Safety comes first

It is a known fact that safety is always good. You should keep some safety tips in mind while using a hot plate:-

  • Before heating content in a bath, check for the glassware’s heat resistance, cracks. Also, do remember that do not put any glassware on the plate directly. Apart from this, make sure that the surface of the hotplate is always larger than the vessel being heated.
  • Add boiling stones while bringing the liquids to boil. This will help in facilitating the process.
  • Do not condense any content/ material in a vessel until and unless it is completely dry. Even a single drop of moisture can eventually crack your vessel.
  • For heating liquids, a smart idea would be to set the temperature at medium or medium high setting.
  • Do not heat a metal plate on a hot plate as this can damage the appliance and often poses a shock risk.
  • Always use tongs or any rubber coated, heat resistant gripping devices while removing any object from a hot plate. This goes for pouring hot liquids too.
  • It is advisable not to store any flammable or volatile materials in the vicinity of a hot plate. Also, it is best to chuck out an old and worn-out hot plate for flammable materials.
  • Before using a hot plate, check carefully for corrosions in order to avoid any spark hazard.
  • Last but not the least, always remembers to turn it off after using.

Taking Care of your hot plate

  • A general cleaning way for your hot plate is to wipe the exterior surfaces with a piece of cloth dampened slightly. You can use a mild soap solution.
  • Do not use a vinegar solution for cleaning as it is just a myth.
  • Always keep the hot plate in cool and dry place. Try to avoid it from moisture as to keep it away from corrosion and rust.

As mentioned earlier, the hot plates can be a good companion in lab works and in daily use as they come at a very reasonable price as compared to other heating appliances. You just have to take good and proper precautions and care for it.
