The ?-24 bioreactor from Applikon offers a platform for fermentation in a very small volume. Based on a micro-titerplate (24 wells), each well (reactor) has a working volume of 2–6 mL. Each reactor has its own pH and temperature measurement and control capabilities. The agitation (orbital shaking) can be controlled in the range 0–800 rpm. The bioreactor is completely automated and all data (per reactor) are visible on the screen of a PC and stored. Applikon Inc., 650.578.1396, www.applikon.com.
