Overview & Features
Grease-Free PTFE Stopcock: The most prominent feature is the PTFE (Teflon) stopcock plug, which has an extremely low coefficient of friction. This allows for smooth operation without the need for joint grease, completely eliminating the risk of sample contamination from lubricants.
Absolute Chemical Durability: The combination of the Borosilicate Glass 3.3 body and the PTFE stopcock creates a system highly resistant to almost all strong acids, bases, alkalis, and polar/non-polar organic solvents used in extraction procedures.
Accurate Phase Separation: The uniform tapered design at the bottom leading to the stem enables operators to easily observe the interface between the two liquid phases, allowing precise control of the stopcock to collect or discard each layer cleanly.
Airtight PE Stopper: The included plastic stopper matches the ground joint size of the funnel neck perfectly, ensuring maximum airtightness and preventing solvent leakage during vigorous shaking for sample mixing and dissolution.
