Normax Desiccator Lid with Stopcock 250 mm (49 063 31)

Normax Desiccator Lid with Stopcock 250 mm (49 063 31)

The Normax Desiccator Lid with Stopcock (Cat. No. 49 063 31) serves as a replacement lid for vacuum desiccators with an internal diameter of 250 mm. Made from soda lime glass, this lid combines strength, optical clarity, and chemical resistance to support drying and storage under controlled humidity or vacuum conditions. The integrated glass stopcock lets users regulate vacuum pressure or introduce inert gases, ensuring precise control for sensitive laboratory applications.

Key Features

• Stopcock Assembly: Provides easy control for vacuum regulation or inert gas flow during desiccation.

• High-Quality Glass: Soda lime glass construction delivers durability, transparency, and resistance to most laboratory chemicals.

• Perfect Fit: Designed to fit 250 mm desiccator bases, forming a tight seal through the ground-glass flange.

• Airtight Sealing: When greased properly, the ground joint prevents air and moisture from entering the chamber.

• Transparent Dome: Offers full visibility of samples without needing to open the lid.

• Rugged Structure: Thick glass walls enhance safety and durability in laboratory use.
