Metering in gas and liquid chromatography can be optimized by use of these particular micro sample tubes.
A practical small-volume micro sample tube particularly designed for sample application in the gas and high pressure liquid chromatography.
The conical shape allows optimizing the sample quantities (e.g. concentrated extracts or solid mater or residue dissolved in the mobile phase) and the injection volume resulting in minimal aliquot losses and high detection sensitivity.
The mode of manufacturing and the selected plastics (micro sample tubes made of polypropylene, closure caps made of polyurethane) guarantee high resistance to aqueous and organic solvents, a feature particularly important for sensitive detectors.
The specially developed closure cap can be easily pressed-on by hand and provides an air-tight seal for the snap-on lid. It is easy to pierce and closes again after the penetration.
