description
Versatile across physics, materials science, chemistry, biochemistry, chemical engineering and molecular biology, this instrument supports critical analytical tasks such as enzyme activity assays, protein concentration quantification, enzymatic kinetic constant determination, and ligand binding reaction measurements.
features
1. Superior Precision: A micrometer-grade precision lead screw drives the grating, delivering a wavelength accuracy of <±0.3nm and transmittance accuracy of ±0.3%T, meeting Class I performance standards
2. Exceptional Stability: Equipped with a Czerny-Turner dual-beam optical system, the instrument minimizes chromatic aberration and guarantees sustained data stability over prolonged use
3. User-Friendly Operation: Features a 5.7-inch large-screen LCD display for clear visualization of graphs and curves, with intuitive access to specialized test procedures including quantitative, qualitative, dynamic, DNA/RNA and multi-wavelength analysis
4. Extended Service Life: Incorporates original imported xenon and tungsten lamps with a 2-year lifespan, paired with a receiver that offers an operational life of up to 20 years
5. Versatile Accessory Compatibility: Supports a range of optional accessories including automatic samplers, micro cell holders, integrated sphere diffuse reflectance modules and 5° specular reflectance components to meet specialized testing requirements
Function:
1. Quantitative Measurement: Automatically generates standard curves, supporting first-order, first-order zero-crossing, second-order and third-order curve fitting models
2. Photometric Measurement: Enables convenient testing of sample absorbance and transmittance at designated wavelengths, with fixed-point testing capable of analyzing up to 10 wavelengths simultaneously
3. Qualitative Measurement: Boasts a scanning speed of 3500nm/min, with integrated map processing functions including scaling, smoothing, filtering and peak-valley detection
4. Kinetic Measurement: Facilitates calculation of enzyme kinetic reaction rates, paired with data processing tools such as scaling, smoothing, filtering, peak-valley detection and derivation
5. DNA/RNA & Protein Testing: Automatically calculates sample ratios and concentrations for streamlined nucleic acid and protein analysis
