Highlights

Why PBS-80

The PBS-80 extends proven processes to commercial production volumes while preserving the culture environment your cells have been thriving in. It is designed to help manufacturers increase output, support growing demand, and maintain process consistency across the product lifecycle.

Commercial-Scale

Manufacture large cell therapy batches at production-relevant volumes.

Automated

Standardize large-scale manufacturing with recipes, process control, alarms, and comprehensive data capture.

GMP-Ready

Designed for commercial manufacturing with single-use, cGMP-ready vessels and secure, audit-ready, 21 CFR Part 11-compliant software and IQ/OQ documentation.

High-Output

Support high-density, high-yield production using external perfusion systems and closed-system manufacturing workflows.

Vertical-Wheel 80L

The PBS-80 Vertical-Wheel FLUIDIX™ Vessel

The PBS-80 runs pre-sterilized, single-use Vertical-Wheel FLUIDIX™ 80L Vessels for commercial-scale manufacturing to meet the market demand of your therapy.

Pre-sterilized & single-use: no cleaning or re-validation between runs.

Consistent wheel geometry: the same mixing your cells will meet at every scale.

Closed system: reduces contamination risk across your workflow.

Single-use sensors: measure, track, and control pH and DO through integrated optical sensors.

PosteriPSC & PSCPerfusion Feed and External Oxygenation Utilized to Achieve Linear Scale-Up of iPSC Culture into an 80 L Vertical-Wheel BioreactorPBS-3PBS-15PBS-80PBS-Mini

PosterOpen document →

This poster describes linear scale-up of human induced pluripotent stem cell aggregate expansion across 0.1, 3, 15, and 80 L Vertical-Wheel bioreactors. A baseline small-scale process was used to establish operating conditions and assess reproducibility and robustness across media, operators, cell lines, and agitation rates. Perfusion-based media exchange was introduced at reactor scales of 3 L and above to address increasing settlement times and aggregate merging as vessel scale increased. Cell growth, aggregate size, metabolic consumption and production, and pluripotency markers were…

PosterOpen document →

This poster presents a three-dimensional process for linear scale-up of human induced pluripotent stem cell expansion from 0.1 to 80 L in Vertical-Wheel® Bioreactors. Cultures maintained growth, aggregate sphericity, pluripotency, karyotype, and functional pluripotency across scales. Serial aggregate culture and scalable harvest, concentration, and cryopreservation generated high-density working cell banks that retained viability, growth, genomic stability, and differentiation competence after thaw. The banks supported shortened endocrine, islet-like, and cardiomyocyte workflows through…

White PaperOpen document →

This white paper examines the economic and operational advantages of Vertical-Wheel® Bioreactors compared with planar culture and conventional stirred-tank systems for cell therapy manufacturing. Key cost drivers include expansion efficiency, labor, facility footprint, process scalability, batch reproducibility, and product quality. Published examples demonstrate increased cell yield, fewer processing steps, reduced labor, and improved facility utilization through single-use, closed-system operation. Low-shear, homogeneous hydrodynamics support consistent growth and critical quality…

App NoteOpen document →

This application note describes an hMSC manufacturing workflow using RoosterBio cell products, xeno-free media, and PBS Biotech Vertical-Wheel bioreactors. Studies evaluated microcarrier culture, fed-batch operation, harvest, scale-up, and cell quality. The low-shear, uniformly mixed environment supported robust attachment and cell densities up to 500,000 cells/mL within five days. Fed-batch processing improved media productivity by eliminating routine media exchanges and reducing labor. Comparable growth and metabolite control were maintained across development, pilot, and production…

PublicationOpen document →

This publication addresses bioprocess bottlenecks in large-scale human induced pluripotent stem cell expansion using Vertical-Wheel® Bioreactors. Computational fluid dynamics guided scalable inoculation, expansion, harvest, and serial-passaging protocols. Optimized fed-batch culture achieved greater than 30-fold expansion in six days from single-cell inoculation while maintaining homogeneous aggregate morphology. In-vessel aggregate dissociation achieved greater than 95% harvest efficiency and enabled serial passaging and scale-up. Expanded cells maintained normal karyotype…
