The FSTest Cypermethrin Rapid Test Kit is an advanced, competitive lateral flow immunochromatographic assay engineered for rapid qualitative screening of cypermethrin pesticide residues in fruits and vegetables.

Cypermethrin is a widely utilized synthetic pyrethroid insecticide subject to strict Maximum Residue Limits (MRLs) globally. With a rapid turnaround of just 5 to 8 minutes for visual result readout (total assay time: 15–20 minutes), this kit empowers agricultural producers, wholesale distributors, food processing plants, and food safety inspection agencies to perform highly reliable on-site pesticide residue screening without the need for complex, costly chromatography equipment.

2. Key Benefits

High Sensitivity (2 mg/kg LOD): Features an accurate Limit of Detection at 2 mg/kg, effectively monitoring maximum residue levels (MRLs) for agricultural trade compliance.
Fast Visual Readout in 5–8 Minutes: Delivers prompt visual qualitative results, dramatically reducing inspection and release times for fresh produce batches (15 min for single samples; ~20 min for 6-sample batches).
Eco-Friendly & Non-Toxic Extraction: Formulated with a safe, non-toxic extraction solution that minimizes health and environmental risks for field operators.
Exceptional Analytical Specificity: Exhibits zero cross-reactivity with common agrochemicals; negative results confirmed against 1 mg/L of Carbendazim, Carbofuran, Chlorpyrifos, and Triazophos.
Dual Reading Compatibility & Ambient Storage: Supports both visual naked-eye colorimetric evaluation and automated instrument readings for digitized record keeping, stored safely at room temperature for 12 months.

4. Applicable Sample Types

Optimized specifically for identifying pyrethroid pesticide residues in fresh agricultural produce:

Leafy Vegetables (Spinach, cabbage, lettuce, celery, brassicas) Solanaceous & Cucurbits (Tomatoes, peppers, eggplants, cucumbers) Root & Tuber Vegetables (Carrots, radishes, potatoes) Orchard Fruits & Berries (Apples, pears, peaches, grapes) Agricultural Farms, Wholesale Markets & Customs Quarantine

5. Test Procedure

STEP 1

Extraction

Chop sample (> 10 g) into 0.5 cm pieces. Weigh 2.0 g (±0.1 g) into a 30 mL sample bottle, add 3 mL Extraction Solution, shake vigorously 1 min, let stand 1 min.

STEP 2

Clarification

Check extract clarity. If the solution is visibly turbid, transfer 1 mL into a centrifuge tube and centrifuge at 4000 rpm for 3 minutes before taking supernatant.

STEP 3

Microwell Reaction

Ensure 20–40°C environment. Pipette 100 µL supernatant into a microwell, mix up and down 3–5 times with pipette, and incubate undisturbed for 3 minutes.

STEP 4

Load & Read (5–8 Mins)

Transfer all mixed solution from microwell into cassette sample well. Interpret visual lines strictly at 5–8 minutes. Results are completely invalid after 8 minutes.

Visual Results Determination Guide:

Negative (-): Both Test (T) line and Control (C) line appear clearly. T line color intensity is equal to or darker than C line → Cypermethrin is absent or below 2 mg/kg. Sample passes screening.
Positive (+): Control (C) line appears distinctly, while Test (T) line is invisible or visibly lighter than C line → Cypermethrin residue is present at or above 2 mg/kg. Confirmatory testing recommended.
Invalid: Control (C) line fails to appear, regardless of whether T line is present or absent. Re-test with a new unit.

6. Performance & Crucial Operational Controls

Adhere to strict operational parameters to ensure maximum screening accuracy:

Qualitative Screening Purpose: Intended for rapid qualitative field screening; positive samples should be confirmed using standard chromatographic methods (e.g., GC-MS / LC-MS).
Analytical Specificity: Exhibits zero cross-reactivity with common agrochemicals; negative results confirmed against 1 mg/L of Carbendazim, Carbofuran, Chlorpyrifos, and Triazophos.
Moisture Protection: Begin testing within 1 hour after removing the test cassette from the foil packaging to prevent ambient humidity from invalidating the strip.
Strict Time Window: Read visual test results strictly between 5–8 minutes post-loading; any lines observed after 8 minutes are invalid.

7. Included Components & Auxiliary Equipment

Kit Components Included: 10 Test Cassettes (individually sealed with desiccant in foil pouches), 10 Microwells (pre-coated reagent wells), 1 bottle of Cypermethrin Extraction Solution, 2 Sample Bottles (30 mL), User Instruction Manual.
Required Equipment (Not Provided): Knife/scissors, precision balance (±0.1 g), timer, micropipette (100 µL range) & tips, centrifuge tubes, and centrifuge (optional, for turbid extracts).
