FSTest Fipronil Rapid Test Kit (10 Tests)

Product Overview

The FSTest Fipronil Rapid Test Kit (Colloidal Gold) is a professional-grade, rapid screening tool engineered for the qualitative detection of fipronil residues in agricultural fresh produce. Fipronil is a widely monitored phenylpyrazole insecticide. Ensuring strict residue tracking is vital for agricultural crop growers, food supply chain operators, and export compliance auditors striving to conform with global food safety standards and Maximum Residue Limits (MRLs).

By eliminating the immediate necessity for complex and costly laboratory infrastructure like HPLC or GC-MS, this field-ready assay compresses agricultural chemical extraction into a simplified, room-temperature workflow. It serves as an essential first-line defense in fresh produce logistics, crop management, and corporate food safety compliance screening programs.

Product Highlights & Key Benefits

· High-Speed Field Turnaround: Complete the entire workflow and read stable, highly reliable visual results within just 8 to 10 minutes post-sample-preparation.

· Highly Sensitive Baseline Detection: Calibrated to yield dependable screenings at a strict Limit of Detection (LOD) of 0.02 mg/kg (ppm) across various food matrices.

· Fully Self-Contained Kit Architecture: Arrives fully packed with all necessary consumables—including 10 test cassettes, 10 microwells, 1 bottle of Extracting Solution (35 mL), and 2 sampling bottles (30 mL).

· Definite Visual Interpretation: Utilizes a competitive lateral flow immunochromatographic assay format where the color intensity of the Test (T) line shares an opposite correspondence with the fipronil concentration, removing analytical ambiguity.

· High Specificity & Zero Cross-Reactivity: Proven to stay entirely unaffected by non-target agrochemicals. Samples containing 10 mg/L of common alternative treatments—including Carbofuran, Triazophos, Methomyl, and Emamectin benzoate—consistently return negative results.

· Safe & Non-Toxic Sample Prep: The specialized extraction solution supplied in the kit is certified as safe and non-toxic for operators, ensuring hassle-free processing on-site.

Technical Principle: Lateral Flow Immunochromatography

The test strip is based on a competitive lateral flow immunochromatography mechanism. The test cassette houses an integrated observation window containing an invisible Test (T) zone and a Control (C) zone before fluidics activation.
