Description
Screw caps in black polypropylene (PP) for ND13 neck finish provide a solid, closed closure for autosampler vials and sample bottles when a bore hole and septum are not required. Supplied without borehole and without septum, these caps form a continuous barrier over the vial opening, making them suitable for secure storage, transport or intermediate holding of samples outside active injection sequences. The ND13 screw thread matches common laboratory vial formats used in analytical and general laboratory practice. Packaged as 100 pc(s) with a pack weight of 0,070 kg, the black PP design offers straightforward visual identification on the bench and in storage. From the ROTH SELECTION range, the caps are intended for applications where a simple mechanical seal is preferred over a pierceable septum—for example temporary capping, blank storage or non-instrument use. Their uniform black colour and standard ND13 geometry allow easy integration into existing vial inventories, racks and trays. Laboratories standardising on ND13 consumables can use these closed screw caps alongside open-hole variants to cover both sealed storage and sampling workflows without changing vial types.
This article belongs on Vial caps & septa, in Vials, caps & septa.

Questions about Screw caps, PP, black, ND13, without borehole, without septum, 100 unit(s)
What is this article?
Screw caps, PP, black, ND13, without borehole, without septum, 100 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatography equipment.
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.
