Bangs Laboratories has supplied microspheres to diagnostic companies, instrument manufacturers, and researchers in the life sciences for 30 years. During this time, our synthesis capabilities have grown, encompassing silica and superparamagnetic microspheres in addition to traditional polymer compositions. We are skilled at dyeing, coating, and surface modification of microspheres, and offer many versions of our core products to meet the unique needs of our customers. Our core capabilities are also reflected in specialized products for flow cytometry and instrument calibration. We additionally offer custom formulations, preparations, and packaging for our OEM customers.
