UV Vis Spectrophotometer

Introduction

A UV-Vis spectrophotometer measures absorbance and transmittance of samples in ultraviolet and visible ranges. It is widely used in chemistry and life sciences. The system ensures accurate optical analysis. It solves limitations of qualitative observation. By providing quantitative spectral data, it supports reliable analysis.

Standards

European Pharmacopoeia 2.2.25-Spectrophotometry, ultraviolet and visible

ASTM E275-08(2022)-Standard Practice for Describing and Measuring Performance of Ultraviolet, Visible, and Near-Infrared Spectrophotometers

USP General Chapter <857>-Ultraviolet-Visible Spectroscopy

Complies with the above standards, but is not limited to them.

Features

1. Diffraction grating or monochromator provides precise wavelength selection.

2. Multiple modes support absorbance, transmittance, concentration and kinetics.

3. Quality optical system delivers accurate wavelength and photometric results.

4. USB, RS232 or printer options export results and reports.

5. Automatic wavelength calibration and self-checks support reliability.

FAQ

What are the main applications of the UV Vis Spectrophotometer?

The UV Vis 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 UV Vis 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?

We provide a 12-month limited warranty on the instrument and its key working parts. Consumables, accessories and parts subject to normal wear are excluded, as is damage caused by incorrect operation or maintenance. An extended service plan is available on request.

Is the UV Vis Spectrophotometer difficult to operate?

The controls are designed for regular laboratory use, so most users become confident after a brief introduction. The manual walks through each step, and common settings can be saved for repeat work. Online or on-site training is available if the site requires it.

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.

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.

Are the consumables universal or proprietary?

The instrument uses standard, widely available consumables rather than special locked items. Replacement parts, accessories and consumables can be ordered from us against the model number. We keep common service parts in stock for prompt supply.

Can it be adapted to our requirements?

Customisation is supported for many installations, including tailored parameters, connections and accessories. Our team reviews the requirement and confirms feasibility and lead time in advance. We avoid committing to options that cannot be delivered reliably.

Do you provide on-site installation?

Standard installation is straightforward and supported by the manual and start-up documentation. Our technical team can guide staff remotely through checks and validation. On-site commissioning is available as a quoted service.

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.
