Procymidone Rapid Test Kit
Brand: FSTest
5–8 mins Rapid Readout Time | 2–10 mg/kg Tunable Matrix LOD | 10 Tests Complete Kit Pack | 12 Months Shelf Life (4–30°C) |
The FSTest Procymidone Rapid Test Kit is a professional-grade, rapid screening tool engineered for the qualitative detection of procymidone residues in fresh fruits and vegetables.
Procymidone is a widely monitored dicarboximide fungicide. 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, delivering highly reliable visual results in just 5 to 8 minutes for agricultural growers, produce supply chains, and food safety compliance monitoring programs.
High-Speed Field Turnaround: Complete the entire assay workflow and read stable visual result readouts within just 5 to 8 minutes post-sample-preparation.
Versatile Base & Matrix Detection Limits: Calibrated to yield dependable screenings at a base Limit of Detection (LOD) of 2 mg/kg (ppm), with specific matrix adjustments optimized for thresholds ranging from 2 mg/kg up to 10 mg/kg.
Comprehensive Kit Architecture: Arrives fully packed with essential consumables—including 10 test cassettes, 20 centrifuge tubes (2 mL), 1 bottle of extracting solution (100 mL), and 2 sampling bottles (30 mL).
Definite Visual Interpretation: Utilizes a competitive lateral flow immunochromatographic format where the color intensity of the Test (T) line shares an opposite correspondence with the procymidone concentration, removing analytical ambiguity.
Ambient Logistics & Stable Preservation: Unopened test kits can be safely kept in a sealed, cool, and dry location between 4–30°C for a full 12-month shelf life.

Extensively validated across diverse fresh produce commodities:
STEP 1 Extraction Cut fresh sample into 0.5 cm pieces. Weigh 2.0 ± 0.1 g into sampling bottle, add 5 mL extracting solution, shake 1 min, let stand 1 min. (Centrifuge if cloudy). | STEP 2 Matrix Dilution Execute the specific single-step or two-step serial dilution protocol as defined in the matrix guide table based on the commodity being verified. | STEP 3 Load Cassette Ensure 20–40°C environment. Mount exactly 100 µL of prepared final sample solution directly into the sample hole of the cassette. Start timing. | STEP 4 Read at 5–8 Mins Interpret visual lines strictly at 5–8 minutes. Visual readouts become strictly invalid after 8 minutes due to late chemical shifts. |
Negative (-): Both Control (C) line and Test (T) line develop strong, distinct red bands. Procymidone residue is safely below the targeted matrix LOD limit.
Positive (+): Control (C) line develops normally, but Test (T) line is visibly lighter or fails to appear → Procymidone residue ≥ targeted matrix LOD limit.
Invalid: Control (C) line fails to show any visible color band. Re-testing with a new cassette is required.
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.
Matrix Dilution Accuracy: Strictly execute the single-step or two-step dilution protocol corresponding to the commodity type to calibrate reading against exact regulatory MRL cutoffs.
Strict Time Window: Read visual test results strictly between 5–8 minutes after loading the cassette; results observed after 8 minutes are invalid.
Kit Components Included: 10 Test cassettes, 2 mL Centrifuge tubes (x20), Extracting solution (100 mL) x1, 30 mL Sampling bottles (x2), User Manual.
Required Equipment (Not Provided): Scissors, electronic balance (2.0 ± 0.1 g precision), micropipettes (X & Y µL, 100 µL), vortexer, centrifuge (optional, for turbid extracts), and timer.
