Questions about BOLA Eco-Czako Stopcock Plugs, NS 14,5 x 29 mm Ø 2,5 mm M 8 Nut, grip and washer
What is this article?
BOLA Eco-Czako Stopcock Plugs, NS 14,5 x 29 mm Ø 2,5 mm M 8 Nut, grip and washer is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
