Description
BOLA Mini 2-way stopcocks with UNF 1/4'' 28G threads and dimensions for 1,6 × 3,2 mm tubing are compact PTFE valves for controlled fluid handling in laboratory systems. The two-way stopcock is made of polytetrafluoroethylene with a straight bore and two connections, available either as two internal UNF ¼" 28G threads or as one internal and one external UNF ¼" 28G thread. Overall height including the shut-off handle is 20 mm, and the stopcock plug is manufactured from FEP. Total length is 32 mm, suited to tubing with inner diameter 1,6 mm and outer diameter 3,2 mm (1/16 × 1/8''). These mini stopcocks from manufacturer Bohlender support tight instrument layouts and low-volume fluid paths where chemical resistance and reliable isolation matter. PTFE construction is appropriate for analytical, preparative and general laboratory fluidics with aggressive media. Each unit is supplied as one piece with a net weight of 0,01 kg, ready for integration into modular tubing runs, chromatography lines and micro-scale process setups requiring compact UNF-threaded shut-off components.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about BOLA Miniature 2-Way Stopcocks, UNF 1/4'' 28G, Ø 1,6 x 3,2 mm PTFE
What is this article?
BOLA Miniature 2-Way Stopcocks, UNF 1/4'' 28G, Ø 1,6 x 3,2 mm PTFE 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.
