Normax Desiccator with Stopcock 300 mm (49 060 341)
The Normax Desiccator with Stopcock (Cat. No. 49 060 341) is a large-capacity vacuum desiccator constructed from high-quality soda lime glass, designed for precise moisture control, vacuum drying, and sample storage. With an internal diameter of 300 mm, this desiccator provides a spacious chamber suitable for large samples, multiple items, or bulk materials. The integrated stopcock allows easy connection to a vacuum source or inert gas system, while the porcelain plate offers a stable, chemical-resistant platform for laboratory applications requiring dryness and contamination control.
Key Features
Stopcock Assembly: Built-in glass stopcock enables precise control of vacuum pressure or inert gas purging, ensuring stable desiccation conditions.
Porcelain Plate: High-strength perforated plate allows even air circulation beneath samples while resisting chemical corrosion.
Material: Crafted from soda lime glass—durable, transparent, and resistant to most laboratory reagents.
Airtight Ground Joint: Ground-glass flange ensures a secure, airtight seal when used with vacuum grease.
Large Capacity (Ø 300 mm): Accommodates bulky or multiple laboratory items for simultaneous drying or storage.
Transparent Dome Lid: Allows observation of samples during operation without opening the chamber.
Reinforced Design: Thick glass walls provide stability, safety, and long-term reliability under vacuum conditions.
