Description
BOLA Mini 3-way stopcock with UNF 1/4'' 28G connections is a compact PTFE laboratory valve for precise multi-path fluid control in small-bore systems. This T-design version features a T-shaped bore and three internal UNF 1/4'' 28G threaded ports, allowing clear distribution or selection of flow paths in analytical and process laboratory setups. It is sized for tubing with an inner diameter of 0,8 mm and an outer diameter of 1,6 mm (1/32 x 1/16''), supporting fine capillary and micro-scale liquid lines. Overall length is 32 mm and total height including the stopcock is 20 mm, with an FEP plug for dependable sealing and chemical resistance. Supplied as one piece with a net weight of 0,01 kg, the valve is easy to place in dense instrument layouts and compact manifolds. The BOLA Mini range from manufacturer Bohlender is intended for applications that require inert wetted surfaces when handling aggressive media or sensitive samples. Constructed from polytetrafluoroethylene with an FEP plug, this T-bore stopcock offers practical three-way control without metallic contact in the fluid path.

Questions about BOLA Miniature 3-Way Stopcocks, UNF 1/4'' 28G, Ø 0,8 x 1,6 mm PTFE, T-pieces
What is this article?
BOLA Miniature 3-Way Stopcocks, UNF 1/4'' 28G, Ø 0,8 x 1,6 mm PTFE, T-pieces 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.
