VDR-30 Vacuum Desiccator (Round), 20L (0.7cu ft)

VDR-30 Round Vacuum Desiccator, 20L (0.7cu ft)

The VDR-30 is a state-of-the-art round vacuum desiccator designed for reliable, long-term vacuum retention and sample protection in a laboratory setting. Its robust polycarbonate construction and superior design features provide a cost-effective and user-friendly solution for drying, preserving, and degassing sensitive materials.

Key Features and Benefits:

• Exceptional Vacuum Performance: Achieves and maintains a maximum vacuum of 1 Torr (1.33×10⁻⁴ MPa) for over 72 hours, ensuring a stable and consistent environment for your critical applications.
• Airtight Seal Technology: A high-quality silicone gasket provides a greaseless, airtight seal. This eliminates the need for messy vacuum grease, ensuring a clean test environment and reducing long-term maintenance costs.
• Durable and Clear Construction: Made from highly transparent, shatterproof, and non-corrosive polycarbonate, the desiccator allows for easy viewing of contents while being simple to clean and resistant to most common chemicals.
• Convenient Gas Handling: A versatile three-way stopcock allows for effortless and precise control over vacuum draw, vacuum release, and gas exchange. Barbed fittings on each side ensure secure and leak-free tubing attachment.
• Enhanced Safety and Usability: A built-in flange lock securely holds the lid and base together, preventing accidental separation when not under vacuum. The unit also includes a perforated sample tray and a dedicated tray for drying agents like silica gel.

Available Model Variations:

• UV Protection Models (U/UG): Amber-tinted models are available to block UV light, minimizing damage and discoloration of light-sensitive samples.
• Gauge-Equipped Models (G/UG): These models come with a vacuum gauge conveniently attached to the center of the lid, allowing for at-a-glance monitoring of the vacuum level.
