Benefits of partnership

There’s a reason Thermo Fisher Scientific already works with some of the world’s leading diagnostic companies.

Premium products: All Dynabeads products are validated with a unique level of reproducibility within and between batches. Patented manufacturing processes ensure careful control of bead parameters and product properties, securing their performance.

Unrivaled bead manufacturing: World-class manufacturing facilities can manufacture batches ranging in size from 1 g up to 2 kg with close to zero off-grade batches and flexible production scales. This meets relevant regulatory and quality systems compliance.

Comprehensive technical support: Extensive proprietary knowledge enables customized product development, decreases quality control costs, and increases manufacturing efficiency with hands-on support from R&D scientists.
