The Beta-lactam rapid test from Span Biotech Ltd. is a lateral flow immunoassay designed for qualitative detection of beta-lactam antibiotics in milk, delivering results in under 10 minutes. The kit interprets positive results as a single C band, negative as both C and T bands, and invalid if no C band appears, with a 12-month shelf life when stored at 2-8°C away from direct sunlight. All reagents must be at room temperature before use, and the test strip must remain sealed in its foil pouch until immediately before application.
This test demonstrates high specificity, returning negative results when exposed to 100 ppm of non-beta-lactam antibiotics such as chloramphenicol, aminoglycosides, tetracyclines, macrolides, and sulfonamides. The assay is optimized for fresh, homogeneous liquid milk samples without caking or precipitation, and it cannot be reused or applied to powdered milk or water as a control. Components are pre-tested as standard batch units, and mixing parts from different lot numbers is prohibited.
Span Biotech Ltd. positions this kit as a field-screening tool for dairy processors, farms, and quality control labs that require on-site antibiotic residue monitoring. It is particularly suited for bulk milk tanker testing, where rapid results enable immediate decision-making on acceptance or rejection. For quantitative analysis, confirmatory methods like ELISA or HPLC are recommended, as the rapid test is limited to qualitative detection.

Before ordering, verify that the Beta-lactam rapid test meets the regulatory requirements for your target market, such as EU or FDA approvals for dairy antibiotic screening. Confirm the kit’s detection range aligns with your threshold needs, as sensitivity varies by beta-lactam compound. Request the certificate of analysis for the lot number to ensure the test strips have been quality-controlled as a standard batch unit.
Clarify logistics such as lead time, which is not specified, and the minimum order quantity, as these are critical for planning bulk purchases. Discuss Incoterms (e.g., FOB Shenzhen) and payment terms to avoid delays at customs. The supplier’s harbor-tier status suggests established export processes, but confirm their experience with your country’s import regulations for diagnostic kits.
For quality checks, inspect the foil pouches for intact seals and desiccant upon receipt, as moisture exposure invalidates the test. Request the supplier’s recommended storage and handling protocols to maintain kit stability during transit. Ensure the expiration date on the pouch allows sufficient time for use, and validate the test’s performance with a confirmed negative milk sample before full deployment.
