Description
Quartz control plate 50 is a reference standard providing 50 °Z (17 °A) optical rotation at 589 nm and 850 nm, measured at 20 °C and accompanied by a certificate of conformity. Designed for straightforward verification of polarimeters and saccharimeters, the plate enables laboratories to confirm instrument accuracy on both the International Sugar Scale and angular scale without complex preparation. Supplied as a single piece with a net weight of 0,72 kg and gross weight of 0,8 kg, it is compact and ready for immediate use in routine quality checks. This control plate from manufacturer Bellingham + Stanley offers stable, reproducible readings that support consistent performance monitoring in food, beverage, pharmaceutical and research laboratories. Its dual-wavelength specification at a defined temperature simplifies compliance with internal quality procedures and instrument maintenance schedules.

Questions about QUARTZ CONTROL PLATE 50
What is this article?
QUARTZ CONTROL PLATE 50 is the article on this page. Luminix Health distributes Bellingham + Stanley for laboratory use. It sits in Lamps, cuvette holders & accessories, inside Spectroscopy & photometry, in Lab instruments.
A spectrophotometer's lamp, deuterium for UV and tungsten for visible, is a consumable with a life in hours. A cuvette holder sets the path. A 10 mm holder does not correctly read a 1 mm cell unless the software is told. The accessory has to fit that optical bench.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
