Description
Washers for polarimeter tubes, small sample volumes are replacement sealing rings intended for polarimeter tubes designed to handle limited sample quantities. These washers restore a reliable seal on polarimeter cells used in optical rotation measurements, ensuring sample integrity and preventing leakage during analysis of low-volume specimens. Supplied as 1 set, the components address wear of original gaskets in polarimetry workflows common to pharmaceutical, chemical and food laboratories. With a net weight of 0,05 kg and gross weight of 0,1 kg, the set remains compact for convenient storage and handling. Produced by manufacturer Bellingham + Stanley, the washers serve as direct spare parts for polarimeter tubes requiring tight sealing under standard laboratory conditions. They support continued accurate polarimetric determinations where small sample volumes are employed. Originating from China, the set provides a practical maintenance solution for laboratories operating polarimeters and needing to replace worn sealing rings without changing the entire tube assembly.
This article is part of Refractometers & polarimeters, in Spectroscopy & photometry.

Questions about WASHER PACK
What is this article?
WASHER PACK is the article on this page. Luminix Health distributes Bellingham + Stanley for laboratory use. It sits in Refractometers & polarimeters, inside Spectroscopy & photometry, in Lab instruments.
A refractometer reads the refractive index of a liquid, often expressed as Brix for sugar. A polarimeter reads the rotation of polarised light. Both depend on temperature. A handheld refractometer and a thermostated benchtop instrument are different accuracies.
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.
