Vacuum Collar Set for Filter Funnels

Airtight Vacuum Seals for High-Efficiency Buchner Filtration

Stop dealing with vacuum leaks and losing valuable pressure mid-filtration. The official Vacuum Collar Set for Filter Funnels is engineered to create an instant, rock-solid, airtight seal between your Buchner funnels and Erlenmeyer filtration flasks. Designed for seamless workflow integration, this set ensures maximum suction so you can clear out precipitates, fats, and waxes at peak speed.

Universal Multi-Size Compatibility (1000ml to 5000ml)

No need to buy multiple individual adapters for different batches. This versatile, nested filtration collar set is explicitly designed to fit both the 1000ml (1L) and 5000ml (5L) filtration setups sold by Extract Craft. Whether you are running a small benchtop refinement with your Source Turbo or scaling up to massive volume recovery with the EtOH Pro, this kit has the exact size you need.

Durable, Chemical-Resistant Synthetic Rubber

Built to withstand the rigorous demands of laboratory processing and home extractions, every collar in this set is crafted for professional performance:

• Premium Synthetic Rubber: Engineered from high-durability, solvent-resistant synthetic rubber that maintains its elasticity and won't degrade or crack when exposed to standard extraction solvents or alcohol vapors.
• Tapered Nested Design: Features a specialized step-down configuration that molds perfectly to the neck of your filtering flasks, absorbing vibration and preventing the funnel from tipping during deep vacuum draws.
• Fast, Tool-Free Setup: Slip them onto your funnel stems in seconds—no grease, custom plumbing, or tight clamps required to achieve a flawless vacuum seal.
