More About this Item

Create a closed system using solvent reservoir caps to prevent hazardous vapors from escaping into the lab. Caps accept standard 1/4"-28 UNF(M) fittings to easily connect semi-rigid tubing. Anti-twist design allows the inner body of the cap to rotate independently preventing tubes from tangling when caps are removed or attached. Caps are constructed of PTFE body and PP collar* and are autoclavable.

Caps with integrated air inlet valve and filter permit air to enter the bottle for vacuum displacement while solvent is pumped to the instrument. Valves are made of PTFE and 300-series SS components and feature a 50 µm PTFE filter to reduce particulate contamination. Select from FFKM, EPDM, or Viton® valve seal options.

*Does not come in contact with liquid under normal circumstances.
