UV-9000 Double Beam UV Visible Spectrophotometer with Long Optical Path

Product Overview

The double beam uv visible spectrophotometer is a high-performance laboratory instrument designed for accurate and stable UV-Visible spectrophotometric analysis. With a double beam optical system, 520 mm long optical path, rigid optical structure, and automatic calibration function, it provides reliable measurement performance for routine and advanced laboratory testing.

Available in UV-9000, UV-9000A, and UV-9000S configurations, the instrument covers a wavelength range of 190–1100 nm and supports spectrum scanning, standard curve analysis, kinetics, multi-wavelength measurement, and DNA/protein testing. Its stand-alone operating system allows users to perform key analysis functions directly from the instrument without relying on a PC.

Key Features

Double Beam Optical System

The double beam optical design helps reduce the influence of circuit fluctuations and stray light, improving measurement stability and repeatability. It is suitable for laboratories requiring consistent UV-Visible analysis over extended operating periods.

Powerful Stand-Alone Operation

The built-in operating system allows users to perform spectrum scanning, standard curve analysis, kinetics, multi-wavelength measurements, and DNA/protein testing directly on the instrument. This provides greater flexibility for routine laboratory analysis.

520 mm Long Optical Path

The unique 520 mm long optical path improves wavelength resolution and contributes to more precise spectral analysis. It is particularly useful when accurate identification and measurement of absorption peaks are required.

Rigid Optical Structure

All major optical components are mounted on a rigid 16 mm-thick die-cast aluminum optical base. This robust construction helps minimize mechanical movement and maintains optical alignment for reliable long-term operation.

One-Button Automatic Calibration

The automatic calibration function simplifies instrument maintenance. With one button, users can perform baseline, wavelength, and dark-current calibration, helping maintain stable measurement conditions and reduce manual adjustment requirements.

6-Inch High-Definition LCD Display

The large LCD display provides a clear interface for viewing measurement data, spectral curves, and operating information directly on the instrument. This makes routine testing convenient even without a connected computer.

USB and Parallel Data Output

The instrument is equipped with USB and parallel ports for convenient data management. The USB connection allows the spectrophotometer to communicate with a computer through the supplied PC software, while the parallel port can be connected to an optional micro thermal printer for direct data printing.

Professional PC Software

The standard PC software provides comprehensive analytical functions, including spectrum scanning, standard curve creation, kinetics analysis, multi-wavelength scanning, and DNA/protein testing. Users can transfer measurement data to a computer for further analysis, storage, and reporting.
