FAQ

Q1: What is the UV-VIS NIR spectrophotometer mainly used for?

A: It is used to measure absorbance, reflectance and transmittance of materials across UV, visible and near-infrared wavelengths. Applications include quantitative analysis, optical material characterisation, pharmaceutical testing, coatings and quality control.

Q2: What standards does the spectrophotometer comply with?

A: The instrument follows applicable ISO and GB/T standards for spectrophotometric analysis, including wavelength and photometric accuracy requirements. Measurement procedures should follow the applicable standard methods. Compliance documentation can be provided on request.

Q3: What is the warranty period for the spectrophotometer and key components?

A: The complete unit carries a 12-month warranty covering the optical system, electronics and controller. Lamps, cuvettes and accessories are excluded as consumables. Damage from improper handling or unauthorised repair is not covered.

Q4: Is the spectrophotometer difficult to operate?

A: Operation requires training in spectrophotometry, sample preparation and software use. The manual explains measurement, calibration and maintenance, and remote guidance is available. Proper baseline correction and sample handling are important for accurate results.

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: Does the spectrophotometer require calibration or verification?

A: Wavelength and photometric accuracy should be verified periodically using calibrated reference standards, typically every 6 to 12 months. The unit is factory calibrated before delivery. Optional calibration service can be arranged.

Q7: Are consumables or spare parts universal?

A: Lamps, cuvettes and standard spare parts are available through our channel. No proprietary consumables are required. Provide the model and serial number when ordering.

Q8: Can the spectrophotometer be customised?

A: Yes, options include different accessories, software modules, sample holders and data interfaces. We confirm each option before order confirmation.

Q9: Is installation and commissioning included?

A: The unit is commissioned by following the manual, including electrical checks, software installation and a performance test. Remote guidance is available during commissioning. On-site installation and training can be arranged.

Q10: What samples should not be measured in this spectrophotometer?

A: Highly corrosive, volatile or radioactive samples require special handling and compatible accessories. Very turbid or concentrated samples may need preparation before measurement. Follow laboratory safety regulations.
