Drug Product

Small-Batch Aseptic Fill-Finish

Aseptic fill-finish for preclinical and Phase I/II/III clinical supply — 2,000 to 5,000 vials per batch.

Small-Batch by Design

Clinical-scale batches are our core business, not an exception.

01/

Most CDMOs are built for commercial volumes and treat a Phase I batch as a favor. We are built the other way round. A 2,000-vial campaign is a normal week here, not a scheduling problem — which means no commercial-scale minimums, no back-of-queue slotting, and no waiting for a gap between commercial runs.

What we offer

1

Batch size 2,000–5,000 vials (20–50 L)

Run 2,000–5,000 vial batches as standard campaigns, with no commercial-scale minimum order.

2

Filling speed 25–50 vials/min · 10 mL RTU vials (ISO 8362)

Fill volumes up to 10 mL. Schedule clinical-phase programs into a dedicated small-scale suite rather than queuing behind commercial production.
