Vacuum Desiccator Cabinet (Vacuum Exsiccator)

Protect moisture-sensitive samples with a high-quality Vacuum Desiccator Cabinet, precision-engineered and manufactured in Switzerland 🇨🇭. Also known as a Vacuum Exsiccator, this transparent laboratory desiccator provides a clean, dry environment for storing samples under vacuum or in an inert gas atmosphere such as nitrogen or argon.

Manufactured from polished PMMA GS acrylic, the desiccator combines excellent visibility with a rigid construction for reliable everyday laboratory use. It is available in Standard, Extra-Wide, and Portable versions, allowing you to choose the ideal size for your application.

Key Features

• Swiss-made quality 🇨🇭 – precision-engineered for laboratory and research applications.
• Fully transparent PMMA GS construction – excellent visibility of stored samples.
• Vacuum storage – maintains approximately 25 mbar for several months after evacuation with a diaphragm vacuum pump.
• Controlled atmosphere – suitable for storage under dry nitrogen or argon.
• Rigid construction – thick PMMA walls provide excellent stability.
• Removable shelves – two transparent shelves included (height-adjustable in the Extra-Wide model).
• Integrated pressure gauge – monitor the internal pressure at any time.
• Overpressure protection – safety valve opens automatically at approximately 200 mbar overpressure.
• Convenient vacuum connections – supplied with two right-angle valves with 6 mm tube connections (Portable version: one straight valve with quick connector).

For optimum performance, we recommend combining the desiccator with one of our LABOPORT® diaphragm vacuum pumps, providing fast evacuation and reliable long-term vacuum storage.
