System functions

◆Storage function: The host can directly store test data, standard curves, graphs, etc., which can be called at any time according to the name, and can be powered off to maintain; Storing data, curves, and graphs can be directly opened, read, edited, printed, etc. on the PC client

Printing function: It can directly connect to a printer to print test data, curves, and graphs

◆ Online function: Using a USB data port, online operations can be easily achieved through software

Self check function: Power on self-test of key parameters and main components, and can recalibrate the system to ensure that the instrument always operates under normal system configuration

Self calibration function: The instrument has wavelength calibration and dark current calibration functions, which can eliminate deviations caused by long-term use and ensure the accuracy of instrument measurements

Other system functions: wavelength positioning, printer settings, light source switch, automatic light source switching settings, light source time recording, time settings, wavelength verification, photometric verification, buzzer switch, factory reset settings, etc

Test function

Basic functions: Measurement functions for transmittance, absorbance, concentration, energy, etc. Single point method for testing sample concentration, multiple concentration units can be selected, and concentration units can be customized

Standard curve: A standard curve can be established through single point sampling or multi-point sampling, and the concentration of the sample can be measured using the newly created standard curve. You can choose from first-order linear zero crossing fitting, first-order linear fitting, second-order fitting, third-order fitting methods, and three calibration methods (single wavelength method, equal absorption point dual wavelength method, and three-point method)

◆ Coefficient method: Sample concentration can be determined by directly inputting the coefficients of the curve equation. Standard curves, standard sample parameters, measurement time, and other information can be stored and printed for easy archiving and retrieval

Spectral scanning: Scanning intervals are available in six levels: 0.1nm, 0.2nm, 0.5nm, 1.0nm, 2.0nm, and 5.0nm; There are three scanning speedsGear selection, high, medium, and low speeds; Scan from high wavelength to low wavelength, and after the scan is completed, the instrument returns to high wavelength to reduce the impact on UV sensitive samples; The graph can be enlarged, reduced, smoothed, and processed accordingly; Can print and retrieve peak values, and store and call graphs

◆Dynamics testing: Time scan of the sample at a fixed wavelength and calculation of reaction rate (Δ A/min). Delay time, running time, sampling time interval, etc. can be set, with sampling time intervals of 0.5s, 1.0s, 2.0s, 5.0s, 10s, 30s, and 1min, and testing time up to 9 hours

◆Multi wavelength testing: It can test the absorbance and transmittance values of a test sample at multiple wavelength points. Up to 10 different wavelengths can be set, and the test results can be stored and retrieved

DNA/protein testing: used for quantitative analysis of DNA and proteins, as well as rapid purity testing, which can directly display concentration and ratio;
