Helpful tips

While lab fridges and freezers come in a variety of shapes and sizes, you may wish to consider the following before you buy:

  • Size—balance available lab space with capacity required.
  • Temperature—knowing how your lab fridge or freezer is used will provide a clear idea of what temperature range is needed.
  • Cost—keep in mind the “second cost” or the cost of the energy your equipment uses when comparing initial purchase price.
  • Energy efficiency—keeping air in a space artificially cold takes some serious energy, especially when you need extremely low-temperature freezers. ENERGY STAR certified models are tested to use the least amount of energy, saving you money.
  • Special features—other options are available, including external digital thermometers, locks, glass doors and temperature alarms.
