Cellab® Bioreactor System

Parallelization of the hollow fiber infection model for your PK/PD studies

An in vitro hollow fiber model has already provided proven results for the preclinical development of anti-tuberculosis drugs and represents a qualified system model by the EMA (see CHMP Qualification Opinion [1]). It offers predictive accuracy higher than 90 % and offers significant advantages to animal models or static assays [2].



  • Preclinical PK/PD during the development of antimicrobial medicinal products for infectious disease
  • Efficacy optimization of dosing regimens and drug combination therapies e.g. in tuberculosis
  • Simulation of the in-vivo activity and resistance of antibiotics
  • Replacement of animal studies during preclinical drug development

Why in-vitro hollow fiber model systems improve your PK/PD analysis

  • PK/PD indices are determined based on larger pool of infected organisms
  • A wider dosing range of the drug inocula as it is possible and justifiable in animal models
  • Continuous and reliable measurement of the AUC/MIC, Peak/MIC, half-lives and time-kill curves
  • Precisely monitoring of the absorption and elimination kinetics
  • Prevent bacterial elimination using semipermeable membranes

Benefits for your PK/PD studies working with the Cellab® DisposableSet with 5 small hollow fiber modules in parallel

The Cellab® Bioreactor System consists of a disposable set equipped with different single use bioreactor configurations including hollow fiber membrane modules and a reusable docking station containing all components to operate the disposable set and to communicate with the control computer. The Disposable Sets are delivered fully assembled and presterilized including up to 5 hollow fiber modules with 5 individual central media reservoirs plus additional sample ports, tubing and connectors. The whole system is designed to be operated in a standard CO2-incubator.

  • Quick equilibration of the antibiotic level in the ECS and ICS
  • Reduce the risk of contamination in closed semi-automated systems
  • Simultaneous evaluation of multiple dosing regimens in up to 5 HF-models in parallel
