The black latex microspheres can be used for qualitative and semi-quantitative detection by dyeing blank microspheres through a unique surface modification process. With bright color, the black latex microspheres are suitable for agglutination tests, lateral flow and other technical platforms. The single batch capacity exceeds 500 million tests, with excellent batch-to-batch consistency, which can provide customers with high quality products stably.
