Tubing for Bio-ChemValve™ Pinch Valves
Platinum-cured silicone tubing
1.
Test Standards. Bio-Chem Valve™ silicone tubing is tested in accordance to the standards set by the United States Pharmacopoeia
National Formulary XVII, 1990, Class VI Biological Test for Plastics. It is FDA Masterfile listed (MAF 819).
2.
Durability. This tubing has been selected for use with pinch valves. Platinum curing performed on the tubing during the extrusion
process imparts superior strength and durability. The tubing has a low compression set and resists sticking shut even after prolonged
periods in the closed position. Excellent memory characteristics ensure full opening and unencumbered flow. The silicone tubing is rated
for 500,000 pinch valve cycles.
3.
Sterilization. The silicone tubing can be sterilized through steam autoclaving, boiling, dry heat, and gamma radiation.
4.
Gas permeability. Silicone tubing has a poor gas permeability rating.
Bio-Chem Valve™ Pinch Valves with an “S” suffix have silicone tubing already installed. The tubing is also available in 50-foot (15-meter) coils.
The coils can be ordered under the part numbers listed below:
C-Flex® tubing
1.
Test Standards. The C-Flex® tubing used in Bio-Chem Valve™ pinch valves is tested in accordance to the standards set by the United
States Pharmacopoeia National Formulary XVII, 1990, Class VI Biological Test for Plastics. It is FDA Masterfile listed.
2.
Material. C-Flex® tubing is made from a thermoplastic elastomer based on styrene-ethylene-butylene. It does not contain leachable
plasticizers.
3.
Chemical compatibility. C-Flex® can be used with many acids and alkalis. It is not recommended for use with oils and organic solvents.
4.
Durability. This tubing has been selected for use with pinch valves. The tubing has a low compression set and resists sticking shut even
after prolonged periods in the closed position. Good memory characteristics ensure full opening and unencumbered flow. C-Flex®
tubing is rated for 200,000 pinch valve cycles.
5.
Sterilization. C-Flex® tubing can be sterilized through steam autoclaving, ethylene oxide (ETO), and gamma radiation.
6.
Gas permeability. C-Flex® tubing has a fair gas permeability rating. It has lower gas permeability than silicone.
Bio-Chem Valve™ Pinch Valves with a “B” suffix have C-Flex® tubing already installed. The tubing is also available in 50-foot (15-meter) coils. The
coils can be ordered under the part numbers listed below:
