Clearly shorter process times. The high heating power of 800 Watt enables 35 % faster heating times compared to conventional magnetic stirrers with 600 Watt

Thanks to its aluminum core, the Kera-Disk® hotplate guarantees the fastest heating times. Due to the resistant ceramic coating, the plate is chemical-resistant and scratch-proof

Corrosion-protected electronics add many years to the operational lifespan and reduce expenditure for new purchases

Wear- and maintenance-free motors save repair and spare part costs

The average operational lifespan is on average more than 10 years, thus making your purchase a worthwhile investment

The sealed housing of the magnetic stirrers guarantees a long service life with low susceptibility to repairs

Top FAQ

The calculated surface area of the Findenser Standard is 0.45 m² while the Findenser Mini offers a calculated surface area of 0.22 m².

Yes, the magnetic stirrers Hei-Mix S and Hei-Mix L has no heating function.

For larger quantities we recommend alternatively the magnetic stirrer Hei-Mix L.

B joints are standard joint sizes in many countries. B joints are also sometimes referred to as ‘NS’ joints instead, so e.g. B29 (B29/32) is the same as NS 29/32, and B24 (B24/29) is the same as NS 24/29.

The fins are very sturdy and can only be bent with great effort. However, bent fins do not have a negative effect on the air condenser’s performance.

More important than the factor room temperature is the fact that the Findenser is used in the fume hood. The regular air exchange ensures that heat is dissipated to the required extent.

Findenser is resistant to the majority of solvents and splash-resistant to dilute acids and alkalis at room temperature. Extended exposure to acids or alkalis will attack the outer metal surface of the Findenser.  It is important to clean off any chemical spills immediately after they occur.

The inner body of Findenser and the cone/socket, i.e. the wetted parts that come into contact with the substance being evaporated during normal use, are borosilicate glass 3.3, which has very

The Heat-On addons and bath attachments fit on all Heidolph Hei-PLATE magnetic stirrers with heating function.
All Heat-On addons have a fixing edge, which means that they are accurately centered on plates and can no longer slip.

 

The silicone rubber straps are recommended for the lower StarFish clamp. They grip glassware, and are very durable. The silicone clamps have a handle for lifting glassware away from the heat.

The Velcro straps are recommended for the upper clamp. They are designed to not grip glassware tightly, allowing condensers to slide through the straps when glassware is lifted, whilst still offering some support. Please note the Velcro straps are not suitable for suspending unsupported glassware

One of the advantages of StarFish is that you can mix and match parts to build the system that suits your application.

If you would like to have water condensers in your StarFish system, you will need two water manifolds (one for water in, and one for water out). If you want to use vacuum or inert gas too, then you will also require a gas/vacuum manifold.
