The St John Associates - BioTherm BioOven III Thermocycler, Model 30-202, combines quantitative procedures in a thermal cycler now by employing a unique rotating sample tray that exposes all samples to the same environment. Medical-grade temperature probes precisely match the environment of your samples. The temperature you read (which drives the response of the controller) is identical to that of your sample. The BioOven III controller is menu-driven. You can instantly find and run stored procedures. Creating new procedures or changing current ones is easier than ever before. At a glance, the display screen gives you all the information you need: sample and target temperature, name of the program or profile being run, total cycle count in the program, current cycle count and elapsed time of the experiment. The BioOven III lets you write POINTS, PROFILES, and PROGRAMS. POINTS are single temperatures and associated soak times. PROFILES are a set of up to twenty points. PROGRAMS are series of up to twenty profiles. Linking profiles and writing complex procedures has never been easier. Automatic increases or decreases in temperature or time per cycle are easily programmed as well.
