Double Beam UV/Visible Spectrophotometer

Introduction

Double Beam UV/Visible Spectrophotometer provides absorbance and transmittance measurements across a wide spectral range. They have dual beams that work together to measure samples and references, increasing stability and precision. It ensures a reliable and easy setup Features of low noise and stray light, a large LCD, and high-quality components. Double Beam UV/Visible Spectrophotometers are suitable for applications such as quantitative analysis, and DNA/protein analysis, pharmaceutical and biochemical clinical lab applications.

FAQ

What is the Double Beam UV/Visible Spectrophotometer mainly used for?

The Double 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 Double 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.

What warranty comes with the Double Beam UV/Visible 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.

Is the Double Beam UV/Visible Spectrophotometer difficult to operate?

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.

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 Double Beam UV/Visible Spectrophotometer be calibrated?

Regular calibration keeps measurements within the stated accuracy; an annual check is typical, with shorter intervals for heavy or regulated use. Reference standards and procedures are described in the manual. We can quote calibration with certificates.

Are consumables and spare parts easy to obtain?

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?

The standard model can be configured with selected accessories and operating options to suit the task. Non-standard requests are assessed before quotation so the final build is clearly defined. We confirm details before production.

How is the Double Beam UV/Visible Spectrophotometer commissioned?

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 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.
