3 Excitation UV Filters and 3 Emission Visible Filters Sensitivity 01 ppm

Uses UV excitation filters 3 wavelengths and visible emission filters 3 wavelengths, Provides high sensitivity up to 0.1 ppm or better.

1. Application

Fluorometers are used for high-sensitivity trace analysis, especially where UV-Vis is not sensitive enough:

Environmental testing (trace pollutants in water)
Pharmaceutical analysis (low concentration drug detection)
Clinical diagnostics (biomolecules, enzymes)
Food & beverage quality testing
Chemical research and fluorescence studies
Detection of vitamins, dyes, and fluorescent compounds

2. Compliance Standard

Typical compliance includes:

GLP (Good Laboratory Practice)
GMP (Good Manufacturing Practice)
ISO 9001 / CE certification
Pharmacopoeia standards (USP / IP / BP)
Electrical safety standards (IEC)

3. Product Description

A microprocessor-based filter fluorometer designed for trace-level detection:

Uses UV excitation filters (3 wavelengths) and visible emission filters (3 wavelengths)
Measures fluorescence intensity proportional to analyte concentration
Provides high sensitivity up to 0.1 ppm (or better)
Compact and easy to operate with digital display
Ideal for routine lab and field analysis

Unlike spectrophotometers, it detects emitted light, giving much higher sensitivity.
