NANBEI INSTRUMENTS 190-1100nm 1.8nm Scanning Double-Beam UV-Vis Spectrophotometer
Features
1 High stability: Czerny-Turner type dual-beam optical system is adopted to reduce chromatic aberration and ensure long-term data stability. Instrument drift <0.0008Abs;
2 High precision: The grating is driven by a micrometer-level precision screw rod to ensure that the wavelength accuracy is less than ±0.3nm; the transmittance accuracy is ±0.3%, and the accuracy level reaches: Class I;
3 Easy to use: 5.7-inch large-screen LCD display, the map and curve are clear at a glance, and the operation is simple and convenient. Quantitative, qualitative, kinetic, DNA/RNA, multi-wavelength analysis and other special test procedures;
4 Long service life: original imported Deut lamp and tungsten lamp ensure that the life of the light source is up to 2 years, and the life of the receiver is up to 20 years;
5 A variety of accessories are available: automatic sample sipper, micro cell holder, integrating sphere diffuse reflection, 5° specular reflection and other accessories to meet special application requirements.
Product Features
1 Photometric measurement: It is convenient to measure the absorbance of the sample at the specified wavelength,
Transmittance. Fixed-point test can measure up to 10 wavelengths at the same time;
2 Quantitative measurement: automatic establishment of standard curve, first order\first order zero crossing,
Second-order and third-order curve fitting, single wavelength calibration, dual wavelength calibration, and three-point method are optional; standard curves can be stored and recalled;
3 Qualitative measurement: The scanning speed is 3500nm/min, and there are many spectrum processing methods, including: scaling, smoothing, filtering, peak and valley detection, etc.;
4 Kinetic measurement: Calculation of enzyme kinetic reaction rate. Various map processing methods such as scaling, smoothing, filtering, peak and valley detection, and derivation are available for your choice;
5 DNARNA, protein test function, automatic calculation of sample ratio and concentration.
