DESICCATORS: Glass, Polypropylene

DESICCATORS: Glass, Polypropylene

• Sturdy glass or polypropylene Desiccators for use in the laboratory.
• Designed to control humidity and remove moisture from hygroscopic sample materials.
• Provides low humidity airtight atmospheric pressured storage using a suitable drying agent at bottom.

(Wikipedia excerpt: .."...Desiccators [D] are sealable enclosures containing desiccants used for preserving moisture-sensitive items such as cobalt chloride paper for another use. A common use for [D] is to protect chemicals which are hygroscopic or which react with water from humidity. The contents of [D] are exposed to atmospheric moisture whenever the [D] are opened. It also requires some time to achieve a low humidity. Hence they are not appropriate for storing chemicals which react quickly or violently with atmospheric moisture such as the alkali metals; a glovebox or Schlenk-type apparatus may be more suitable for these purposes.

Desiccators are sometimes used to remove traces of water from an almost-dry sample. Where a desiccator alone is unsatisfactory, the sample may be dried at elevated temperature using Abderhalden's drying pistol...")
