DOUBLE BEAM UV-VIS Spectrophotometer with more
accuracy and flexible requirements. The two detectors are used to measure
sample and refrence respectively and simultaneously for optimizing
meaaurement accuracy It has vide wavelength range satisfying requirement of
various fields. Such as biochemical research and industry. Pharmaceuticals
analysis and production, education, environment protection. Food industry
etc
SAILENT FEATURES

- Fully automated design, realizing the simplest measurement &satisfying
the requirement of pharmacoppeia.
- Maximum of 9 Wavelength & 8 sample can be measured at one time
- Automatic change-over between W lamp &D2 lamp
- Optimized optics and large scale integrated circuits, light source
and receiver from world famous measurement methods all add up to high
performance and reliability.
- Rich measurement methods wavelength scan, time scan, multi-wavelength
determination multi-order derivative determination, double w-wavelength
method and triple-wavelength methods etc, meet difference measurement.

- Data Output can be optained via a printer port and a USB interface.
- Parametters and data can be saved for user 5 convenience.
- PC controller measurement can be achieved for more accurate and
flexible requirement
Tecnnical Parameters Basic Mode To measure the Absorbance and
transmiitance
Quantitative
- Coefficient Method : Standard Curve Up to 10 Standard sample may be
used to establish a curve. Four method 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 are quickly and easily calculated.
Absorbance ratios 260 nm/280 nm with optional subtracted absorbance at
320 nm. DVA concentration^ 62.9xA260-36.0 x A280 protein concentration^
552xA260-757.3xA280
Wavelength Scan
- The wavelength scan intervals are 0.1,0.2,0.5,1,2,5 nm
- Hi, Medium and low scan speed are available. They vary from 100 to
3600nm/min
- Wavelength are scanned from high to low so that the instrument waits
at high WL. and it minimizes the degradation of UV sensitive sample.
Kinetics
This mode may be used for time course scanning or reaction are
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
interval of 0.5,1, 2,5, 10,30 seconds and one min. Post-run manipulation
includes re-scalling, curve tracking and selection of the part of the curve
required for rate calculation. Rate is calculated using a linear regression
algorithm before multipling be the entered factor.
