ambr® 250 modular

ambr® 250 minibioreactors are single-use and controlled by an automated workstation. They are ideal for generating a design space. The system builds on our successful micro-bioreactor technology, adding increased fermentation volumes as well as individual bioreactor temperature and impeller control. ambr® 250 provides an efficient, high-throughput scale-down model for process development and can easily be scaled up to our BIOSTAT STR® bioreactors.

ambr® 250 high throughput

The ambr® 250 high throughput workstation is ideal for automating DoE approaches to cell culture process development in support of QbD studies. It allows the rapid evaluation of a wide range of bioreactor conditions and can be readily scaled-up to our BIOSTAT STR® single-use bioreactors. The workstation allows the independent, parallel control of 12 or 24 single-use bioreactor with working volumes of 100 to 250 mLs.

Our MFCS sets a new standard in bioprocess data management. It simply and efficiently allows data acquisition, monitoring and control of cell culture and microbial processes. It is a feature-rich, GAMP category 4 software package – based on over 25 years of experience and 3,000 installations worldwide. The integrated MODDE DoE for design of experiments (DoE) and SIMCA software for multivariate data analysis (MVDA) enables the fast and straightforward implementation of a QbD approach to drug development. The S88 tool enables easy and safe recipe transfer across scales.

The BIOSTAT STR® familiy consists of a range of completely single-use bioreactors with a conventional stirred-tank bioreactor design that is ideal for high-density cell culture applications. The range has true scalability from process development through pilot to production scales minimizing both the effort associated with scaling up cell culture processes and the risk of process transfer even to larger-scale bioreactors.

Quality by Design – Develop your scalable design space

Nova BioProfile® FLEX2

BioProfile® FLEX2 combines Nova’s groundbreaking MicroSensor Card technology with optical measurement and freezing point osmometry for an automated and comprehensive cell culture analyzer. Compared to the previous generation BioProfile® FLEX there is no maintenance for any of the 11 chemistry and gas sensors, sample volume for the full text menu is reduced by 75% to 265 microliters (400-500 microliters when integrated with ambr® 15), and test time is also reduced to just 4.5 minutes (6-7 minutes when integrated to ambr® 15). Simple touchscreen operation, fast analysis time and automated quality control (QC) provide maximum simplicity, labor savings, and workflow efficiency for cell culture monitoring.

Biopharmaceutical companies are increasingly adopting a QbD approach to control strategy development, spurred on by regulators and the promise of greater operating flexibility. Advances in upstream technology will make is easier for these firms to understand the link between their product critical quality attributes (CQAs) and critical process parameters (CPPs). This article describes how an upstream platform solution can shorten development timelines and reduce costs.

Quality by Design by
Prof. José Menezes, 4Tune Engineering,
at the European Upstream & Downstream Forum 2016

Biologics are three orders of magnitude more complex than drugs such as Aspirin. Prof. José Menezes, 4Tune Engineering, believes the biopharma industry can help ensure patient safety using a Quality by Design (QbD) approach that selects and aggregates the right PAT tools and then performs a multivariate data analysis (MVDA) on the acquired data. In this way, biotechnology companies can reach the market faster, compare batches more effectively and solve bioprocessing problems.
