"Gas Samplers"

Woulff gas wash bottles with two necks for preparing gases.

When used with a pneumatic trough, our gas generating bottle set is ideal for generating small quantities of hydrogen and other gases.

Remove impurities from gases.

This is the same bottle that ships with the Vernier CO₂ Gas, O₂ Gas, and Ethanol Sensors.

The bottle's adjustable sprayer permits a range of positioning from fine mist to large stream delivery to accommodate a variety of washing applications.
