Product Description
An integrated high-vacuum valve lets you isolate the bubbler when it is not needed, so oil does not get sucked back into the line during evacuation. This bubbler gives inert-gas users visible flow monitoring plus a positive shutoff in one compact unit.
This listing is for Kimble catalog number 652230-0000: KONTES Airless Gas Bubbler. The inner tube reaches to within 5 mm of the bottom, so only a small amount of mineral oil is needed. The bubbler is made from 33 expansion low-extractable borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A, with a 25 mm OD body and a 9 mm OD valve arm. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
