UV-Vis, multi-wavelength and portable spectrophotometers for pharmaceutical QC, clinical and research laboratories. For laboratory equipment distributors, hospital laboratories and quality control buyers.

Product Description:

A spectrophotometer measures how much light a sample absorbs or transmits at chosen wavelengths. UV-Vis instruments typically cover about 190 to 1100 nm, using a deuterium and tungsten-halogen lamp pair or a xenon flash lamp. Single-beam designs are simpler, while double-beam designs measure sample and reference together for a steadier baseline. Array-detector and multi-wavelength models read many wavelengths at once. Portable units suit field and water testing, and microvolume models read nucleic acids and proteins from a drop.

Laboratories use them for assays, identity and purity tests, dissolution testing, kinetics and colorimetric methods. In pharmaceutical quality control the instrument must meet USP <857> and Ph. Eur. 2.2.25 for wavelength accuracy, photometric accuracy, stray light and resolution, checked with certified reference filters or solutions. Clinical chemistry methods often run inside dedicated analysers. Software matters as much as optics: regulated labs need audit trails, access control and electronic records meeting 21 CFR Part 11 and EU GMP Annex 11.

Sourcing notes. A general laboratory spectrophotometer is not normally a medical device. It becomes an in vitro diagnostic device only when the maker intends it for diagnostic examination, and IVD registration then applies. Ask for electrical safety and EMC declarations, typically to IEC 61010-1 and IEC 61326-1, the maker's ISO 9001 or ISO 13485 certificate, and a calibration certificate. GMP labs should request IQ/OQ documents and a performance verification protocol. Check mains voltage, spare lamps, local service and warranty. Specify wavelength range, bandwidth, beam design, software and accessories.
