Description
Colorimeter cylinder 50 ml Boro 3.3 is a Nessler-type laboratory cylinder designed for reliable visual colorimetric comparisons. The low-form vessel features a fused, optically pure base plate and a permanent graduation mark at 50 ml, enabling consistent matching of sample colour against standards. With a height of 150 mm and a diameter of 26 mm it offers a practical optical path while remaining easy to handle and store on the bench. Manufactured from borosilicate glass 3.3, the cylinder combines chemical resistance with good thermal stability for routine analytical use. The optically clear bottom supports uniform light transmission, which is essential for Nesslerisation and other colour-matching procedures common in water analysis and environmental testing. Supplied as a single piece from manufacturer Witeg, this colorimeter cylinder integrates smoothly into standard laboratory workflows. Its robust construction, precise volume mark and stable low-form geometry help laboratories achieve reproducible visual results across multiple samples. Suitable for research, quality-control and educational settings that rely on Nessler cylinders for semi-quantitative or comparative colorimetry.

Questions about Color comparison tubes 50 ml boro 3.3
What is this article?
Color comparison tubes 50 ml boro 3.3 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Measuring cylinders, inside Volumetric glassware, in Labware.
A measuring cylinder is the tall graduated vessel for a volume that does not need volumetric-flask accuracy. Class A and class B differ in tolerance. Reading the bottom of the meniscus, at eye level, is part of using it.
Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
