Paraquat Rapid Test Kit for Tea, Coffee, Banana & Grain | On-Site Herbicide Residue Screening

Not just a rapid test supplier — a long-term, globally proven food safety partner.

Product Description

The Paraquat Rapid Test Kit is designed for fast on-site screening of paraquat residues in high-risk agricultural commodities such as tea, coffee, banana, sugarcane, maize/corn, soybean, rice, tropical fruits and selected raw materials.

For exporters, processors and QC laboratories, the biggest risk is often not testing itself, but discovering paraquat residue risk too late — after raw materials have been purchased, processed, packed, shipped or inspected by buyers.

This rapid screening solution helps QC teams identify suspicious batches earlier, allowing high-risk materials to be separated, further confirmed, or prevented from entering production and export channels.

It is a practical pre-laboratory risk control tool for tea exporters, coffee processors, tropical fruit suppliers, grain processors, agricultural trading companies and food safety laboratories.

* Agricultural raw material traders

* Exporters

* Routine residue monitoring programs

Main value:

Check incoming raw materials before warehouse acceptance or production use, reducing the risk of contaminated batches entering downstream processing.

⸻

3. Fruit & Vegetable Export Screening

Suitable samples include:

* Banana

* Citrus / Orange

* Pineapple

* Mango

* Papaya

* Tomato

* Leafy vegetables

* Beans

Best suited for:

Why Paraquat Rapid Screening Matters

Paraquat is a highly sensitive residue-control target in international food and agricultural trade.

For professional buyers, the key question is not only:

“Can paraquat be detected?”

but:

“Can we identify the risk before the loss becomes expensive?”

Rapid screening helps users:

* Detect suspicious batches earlier

* Reduce delayed discovery after processing or shipment

* Lower unnecessary laboratory workload

* Improve raw material acceptance control

* Support export risk management

* Make faster QC decisions in real supply chains

This makes the kit especially useful for front-end screening before laboratory confirmation.

Key Application Scenarios

1. Raw Material Intake Screening

For tea, coffee, maize, soybean, rice, sugarcane-related materials and feed raw materials.

Helps processors and traders screen incoming materials before storage or production.

⸻

2. Export Pre-Shipment Screening

For tea, coffee, banana, tropical fruits, grain and agricultural commodities.

Helps exporters identify high-risk batches before container loading, customs inspection, buyer testing or shipment.

⸻

3. Plantation Crop & Processing QC

For coffee, banana, sugarcane, oil-palm-related materials and tropical crop supply chains.

Helps users screen residue risk before batch mixing, processing or commercial delivery.

⸻

4. Pre-Laboratory Risk Screening

For QC laboratories and companies handling many samples.

Helps users screen suspicious batches first and prioritize samples that require confirmatory laboratory testing.

⸻

Optional Reader-Assisted Analysis

Results can be interpreted visually or with an optional dedicated reader.

When used with the reader, the system can:

* Improve positive / negative interpretation

* Provide semi-quantitative reference values

* Support digital documentation and traceability

* Help manage batch-level QC records

This upgrade is suitable for exporters, laboratories, processors and large agricultural QC programs requiring more standardized data control.

⸻

Laboratory-Backed Screening Capability

We are not only a rapid test strip supplier.

Our strength lies in an integrated system covering:

* In-house R&D

* Large-scale manufacturing

* Colloidal gold rapid screening technology

* Independent laboratory verification

With our own laboratories equipped with LC-MS/MS and GC-MS/MS systems, we can evaluate how rapid screening results align with laboratory reference methods in validated applications.

This helps support product optimization, matrix validation and long-term reliability in real agricultural supply chains.

For buyers, this means the product is not just a low-cost strip, but a more reliable front-end screening solution supported by laboratory verification capability.

READ RESULTS WITH NAKED EYES

NEGATIVE:

The Test Line (T) is the same as or darker than the Control Line(C). It is negative.

POSITIVE:

The Test Line (T) is lighter than the Control Line(C),or there is no Test Line. It is positive.

INVALID:Reference Line Fails to appear

Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for an invalid result.

Review the procedure and repeat the test with a new test kit. Stop using the test kit immediately if the problem

is not solved and contact your local distributor.
