Ultra-Micro Spectrophotometer (QXM-US097)

A spectrophotometer, also known as a spectrometer, is an instrument for quantitative and qualitative analysis of substances, and is commonly used for nucleic acid and protein quantification and quantification of bacterial growth concentrations.
QXM-US097 is a UV-Vis spectrophotometer dedicated to the micro-volume analysis of purified nucleic acids and a variety of proteins, the use of a minimum volume of up to 0.5 μL of each test sample, the concentration of the samples can be detected than the standard cuvette hundreds of times.

Features

Intelligent Android operating system, 7-inch capacitive touch screen, multi-touch, dedicated APP interface is more intuitive, humanized design;
Cuvette slot, more comfortable for bacteria/microorganisms and other culture fluid concentration detection;；
The instrument does not need to be connected to a computer, and can complete sample testing and data storage alone;
Image and table storage format: table compatible with Excel, convenient for subsequent data processing, support JPG image export;
High-precision linear motor drive, so that the accuracy of the optical range reaches 0.001mm, and the absorbance detection is highly repeatable;
Only 0.5~2μl of sample is needed for each test, and the sample can be recovered after the measurement, so that the study of precious samples can be carried out with confidence;
Spot the sample directly on the spiking platform without dilution, the measurable sample concentration is 50 times of the conventional UV-visible spectrophotometer, the detection and display of results can be completed in 2s~6s, and the results can be directly output as the sample concentration without additional calculation.。
