Description
Product Overview
The Deschem 400mm Glass Vacuum Desiccator Jar is a premium laboratory glassware item designed for precise drying and storage of sensitive chemical and biological samples. Constructed from high‑grade borosilicate glass, the jar offers exceptional resistance to thermal shock, chemical corrosion, and mechanical stress, making it suitable for a wide range of scientific applications. The clear glass body provides full visibility of the contents, allowing users to monitor drying progress without opening the system.
Key specifications include an inner diameter of 400mm, a total height of approximately 500mm, and a weight of 17.64 pounds, providing a substantial volume while remaining manageable on standard laboratory benches. The jar comes equipped with a precision‑machined lid that creates an airtight seal when paired with the integrated stopcock, enabling the creation of a reliable vacuum environment essential for moisture removal and sample preservation.

Usage
This desiccator jar is ideal for use in chemistry, biochemistry, materials science, and pharmaceutical research laboratories. It excels in applications such as drying hygroscopic solids, storing moisture‑sensitive reagents, and maintaining inert atmospheres for air‑sensitive compounds. The robust construction allows the jar to be placed in ovens, autoclaves, or temperature‑controlled chambers without risk of breakage.
Researchers often employ the jar during sample preparation steps that require removal of residual solvents or water. By evacuating the air through the stopcock, a low‑pressure environment is established, accelerating the desiccation process while protecting samples from oxidative degradation. The clear glass design also facilitates visual inspection, reducing the need for disruptive opening of the system.
In educational settings, the jar serves as a teaching tool for demonstrating principles of vacuum drying, gas exchange, and material stability under reduced pressure. Its user‑friendly lid and stopcock mechanism make it accessible to students and technicians alike.

FAQ
Can the desiccator jar be used in an oven?
Yes, the jar’s borosilicate glass is rated for temperatures up to 500 °F (260 °C), making it safe for use in standard laboratory ovens for drying processes.
What type of vacuum pump is recommended?
A low‑to‑medium vacuum pump capable of achieving pressures between 0.1 and 1 mbar is sufficient for most drying applications. Ensure the pump’s oil is compatible with the chemicals you intend to use.
Is the stopcock compatible with standard vacuum tubing?
The stopcock features a ¼‑inch (6 mm) male thread that fits common vacuum tubing and adapters, allowing easy integration with most laboratory vacuum systems.
How do I clean the jar after use?
Rinse the jar with distilled water, followed by a mild detergent solution if needed. Rinse thoroughly and allow to air‑dry before re‑assembly. Avoid abrasive cleaning tools that could scratch the glass surface.
What is the warranty period for this product?
Deschem provides a one‑year limited warranty covering manufacturing defects. Contact our support team for warranty claims and replacement procedures.
