BIOSTAT® A : Your professional start in cell cultivation and microbial fermentation

Featuring a compact footprint, the BIOSTAT® A saves valuable space in your laboratory.

Simple and Automatic Aeration Control

The new aeration system of the BIOSTAT® A provides continuous automatic flow control over the full range of each gas used. As a result, BIOSTAT® A does not require any manual adjustment of flow meters and therefore eliminates problems with pulsed aeration. Setting up the bioreactor for use is straightforward: Just connect the aeration tubing, configure the aeration profile, enter the DO setpoint – that''s it!

For cell culture applications, interfaces for four gases (air, O2, CO2 and N2) are available for DO and pH control. The microbial version features two gas lines (air and O2) for DO control.

Glass and Single-use for More Flexibility – Every Day

The BIOSTAT® A is available with single-wall glass vessels in a choice of working volumes of 1, 2 or 5 liters maximum. Whether you select our reusable UniVessel® Glass version or our disposable UniVessel® SU unit with a maximum 2-liter working volume, you can use the same system controller.

Both the UniVessel® Glass and the UniVessel® SU feature the classic stirred-tank design to give you comparable results. The advantage: The same motor drives the stirrer of both vessels so you can easily change over from reusable to single-use or vice versa.
