Buchner Flask with socket

Vacuum Filtration Excellence with Integrated Socket Design

When you're running multiple filtrations daily, you need glassware that won't crack under pressure or leak at critical moments. Buchner flasks with socket joints solve both problems with heavy-walled borosilicate construction and precision-ground connections that create reliable vacuum seals every time.

The integrated socket design eliminates the rubber stopper hassle you'd face with a standard Filter funnel with glass disc setup. Just match your socket taper to your funnel, and you're ready to pull vacuum without worrying about leaks during long filtration runs.

Heavy-Walled Construction for Vacuum Applications

Standard thin-walled glassware collapses under vacuum pressure, but these flasks feature reinforced walls throughout the body to handle full vacuum without imploding. The borosilicate glass (Type I, 3.3 expansion coefficient) resists thermal shock up to 500°C, so you can filter hot solutions directly without waiting for cooldown.

The plain side arm connection provides smooth vacuum flow without turbulence that could disturb your precipitate. Unlike Round Bottom Flask with two necks or Round Bottom Flask with three necks setups that require adapters, this single-purpose design optimizes vacuum distribution across your filter bed.

Side Arm Connection and Pump Integration

• Direct hose attachment to vacuum pumps or aspirators through the reinforced side arm
• Angled arm positioning keeps tubing clear of your workspace and prevents kinking
• Smooth bore interior maintains consistent vacuum levels during extended filtrations
• Compatible with standard laboratory vacuum systems from 10-760 mmHg

Capacity Selection for Different Sample Volumes

Choose from 125ml to 2000ml capacities based on your typical batch sizes. Small 125-250ml flasks work well for analytical samples and microscale prep, while 1000-2000ml volumes handle preparative chemistry and larger environmental samples.

Socket joints come in 14/20, 19/22, and 24/29 standard tapers to match your existing funnel inventory. For specialized distillation work requiring multiple connections, consider Round Bottom Flask with three necks, vertical sockets or Flask pear shape alternatives, but for dedicated filtration, the single-socket Buchner design provides unmatched vacuum efficiency and stability.
