Description
Colorimeter tube according to Eggertz 30:0,1 ml with NS stopper is precision laboratory glassware for colorimetric analysis and visual colour comparison. It features a clear graduation scale of 30:0,1 ml together with an NS 12/21 ground joint and matching NS stopper for secure closure during sample handling. Supplied as 1 pc, the tube supports accurate volume measurement and standardised colour matching in analytical workflows. Produced by manufacturer Witeg in Germany (Baden-Württemberg), this Eggertz-style colorimeter tube belongs to the family of Nessler-type tubes used for turbidity and colour intensity assessments. The fine 0,1 ml divisions up to 30 ml enable reliable preparation and reading of solutions under controlled conditions. The NS 12/21 joint ensures compatibility with common laboratory stoppers and accessories, while the robust glass construction provides good visibility and durability for routine use. Ideal for research, quality-control and teaching laboratories that require reproducible colorimetric results, the single-piece unit allows flexible procurement. Its design follows established Eggertz conventions, delivering consistent performance for quantitative colour evaluations without unnecessary complexity.

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.
