Description
Closures for sample vials with 20 mm neck size (NS) are intended for lyophilisation and combine aluminium crimp caps with chlorobutyl stoppers. They seal vials with article numbers IVMN and IVMA, forming a dependable barrier during freeze-drying and related vacuum steps. Chlorobutyl elastomer delivers the sealing behaviour needed for lyophilisation workflows, while the aluminium crimp caps lock the stopper in place after crimping. Supplied in packs of 100 pieces with a net weight of 0,238 kg, the set supports efficient preparation of multiple samples in pharmaceutical, analytical and research laboratories. These lyophilisation closures from manufacturer Labbox address routine needs for standard 20 mm neck vials used in freeze-drying protocols. Consistent stoppering and crimping help maintain sample integrity through sublimation and storage. The aluminium–chlorobutyl combination is a familiar choice for containers that must withstand vacuum and controlled atmosphere conditions. Suitable for laboratories standardising on IVMN and IVMA vial formats, the pack format fits both small-batch development and higher-throughput sealing stations.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Drying closures for injection vials Ø 20 mm, 100 pcs
What is this article?
Drying closures for injection vials Ø 20 mm, 100 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatographie.
A vial cap and a septum have to match the vial neck: crimp, screw or snap, and the diameter. The septum material, PTFE/silicone or rubber, decides chemical resistance and how many times a needle can pierce it. A septum that sheds into the solvent becomes ghost peaks.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
