Description
b.safe ventilation valve with UNF 1/4'' connection thread is a compact laboratory accessory designed for controlled air exchange on compatible b.safe Caps. The valve housing is made of polypropylene (PP) and carries a UNF 1/4“ 28G thread that mates directly with the corresponding b.safe Cap systems. A lid provides a dedicated ventilation opening together with a Luer-lock connection, while an integrated check valve and an upstream porous PTFE membrane (1 µm) help manage airflow and particle retention during routine solvent handling. A clip-on change indicator is included so users can monitor the recommended service interval of six months. Supplied as a sales unit of two pieces from manufacturer Bohlender, the set is intended for laboratory waste and solvent-cap assemblies where reliable pressure equalisation is required. Net weight is 0,0163 kg per unit configuration. The component supports clean, organised HPLC and general lab workflows that rely on b.safe Cap interfaces without adding bulk to the bottle neck.
This article is part of HPLC fittings, tubing & inline filters, in HPLC columns & accessories.

Questions about b.safe Air Valve, UNF 1/4'', (PU=2 pcs.) PP, with connection UNF 1/4 for b.safe
What is this article?
b.safe Air Valve, UNF 1/4'', (PU=2 pcs.) PP, with connection UNF 1/4 for b.safe 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.
