Who We Are

More Than a Rapid Test Kit Manufacturer

Company Overview

    NANKAI Biotech is built as an integrated rapid testing platform, combining product development, large-scale manufacturing, laboratory-backed verification, and real-world application support.

We focus on practical food safety screening solutions that help customers identify risks earlier — before raw materials enter storage, production, shipment, or market circulation.

Our products are widely used for pesticide residues, mycotoxins, veterinary drug residues, antibiotics, heavy metals, aquaculture safety, and other food safety applications.

From on-site rapid screening to laboratory-supported validation, we help global customers build faster, simpler, and more reliable quality control workflows.
