V-5800/UV-5800 Visible Spectrophotometer for Routine Photometric Analysis

Precise Wavelength Control for Reliable Measurements

A visible spectrophotometer is designed for routine photometric analysis where wavelength accuracy, measurement stability, and straightforward operation are essential. With a precision lead screw structure, the instrument provides accurate wavelength positioning and a wavelength resolution of up to 0.1 nm, supporting consistent measurements across different analytical tasks.

The complete numerical keypad allows operators to enter and adjust measurement parameters directly, including wavelength and concentration values. Automatic wavelength setting simplifies routine operation and reduces unnecessary manual adjustments during repeated testing.

Stable Optical Structure for Consistent Performance

Optical stability has a direct influence on measurement reliability. The instrument uses an 8 mm thick die-cast aluminum optical base to securely support the optical components. This rigid construction helps minimize structural movement and provides a stable platform for long-term laboratory operation.

The optical design is paired with an imported tungsten lamp for visible-light measurement. For ultraviolet applications, the UV version combines tungsten and deuterium lamps to provide a broader wavelength range. The selected light sources offer long service life, stable illumination, and low stray light for improved photometric performance.

Visible and UV Spectrophotometer Options

The product family includes visible and UV-visible configurations to accommodate different laboratory requirements. The visible version operates across 320–1100 nm, while the UV version extends the measurement range to 190–1100 nm.

This configuration makes the instrument suitable for laboratories that need either visible-range analysis or expanded UV-visible measurement capability without changing the basic operating approach.

Fast Standard Curve Development

Quantitative photometric analysis often requires a standard curve before unknown samples can be measured. The instrument supports a straightforward process for establishing standard curves and determining unknown concentrations, helping operators move efficiently from calibration to sample testing.

Its photometric range covers -0.3 to 3 A, 0–200%T, and 0–9999C, providing flexibility for different measurement modes and concentration-based applications. Stable optical performance also supports repeatable results when multiple samples need to be analyzed under consistent conditions.

Simple Data Transfer and Printing

Data management is an important part of routine laboratory analysis. The spectrophotometer provides both USB and parallel interfaces, giving laboratories different options for transferring or recording measurement results.

Through the USB port, the instrument can connect with a computer and operate with optional PC software. The parallel port can be connected to an optional micro thermal printer for direct printing of test data. This flexible output design allows users to select a data workflow according to their laboratory requirements.

Measurement Stability for Routine Laboratory Work

The instrument is designed to maintain stable photometric performance during continuous operation. Its stated stability is ≤0.001 A/30 min at 500 nm, while stray light is controlled to ≤0.05%T at 360 nm for the visible configuration and at 220 nm and 360 nm for the UV configuration.

Together with wavelength repeatability of ≤0.2 nm and photometric repeatability of ≤0.1%T, these specifications provide a practical foundation for routine absorbance and transmittance measurements.

Practical Operation and Standard Accessories

A visible spectrophotometer needs to balance analytical performance with everyday usability. The 128 × 64 dot LCD provides a clear interface, while the numerical keypad enables direct parameter entry. Automatic wavelength setting further simplifies repeated measurements.

Standard accessories include a 1 cm glass cuvette, with 1 cm quartz cuvettes supplied for the UV configuration. A power cord, user manual, and dust cover are also included, providing the basic equipment needed for installation and routine operation.

Applications for Photometric Analysis

This spectrophotometer can be used for laboratory applications that require controlled wavelength selection, absorbance measurement, transmittance measurement, concentration analysis, and standard curve development. Its visible and UV-visible configurations allow users to select the appropriate wavelength range according to the analytical method.

For laboratories handling routine quantitative testing, the combination of accurate wavelength control, stable optical construction, automatic settings, flexible data output, and standard curve functionality provides a practical platform for repeatable photometric analysis.
