Features:
Airtight container used to keep substances dry
Fitted with a lid that seals tightly to prevent moisture entry
Contains a compartment for desiccants like silica gel or anhydrous calcium chloride
Used to store moisture-sensitive materials or cool hot crucibles in a moisture-free environment
Maintains a low-humidity atmosphere inside
Common in labs handling hygroscopic chemicals or samples requiring dry storage
Transparent or opaque lid for visibility or light protection
Available in vacuum and non-vacuum types
Specifications:
Material: Borosilicate glass, polypropylene, or polycarbonate
