Introduction
A UV-visible spectrophotometer is an analytical instrument used to measure the absorption, the transmittance, and the reflectance of the light by the samples over the ultraviolet and the visible wavelength regions, and it is used in the chemistry, the biology, the clinical, the pharmaceutical, the food, and the many other laboratories. The UV-visible spectrophotometer measures the absorbance of the light by the sample over the wavelength range, typically from about 190 to 1100 nanometers, and the absorbance is related to the concentration of the absorbing species by the Beer-Lambert law; the UV-visible spectrophotometer consists of a light source, a monochromator, a sample holder, a detector, and a control and a display unit, and it provides features such as the wavelength scanning, the absorbance and the transmittance measurement, and the standard curve analysis; the UV-visible spectrophotometer is used for the quantitative and the qualitative analysis, for the measurement of the concentration of the samples, for the analysis of the nucleic acids and the proteins, for the analysis of the dyes and the colored solutions, for the quality control, for the clinical analysis, for the food analysis, and for many other applications, and it is available as the benchtop and the portable instruments; the UV-visible spectrophotometer is an essential instrument for the analytical chemistry. UV-visible spectrophotometers are used in the chemistry and the biology laboratories, in the clinical laboratories, in the pharmaceutical industry, in the food industry, in the environmental monitoring, and for many other applications. With their UV-visible measurement, UV-visible spectrophotometers are essential for the quantitative analysis.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The UV-visible spectrophotometer is used in pharmaceutical, chemical, environmental, food and educational laboratories for quantitative analysis by measuring absorbance at specific wavelengths. It supports drug content determination, impurity testing, protein and nucleic acid quantitation, water quality parameter measurement, color analysis and general chemical analysis. The instrument is a workhorse for routine quality control and teaching laboratories where reliable absorbance measurement is required without the advanced scanning or automation features of higher-end models.
Q2: What standards does the instrument comply with?
A: The instrument supports analytical methods referenced in USP, EP and ChP monographs, ASTM E169 for UV-Vis quantitative analysis, and relevant GB/T standards for spectrophotometry. The hardware complies with IEC 61010 laboratory safety standards. Wavelength and absorbance accuracy should be verified with certified reference materials for regulated applications.
Q3: What is the warranty period for the whole machine and key components?
A: The whole spectrophotometer is covered by a 12-month warranty. The optical system, detector, light source and controller are covered, while lamps, cuvettes and calibration standards are consumables excluded from warranty.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic laboratory training in spectrophotometry. We provide an operation manual and remote guidance. Routine fixed-wavelength measurement can be performed by trained operators after familiarization with wavelength setting, blank correction and sample handling.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Wavelength and absorbance calibration with certified reference materials should be performed every 6-12 months for accredited laboratories. Routine verification with a reference standard before each batch is recommended for regulated work.
Q7: Are supporting consumables universal?
A: Lamps, cuvettes and calibration standards are available from multiple qualified suppliers. Long-term consumable cost is moderate. The deuterium and tungsten lamps have finite service lives and are the main replacement items.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes wavelength range, software features and sample compartment accessories. Additional accessories such as sippers and temperature controllers can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the spectrophotometer and accessories with an operation manual. Remote commissioning guidance is provided. On-site service is not included for standard orders.
Q10: What types of samples are compatible with this equipment?
A: The instrument analyzes liquid samples within the wavelength and absorbance range. Samples must be clear and homogeneous. Turbid or particulate samples may cause scattering errors and require filtration or centrifugation. Highly corrosive samples require compatible cuvette material. Very concentrated samples should be diluted to the linear range.
