Description
Air filter T/M is a dedicated replacement filter intended for RFM300-T, RFM900-T and RFM300-M refractometers. Supplied in a convenient pack of 12 pieces, the filter protects the optical and electronic assemblies of these precision instruments from dust and airborne particulates that can accumulate during continuous laboratory operation. Designed for routine maintenance of digital refractometers, it supports stable measurement performance in quality-control, research and process-monitoring environments. The air filter T/M from manufacturer Bellingham + Stanley fits the specified RFM-T and RFM-M series models directly, allowing quick exchange without tools or instrument recalibration. Compact packaging with a net weight of 0,018 kg and gross weight of 0,02 kg keeps storage requirements minimal while ensuring an adequate stock of spare filters is always on hand. Laboratories working with sugar, beverage, chemical or pharmaceutical samples benefit from regular filter replacement to maintain clean airflow and long-term instrument reliability. This accessory forms an essential part of the preventive-maintenance programme for high-accuracy refractometry workstations.

Questions about PACK OF 12 FILTERS
What is this article?
PACK OF 12 FILTERS 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.
