Poly-Bottle Ventilation Caps (PBVCs) provide safe ventilation of hydrogen and other gases generated in liquids that contain dissolved plutonium or uranium.
  PBVCs will not allow liquid release at pressures up to 10 psig.
  PBVCs allow hydrogen gas to permeate at greater than 5 E-06
mol/sec/mol fraction.
  Eliminates 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 HCI, HNO3, KOH, CCI4, Trichloroethane and other organic hydrocarbons.
  Available in fluorinated HDPE for super chemical/solvent compatibility.
  Available in 1", 2" and 3" bottle cap sizes.

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 gases to safely diffuse out of the bottle. The risk of generating a flammable mixture of gas is eliminated and over-pressurization of the bottle cannot occur. Also, the risk of the polyethylene bottle becoming brittle and failing is eliminated.
