Description
Ring made of Duran for round glasses type 202 is a precision glass accessory designed for Hellma® spectroscopic and laboratory glassware. Manufactured entirely in Germany, the ring benefits from the high dimensional accuracy that characterises Hellma glass products and supports continuously reproducible measurement results. Chamfered edges ensure safe, comfortable handling and reduce the risk of chipping during assembly or cleaning. The component can be cleaned and reused repeatedly, offering a durable and environmentally responsible alternative to disposable parts. Produced under certified quality and environmental management systems (EN ISO 9001 / EN ISO 14001), the ring meets demanding optical and mechanical standards required in analytical laboratories. With a gross weight of only 0,04 kg it remains lightweight yet robust for everyday use with type-202 round cells. Suitable for laboratories that rely on Hellma round-glass systems and need reliable, long-lasting mounting rings that maintain optical performance over many cleaning cycles.

What is this article?
ring made of duran for round glasses type 202 Hellma® glass products are is the article on this page. Luminix Health distributes Hellma (IDL) 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.
