|Model No. – WSPECTRO-10001||Make – WESWOX|
Spectrophotometer is double beam optical system can restrain drift, compensates for blank changes, Suitable for long time test. It is simple to fit a curve by using your standard with single or dual WL. It have wavelength scanning function using PC software. It is widely used in colleges and QC labs.
- Double beam optical system.
- Low noise and low stray light.
- Large LCD display, can display curve.
- High quality grating, detector and lamps.
- Data and curve can be stored in real time.
- Auto setting WL, auto blank.
- Lamps can be turned on/off individually.
- Easy to change Pri-aligned lamps.
- Reinforced baseboard and bracket assures durability.
|Basic Mode||To measure the absorbance and transmittance|
|Quantitative||1. Coefficient Method
2. Standard Curve Up Standard may used to establish a curve. Four methods for fitting a curve through the calibration points: Linear fit. Linear fit through zero, Square fit the cubic fit.
|DNA/Protein Test||Concentration and DNA purity are quickly and easily calculated: Absorbance rations: 260nm / 280 nm with optional subtracted absorbance at 320 nm. DNA concentration = 1552xA260-757.3xA 280.|
|Wavelength Scan||1. The wavelength scan intervals are 0.1,0.2,0.5,1,2.5 nm
2. High, Medium and low scan speed are available. They vary from 100 to 3600 nm/min
3. Wavelength are scanned from high to low so that the instrument waits at high WL. And it minimizes the degradation of UV sensitive samples.
|Kinetics||Abs vs time graphs is display 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 second and one min. Post-run manipulation includes re-scalling, curve tracking the selection of the part of the curve required for rate calculation. Rate is calculated using a linear regression algorithm before multiplying be the entered factor.|
