Description
Screw caps made of PFA with S 28 thread are laboratory closures intended for secure sealing of bottles and vessels used in analytical and spectrometric routines. Fabricated from perfluoroalkoxy polymer (PFA), they match the S 28 neck finish found on selected laboratory containers and sample bottles. Supplied as 1 pc with a weight of 0,015 kg, the single-piece pack is practical for precise replacement or vessel-specific allocation. These screw caps from manufacturer Vitlab fit consumable needs within spectroscopy and spectrometry workflows, including contexts linked to AAS, ICP, UV-VIS and FT-IR sample handling. PFA construction delivers the chemical resistance and clean-handling profile laboratories rely on when working with demanding reagents and high-purity samples. The S 28 format ensures a firm screw seal during preparation steps, instrumental measurement sequences and short-term holding of materials. As discrete accessories they help keep vessel fleets complete and serviceable without unnecessary stock volume. Use them when a PFA screw cap for S 28 openings is required to support consistent sealing performance in day-to-day analytical laboratory practice.

Questions about Screw caps made of PFA, S 28, 1 unit(s)
What is this article?
Screw caps made of PFA, S 28, 1 unit(s) is the article on this page. Luminix Health distributes Vitlab for laboratory use. It sits in Plastic bottles (narrow & wide mouth), inside Bottles & containers, in Labware.
A plastic bottle is polyethylene, polypropylene or a fluoropolymer, narrow-mouth for pouring or wide-mouth for powders. It is the choice when the bottle must not shatter, and it is the wrong choice for solvents that swell the plastic.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
