Desiccators FAQs


Frequently Asked Questions

A laboratory desiccator is used to preserve low humidity and constant temperature to protect moisture-sensitive substances. It is ideal for cooling oven-dried samples while maintaining sample dryness, storing hygroscopic chemicals, and preventing the adsorption of moisture when using crucibles, weighing bottles, and watch glasses.

The benefits of using a desiccator include:

  • Protecting hygroscopic materials by providing a moisture-free environment.
  • Preserving sample integrity by preventing moisture- and heat-induced degradation.
  • Keeping substances safe from potential contamination by storing them in a designated vessel.

You may use a desiccator to store any moisture-sensitive substances such as hygroscopic salts, deliquescent materials, anhydrous compounds, and metal samples.

Yes, but it depends on the chemical compatibility of the substances and the sensitivity of your samples to cross-contamination.

If there is a risk that storing samples together in the same desiccator might affect the accuracy of your research, we recommend that you keep them in different appropriately labeled desiccators.
