● Instrument host with USB2.0 data export function, support USB printer PCL Class A4 paper

● Import environmentally friendly deuterium lamp system can effectively reduce your intake of ozone

● Advanced and reasonable optical system design and 1,200 / mm holographic gratings are guaranteed to achieve ultra-low stray light

● Advanced control system for deuterium lamp, tungsten lamp life time monitoring

● Unique socket design deuterium and tungsten lamps, lamp replacement is free optics debugging

● GLP self-identification function, testing instruments wavelength accuracy and photometric accuracy, and issue the test reports and power protection

● The instrument can be automatic wavelength calibration, automatic wavelength setting, automatic switching light and dark current correction

● Fully sealed structure and all optical mirror with Si02 protective film, an overall reduction in optical components by the external gas and environmental impacts

● PC software can be achieved through the full wavelength scan, quantitative measurement, multi-wavelength testing, kinetics, DNA / protein measurements

1 Photometry

Measured at a given wavelength absorbance of the sample, and the energy transmittance

2 Quantitative measurement

A first-order through zero and first-order two kinds of fitting manner

Coefficient method, standard input, standard read three ways to establish a standard curve

Establish A = K1 * C + K0, you can find the original data, maps curve, set the parameters. Save 240 set of curves, each curve can test 240 data

3 Multi-wavelength

Up to eight different wavelengths can test the transmittance and absorbance of the sample

4 Kinetic

Fixed wavelength points tested over a period of time, the sample absorbance or transmittance

Change maps, calculate sample response rate △ A / t scan time. Sampling interval, delay time, wavelength point can be set according to actual needs

5 Optic Scan

In the 190-1100nm range, according to test requirements set the scan interval. Maximum absorption peak of the sample is measured, the derivative can be the pattern, math and other data processing

6 Biological

Methods: DNA / protein quantitative determination, UV, Lowry, BCA, CBB, Biuret
