Description
20 ml screw-thread bottles with 20-400 thread are clear glass laboratory containers for sample storage, preparation and general analytical handling. Measuring 86 × 22,7 mm, each bottle provides a practical working volume with a widely used neck finish that accepts matching 20-400 screw caps and septa. The clear glass body allows direct visual inspection of fill level, colour and phase separation during routine laboratory procedures. Manufactured from glass of the 1st hydrolytic class, the bottles offer the chemical durability expected for aqueous and many organic media in everyday lab use. Packaged as 100 pieces per pack, they suit method development, sample archiving and medium-throughput workflows without excess inventory. These screw-thread bottles from manufacturer Altmann Analytik integrate easily into standard laboratory glassware sets and autosampler-compatible setups where a 20-400 closure is specified. Uniform wall thickness and neck geometry support reliable sealing and reduce the risk of leakage during transport or short-term storage. Ideal for quality-control, research and teaching laboratories that need dependable clear 20 ml screw bottles for solvents, standards, extracts and process samples.
This article is part of Autosampler vials, in Vials, caps & septa.

Questions about 20ml screw-top vial, thread configuration 20-400, 86 x 22,7mm, clear glas
What is this article?
20ml screw-top vial, thread configuration 20-400, 86 x 22,7mm, clear glas is the article on this page. Luminix Health distributes Altmann Analytik for laboratory use. It sits in Autosampler vials, inside Vials, caps & septa, in Chromatography equipment.
An autosampler vial is sized for the tray it will sit in. Neck finish, volume, clear or amber glass, and whether an insert is needed are the choices. Amber is for light-sensitive samples. A 2 mL vial is the ordinary one. A vial from a different neck standard takes a different cap.
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.
