SP Bel-Art Lab Companion Clear Polycarbonate Cabinet Style Vacuum Desiccator; 45 Liter (F42400-4031)

This high-quality vacuum desiccator provides vacuum integrity lasting three times longer than the average vacuum desiccator resulting in lower maintenance and greater peace of mind. Able to maintain 29in.-Hg vacuum for over 72 hours at room temperature, it stays gastight allowing reliable storage or experiments over extended periods. A Viton 3-way valve offers consistent and uniform vacuum draw, vacuum release, or gas exchange. Transparent polycarbonate construction is durable, easy to clean, chemical-resistant, and allows quick visualization of the desiccator contents. Includes desiccant tray.
