Description
Le préfiltre de pression BOLA avec raccordements UNF 1/4"-28G est une unité PTFE en ligne conçue pour une filtration fine immédiate directement en amont des colonnes HPLC. Il accepte des membranes filtrantes de 13 mm de diamètre et d'environ 0.2 mm d'épaisseur, offrant une surface de filtration de 132 mm² pour un fonctionnement virtuellement sans volume mort. Les deux côtés portent des filetages UNF 1/4"-28G et le boîtier est adapté à un tuyau d'un diamètre intérieur de 1.6 mm (1/16"). La membrane peut être échangée rapidement sans outils, ce qui facilite la maintenance de routine dans les flux de travail chromatographiques. Fabriqué en polytetrafluoroethylene (PTFE) par Bohlender, le préfiltre compact associe résistance chimique et faible poids net de 0.028 kg. Il est fourni en une seule pièce et est destiné aux accessoires de chromatographie de laboratoire lorsque une rétention fiable des particules et un volume de rétention minimal sont requis avant les colonnes analytiques ou préparatives. Adapté aux montages de manipulation continue de liquides qui exigent des surfaces mouillées inertes et un remplacement simple de la membrane.

Questions about Préfiltres de pression BOLA, UNF 1/4''28G, I-Ø 1.6 mm PTFE, diam. de filtration
What is this article?
Préfiltres de pression BOLA, UNF 1/4''28G, I-Ø 1.6 mm PTFE, diam. de filtration is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Raccords HPLC, tuyaux & filtres inline, inside Colonnes HPLC & accessoires, in Chromatographie.
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.
