PBVCs will not allow liquid release at pressure up to 10PSIG
PBVCs allow hydrogen gas to permeate at greater than 5 E-06 mol/sec/mol fraction
Eliminated the need for operators to "Remember" to close and open the screw top closure when transporting a bottle from one area to another
Eliminates costly spills and cleanup of contaminated solution
Chemical compatibility tested with 12 molar HCL, HNO3, KOH, CCL4, TCE and organic hydrocarbons
Available in Fluorinated HDP E for super chemical/Solvent compatibility
Poly-Bottle Ventilation Caps (NucFil-PBVCs), prevent liquid release if a bottle is inadvertently tipped over, yet a thermally bonded semi-permeable membrane allows hydrogen and other explosive gasses to diffuse out of the bottle. The risk of explosive mixtures of gas is eliminated, yet over-pressurization of the bottle cannot occur. Also, the risk of the polyethylene bottle becoming brittle and failing is eliminated.
