Description
BOLA Eco straight-through stopcock plug NS 18,8 x 37 mm is a PTFE laboratory stopcock plug with a 6,0 mm bore for ground-joint apparatus needing a larger free passage. A finely finished sealing surface supports consistent seating in NS connections, and the plug is completed with a polypropylene handle and M 10 nut plus a PP washer for straightforward mounting. The straight-through bore design enables controlled liquid transfer in chemical, analytical, and preparative glassware setups where PTFE chemical resistance is preferred. Net weight is 0,035 kg per piece, supplied in packs of 20 pc(s). Sized to NS 18,8 x 37 mm with the specified 6,0 mm bore, it fits corresponding stopcock bodies used across synthesis lines, solvent handling, and general laboratory manifolds. From manufacturer Bohlender, the Eco series combines a PTFE plug body with practical PP accessories, offering a durable replacement or build component for stopcock assemblies that demand a clean flow path and reliable mechanical fastening without elaborate extras.

Questions about BOLA Eco-Stopcock-Plugs, NS 18,8 x 37 mm Ø 6,0 mm M 10 Nut, grip and washer made
What is this article?
BOLA Eco-Stopcock-Plugs, NS 18,8 x 37 mm Ø 6,0 mm M 10 Nut, grip and washer made 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.
