What is the typical footprint of this equipment?

Magnetic hotplate stirrers of this model class are generally compact, designed to fit on a standard laboratory bench. Buyers should contact the seller for exact dimensions of this specific unit.

Can this unit be used for unattended operation?

While these units are robust, continuous unattended operation should always be assessed against specific safety protocols and the nature of the reagents being processed. The Heidolph MR Hei-standard does not typically include advanced safety features like automatic shut-off in case of overheating without an external sensor.

Is an external temperature sensor included or required?

For precise temperature control of the sample, an external temperature sensor is highly recommended and often required. While the unit can heat to a set hotplate temperature, an external sensor provides direct feedback from the sample itself. Buyers should confirm if an external sensor is included with this used unit.

What maintenance is typically required for this type of stirrer?

Routine maintenance for magnetic hotplate stirrers generally involves keeping the hotplate surface clean, checking the power cord for damage, and ensuring the stirring magnet is functioning correctly. No specialised maintenance is typically required beyond general laboratory equipment care.

What types of vessels are compatible with the hotplate?

This type of hotplate stirrer is typically compatible with standard laboratory glassware such as beakers, flasks, and bottles, provided they have a flat bottom suitable for contact with the hotplate surface and are made of heat-resistant material.

This listing is for the Heidolph MR Hei-standard Magnetic Hotplate Stirrer.

The unit is in full working condition and is ready for immediate use.

The Heidolph MR Hei‑Standard is a laboratory magnetic hotplate stirrer—a reliable and robust device designed for simultaneous heating and stirring of liquids up to moderate scales.

Key Features & Technical Specs

Heating & Stirring: It heats up to 300 °C on the hotplate (with sample temperatures reaching around 250 °C) and stirs with speeds up to 1,400 rpm, capable of handling volumes up to 20 liters of water.

Heating Power & Plate: Offers around 800–825 W of heating power, using a ceramic-coated silumin (Kera‑Disk®) plate that ensures excellent heat distribution and resistance to scratches and chemicals.

Controls & Accuracy: Features analogue dials for setting temperature and speed (typically from 100 to 1,400 rpm), with speed accuracy of ±2% and temperature setting accuracy of about ±5 °C (or ±1 °C when using an external sensor).
