Small-scale, multi-parallel bioreactors provide more process information for culture comparison in less time. Multiple experiments can assess different clones or cell lines, as well as the effects of pH, temperature, feeding, media, gassing rates and inoculation densities.

Ambr® multi-parallel bioreactors can handle your upstream process steps, from clone or cell line selection to process optimization, ensuring scalability because process data translates well into the 2L Univessel® SU and larger Biostat STR® systems.

Available models

Ambr® 15 Cell Culture generation 2 is a high throughput, automated bioreactor system for 24 or 48 parallel cultivations at the 10 –15 mL microbioreactor scale. This platform enables selection of the best clones, media and feeds under small-scale bioreactor conditions, ensuring a seamless scale-up. Implemented in Cell Line Development (CLD) laboratories worldwide, Ambr® 15 Cell Culture makes experimentation more cost effective by saving on labor, facility space, capital, media and consumables.

  • Process clone selection
  • Media development
  • Process optimization
  • Process characterization
  • Scale-down model development

Ambr® 250 Modular is an innovative, easy-to-use, expandable benchtop system that incorporates from 2 to 8 fully integrated single-use 100 – 250 mL mini bioreactors.

It has a wide range of applications in:

  • Process optimization
  • Process characterization
