The One‑Step Beta‑Lactam Rapid Test is a lateral‑flow immunoassay kit designed to detect beta‑lactam antibiotic residues in milk. The test strip contains a nitrocellulose membrane that captures the target analytes, while a colloidal gold conjugate provides a visual signal. Results appear within a reading time of 5 to 10 minutes after applying the sample. The kit is supplied in a sealed plastic casing for field use.
The assay follows a competitive format, where the presence of beta‑lactam residues reduces the intensity of the test line. Typical detection limits for penicillin‑type antibiotics are around 0.1 µg L⁻¹, although exact sensitivity depends on the specific conjugate. The membrane and reagents are stable when stored at 2 °C to 8 °C, with a typical shelf life of 12 months. The test is calibrated to meet EU and FDA maximum residue limits for beta‑lactams in dairy products.
Dairy processors, quality‑control laboratories and food‑inspection agencies use the kit to verify compliance before product release. The supplier offers the test in individual cassettes, but does not disclose minimum order quantity, lead time or payment terms. Importers should request confirmation of packaging size, batch numbers and any available validation certificates. Clarifying these details will help integrate the rapid test into routine monitoring programmes and avoid supply interruptions.

First, confirm that the rapid test kit is formulated for milk matrices, that the nitrocellulose membrane and colloidal gold conjugate are supplied as described, and that the detection limit meets your regulatory requirements. Ask the supplier for a validation report or a certificate of analysis that demonstrates performance against EU and FDA residue limits. This verification helps avoid receiving a kit that cannot deliver the necessary sensitivity.
Next, discuss logistics: request the Incoterms the supplier can provide (FOB Shenzhen, CIF Shanghai or others), clarify the expected lead time for the batch size you need, and verify whether the plastic cassettes are packed on pallets with moisture protection. Confirm payment options such as a letter of credit or advance payment, and ensure the commercial invoice includes the correct HS code for diagnostic test kits. Aligning these details with your freight forwarder will smooth customs clearance.
Finally, arrange quality checks before the goods leave the factory. Insist on a third‑party inspection that confirms the membrane integrity, gold conjugate activity and buffer pH, and obtain the corresponding test certificates. Upon arrival, perform an incoming inspection using a known positive milk sample to verify that the kit functions as expected. Document all inspection results to maintain traceability for your quality‑assurance system.
