Visible Spectrophotometer EZL-VS102 features multiple measurement modes that allow accurate sample analysis. It is widely used in chemical and agricultural testing for the quantification of samples.
The Visible Spectrophotometer EZL-VS102 offers a wavelength range of 320 to 1100 nm or 190 to 1100 nm, depending on the model configuration. This wide range covers the entire visible spectrum, near-infrared, and part of the ultraviolet region, making the instrument highly versatile. It allows users to perform both routine visible light analysis and advanced UV applications, such as nucleic acid or protein quantification. This comprehensive spectral coverage supports biological assays, chemical concentration tests, environmental monitoring, and pharmaceutical evaluations, enabling more thorough and flexible absorbance measurements across various sample types.
Ezilab’s Visible Spectrophotometer EZL-VS102 ensures high measurement reliability with wavelength accuracy of ±0.5 nm and repeatability of ?0.2 nm, ensuring the consistency of spectral data across multiple trials. It offers excellent photometric accuracy (±0.2%T) and repeatability (?0.1%T) for dependable optical readings. Additionally, the instrument demonstrates superior long-term stability, maintaining absorbance variation within ?0.001A over 30 minutes at 500 nm. This makes it particularly suited for kinetic studies, time-based assays, and other long-duration tests where signal drift must be minimized for reliable outcomes.
The Visible Spectrophotometer EZL-VS102 utilizes a high-quality tungsten (W) lamp for visible range measurements and optionally integrates a deuterium (D?) lamp for extended UV coverage. This dual-lamp system ensures complete spectral illumination from 190 to 1100 nm for both visible and UV-based assays. A silicon photodiode detector is employed for its high sensitivity, fast response, and durability, enabling accurate detection even at low sample concentrations. Together, these components provide high optical performance, long lamp life, and stable operation for applications requiring precision and spectral depth.
Ezilab’s Visible Spectrophotometer EZL-VS102 is designed for intuitive operation and ease of use. It features a 128 × 64 dot-matrix LCD, which displays absorbance, transmittance, and concentration readings. Users can conveniently store and recall up to 200 data sets and standard curves, improving workflow efficiency and supporting repeated analyses. The automatic wavelength setting, responsive keypad, and structured menu navigation simplify the operation. Whether used in teaching environments, clinical labs, or production settings, its simplicity and data recall functions make it accessible even for users with minimal technical experience.
Our Visible Spectrophotometer EZL-VS102 provides versatile connectivity options, including USB and parallel ports, for convenient data output. Through the USB interface, users can connect to a computer for data transfer, spectral scanning, and software-controlled operation using optional PC software, enhancing the analytical capabilities. The parallel port supports direct printer connection for immediate report generation. These features allow for easy data management, archival, and report documentation, ensuring compliance with lab protocols and facilitating integration into digital or networked laboratory systems for streamlined workflows.
The Visible Spectrophotometer EZL-VS102 is compatible with standard 10 mm path length glass or quartz cuvettes, making it suitable for a wide range of sample types, including aqueous solutions, organic solvents, and biochemical mixtures. The sample holder is designed for easy insertion and stable positioning, ensuring consistent light path alignment. Its compatibility with both glass (visible only) and quartz (UV-visible) cuvettes enhances its flexibility for UV-visible measurements. This makes the EZL-VS102 ideal for routine testing as well as specialized applications in research, education, and industrial quality control.
