Description
BOLA chromatography connectors with GL 25 thread are PTFE-based fittings for reliable fluid connections in chromatography and general laboratory fluid handling. A black PPS screw cap with GL thread secures the unit to glassware, while the PTFE distributor body provides one internal UNF 1/4'' 28 G port for mini-fittings. An elastic sealing lip together with a supporting O-ring compensates for unevenness on the glass surface and maintains a tight closure. Construction ensures that the medium contacts only the PTFE body, delivering very good chemical resistance. These connectors from manufacturer Bohlender operate at working temperatures up to +200 °C and accept tubing measuring 1,6 mm inner diameter by 3,2 mm outer diameter. Each piece weighs 0,018 kg net and is supplied as a single unit. The larger GL 25 format suits bottles and vessels commonly used in preparative work, solvent reservoirs and sample transfer lines where inert wetted materials and secure mini-fitting attachment are required.

What is this article?
BOLA Chromatography Adapters, GL 25, 1 x UNF 1/4'' 28 G PTFE. For tubing outer is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
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.
