Normax Desiccator with Stopcock (49 060 311)

Normax Desiccator with Stopcock 250 mm (49 060 311)

The Normax Desiccator with Stopcock (Cat. No. 49 060 311) is a high-quality laboratory desiccator designed for vacuum drying and moisture-controlled storage of samples. Made from durable soda lime glass, it combines strength, transparency, and chemical resistance for reliable everyday laboratory use. With a 250 mm internal diameter, this model offers a larger working capacity, suitable for drying multiple or bulk samples. The integrated stopcock allows connection to vacuum or inert gas lines, while the porcelain plate provides a stable, chemical-resistant surface for sample placement.

Key Features

• Vacuum-Compatible Design: Equipped with a precision stopcock for controlling vacuum pressure or gas purge, ensuring efficient moisture removal.

• Porcelain Plate: Features a perforated, high-strength porcelain plate that allows even air circulation beneath the samples.

• Soda Lime Glass Construction: Provides excellent transparency and resistance to laboratory reagents.

• Ground Glass Flange: Ensures a tight and secure seal when used with vacuum grease, maintaining a stable low-humidity or vacuum condition.

• Spacious Interior (Ø 250 mm): Ideal for laboratories requiring moderate-to-large drying or storage capacity.

• Transparent Dome Lid: Allows easy observation of samples without disturbing the internal atmosphere.

• Rugged Build: Thick glass walls provide mechanical strength and long-term reliability under repeated vacuum applications.

Specifications

Applications

• Designed for vacuum drying of hygroscopic, thermally sensitive, or chemically reactive materials.

• Used in chemical, pharmaceutical, and educational laboratories for controlled drying and storage.

• Ideal for cooling samples after heating and storing moisture-sensitive chemicals.

• Suitable for desiccant-based systems using silica gel, calcium chloride, or phosphorus pentoxide.

Maintenance and Handling

• Apply a thin film of vacuum grease on the flange before sealing for airtight closure.

• Clean using mild detergent and soft sponge; avoid abrasives to prevent scratching the glass.

• Ensure stopcock components are regularly checked and lubricated for vacuum integrity.

• Avoid sudden temperature changes to prevent thermal stress or cracking.

• Store securely on a stable, flat surface.
