V-1800 visible spectrophotometer Introduction
Visible spectrophotometer V-1800, the instrument built-in microcomputer, realizes man-machine dialogue, simple operation, perfect function, can be widely used in petroleum, chemical, pharmaceutical, environmental protection, teaching, materials science and other fields, is scientific research, production, teaching Indispensable analytical test instrument
Feature
●The instrument can perform automatic wavelength correction, automatic wavelength setting, automatic switching of light source and dark current correction
●Large sample room, can accommodate 5-100mm cuvettes of various specifications and various accessories (automatic eight-frame, micro cuvette holder, etc.), greatly improving test efficiency
● 1200 strips / mm holographic grating and fully sealed structure to ensure that the instrument has excellent performance indicators and ultra-low stray light, reducing the overall impact of optical components on the external gas and the environment
● PC scanning type, software functions include: photometric measurement, quantitative measurement (including standard curve function), wavelength scanning, multi-wavelength test, DNA/protein and nucleic acid test, etc.
● Directly connect to the printer (optional), print maps and experimental data. Main functions
●Photometric measurement The absorbance, transmittance and energy of the sample measured at a constant wavelength
●Quantitative test Standard curve method: Zui can establish a standard curve of 9 points, display map and regression equation. Coefficient method: use the formula C=KA B or A=KC B to measure by input correlation coefficient
● Kinetic test Test the change spectrum of absorbance or transmittance of the sample to be tested at a fixed wavelength point, calculate the reaction rate of the sample? A/t, scan time, sampling interval, wavelength point, set according to actual needs.
