Desiccator (Vacuum), PP/PC

The GISCOM Vacuum Desiccator (PP/PC) is a high-performance moisture-free storage and drying chamber designed for laboratories that require controlled vacuum conditions. Engineered for long-term durability, it ensures safe drying of samples, protection of hygroscopic materials, and moisture-sensitive storage. Its robust construction and reliable vacuum retention make it essential for analytical labs, pharma QA/QC departments, research institutes, and industrial testing environments.

Key Features

• Autoclavable construction for long-term repeated laboratory use
• Strong vacuum retention up to 740 mm Hg for 24 hours, without greasing
• Clear, rigid polycarbonate dome provides a full 360° view of contents
• Knurled top knob enables easy and safe handling of the lid
• Lower chamber made from high-strength polypropylene for excellent chemical resistance
• Internal groove designed to securely hold a silicon-rubber O-ring for perfect sealing
• PP stopcock with self-lubricating PTFE plug offering 3-way operation (vacuum creation, shut-off, vacuum release)
• Corrosion-proof and lightweight alternative to traditional glass desiccators
• Stable, non-warping base designed for safe bench use

Handling & Precautions

• Ensure the O-ring is clean and properly seated before vacuum creation
• Do not exceed recommended vacuum limits
• Avoid dropping or striking the dome to maintain optical clarity
• Clean using mild detergent; avoid abrasive pads and organic solvents
• Do not place directly on hot plates; allow temperature equilibration before applying vacuum
• Autoclave following standard PP/PC temperature guidelines
• Store in a cool, dry location away from direct UV exposure

Applications

• Ideal for drying samples, storing hygroscopic chemicals, and maintaining moisture-free environments
• Commonly used in pharma QC/QA labs, chemical analysis, research institutes, biotech labs, universities, and industrial R&D units
• Supports gravimetric analysis, stability testing, and sample conditioning
• Essential for preserving sensitive reagents and preventing experimental variability caused by moisture
