Description
BOLA GL 3-way stopcock with L-bore is a PTFE laboratory valve designed for controlled flow routing in chemical and analytical setups. It features three GL 25 threaded connections and a 6 mm L-shaped bore, allowing selective direction of media between ports. The cylindrical stopcock plug ensures reliable sealing, while a clear marking indicates the flow path for straightforward operation. Rated for pressures up to max. 6 bar and suitable for vacuum service, the unit keeps the process medium in contact exclusively with PTFE, providing broad chemical resistance across aggressive reagents and solvents. Approximate external dimensions are 78 × 59 × 57 mm (L × D × H); net weight is 0,166 kg. Supplied as a single piece from manufacturer Bohlender, this stopcock integrates readily into GL-thread tubing and bottle systems used in synthesis, sampling and transfer lines. Its all-PTFE wetted path and robust cylindrical plug make it a practical choice for laboratories requiring inert, leak-tight multi-way control without metal or elastomer exposure.

Questions about BOLA GL 3-Way Stopcocks, GL 25, Ø 6 mm PTFE, cylindrical stopcock plug and GL sc
What is this article?
BOLA GL 3-Way Stopcocks, GL 25, Ø 6 mm PTFE, cylindrical stopcock plug and GL sc 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.
