Description
Product Overview
The UV Visible Spectrophotometer is designed for accurate absorbance and transmittance measurement across a broad ultraviolet and visible wavelength range. Its long optical path, rigid optical structure, automatic calibration functions, and integrated analytical programs provide a practical solution for routine laboratory testing, quantitative analysis, research, and quality control.
A 520 mm long light path improves wavelength resolution by providing a longer optical route through the instrument. Combined with precision optical components and a rigid die-cast aluminum optical base, the instrument is designed to maintain stable optical alignment during repeated measurements. This construction helps support consistent results while reducing the influence of mechanical movement and environmental variation.
520 mm Long Optical Path for Better Resolution
The optical path is a critical factor in spectrophotometric performance. This UV Visible Spectrophotometer uses a 520 mm long light path to improve wavelength resolution and provide clearer spectral separation during measurement. The extended optical design is particularly useful when users need to distinguish closely positioned spectral features or perform detailed spectrum scanning.
Rather than relying only on a wide wavelength range, the optical architecture focuses on maintaining accurate transmission through the measurement path. This provides a stronger foundation for quantitative analysis, wavelength scanning, and other laboratory procedures requiring consistent spectral response.
Rigid Optical Structure for Stable Performance
All major optical components are mounted on a 16 mm-thick die-cast aluminum optical base. The rigid construction helps maintain the relative position of optical components and supports long-term measurement stability.
A stable mechanical foundation is important for spectrophotometric instruments because small changes in optical alignment can affect measurement repeatability. The rigid optical base minimizes unnecessary movement and provides a dependable platform for the light source, monochromator, detector, and other optical components.
This structural design makes the UV Visible Spectrophotometer suitable for laboratories where repeated measurements and dependable analytical performance are important.
Multiple Analytical Functions Built Into One Instrument
The instrument supports several commonly used analytical functions without requiring users to rely exclusively on external software. Spectrum scanning, standard curve analysis, kinetics, multi-wavelength measurement, and DNA/protein testing can be performed directly through the instrument interface.
These functions allow users to move from basic absorbance measurement to more advanced analytical procedures within the same platform. Spectral curves and corresponding measurement data can be displayed directly, making it easier to review results during testing.
Spectrum Scanning
Spectrum scanning allows users to observe absorbance or transmittance changes across a selected wavelength range. This function can help identify characteristic spectral features and evaluate the optical response of samples.
Standard Curve Analysis
Standard curve functionality supports quantitative analysis by relating measured absorbance to known concentrations. It can simplify concentration calculations when working with prepared standards and unknown samples.
Kinetic Measurement
Kinetic analysis is useful when absorbance changes over time need to be monitored. The instrument can collect and display measurement data to support studies involving time-dependent reactions and analytical processes.
Multi-Wavelength Testing
Multi-wavelength analysis enables measurements at selected wavelengths within a single analytical workflow. This can improve efficiency when several wavelengths are required for sample evaluation.
DNA and Protein Analysis
Dedicated DNA and protein testing functions make the instrument suitable for laboratories performing routine biomolecular measurements. By combining these functions with broad UV and visible wavelength coverage, the instrument can support a wider range of laboratory applications.
One-Button Automatic Calibration
Routine calibration is essential for maintaining reliable spectrophotometric measurements. The UV Visible Spectrophotometer incorporates one-button automatic calibration for baseline, wavelength, and dark current.
Instead of requiring separate manual procedures for each calibration function, users can initiate automatic calibration through a straightforward operation. This helps simplify instrument preparation and reduces unnecessary operating steps.
Automatic calibration is particularly useful in laboratories where instruments are used frequently by different operators. A consistent calibration process can contribute to better measurement repeatability and more convenient daily operation.
Clear Display and Convenient Data Access
A large high-definition LCD display provides direct access to measurement data, analytical curves, and operating information. The display is designed to make commonly used functions easier to monitor during testing.
For laboratories that need to review results directly at the instrument, on-screen visualization can improve workflow efficiency. Users can inspect spectral curves and measurement information without immediately transferring every result to another device.
The instrument also supports USB and parallel port output. USB connectivity 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 test-data printing.
PC Software for Extended Data Analysis
The supplied PC software extends the analytical capabilities of the UV Visible Spectrophotometer and provides computer-based operation and data management. Users can perform spectrum scanning, standard curve analysis, kinetic measurements, multi-wavelength testing, and DNA/protein analysis through the software interface.
Computer control can be particularly useful when laboratories need to review larger amounts of spectral data, manage measurement results, or perform analytical procedures from a workstation. The combination of instrument-based operation and PC software gives users greater flexibility when selecting a preferred workflow.
Broad UV and Visible Wavelength Coverage
The instrument covers a wavelength range of 190–1100 nm, supporting both ultraviolet and visible spectral measurements. This broad coverage allows one instrument to handle different analytical requirements without restricting users to a narrow spectral region.
