Heavy Wall Clear Amber Borosilicate Glass Vacuum Desiccator with Porcelain Plate

Description

Overview

Designed for rigorous drying, degassing, and moisture-free storage, this Heavy-Wall Glass Vacuum Desiccator provides a secure environment for light- and moisture-sensitive compounds. Constructed from high-expansion, chemical-resistant 3.3 borosilicate glass, it withstands full vacuum pressures while resisting thermal shock. Available in Clear for maximum visibility or Amber for UV protection of photosensitive materials.

Key Features

• 3.3 Borosilicate Glass: Superior resistance to thermal stress, chemical corrosion, and mechanical stress under vacuum.

• UV Protection (Amber Option): Blocks harmful UV and short-wavelength light (typically up to 500 nm) to prevent photodegradation of sensitive compounds.

• Vacuum Stopcock Included: Fitted with a precision-ground glass or PTFE stopcock plug and hose connector for seamless connection to vacuum pumps.

• Perforated Porcelain Plate: Includes a chemical-resistant, heat-resistant perforated porcelain disk that sits above the desiccant chamber to support crucibles, weighing bottles, and samples.

• Ground-Glass Flange: Precision-ground rim ensures an airtight seal when paired with standard vacuum grease.

Specifications

Operating Tip: Always apply a uniform layer of vacuum grease (such as silicone or Dow Corning grease) to the ground-glass flange joint before evacuating to ensure a complete hermetic seal and prevent sticking.
