Reduce chemical evaporation and exposure to hazardous vapors on multiple carboys.

• Less expensive than ordering individual components
• Color coded caps allow easy solvent identification
• Choose from FFKM, EPDM, or Viton® valve seal options
• Ideal for quaternary systems

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.

Four color-coded GL45 safety caps in blue, red, yellow, and green, with eight connections for ¹/₈" OD tubing, one connection for 2.2 mm OD tubing, and four PTFE plugs.
