Why Vertical-Wheel

Built For This Cell Type.

Potency preserved

Gentle mixing maintains cytotoxic potency, matching or exceeding static G-Rex in head-to-head expansion.

Allogeneic scale

One platform spans 60 mL to 80 L for parallel process optimization and commercial allogeneic supply.

Perfusion-intensified

Integrates Repligen XCell® ATF perfusion for high-density CAR-NK expansion at 3 L and beyond.

Applications

  • NK expansion
  • CAR-NK
  • Allogeneic immunotherapy
  • Perfusion culture
  • NK-derived EVs
