Tedlar Gas Sampling Bag 1 Liter

The side port/stem 3/16" allows filling with a pneumatic pump and tubing, and for rapid emptying of the bag. The top of the valve is turned clockwise to close and counter clockwise to open. Continually counter clockwise turning will lead to the top of the valve coming off. One full turn is sufficient to fill the bag. The hole in the top of the valve allows you to inject or extract through a septum with a syringe.

Operating notes:

• Connect tubing to the side stem for filling or evacuating

• Turn valve top at least on full counter clockwise turn to open

• To close the valve, turn valve top clockwise until it stops

• Take a syringe sample by piercing the inner septum built into the valve
