Spectrophotometer Ultraviolet-Visible Double Beam
Spectrophotometer UV/VIS Double Beam Model UV6900
Spectrophotometer belonging to a new generation of dual-beam instruments with 2 detectors that simultaneously measure the reference and the sample to optimize accuracy, sensitivity, low stray light and a bandwidth of up to 0,5 nm.
A suitable instrument for clinical, pharmaceutical and biochemical laboratories as well as current applications and quantitative analysis, kinetics, scannings at various wavelengths and analysis of DNA / Protein. All operable directly on the instrument and displayed on the LCD display or transferred to PC, data, and curve.
♦ Auto - calibration baseline, wavelength and dark current
♦ Equipped with parallel printer port and one USB for PC. Included software
♦ Available a variety of accessories to complete the versatility of the spectrophotometer.
♦ New layout monochromator diffraction grating with 1200 lines which ensures high durability and stability of the system
♦ Software Update by internet

SOFTWARE UV/VIS ANALYST (included). Features
Multi - Wavelength
Up 32 wavelengths can be selected and multiple samples can be measured
Quantitative
1- Coefficient method
2- Standard curve
Up to 10 standards samples may be used to establish a curve. Four methods for fitting a curve through the calibration points: Linear fit, Linear fit through zero, Square fit and Cubic fit
Wavelength Scan
1- The wavelength scan intervals are:0,1-0,2-0,5-1,0-2,0-5,0
2- Scan speed: High - Medium and Low, from 100 to 3000nm/min.
DNA /Protein Test
Concentration and DNA purity are quickly and easily calculated:
Absorbance ratios 260nm / 280nm with optional subtracted absorbance at 320nm
DNA concentration = 62,9 x A260 - 36,0 x A280
Protein concentration= 1552 x A260 - 757,3 x A280
Kinetics
Calculate reaction rates. Graphical time / real time absorbance
Total time up to 12 hours with reading selectable interval 0,5 -1 - 2 - 5 - 10 - 30 seconds and 1 minute
Further manipulation with re-scaling, curve tracking and selection of the part of the curve required for the rate calculation
The speed is calculated using a linear regression algorithm before multiplying by the factor entered
