UV-Vis-NIR Spectrophotometer

Introduction

UV-Vis-NIR Spectrophotometers offer wide wavelength ranges for advanced optical analysis across a broad spectrum of applications. They have dual detection systems with photomultiplier tubes and lead sulfide detectors. These are equipped with high-quality light sources, ensuring precise optical measurements. They use Analog-to-Digital (AD) signal processing for accurate analysis of sensitive or low-concentration samples. UV-Vis-NIR Spectrophotometers feature advanced software with real-time data display, automating repetitive tasks for precise analysis of optical and electronic properties. Measurement accuracy: ±0.01 pH; range: 0.00 to 14.00 pH.

FAQ

What are the main applications of the UV-Vis-NIR Spectrophotometer?

The UV-Vis-NIR 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.

Which standards and regulations apply to the UV-Vis-NIR Spectrophotometer?

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.

What warranty comes with the UV-Vis-NIR Spectrophotometer?

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 UV-Vis-NIR Spectrophotometer to use?

Routine operation is straightforward and is covered in the user manual, including setup, daily use and basic maintenance. Staff with basic laboratory experience can run it after a short familiarisation. We provide remote guidance and can arrange on-site training where required.

What is the typical lead time for order delivery?

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.

How often should the UV-Vis-NIR Spectrophotometer be calibrated?

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.

Are the consumables universal or proprietary?

Common consumables and standard spare parts are available through our service channel and are not locked to proprietary formats. Quote the model and serial number when ordering so the correct items are supplied. Lead time for standard parts is usually short.

Are options or configurations available?

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.

Is installation and commissioning included?

Most models can be commissioned by following the manual, including positioning, connections, checks and a first test run. Remote guidance is available during start-up. On-site installation, commissioning and training can be arranged separately where required.

What should be avoided when using the UV-Vis-NIR Spectrophotometer?

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.
