The BIOSTAT A from Sartorius Stedim Biotech is a compact bioreactor/fermenter designed specifically as an entry-level model for fermentation and cell culture as well as for educational purposes. The system's control tower features a complete array of measurement and control functions like easy-load peristaltic pumps, an aeration module and conveniently accessible probe ports and supply connections. The compact design saves valuable space in your lab.The BIOSTAT A's new aeration system provides automatic control of all gas lines with continuous gas flows. That means no further manual adjustment of rotameters is necessary and any problem with pulsed aeration is a non-issue. The system is incredibly easy to operate: all the user has to do is connect the aeration hoses, configure the aeration profile and enter the DO setpoint. Using the BIOSTAT A for cell culture applications, aeration with four gases (air, O2, CO2 and N2) is possible for controlling pH and DO. The microbial version allows aeration with two gases (air and O2).
The new bioreactor is equipped with digital pH and DO probes. These help users immediately recognize whether you can confidently use a probe for the next cultivation process. Thanks to the moisture-resistant plug connection, secure data transmission is also always assured.
Each BIOSTAT A for microbial fermentations is equipped with a chiller that effectively removes heat from the device. This reduces your cooling water consumption and your laboratory does not need to be equipped with a cooling water system. All the user needs to operate the system is electricity and a gas supply.
Thanks to the intuitive user interface, operating the new bioreactor is ideal for beginners because it prevents operating errors and reduces training time to a minimum. Optional operation with a tablet or smartphone is part of the Advanced package and allows you to monitor and control the system, whether you're on the go, in the lab, at the office or at home.
BIOSTAT A is available with various single-walled borosilicate glass culture vessels with maximum working volumes of one, two or five liters. In addition to the UniVessel made of glass, the UniVessel SU disposable bioreactor can also be operated with the same control tower and offers a maximum working volume of two liters.
