Stopper Pressure Relief

Not yet rated

With a patented Glas-Col Snorkel Stopper, you'll never again have to take time to open the stopcock and relieve pressure when vigorously shaking a separatory funnel, because our Snorkel Stopper does the task automatically. If you use a Glas-Col shaker, you can simply load the funnels onto it and get on with more important things without worrying about exploding glass.

The Snorkel Stopper features a one-way check valve that automatically relieves gas pressure. The valve releases pressure of more than 1 pound and prevents direct air contact with the vessel.

The shape of the stopper allows manual or machine shaking and avoids solution leakage. For manual shaking, the stopper is held in place by hand. On Glas-Col shakers, glassware holders automatically restrain the stopper.

  • The non sticking, ground glass valve is backed with a stainless steel spring and a PTFE closure screw for maximum chemical resistance
  • Fits Standard Taper Stopper Size: 13
