Description
BOLA Eco straight-through stopcock plug NS 18,8 x 37 mm provides a PTFE stopcock body with a 4,0 mm through-bore and a finely finished surface for reliable seating in matching ground glass joints. Built for straight-through media passage, the plug is supplied with a polypropylene handle, M 10 nut and washer so that the insert can be tightened and operated without metal contact parts on the actuation side. The stopcock material is polytetrafluoroethylene (PTFE); handle, nut and washer are polypropylene (PP). Ground joint dimensions are NS 18,8 x 37 mm with M 10 thread and a bore diameter of 4,0 mm, aligning the Eco plug with common laboratory glassware of this joint size. Net weight is 0,036 kg per piece. Units are packed as 20 pc(s), convenient for workshop stock or multi-station laboratories. From manufacturer Bohlender, this Eco straight-through stopcock plug supports replacement and new assembly of PTFE plugs where a larger bore and M 10 fastening are specified, combining inert PTFE sealing geometry with PP handle hardware for everyday chemical laboratory use.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about BOLA Eco-Stopcock-Plugs, NS 18,8 x 37 mm Ø 4,0 mm M 10 Nut, grip and washer made
What is this article?
BOLA Eco-Stopcock-Plugs, NS 18,8 x 37 mm Ø 4,0 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.
