With the introduction of modules MX4/1 and MF4, DASGIP improves gassing options at pilot scale and in industrial biotechnology

DASGIP AG, a leading manufacturer of parallel bioreactor systems, expands its range of gassing solutions for fermentation and cell cultivation by introducing the new modules MX4/1 and MF4. MX4/1 supplies reactors up to pilot scale, while MF4 has been designed specifically to meet the requirements of industrial biotechnology.

DASGIP’s new gas mixing system MX4/1 complements their best-selling single module MX4/4. Both products provide a mass flow controlled mixture of air, oxygen, carbon dioxide and nitrogen. While MX4/4 serves four separate culture vessels, MX4/1 pipes the gas mixture into one reactor at a rate of up to 2,000 standard litres per hour (sL/hr). MX4/1 is thereby ideally suited for gassing requirements at pilot scale. Electronic mass flow controllers and setpoints at each outlet enable precise and individual adjustment of oxygen and carbon dioxide concentrations, offering more reproducible results. Users can now also define the mixture components of incoming gases, e.g. artificial oxygen composed of 90% oxygen and 10% nitrogen in order to use gas mixtures according to their security standards.

The new DASGIP MF4 has been developed for processes requiring unconventional gasses such as methane and carbon monoxide in biofuel development. MF4 provides mass flow controlled gassing up to 2000sL/hr for four parallel channels and users are free to select any four input gasses to suit their needs. Independent gas leads ensure different gases can be combined even though they would normally react with each other.

Both gas mixing appliances as well as the MF4 are equipped with sensitive pressure sensors to ensure gassing is automatically stopped when excess pressure occurs. This ensures a high measure of workplace and production safety when handling glass vessels and bags. With its new products MX4/1 and MF4, the market leading MX4/4, and the gassing module RX2/4, DASGIP AG serves a broad range of users and requirements in cell cultivation and fermentation.

DASGIP will be demonstrating its new gassing systems at the Biotechnica 2007 in Hanover, Germany (9 - 11 October 2007, booth G25, hall 9).
