Features:
Enclose harmful or toxic vapors .
Teflon and Tefzel construction with PE or PP cap rings.
Special design prevents twisting of tubing.
Includes teflon tubing for solvent reservoir.
Various port and bore sizes, materials and configurations 
Colored with GL standard screw threads(GL45/GL40/GL38/GL32/GL28). PTFE insert with numbered holes(1-6 holes). 
Most labs use this bottle cap (also called Solvent Delivery Caps) to ensure that their mobile phase is not contaminated and thereby helps to comply with their HPLC GLP requirements. 
Your mobile phase will only contact medical grade PTFE so there will not be any contamination from plastic or wax film.
Keeping these caps on the bottles with the tubing through holes prevents dust and dirt from getting in and minimizes out gassing or absorption of CO2 from the atmosphere. 
The cap assembly can be auto-claved.
Closed System Design
Reduce chemical evaporation and exposure to hazardous vapors with CFDPLAS solvent reservoir caps. 
Combine with secure fluid connections and CFDPLAS air inlet or relief valves to maintain pressure equilibrium within the bottle.
Anti-Twist Design
To prevent twisting of tubing when the cap is removed or attached, the inner body rotates independently of the outer collar.
Chemically Compatible
Constructed of inert PTFE, the body of the cap provides ideal chemical compatibility with laboratory solvents. 
Under normal use, the outer Polypropylene collar is non-wetted. 
Caps may be autoclaved to 140°C. 
Please inquire for other material options and custom designs.
