Application cases
This device plays an important role in many laboratory processes. In the following, we mention some of the main applications of the digital magnet hot plate:
- Agitation of solutions: to dissolve solids in liquids, mix solutions and create suspensions
- Heating solutions: to accelerate chemical reactions, evaporate solvents and melt solids
- Dissolving gases in liquids: To dissolve gases such as oxygen or nitrogen in liquids
- Calorimetry: To measure the heat of reactions
- Preparation of culture media: To prepare microbial culture media
How to use
Hot plates are not as dangerous as open flame heating methods. However, there are certain precautions you should take when using the equipment:
- Take precautions when heating flammable organic liquid. Do not heat them in an open pan as their vapors can escape and ignite when in contact with any other heating element. Always use a condenser. However, a water bath is recommended for heating such solvents.
- The temperature and stirrer controls of hotplates vary from brand to brand, therefore, the performance of each control should be well-diagnosed before use.
- Before using the device, make sure that the “on” and “off” switches work and that the heating pads of the device cool down quickly.
- Make sure the glass you use to heat your solution is made of heat-resistant materials such as borosilicates. Do not use glasses made of soda lime glass or “soft glass” because they cannot withstand frequent temperature changes and break easily.
- Avoid using thick-walled glass containers as they may heat unevenly, causing them to crack during use.
- Make sure the hot plate is bigger than the heating pot.
- Before using the pan to heat ingredients, make sure they are not already cracked or broken.
- Add the solvent or reagents to the heating vessel using a drop funnel (closed system) when the hot plate is already hot. It prevents materials from catching fire or absorbing moisture.
- Use tongs or thermal gloves to remove hot dishes from the hot plate.
- Learning the location and operation of the laboratory fire extinguisher is essential to control any accidental fire situation.
- Do not use hot plates manufactured with technology before 1984. Buy models that are explosion-proof and have more safety features.
- Do not heat metal or foil pans on a hot plate with a temperature of 200 degrees Celsius. It can damage the device.
- Do not heat items beyond the specific temperature specified by the manufacturer.
- Be careful of electrical wires and temperature sensor probes that touch the surface of the hot plate when it is hot.
Important points while using the digital magnet hot plate
- Using the right containers: Use heat-resistant containers such as Erlenmeyer, Bescher and Ballon.
- Appropriate volume of liquid: The volume of liquid should not exceed the amount specified in the manual of the device.
- Using the right stirrer: The size of the stirrer should be proportional to the volume of the liquid and container used.
- Attention to safety: avoid direct hand contact with the heated plate and observe safety precautions if flammable materials are used.
