Description
ND18 20 ml fine thread bottle is an amber glass laboratory vial for sample containment where reduced light exposure is preferred. It measures 75,5 x 22,5 mm and features a rounded bottom for stable seating in standard racks and compatible instrument trays. Amber glass helps limit light transmission relative to clear glass during preparation, short-term storage and transport of light-sensitive solutions. The ND18 fine thread is widely used with matching screw caps and septa in chromatography and general analytical sample handling. Pack size is 1000 pc(s), supporting laboratories that standardise vial geometry across high sample volumes. This bottle from manufacturer Altmann Analytik is presented as an alternative to Agilent article 5188-6537, which can simplify cross-referencing when replacing or aligning consumables in existing methods. Country of origin is Germany. Pair with suitable ND18 closures selected for your solvent system and analytical protocol.
This article is part of Autosampler vials, in Vials, caps & septa.

Questions about ND18 20ml Precision Thread Vial, 75,5x22,5mm, amber glass, rounded bottom
What is this article?
ND18 20ml Precision Thread Vial, 75,5x22,5mm, amber glass, rounded bottom 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.
