Product Description

A Desiccator With Knobbed Lid is designed for laboratories that require controlled drying and moisture-free storage under vacuum conditions. This laboratory desiccator complies with DIN ISO 13130 standards and is manufactured from high-quality borosilicate glass 3.3. The material provides excellent chemical resistance, strong thermal stability, and long service life in demanding laboratory environments.

Laboratories frequently use vacuum desiccators to protect hygroscopic substances, chemicals, and prepared samples from atmospheric moisture. Because the desiccator supports vacuum conditions, it improves drying efficiency and ensures reliable sample preservation.

The thick-walled borosilicate glass construction increases mechanical strength and enhances durability. As a result, laboratories can maintain safe vacuum storage even during extended experimental procedures.

Researchers, educational laboratories, and industrial testing facilities often use this equipment as part of their routine laboratory workflow. Laboratories interested in exploring a wider range of laboratory glassware can also review the complete product range available here:

Design and Construction of Desiccator With Knobbed Lid

The Desiccator With Knobbed Lid features a carefully engineered construction that supports reliable vacuum operation. The vessels have high wall thickness, which improves strength and pressure resistance during vacuum use.

Both the lid and the base include precisely machined vacuum-tight ground joints. These joints create an effective seal between the two components. Because of this accurate sealing system, the desiccator allows storage under vacuum for extended periods without leakage.

The knobbed lid design allows easy handling during laboratory procedures. Technicians can lift or close the lid conveniently while maintaining secure alignment with the base.

Vacuum Operation and Drying Efficiency

This Desiccator With Knobbed Lid includes a stopcock that allows laboratories to apply vacuum inside the chamber. By creating a reduced-pressure environment, the drying process becomes faster and more efficient.

The desiccator is suitable for full vacuum conditions up to 0 mbar. Therefore, laboratories can safely use it for sensitive drying procedures and moisture-controlled storage.

Because vacuum conditions reduce moisture pressure, chemicals and samples dry more effectively compared to normal atmospheric storage.

Interchangeable Components and Maintenance

Laboratories benefit from the modular design of this desiccator. Spare parts such as lids, bases, stopcocks, and caps can be replaced when necessary. This interchangeability simplifies maintenance and extends the operational life of the equipment.

When replacing components, laboratories should ensure that the correct DN size is selected for proper compatibility and sealing performance.
