Borosil Glass Vacuum Desiccator XS with Porcelain Plate & PTFE Spindle

Description

Product Overview

The Borosil® Glass Vacuum Desiccator XS is engineered for precision drying and storage of sensitive laboratory specimens. Constructed from high‑grade borosilicate glass, the vessel offers exceptional chemical resistance and thermal stability, making it suitable for a wide range of scientific applications. Its compact 100 mm diameter footprint (approximately 7.68 × 7.68 × 9.84 in) allows it to fit comfortably on benchtops, while the robust porcelain plate provides a stable, non‑reactive surface for sample placement.

Key structural components include a borosilicate lid equipped with a glass stopcock for controlled vacuum release, and a PTFE spindle that ensures smooth operation and long‑term durability. The desiccator’s design incorporates a sealed glass stopcock that minimizes leakage, delivering consistent vacuum levels essential for reproducible results. The included porcelain plate is engineered to withstand repeated heating cycles without cracking, supporting both low‑temperature desiccation and moderate‑temperature drying processes.

Manufactured by Borosil, a trusted name in laboratory glassware, this model (item number 3083041) adheres to stringent quality standards. The product is lightweight at 3.39 lb, facilitating easy transport between workstations, yet its sturdy construction ensures stability during prolonged use. Originating from India, the desiccator reflects Borosil’s commitment to delivering reliable, cost‑effective solutions for scientific research.

Usage

Designed for versatility, the XS desiccator excels in environments ranging from academic research labs to industrial quality‑control facilities. It is ideal for drying powders, crystals, and other hygroscopic materials that require a moisture‑free environment. The compact size makes it especially valuable in teaching laboratories where bench space is at a premium, allowing instructors to demonstrate vacuum drying techniques without sacrificing functionality.

Typical applications include preparation of samples for spectroscopy, gravimetric analysis, and moisture‑sensitive synthesis. The PTFE spindle provides a low‑friction interface for the stopcock, enabling precise control of vacuum pressure during both evacuation and venting phases. Users can quickly achieve the desired vacuum level, reducing cycle times and improving laboratory throughput.

When handling the desiccator, it is recommended to place the porcelain plate on a stable, heat‑resistant surface before loading samples. The glass stopcock should be operated gently to avoid sudden pressure changes that could disturb delicate specimens. Regular cleaning of the glass interior with appropriate solvents will maintain optical clarity and prevent contamination.

FAQ

What is the maximum vacuum level this desiccator can achieve?

The Borosil XS desiccator is designed to operate efficiently at pressures down to 10 mbar (approximately 0.01 atm). For most laboratory drying applications, this level of vacuum is sufficient to remove moisture quickly and reliably.

Can the porcelain plate be removed for cleaning?

Yes, the porcelain plate is removable. It can be gently lifted out for cleaning with compatible solvents. After cleaning, ensure the plate is completely dry before reinstalling to maintain a moisture‑free environment.

Is the stopcock compatible with standard vacuum pumps?

The glass stopcock is compatible with most laboratory vacuum pumps that use standard hose fittings. It is advisable to use a pump with a pressure range that matches the desiccator’s operating specifications for optimal performance.

How should I store the desiccator when not in use?

When the desiccator is not in active use, keep the lid sealed and store it in a clean, dry area away from direct sunlight and extreme temperature fluctuations. This helps preserve the integrity of the glass and porcelain components.

What warranty does Borosil provide for this product?

Borosil offers a one‑year limited warranty covering manufacturing defects. Should any issues arise within this period, contact our support team for repair or replacement options.
