BioPure Vertical-Wheel® · 60 mL → 80 L

One wheel. Five scales.
Zero re-engineering.

From a 60 mL discovery flask to an 80 L GMP run — the same gentle geometry, the same CQAs, the same cells.

PBS Vertical-Wheel® impeller: open hoop containing three pitched propeller blades on a horizontal axle.

The Vertical Wheel advantage

Low-shear mixing.
Linear scale-up.

Stirred-tank impellers tear delicate cells apart. The Vertical-Wheel® uses a single, gentle mixing geometry that scales identically from 60 mL to 80 L — preserving viability, potency, and CQAs across every transfer.

Shear stress92% lower
Mixing uniformity99%
Cell viability after 7d96%
Linear scale-up factor95%
