Z225010 Aldrich

Aldrich® check-valve bubbler

single-inlet tube, top outlet

Synonym: bubblers, scientific bubblers



General description

Position the bubbler on it′s side with the left hose barb (as shown in the drawing) pointing straight up, then pipette 15 mL of oil through the hose barb into the bubbler reservoir. Position bubbler vertically as shown in drawing and it is ready to use.

Principal of operation

Gas enters the bubbler from the hose barb on the right and flows through the bubbler, exiting at the left. The gas pressure unseats the check-valve ball to release the pressure, bubbling up through the oil and out the left side. The check-valve ball reseats itself when pressure is neutralized. The advantage of a check-valve over bubbler such as Z223719 which does not have one, is that it prevents oil from being drawn from the bubbler reservoir into the reaction if a sudden negative pressure occurs.
