Description
BOLA Mini 3-way stopcock UNF 1/4'' 28G with Ø 0,8 × 1,6 mm PTFE body and angled design enables flexible multi-path fluid control in laboratory systems. Constructed entirely from polytetrafluoroethylene (PTFE), this three-way valve offers an L-shaped bore and three threaded ports configured as two internal UNF ¼" 28G threads and one external UNF ¼" 28G thread. The FEP stopcock plug contributes to a compact overall height of 20 mm including the handle. Sized for tubing of 0,8 mm inner diameter and 1,6 mm outer diameter (1/32 × 1/16''), the unit measures 42 mm in total length, facilitating neat integration into analytical manifolds and low-volume flow paths. This BOLA component from manufacturer Bohlender is supplied as a single piece and benefits from the outstanding chemical resistance of PTFE. Net weight is 0,012 kg. Typical uses include sample selection, solvent switching, waste diversion and other routing tasks where an angled L-bore geometry reduces dead volume and simplifies panel or instrument mounting. The standardised UNF 1/4'' 28G connections ensure broad compatibility with common laboratory fittings and flangeless connectors.

Questions about BOLA Miniature 3-Way Stopcocks, UNF 1/4'' 28G, Ø 0,8 x 1,6 mm PTFE, elbow
What is this article?
BOLA Miniature 3-Way Stopcocks, UNF 1/4'' 28G, Ø 0,8 x 1,6 mm PTFE, elbow 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.
