Product Description
Keeping air out of a nitrogen or argon line while still seeing that gas is flowing is the job of a good oil bubbler. This airless bubbler mounts directly on a 24/40 joint, giving a visible flow check and a one-way barrier against back-diffusion of air.
This listing is for Kimble catalog number 652210-0000: KONTES Airless Gas Bubbler With Ground Joint. About 10 mL of oil seals the lower inner tube, and bubbles rising through it show the gas flow rate. The bubbler is made from 33 expansion low-extractable borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A, with a 24/40 ground joint and an 8 mm OD tubing connection. Body OD is 22 mm. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
