Beschrijving
BOLA Eco lateral stopcock plugs (NS 12,5 x 27 mm) are precision PTFE plugs with a 1,5 mm bore, intended for laboratory stopcock assemblies that require a fine surface finish and reliable sealing. Each plug is supplied with a polypropylene handle and M 8 nut, a PP washer, and an outlet tip with an inner diameter of 1 mm, supporting controlled lateral flow in glassware setups that use the corresponding ground joint size. The PTFE body provides the chemical resistance and low-friction surface typical of fluoropolymer stopcock components, while the PP fittings allow convenient hand tightening and secure seating of the plug. Dimensions follow the NS 12,5 x 27 mm format with M 8 threading, matching standard laboratory joint geometry for this size class. Offered from manufacturer Bohlender as a practical Eco-line accessory for routine wet-chemistry and apparatus work, these lateral stopcock plugs suit assembly, maintenance, and replacement on compatible stopcocks. Net weight is 0,015 kg per unit. The pack contains 10 pieces, making the item convenient for stocking multiple benches or shared glassware stations without over-specifying performance beyond the stated construction and dimensions.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about BOLA Eco Stopcock Plugs for lateral burettes, NS 12,5 x 27 mm Ø 1,5 mm M 8 Nut,
What is this article?
BOLA Eco Stopcock Plugs for lateral burettes, NS 12,5 x 27 mm Ø 1,5 mm M 8 Nut, is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Rubber- & siliconenstoppen, inside Stoppen, doppen & sluitingen, in Labmateriaal.
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.
