The FSTest Carbofuran Rapid Test Kit 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. 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, serving as an essential first-line defense in fresh produce logistics, crop management, and corporate food safety compliance screening programs in just 8 to 10 minutes.

2. 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 Commodity Matrix Adaptability: Validated across Bulb, Brassica, Leafy, Solanaceous, Cucurbit, Legume, Stem, Root/Tuber, Aquatic, Sprout, Citrus, Pome, Stone, Berries, Tropical/Subtropical fruits, and Melons.
High Specificity & Zero Cross-Reactivity: Proven entirely unaffected by non-target agrochemicals up to 1 mg/L (including Chlorpyrifos, Triazophos, and Chlorothalonil).
Safe & Non-Toxic Formulation: Supplied with a specialized extraction solution certified as safe and non-toxic for operators, ensuring hassle-free processing on-site.

5. Test Procedure

STEP 1

Comminution

Cut fresh sample into 0.5 cm pieces. Weigh 1 g into sampling bottle, add 10 mL Extracting Solution, vortex/shake 1 min, let stand 1 min.

STEP 2

Clarification

Check supernatant clarity. If liquid layer is cloudy, transfer 1 mL into a centrifuge tube and centrifuge at 4000 rpm for 3 minutes.

STEP 3

Load Cassette

Ensure 20–40°C environment. Mount exactly 80 µL of prepared clear supernatant directly into the sample hole of cassette. Start timing.

STEP 4

Read at 8–10 Mins

Interpret visual lines strictly at 8–10 minutes. Visual readouts become strictly invalid after 10 minutes due to late chemical shifts.

Visual Results Determination Guide:

Negative (-): Both Control (C) line and Test (T) line develop strong, distinct red bands. Carbofuran residue is safely below 0.02 mg/kg.
Positive (+): Control (C) line develops normally, but Test (T) line is visibly lighter or fails to appear → Carbofuran residue ≥ 0.02 mg/kg threshold limit.
Invalid: Control (C) line fails to show any visible color band. Re-testing with a new cassette is required.

6. Performance & Crucial Operational Controls

Adhere to strict operational parameters to ensure maximum screening accuracy:

Qualitative Screening Purpose: Engineered strictly for qualitative preliminary screening; not intended for precise quantitative concentration evaluation.
Time-Sensitive Exposure: Perform test within 1 hour after removing cassette from protective packaging to avoid moisture interference.
Strict Time Window: Read visual test results strictly between 8–10 minutes after loading cassette; results observed after 10 minutes are invalid.

7. Included Components & Auxiliary Equipment

Kit Components Included: 10 Test cassettes, Extracting Solution (100 mL) x1, 30 mL Sampling bottles (x2), User Manual.
Required Equipment (Not Provided): Scissors, electronic balance (1 g precision), micropipette (80 µL), centrifuge (optional, for turbid extracts), and timer.
