Description
Diiodomethane standard liquid ORA-A1007 is a refractometer reference fluid supplied with a content of 2 ml and a stated refractive index of 1,74 nD. The material is identified by CAS number 75-11-6 and is designated as a diiodomethane standard for optical measurement tasks. Packaged as one piece, the small volume is practical for prism-based refractive-index checks and related laboratory procedures. This standard from manufacturer Kern is intended for use with refractometers in quality-control, research and routine laboratory practice. Net weight is 0,10 kg and gross weight 0,20 kg, yielding a compact unit that stores conveniently with other calibration accessories. Clear ORA-A1007 identification supports traceability across multi-instrument setups and method documentation. Laboratories can incorporate the fluid into established verification sequences wherever a high refractive-index diiodomethane standard is specified. Handle according to your laboratory’s chemical hygiene rules and dispose of residual material in line with local regulations and site procedures.

Questions about Liquid KERN ORA-A1007
What is this article?
Liquid KERN ORA-A1007 is the article on this page. Luminix Health distributes KERN 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.
