FAQ

What is the Single Beam UV-Visible Spectrophotometer mainly used for?

The Single Beam UV-Visible Spectrophotometer is used to measure absorbance, transmittance or concentration of samples across a defined wavelength range. It supports quantitative analysis, purity checks, kinetics and quality control in chemistry, biology, pharmaceutical and environmental laboratories.

What standards does the Single Beam UV-Visible Spectrophotometer comply with?

The instrument is designed with reference to IEC 61010 electrical safety requirements and relevant GB/T standards for spectrophotometers, including wavelength and photometric accuracy. Procedures should follow applicable standard methods. Compliance documentation can be provided on request.

How long is the warranty period?

The system is covered for 12 months after shipment, including the main mechanism and electrical controls. Replaceable consumables and routine service items are not part of the warranty. Faults caused by improper installation outside the manual or unauthorised modification are not covered.

How easy is the Single Beam UV-Visible Spectrophotometer to use?

No advanced specialist skills are needed for standard operation, though correct sample handling and safety practice should be followed. We supply a detailed manual and start-up support. For multi-user or regulated sites, a short staff training session can be arranged.

How long does delivery usually take?

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.

Is calibration included?

The unit is calibrated and tested before delivery. For ongoing accuracy, verify it against traceable reference standards every 6 to 12 months, or according to the laboratory quality schedule. We can arrange calibration service and certificates where required.

Where do we get replacement parts?

Filters, seals, probes and similar items are standard and can be supplied through our channel. Customers may also source equivalent items that meet the specification. Provide the model and serial number to confirm compatibility before ordering.

Can the Single Beam UV-Visible Spectrophotometer be customised?

Yes, common options include different ranges, voltages, accessories, interfaces and capacity or size configurations. We confirm feasibility, specifications and any delivery impact before order confirmation. Custom requirements are reviewed case by case.

Do you provide on-site installation?

Benchtop and standard units typically require only placement and connection before use, while larger systems may need professional commissioning. We confirm the installation requirements at order stage. On-site service and training can be provided if needed.

What maintenance and safety points matter?

Do not measure highly corrosive or incompatible samples, use dirty cuvettes or skip blank correction. Verify wavelength and photometric accuracy periodically. Follow laboratory safety rules.
