What Is a Two-Hole Rubber Stopper Used For?
School and college chemistry uses two-hole stoppers in gas-preparation set-ups such as hydrogen or carbon dioxide generation, in wash bottles, and in filtration and aspirator assemblies where air must enter as liquid leaves. Lubricate each tube with water or glycerine and ease it in with a twisting motion, holding it in a cloth near the stopper. Rinse and dry stoppers after use and store them out of sunlight.

Frequently Asked Questions
Why choose two holes rather than one?
Two bores let one stopper carry two tubes, so liquid can be added or gas led off while the vessel stays closed.
Does any size match the one-hole stopper?
Yes. The 21 x 26.5 x 27.5 mm size is also made as a one-hole Rubber Stopper, so both can serve the same flask neck.
How is the correct size chosen?
Pick the size whose bottom diameter enters the neck easily while the wider top stays outside, giving a tight seat without pushing the stopper fully in.

JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, makes it in Ambala, Haryana, along with matching flasks and glass tubing.
