Double Beam Spectrophotometer Feature And Application

1. Independent double optical path and double beam optical system;

2. Can independently complete photometric measurement, quantitative measurement, spectral scanning, kinetics, DNA/ protein testing functions.

3. Suspension type optical system design, strengthen the design of thickened bottom plate, eliminate the impact of vibration or deformation on the optical system.

4. The software is fully compliant with 21CFR Part 11, audit trail, pharmacopoeia and electronic signature.

5. Large screen dot matrix liquid crystal, clear map data display, friendly interface, easy to operate.

6. Smaller spectral bandwidth, higher resolution, fully meet the requirements of the pharmacopoeia, wider application range.

7. Long life environment-friendly deuterium lamp with flange seat, light replacement is free of optical debugging.

8. The graph and data can be saved in real time and can be maintained when power is off. It can be printed and exported to PC.
