Why BPSSU for Downstream?

Why BPSSU

Downstream can't wait.

When purification or fill is the bottleneck, you need assemblies on your timeline, not your supplier's. BPSSU's typical turnaround is 8 weeks.

Complete fluid paths

TFF, chromatography, filtration, and final-fill assemblies all from one source with no need to coordinate across vendors.

Gamma-sterilized

Downstream and final-fill assemblies delivered sterile and fully documented for GMP and clinical use per request.
