FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The touch screen UV-visible spectrophotometer is used in pharmaceutical, chemical, environmental, food and quality control laboratories for quantitative analysis by absorbance measurement. It supports drug content assay, impurity testing, protein quantitation, water quality analysis, color measurement and general chemical testing. The touch screen interface simplifies operation for routine users, allowing direct method selection, calibration curve setup and result review without external computer. It is particularly suitable for quality control environments where multiple operators use the instrument and ease of use is important.
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. The hardware complies with IEC 61010 laboratory safety standards. Wavelength and absorbance accuracy should be verified with certified reference materials.
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, touch screen 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: The touch screen interface makes operation intuitive for routine users. Basic training in spectrophotometry and method setup is recommended. We provide an operation manual and remote guidance. Built-in method templates reduce the need for extensive programming knowledge.
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. Routine verification before each batch is recommended for regulated work. Touch screen calibration is generally not required but should be checked if response becomes inaccurate.
Q7: Are supporting consumables universal?
A: Lamps, cuvettes and calibration standards are available from multiple qualified suppliers. Long-term consumable cost is moderate.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes wavelength range, software methods and 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 samples require pretreatment. Highly corrosive samples require compatible cuvettes. Very concentrated samples should be diluted to the linear range.
