FSTest Carbofuran Rapid Test Kit (10 Tests)

Product Overview

The FSTest Carbofuran Rapid Test Kit (Colloidal Gold) is a professional-grade, rapid screening tool engineered for the qualitative detection of carbofuran residues in agricultural fruits and vegetables. Carbofuran is a widely monitored and highly regulated carbamate 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, 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.

·  Extensive Vegetable & Fruit Matrix Application: Validated for broad adaptability, covering Bulb, Brassica, Leafy, Solanaceous, Cucurbit, Legume, Stem, Root/Tuber, Aquatic, Sprout, and other vegetable groups, as well as Citrus, Pome, Stone, Berries, Tropical/Subtropical fruits, and Melons.

· Definite Visual Interpretation: Utilizes a sandwich 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 1 mg/L of common alternative treatments—including Chlorpyrifos, Triazophos, and Chlorothalonil—consistently return negative results.

· Safe & Non-Toxic Formulation: 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 is based on a sandwich lateral flow immunochromatography assay. The test cassette houses an integrated observation window containing an invisible Test (T) zone and a Control (C) zone before fluidics activation.

Results Determination & Action Guide

· Negative (-): Both the Control (C) line and Test (T) line develop a strong, distinct red band. This confirms that carbofuran insecticide residues are safely below the targeted regulatory threshold limit.

· Positive (+): The Control (C) line develops normally, but the Test (T) line is visibly lighter or fails to appear completely. This indicates that insecticide residues meet or exceed the designated threshold limit.

· Invalid: The Control (C) line fails to show any visible color band, regardless of the appearance of the T line. This signals an operational error, an uncalibrated pipette, or a compromised strip. The sample must be re-tested using a brand new cassette.
