Product Description
Bottle-style stoppers that will not seize in the joint save time and broken glassware, especially with alkaline or sticky contents. These solid flathead PTFE stoppers seal standard taper medium-length joints and come out cleanly even after long storage. They are a practical upgrade for shared storage bottles.
This listing is for Kimble catalog number 41941R-29: Solid Flathead Stopper, Green Size 29, Case of 6. Each stopper is machined from PTFE, which offers excellent chemical resistance and resists freezing in ground glass joints. A colored button insert on top provides simple color coding, and the ground zone is 40 mm long. Sizes 24 and 29 come in cases of six, and size 14 is sold individually. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
