Pinch Valve
Pinch valve allows control of fluid flow without drips.

• Squeeze soft silicone body to permit flow
• Release pressure to suspend flow
• Withstands approximately 16 lbs. of pressure
• Made of Teflon®, stainless steel and polypropylene for maximum chemical-resistance
• Steam autoclavable at 121°C (250°F)

Metric Gauge Tube Sizer
A handy metric diameter gauge that will end doubt about inside or outside diameters.

• Measures glass and plastic tubing, connecting pieces, rods, test tubes, etc. between 1.5 and 16mm
• Holes on one side measure O.D.; pins on the other side measure I.D
• Order one for your tubing and one for your test tubes, centrifugation tubes and adaptors
• Polypropylene plastic; autoclavable at 121ºC (250ºF)
