Description
BOLA hollow screws UNF 1/4'' 28G, Ø 1,6 x 3,2 mm are coloured polypropylene fittings for chromatography tubing connections. Fabricated from PP, they feature an external UNF ¼" 28G thread and a yellow finish that aids visual separation of fluid lines in analytical workflows. The geometry is intended for tubing with an inner diameter of 1,6 mm and an outer diameter of 3,2 mm (1/16 x 1/8''), aligning with widely used low-pressure laboratory tubing formats. PA pressure discs are included to promote secure seating against fittings and manifolds during assembly. Offered from manufacturer Bohlender as packs of 10 pieces, order quantities outside this packaging unit are rounded up in steps of ten. With a net weight of 0,0006 kg per piece, the hollow screws add minimal mass while linking tubing to threaded ports. As members of the BOLA chromatography accessory range, they support routine solvent and sample handling where colour-coded polypropylene components help keep multi-line setups clear and orderly on the laboratory bench.
This article is part of HPLC fittings, tubing & inline filters, in HPLC columns & accessories.

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