Heating Operation Principles

                 Display (°C)                                                                           Actual Top Surface Temp. (°C)

• The heating element and a temperature sensor are located just beneath the ceramic top surface of the product. The microprocessor-controlled heat, generated by the heating element, is based on the sensor temperature and the value set on the heater.ng
• Temperature Display. When the sensor temperature is not within the range of the value set on the display, the display will flash. When the sensor temperature is within range, the value displayed will remain constantly on.
• The Heating Temperature Display does not indicate the actual temperature of materials placed on top of the product or the actual temperature of the ceramic top surface. The following table shows a typical difference between the temperature set on the Heating.
• Temperature Display and the actual temperature measurement of the ceramic top surface. This information was taken using a D0420 with no top load in 20°C ambient conditions.
• To directly control the temperature of liquid in a vessel on the top surface, place the External Temperature Controller into the liquid and connect the Controller to the product.
• The Heating Temperature Display shows the temperature of the liquid and can be used to adjust the temperature of the liquid.

FAQs

What are the main functions of the Labnet AccuPlate stirrer hot plate?

The AccuPlate is perfect for mixing and heating liquids concurrently in analytical, biological, and chemical labs because it combines precision magnetic stirring and adjustable heating into one device.

What is the maximum temperature the hot plate can reach?

The hot plate is appropriate for a variety of laboratory heating applications because it can reach temperatures of up to 550°C.

How do I control the stirring speed and temperature?

Depending on the model, the unit’s independent stirring speed and heating temperature controls enable users to accurately regulate each parameter using either separate knobs or digital controls.

What types and sizes of stir bars are compatible with the AccuPlate?

Magnetic stir bars that are oval or cylindrical and between 10 and 40 mm in length are ideal for the AccuPlate. Depending on the volume and viscosity of your solution, choose the right size.

Is the hot plate surface resistant to chemicals and scratches?

Indeed, the surface is usually composed of ceramic or aluminium and coated with a chemical-resistant material that is intended to endure common lab solvents and prevent scratches for long-term use.

Can the AccuPlate stir and heat simultaneously?

Of course. For processes that need continuous agitation at high temperatures, the system’s ability to simultaneously stir and heat is crucial.

Can I use the AccuPlate with glassware other than beakers?

Yes, as long as the flasks or bottles have a flat bottom that keeps them in touch with the hot plate surface for uniform heating, you can use other lab glassware.
