Why is this process the one for you?

The Accurate One

Fill and freeze your products with the highest accuracy. With a filling accuracy of less than +/- 1mL and reproducible freezing recipes for your optimal result.

The Flexible One

Independent from type, manufacturer and size of your single-use bag, the modular platforms and single-use technologies will meet your requirements.

The Secure One

Automated aseptic filling at highest accuracy minimizes both operational human errors and overfilling of single-use bags. Controlled plate-based freezing and thawing of single-use bags prevents loss of product quality due to cryoconcentration and reproducible freezing and thawing.

The Trusted One

With more than 200.000 RoSS shells sold and 180 platform systems commissioned, Single Use Support is a trusted pioneer in Biopharma for optimizing drug substance handling.
