The Labshark plastic vacuum desiccator (also referred to as a lab vacuum desiccator, laboratory desiccator, or vacuum desiccator chamber) is a high-performance instrument designed for vacuum drying preservation of biochemical reagents, pharmaceuticals, and sensitive materials. Made of imported polycarbonate by injection molding, this desiccant chamber features a 4mm wall thickness (15% increase) with rib reinforcement design for enhanced pressure resistance.
With a vacuum stability of less than 6% change over 31 days, this vacuum desiccator ensures long maintenance time and reliable performance. The grease-free sealing system uses silicone rubber O-rings, while the dedicated metal needle valve and quick-connect fitting support dual-valve installation for vacuum evacuation and inert gas introduction. Available in 150mm, 250mm, 300mm, and 400mm sizes, this desiccator jar is the ideal vacuum desiccator for laboratory applications.

All models feature the same vacuum stability, polycarbonate construction, and dual-valve compatibility.
Place the vacuum desiccator on a stable, flat surface.
Check that the silicone O-ring and sealing gaskets are properly seated.
Connect the vacuum pump to the needle valve using the quick-connect fitting and nylon tubing.
Place your samples inside the desiccator chamber.
Ensure the samples are properly contained to prevent spillage.
Position the lid carefully onto the base.
Close the needle valve.
Turn on the vacuum pump and evacuate the chamber to the desired vacuum level.
Monitor the vacuum gauge (if equipped) to confirm the vacuum level.
For oxidation prevention, connect an inert gas source to the second valve (if installed).
Slowly introduce inert gas into the chamber, then close the valve.
After use, release the vacuum slowly before opening the lid.
Clean the desiccator with a mild detergent and soft cloth.
Do not use abrasive cleaners or solvents that may damage the polycarbonate.
Precautions:
Do not exceed the maximum vacuum level recommended for the desiccator.
Always release vacuum slowly to prevent sample disturbance.
Do not use the desiccator with corrosive chemicals that may attack polycarbonate.
Inspect the O-rings regularly and replace if worn or damaged.
