Description
b.safe Space-saving cap GL45, 3× UNF 1/4" is a GL45 screw cap designed for space-efficient multi-line HPLC solvent withdrawal. A yellow PP-GF cap body holds a flat, freely rotatable PTFE insert whose threaded connections exit sideways at 90° to the bottle thread, reducing the height needed above the bottle. The system includes PFA fittings for capillaries with 3,2 mm outer diameter, PFA blind fittings to seal unused ports, and a ventilation valve with change indicator. Configuration data specify two capillary connections, two yellow fittings for Ø 3,2 mm tubing, and one milky-white blind fitting. This arrangement supports dual capillary take-off plus controlled ventilation on standard GL45 reagent bottles while unused ports remain closed. From manufacturer Bohlender, the cap is supplied as one piece for laboratory HPLC solvent handling where compact side-exit routing is preferred.
This article is part of HPLC fittings, tubing & inline filters, in HPLC columns & accessories.

Questions about b.safe Space-saving Caps GL45, 3x UNF 1/4'' Cap GL45 made of yellow PP-GF,
What is this article?
b.safe Space-saving Caps GL45, 3x UNF 1/4'' Cap GL45 made of yellow PP-GF, is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in HPLC fittings, tubing & inline filters, inside HPLC columns & accessories, in Chromatography equipment.
HPLC fittings and tubing are numbered by bore. A wide bore after the column broadens the peaks. Finger-tight and wrench fittings, and stainless against PEEK, are different pressure ratings. An inline filter is the last screen before the column, and it clogs on purpose so the column does not.
An HPLC column is a tube packed, or coated, with a stationary phase. The sample is carried through it by a liquid, and the compounds leave at different times. The phase, the particle size, the length and the internal diameter decide the separation. A guard column is a short sacrificial piece in front of the analytical column. Fittings and tubing have a bore that either preserves the peak or smears it. Compound names follow IUPAC. Data are on PubChem. Method grades often cite the European Pharmacopoeia or USP.
