Description
Screw caps made of PFA with GL 25 thread are laboratory closures designed for dependable sealing of bottles and vessels in analytical and spectrometric applications. Produced from perfluoroalkoxy polymer (PFA), they correspond to the GL 25 neck finish used on many mid-size laboratory containers and sample bottles. The article is supplied as 1 pc(s) and weighs 0,015 kg, making it convenient for targeted replacement or dedicated assignment to a single vessel. These screw caps from manufacturer Vitlab support consumable requirements in spectroscopy and spectrometry, including work associated with AAS, ICP, UV-VIS and FT-IR sample pathways. PFA offers the chemical resistance and surface characteristics laboratories expect when handling aggressive or high-purity media under standard bench conditions. The GL 25 thread provides a secure mechanical closure for intermediate bottle sizes during sample preparation, measurement cycles and interim storage. As individual labware components they integrate easily into existing vessel fleets without surplus packaging. Select them wherever a PFA screw cap for GL 25 openings is needed to maintain reliable sealing in everyday analytical laboratory operations.
This article is part of Plastic bottles (narrow & wide mouth), in Bottles & containers.

Questions about Screw caps made of PFA, GL 25, 1 unit(s)
What is this article?
Screw caps made of PFA, GL 25, 1 unit(s) is the article on this page. Luminix Health distributes Vitlab for laboratory use. It sits in Bouteilles en plastique (goulot étroit & large), inside Bouteilles et contenants, in Matériel de laboratoire.
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.
