Normax Desiccator with Stopcock 200 mm (49 060 241)
The Normax Desiccator with Stopcock (Cat. No. 49 060 241) is a durable and transparent laboratory desiccator made from high-quality soda lime glass, designed for vacuum drying and moisture-controlled sample storage. With a 200 mm internal diameter, it provides sufficient space for drying or storing medium-sized samples. The integrated stopcock allows for controlled evacuation or introduction of inert gas, while the porcelain plate ensures stable sample support and efficient air circulation during desiccation.
Key Features
Vacuum-Ready Design: Fitted with a glass stopcock for easy connection to a vacuum pump or inert gas system, enabling precise humidity and pressure control.
Porcelain Plate: Removable perforated plate provides a stable, chemical-resistant surface and allows uniform airflow under samples.
Soda Lime Glass Body: Transparent and resistant to most laboratory chemicals, suitable for daily laboratory operations.
Airtight Seal: Ground-glass flange ensures tight sealing when used with vacuum grease, maintaining low humidity inside the chamber.
Moderate Capacity (Ø 200 mm): Ideal for general laboratory desiccation and moisture-protection needs.
Clear Dome Lid: Allows visual monitoring of contents without disturbing the internal environment.
Durable Construction: Thick glass walls ensure mechanical strength and long service life under controlled vacuum conditions.

Applications
Vacuum drying of hygroscopic and heat-sensitive materials.
Storage of moisture-sensitive samples and reagents.
Cooling of heated glassware or substances in a low-humidity environment.
Commonly used in chemical, industrial, pharmaceutical, and educational laboratories.
Suitable for use with desiccants like silica gel, phosphorus pentoxide, or calcium chloride.
Maintenance and Handling
Apply a thin layer of vacuum grease on the ground joint before sealing.
Inspect and lubricate the stopcock regularly for smooth operation.
Avoid sudden temperature changes to prevent glass cracking.
Clean gently using mild detergent and rinse thoroughly with distilled water.
Store upright on a stable surface to prevent mechanical stress.
