Description
VZK N20 is a sealing head for 20 mm crimp caps, intended for the electronic high-performance crimping tool 735700. This interchangeable head allows the instrument to close vials fitted with 20 mm crimp seals in a controlled, repeatable manner, supporting laboratory tasks such as sample storage, chromatography preparation, and general analytical packaging. Delivered as a single unit, the head is designed for mounting on the specified electric crimper so operators can match the tool to the required cap diameter. The accessory comes from manufacturer Macherey-Nagel within its range of laboratory sealing components. Net weight is 0,31 kg, and the compact pack format keeps the spare or dedicated head easy to keep near the workstation. It is a non-sterile laboratory part for use in standard lab environments. Use the VZK N20 whenever the electric crimping tool 735700 must be configured for 20 mm crimp caps and a dedicated Verschließkopf for that size is required.
This article belongs on Crimpers & decappers, in Vials, caps & septa.

Questions about CRH N20 (f. electr. cr. tool 735700)
What is this article?
CRH N20 (f. electr. cr. tool 735700) is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Crimpers & decappers, inside Vials, caps & septa, in Chromatography equipment.
A crimper closes a crimp cap onto a vial neck. A decapper takes it off. The jaw size, 11 mm or 20 mm, has to match the cap. A crimp that is too tight cracks the neck. One that is too loose leaks in the tray. Electronic and manual tools differ in how repeatable the squeeze is.
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.
