Glass Buffer Bottle – High Borosilicate Safety Bottle with PTFE Valve Option
Product Description:
The Glass Buffer Bottle (also known as a safety bottle or vacuum pump protection bottle) is an essential component in laboratory vacuum filtration systems. Designed to prevent liquid backflow (suck-back), it effectively protects vacuum pumps from damage caused by aspirated liquids.
Made of high-quality borosilicate glass, the buffer bottle is durable, smooth, and transparent, allowing for clear observation of internal conditions. It can be used with vacuum filtration units and vacuum aspirators by connecting soft tubing between the vacuum pump and the receiving flask for filtrate or waste liquid.
Features:
✅ High-Quality Borosilicate Glass: Excellent thermal and chemical resistance for long-term lab use.
✅ Anti-Backflow Design: Protects vacuum pumps by preventing liquid suck-back during filtration.
✅ Smooth and Transparent Surface: Easy to observe and clean.
✅ Good Sealing Performance: Ensures airtight operation under vacuum conditions.
✅ PTFE Valve Option: Available with or without valve to meet different experimental needs.
