Description
b.safe Cap B83 is a laboratory bottle cap for B83 threads, built for multi-line capillary solvent or rinse supply. The screw cap is made of polyethylene (PE) and holds a freely rotatable PTFE insert. PFA fittings accommodate capillaries with 3,2 mm outer diameter on UNF 1/4'' threads; four yellow Ø 3,2 mm fittings are included together with three milky-white PFA blind fittings to seal unused ports. A ventilation valve with change indicator supports controlled air exchange during liquid withdrawal. Scope of delivery and configuration follow the manufacturer table (four capillary connections plus fittings as specified). This cap from manufacturer Bohlender is intended for organised, chemically resistant tubing connections on B83-neck containers in analytical and preparative laboratory fluid handling, helping keep capillary lines secure and unused ports closed.
This article is part of HPLC fittings, tubing & inline filters, in HPLC columns & accessories.

Questions about b.safe Cap B83, 5x UNF1/4'' Cap B83 made of PE, insert made of PTFE with 4
What is this article?
b.safe Cap B83, 5x UNF1/4'' Cap B83 made of PE, insert made of PTFE with 4 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.
