Snorkel Stopper Automatic Pressure Relief Valve For Separatory Funnels

Item #: 21220
Quantity:
$240.00

Availability: 4-5 business days

Product Description

With this 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 the 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 pressure eruptions or explosions.

The Snorkel Stopper features a one-way check valve that automatically relieves gas pressure. The non-sticking, ground-glass valve is backed with a stainless-steel spring and a PTFE closure screw for maximum chemical resistance. 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 sizes listed in the product selection menu correspond to the standard taper stopper size which should be printed on your funnel or stopper.
