Bohlender GL38 Gallon Bottle Cap with UNF Port

The thread standard for the amber gallon bottle with handle is GL38, and it can be used with most reagent bottles and burette bottles (thread standards 38-400, 38-410, 38-415, 38-430) sold in Japan.
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.
Since each tube from the pressure or suction source passes through the body and the height inside the bottle can be freely adjusted, it is suitable as a liquid or gas supply/discharge container or a bottle cap for bubble traps.
There is a 6mm high space on the side of the blue cap where you can write with a permanent marker or attach a label.
The cap is heat resistant up to +200°C.
