190-1100mm uv visible spectrophotometer (1200 Lines/mm Grating)
Application:
UV8 Series are advanced double beam design consisting of 3 models: UV8000, UV8000A, UV8000S. All the 3 models are Standalone models: UV8000 with 1.8nm fixed bandwidth, UV8000A with 1nm bandwidth and UV8000S with 0.5/1.0/2.0/4.0nm variable bandwidth. Except bandwidth, other specifications of the 3 models are almost the same.
The two detectors are measuring sample and reference respectively simultaneously for optimizing measurement accuracy.
Functions:
All software methods are included as builtin standard, thus eliminating the need for software options. Online software upgrade via Internet helps to keep your software up-to-date.
The local control software include functions as: Basic Mode, Quantitative, Wavelength Scan, Kinetics, DNA/Protein, Multi- wavelength Test and System Utilities.
Standard Curve
Up to 10 standard solutions may be used to establish calibration equation curve. There is a choice of four methods for fitting a curve through the calibration points: Linear fit, Linear fit through zero, square fit and cubic fit.
Wavelength Scan
The wavelength scan intervals are 0.1, 0.2, 0.5, 1, 2, 5nm, and Hi, Medium and Low scan speeds are available. Scan speeds vary from 100 to 1000nm/min. Wavelengths are scanned from high to low so that the instrument waits at high wavelength. This minimizes the degradation of UV sensitive samples. Precise control of filter and lamp changes means that their effects are not seen on the final scan. Post-run manipulation includes re-scaling axes, curve tracking and peak picking.
Kinetics
1This mode may be used for time course scanning or reaction rate calculations. Abs. vs. time graphs is displayed on the screen in real time.
2Wait 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.
3Postrun manipulation includes rescaling, 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.
Multi-Wavelength
Up to 10 wavelengths may be entered, allowing the measurement of multiple wavelengths on a series of Samples
DNA/Protein Test
Concentration and DNA purity are calculated:
Absorbance ratios 260nm/280nm or 260nm/230nm with optional subtracted absorbance at 320nm
DNA Concentration=62.9 x A260 - 36.0 x A280
or 49.1x A260 - 3.48x A230
Protein Concentration=1552 x A260 - 757.3 x A280
or 183 x A260 - 75.8 x A230
Other wavelengths and factors may be entered.
