Why Vertical-Wheel

Built For This Cell Type.

Gentle on shear-sensitive cells

Uniform low-shear mixing protects hMSC viability and phenotype while keeping microcarriers or aggregates suspended.

Microcarrier-optimized

Even microcarrier suspension, including customizable and dissolvable options that improve harvest and direct visualization.

Fed-batch productivity

Xeno-free fed-batch processes lift final cell yields and EV cargo across 0.1 L to 50 L scales.

Applications

  • BM-MSC expansion
  • Cord-blood MSC
  • Adipose-derived MSC
  • Microcarrier culture
  • Fed-batch processes
  • MSC-derived EVs

Systems for This Cell Type

Each system carries the note explaining why it suits this cell type.

  • PBS-MiniProcess & microcarrier optimization
  • PBS-3Microcarrier GMP-readiness
  • PBS-15Clinical-scale capacity
  • PBS-80Commercial (demonstrated to 50 L)
0.1–50 L

A xeno-free hMSC process maintained critical quality attributes across 0.1 L, 3 L, 15 L and 50 L Vertical-Wheel® scales.
