Chemglass Life Sciences 0-4mm Chem-Vac Valve
0-4mm Chem-Vac Valve. CHEM-VAC valve has single sidearm sealed at a 90 angle to the barrel. This inexpensive configuration allows for the lower portion of the barrel to be sealed directly to the apparatus being constructed, making for more compact, stronger assemblies. Valve has a TFE plug with three o-rings, the tip o-ring making the primary seal on the precision formed tapered seat. O-rings on the non-rotating shaft form an excellent dynamic seal between the TFE plug and glass barrel. Available with a choice of Viton or Kalrez o-rings. See CG-935 for replacement plug, CG-537 for o-ring replacement kit, and CG-902 for glass portion only.
