Diazinon Rapid Test Kit
Brand: FSTest
5–8 mins Rapid Readout Time | 0.05–1 mg/kg Tunable Matrix LOD | 10 Tests Complete Kit Pack | 12 Months Shelf Life (4–30°C) |
The FSTest Diazinon Rapid Test Kit is a professional-grade, rapid screening tool engineered for the qualitative detection of diazinon residues in agricultural products.
Diazinon is a widely utilized organophosphorus insecticide and acaricide. By bypassing the need for complex, time-consuming laboratory infrastructure (such as HPLC or GC-MS), this field-ready kit compresses agricultural sample extraction into a simplified room-temperature workflow, serving as an indispensable first-line defense in fresh produce supply chains, tea plantations, and corporate food safety compliance monitoring programs in just 5 to 8 minutes.
High-Speed Field Turnaround: Complete the entire assay workflow and achieve highly reliable visual result readouts within just 5 to 8 minutes post-preparation.
Matrix-Specific Limits of Detection: Uniquely calibrated to adapt dynamically across various agricultural matrices, targeting regulatory cut-off thresholds ranging from 50 µg/kg (0.05 mg/kg) up to 1 mg/kg.
Fully Self-Contained Kit Architecture: Arrives fully packed with all necessary consumables—including 10 test cassettes, 10 microwells, 10 centrifuge tubes (2 mL), 50 mL Diazinon extracting solution, and 2 sampling bottles (30 mL).
Definite Visual Interpretation: Utilizes a competitive lateral flow format where an increasing insecticide concentration causes the Test (T) line to fade or completely disappear, removing subjective reading errors.
Ambient Transport & Easy Storage: Unopened test kits can be safely kept tightly sealed in a cool, dry location between 4–30°C for up to 12 months.

| Applicable Agricultural Produce Matrix | Targeted LOD (mg/kg) | Supernatant X (µL) | Extracting Solution Y (µL) |
|---|---|---|---|
| Kale, napa cabbage, bell peppers, zucchini | 0.05 mg/kg (50 µg/kg) | 100 µL | 0 µL |
| Cucumber, radish, strawberry, pineapple | 0.1 mg/kg | 100 µL | 100 µL |

| Pome fruits (apples, pears) | 0.3 mg/kg | 100 µL | 500 µL |
| Cabbage, broccoli, spinach, lettuce, head lettuce, tomatoes, carrots | 0.5 mg/kg | 100 µL | 900 µL |

Extensively validated across diverse agricultural commodities:
STEP 1 Extraction Cut fresh sample into 0.5 cm pieces. Weigh 2 g into sampling bottle, add 3 mL extracting solution, shake 1 min, let stand 1 min. (Centrifuge if cloudy). | STEP 2 Matrix Dilution Pipette X µL clear supernatant into a 2 mL tube, add Y µL extracting solution according to the matrix guide, and swirl/shake to mix thoroughly. | STEP 3 Microwell & Load Ensure 20–40°C environment. Pipette 100 µL test solution into microwell, mix 3–5 times, stand 3 min. Transfer 100 µL to cassette sample hole. | 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 a strong, distinct red band. Diazinon 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 → Diazinon 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 X & Y dilution ratio 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, 10 Microwells, 10 Centrifuge tubes (2 mL), Diazinon extracting solution (50 mL) x1, 30 mL Sampling bottles (x2), User Manual.
Required Equipment (Not Provided): Scissors, electronic balance (2 g precision), micropipettes (X & Y µL, 100 µL), vortexer, centrifuge (optional, for turbid extracts), and timer.
