Ambr® 15 - Advanced Microbioreactor System

For Cell Line Selection and Early Process Development

Ambr® 15 Cell Culture 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.

Modernize CLD workflows 

Leave shake flasks and shaking plates behind to increase cell productivity and ensure robust performance.

Maximize throughput 

With up to 48 bioreactors running in parallel one operator can screen more clones and conduct multi-factor DOE studies.

Reduce experiment turnaround time

Single-use bioreactors save setup time, reducing staff costs and turnaround time.

Improve consistency through automation

Liquid handling automation reduces variation and risk of human error. 

Simplify clone ranking

A one-year license for Ambr® Clone Selection software is included,  simplifying ranking analysis.

Parallel Operation of up to 48 Microbioreactors

The Ambr® 15 Cell Culture system includes single-use vessels, an automated workstation and powerful software. Installed in a biosafety cabinet for aseptic operation, Ambr® 15 monitors and controls 24 or 48 microbioreactor cultures in parallel to provide a reliable microscale model for upstream processes. Implemented in CLD workflows of major pharma and biologics companies as well as research and academic institutes.

Culture Stations

Flexibilty Within and Across Culture Stations

The culture stations are located on the workstation deck: two culture stations in a 24-way system, four in a 48-way system – each station holds 12 microbioreactors. 

Temperature and stirring speed are consistent within a single culture station but can vary between different culture stations. 

pH, DO, gassing, liquids feeds and samples are controlled independently for each individual bioreactor within a culture station.
