UV/VIS Spectrophotometer
UV-Vis spectrophotometers provide fast and efficient analysis, allowing researchers to obtain results within a few seconds.
It is used to quantify:
- Â nucleic acid
- protein content in biological samples
- for quality control in drugs and food industries.
Lead Time: 3-4 Weeks
The S-20 and S-22 are high quality, low cost measurement systems for routine analysis in QC applications, education and training.
