功能

• When hydrochloric acid is used in a bottle top dispenser or bottle top burette, it is directly attached to the device.
• It is installed so that the acid vapor generated from the solution does not directly enter the equipment and damage the equipment.
• The use of this tube allows acid vapor to escape from the device.
• Please put cotton and more-chiralee sieve into the tube as acid adsorbent. (Not included)
• Can be used with burettes (1620506,1620507).
