Description
BOLA hollow screws UNF 1/4'' 28G, Ø 1,6 x 3,2 mm are coloured polypropylene fittings for chromatography tubing connections. These hollow screws are made of PP and carry an external UNF ¼" 28G thread, finished in blue for clear visual coding of fluid lines. They are dimensioned for tubing with inner diameter 1,6 mm and outer diameter 3,2 mm (1/16 x 1/8''), enabling compact, inert plastic joints in analytical flow paths. Pressure discs made of PA are included so that the connection can be seated and sealed reliably during assembly. Supplied from manufacturer Bohlender within the BOLA programme, the parts belong to chromatography accessories used wherever solvent or sample lines must be organised without metal contact at the fitting. Each sales unit contains 10 pieces; quantities outside this pack size are rounded up in steps of ten. With a net weight of 0,0006 kg, the lightweight screws suit dense instrument layouts and routine maintenance of HPLC and related chromatographic systems. Colour-coded blue hardware helps operators distinguish parallel channels quickly during set-up, change-over or troubleshooting in the laboratory.
This article is part of HPLC fittings, tubing & inline filters, in HPLC columns & accessories.

Questions about BOLA Tube End Fittings, UNF 1/4'' 28G, Ø 1,6 x 3,2 mm PP, blue, with washers
What is this article?
BOLA Tube End Fittings, UNF 1/4'' 28G, Ø 1,6 x 3,2 mm PP, blue, with washers 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.
