Bel-Art Scienceware Lab Companion 6L Round Vacuum Desiccator - Ideal for Laboratory Experiments, Chemical Storage & Moisture-Sensitive Materials Preservation

These high-quality vacuum desiccators stay gastight allowing reliable dry storage or experiments over extended periods. Able to maintain 29in.-Hg vacuum for over 72 hours at room temperature, they provide vacuum integrity resulting in lower maintenance and greater peace of mind. Viton 3-way valve offers consistent and uniform vacuum draw, vacuum release, or gas exchange. Vacuum level checking is simplified with a built-in analog vacuum gauge at the top of the unit. High-quality silicone O-ring and specially designed locking ring allow outstanding vacuum capability with virtually no leakage.
