Description
BOLA GL 3-way stopcock with T-bore is a PTFE laboratory stopcock engineered for versatile media distribution via GL-thread connections. Equipped with three GL 18 ports and a 4 mm T-shaped bore, it permits controlled switching or combining of flow paths between attached tubing or vessels. The cylindrical plug promotes tight sealing, and a directional marking on the stopcock simplifies alignment of the open channels. Suitable for pressures up to max. 6 bar and vacuum applications, the valve exposes the process fluid solely to PTFE, delivering broad chemical inertness. External dimensions are approximately 74 × 57 × 57 mm (L × D × H); net weight is 0,145 kg. Available as a single unit from manufacturer Bohlender, it fits standard GL laboratory bottle and tubing systems used in synthesis, purification and transfer work. The all-PTFE wetted design and T-bore configuration provide a durable, chemically resistant solution for multi-way flow management in research and quality-control environments.

Questions about BOLA GL 3-Way Stopcocks, GL 18, Ø 4 mm PTFE, cylindrical stopcock plug and GL sc
What is this article?
BOLA GL 3-Way Stopcocks, GL 18, Ø 4 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.
