Measuring the amount of light of a specified wavelength which passes through a medium or the amount of light absorbed by a solution, spectrophotometers are an essential instrument in biology, chemistry, medical and forensic laboratories. Feature-wise, it’s important to look for ease of use, clear display, high reproducibility, and affordability when investing in this piece of lab equipment.
When purchasing the instrument for a school lab, make sure it comes with all the features essential to teach the subject of spectroscopy. Large, easy-to-read, high resolution display is a useful property when it comes to industrial quality control, water analysis, and educational purposes.
A leading manufacturer of medical laboratory equipment, UNICO offers several high quality spectrophotometer models such as S-1000, S-1100, S-1200, and SQ-2802. The UNICO SQ-2802 series features an advanced single beam design consisting of four models, two stand-alone models and two PC models with Windows based application software. The instruments feature:
