FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The single-beam UV-visible spectrophotometer is used in teaching laboratories, routine quality control, food and beverage testing, environmental analysis and basic research for quantitative absorbance measurement in the ultraviolet and visible ranges. It supports concentration determination by Beer-Lambert law, protein and nucleic acid quantitation, enzyme activity measurement, water quality parameter testing, color analysis and general chemical analysis. The single-beam design provides a cost-effective solution for routine fixed-wavelength measurements where the advanced features of double-beam instruments are not required. It is ideal for educational institutions, small quality control laboratories and facilities requiring reliable absorbance measurement for standard analytical methods without the complexity or cost of scanning or double-beam systems.
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. Proper wavelength setting, blank correction and sample handling are important for accurate results. Single-beam instruments require manual baseline correction when changing wavelength or lamp.
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 is recommended every 6-12 months. Lamp replacement should follow the manufacturer schedule or when intensity drops. Routine verification 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, with lamp replacement being the main recurring item.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes wavelength range, software features and sample compartment accessories. Additional cuvettes, sippers and standards 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 samples cause scattering errors. Highly corrosive samples require compatible cuvette material. Very concentrated samples should be diluted to the linear range. Users should perform proper blank correction and allow lamp warm-up before measurement for stable results.
