Description
BOLA GL ball valve, GL 18, bore diameter 4 mm, 2-way type with straight bore, is a compact stopcock for laboratory fluid handling. The spherical plug ensures excellent sealing and smooth operation, while the two GL-threaded ports allow secure connection to compatible tubing or fittings. Only PTFE contacts the flowing medium, giving universal chemical resistance. The valve is rated for pressures up to max. 12 bar and is vacuum-compatible, making it suitable for both pressurised and reduced-pressure systems. Approximate external dimensions are 80 × 44 × 65 mm (L × D × H) and the net weight is 0,182 kg. This BOLA component from manufacturer Bohlender is intended for installation in chemical apparatus, solvent lines and general laboratory process setups where a reliable, chemically inert 2-way shut-off is required. The straight-bore design minimises flow restriction and supports clean, reproducible media transfer in research and production environments.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about BOLA GL Ball Valves, GL 18, Ø 4 mm Type: 2 way, straight bore, cap and grip made
What is this article?
BOLA GL Ball Valves, GL 18, Ø 4 mm Type: 2 way, straight bore, cap and grip made is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
