• USB 2.0 data transmission for convenient PC connectivity and data export
• Optional accessories available — single cell holder, fluorescence sample accessories, and excitation wavelength optical filters for extended measurement capabilities

Technical Specifications

Applications

The LI-4100 Fluorescence Spectrophotometer is suited to a wide range of laboratory applications where reliable fluorescence detection and quantification are required. In pharmaceutical quality control, it supports the analysis of fluorescent drug compounds, excipients, and trace impurities. Clinical and biochemical laboratories use it for enzyme activity assays, protein quantification, and biological marker analysis. Environmental monitoring labs rely on it for detecting organic pollutants, dyes, and contaminants in water samples. In food safety testing, the LI-4100 is effective for quantifying vitamins, detecting contaminants such as aflatoxin, and analysing fluorescent additives. Its kinetic determination capability also makes it valuable for reaction rate studies in biochemistry and chemistry teaching laboratories.

Benefits of the LI-4100

The LI-4100 occupies a practical, well-defined position in Lasany’s fluorescence spectrophotometer range — delivering the core capabilities laboratories need most, in a straightforward, easy-to-operate instrument. Its dual-mode operation means a single instrument can serve both routine fluorescence intensity measurements and luminous intensity analysis, reducing the need for multiple instruments in smaller laboratories. The normalized fluorescence comparison feature is particularly valuable in multi-operator or multi-session environments, where result consistency across different measurement runs is critical for data integrity. The six-stage adjustable response time gives operators flexibility to optimize signal detection for both strong and weak fluorescence emitters, while the long-life Hamamatsu Xenon lamp minimizes running costs and unplanned downtime. For laboratories seeking a capable, low-maintenance fluorescence spectrophotometer with a proven optical platform, the LI-4100 delivers outstanding value.
