FAQ

Q1: What is the diffraction grating spectrophotometer mainly used for?

A: It is used to measure absorbance, transmittance and concentration of samples in chemistry, biology, pharmaceutical and quality control laboratories. Typical applications include quantitative analysis, purity assessment and reaction monitoring across the UV-visible range.

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 basic training in spectrophotometry, sample preparation and software use. The manual explains measurement, calibration and maintenance, and remote guidance is available. Proper blank correction and cuvette handling are important for accuracy.

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 wavelength ranges, accessories, software modules 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 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 cuvettes. Very concentrated or turbid samples may need dilution before measurement. Follow laboratory safety regulations.
