The new Scienceware® Pinch Valve from Bel-Art Products, Inc. is designed for use in low-pressure fluid tubing to easily control fluid flow without drips. Three end fittings sizes are available to fit with 1/4-7/16″ ID tubing. To use, squeeze and hold the soft silicone body of the valve to control the flow; release to suspend the flow. The components consist of Teflon®, stainless steel and polypropylene for maximum chemical resistance and can be steam autoclaved at 121C (250F).
