Description
Colorimeter tube according to Eggertz 100:0,2 ml with NS stopper constitutes precision glassware for colorimetric analysis and standardised colour comparison. It carries a graduation of 100:0,2 ml, an NS 19/26 ground joint and a corresponding NS stopper to ensure reliable closure. Supplied as 1 pc and weighing 0,11 kg net, the tube is produced by manufacturer Witeg in Germany (Baden-Württemberg). This larger-capacity Eggertz colorimeter tube is appropriate for analytical methods that employ Nessler-type vessels for visual evaluation of solution colour or turbidity. The 0,2 ml increments up to 100 ml enable accurate volume handling in both research and quality-control environments. The NS 19/26 joint provides broad compatibility with common laboratory stoppers and connectors. Robust clear glass offers good optical clarity and mechanical durability for everyday laboratory use. Single-piece packaging supports flexible acquisition according to experimental demand. Following established Eggertz design conventions, the tube guarantees reproducible results in quantitative colorimetry and related sample-preparation steps without extraneous features.

Questions about Color comparing tubes, Eggertz, with ST
What is this article?
Color comparing tubes, Eggertz, with ST is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
