Micro-Volume UVVIS Spectrophotometer BK-CW500

Micro-Volume UVVIS Spectrophotometer BK-CW500 Features: 1. The uniquely designed sample holder can test a small amount of DNA and protein. 2. Detection is rapid, drop sample-rotation-detection. 3. The whole measurement process without light loss, to ensure the accuracy of the results. 4. The function can be expanded, and can complete quantitative testing, wavelength scanning, kinetics, multi-wavelength and other functions,and can also be used for conventional colorimetric blood measurement.
