Microprocessor UV-Vis Spectrophotometer(Double Beam) For Electrical Lab Training

CAT NO: DIDACTICNLE-Export-013028

Description & Specification:

Microprocessor UV-Vis Spectrophotometer(Double Beam) For Electrical Lab Training Workshop.
Technical Specifications Display Graphic LCD (320*240 Dots) Lamps Deuterium Lamp & Tungsten Halogen Lamp Detector Silicon Photodiode Dimensions(L*W*H) 630 x 430 x 206 mm Net Weight 26 Kg To measure the Absorbance and Transmittance Quantitative 1.   Coefficient Method 2.   Standard Curve  Up to 10 standard 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. DNA/Protein Test Concentration and DNA purity and easily calculated:-Absorbance ratios 260 nm / 280 nm with optional subtracted absorbance at 320 nm. DNA concentration=62.9xA260-36.0 x A2B0 Protein concentration=1552xA260-757xA280. Wavelength Scan 1.     The wavelength scan intervals are 0.1, 0.2, 0.5, 1, 2, 5 nm 2.     High, Medium and Low scan speeds are available. They vary from 100 to 3600 nm/min. 3.     Wavelengths are scanned from high to low so that the instrument waits at high WL and it minimize the degradation of UV sensitive samples. Kinetics This mode may be used for time course scanning or reaction rate calculations. Abs vs time graphs is displayed on the screen in real time. Wait time and measurement time up to 12 hours may be entered with time intervals of 0.5,1,2,5,10,30 seconds and 1 min. Post-run manipulation includes re-scaling, curve tracking and selection of the part of the curve required for the rate calculation. Rate is calculated using a linear regression algorithm before multiplying by the entered factor.
