Bohlender GL45 Bottle Cap with UNF Port and Stopcock

Connect 1/8" outer diameter fluororesin tubing with the included PFA fitting, or 1/16" outer diameter fluororesin tubing with the separately sold fitting.
The included air valve also balances the negative pressure inside the bottle while preventing the inhalation of contaminants.
There is an 8mm high space on the side of the yellow cap where you can write or attach a label with a permanent marker.
The body is made of PTFE with a Viton O-ring on the inside.
The cap is made of polyphenylene sulfide (PPS).
When attaching or detaching the cap, the cap can be rotated freely while preventing the tube already connected to the port from twisting.
Although the port with a cock cannot have a tube pass through the body, there is a 1/4-28UNF female thread on the inside of the cap, and a 1/8" outer diameter fluororesin tube can be connected using the included PFA fitting (semi-transparent).
It is used as a bottle cap for sending and receiving liquid from various HPLC and analytical equipment by turning on and off each cock.
