Description
BOLA Eco straight-through stopcock plug NS 14,5 x 29 mm is a PTFE laboratory stopcock plug with a 4,0 mm bore, intended for ground-joint glassware where a clean, straight flow path is required. The plug features a finely finished surface for reliable seating and is supplied with a polypropylene handle and M 8 nut together with a PP washer, so the assembly is ready for installation in standard NS fittings. PTFE construction supports chemical resistance in typical wet-chemistry and analytical setups, while the Eco configuration keeps the accessory set practical for routine laboratory work. Each unit has a net weight of 0,018 kg and is offered in a pack of 20 pc(s). Dimensions follow the NS 14,5 x 29 mm ground-joint size with the stated 4,0 mm bore diameter, matching common stopcock bodies used in synthesis, titration, and sample-handling lines. Available from manufacturer Bohlender, this straight-through Hahnküken-style plug suits replacement or new build of PTFE stopcock systems where controlled passage and durable sealing surfaces are essential without unnecessary complexity.

Questions about BOLA Eco-Stopcock-Plugs, NS 14,5 x 29 mm Ø 4,0 mm M 8 Nut, grip and washer made
What is this article?
BOLA Eco-Stopcock-Plugs, NS 14,5 x 29 mm Ø 4,0 mm M 8 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.
