A console shaker which includes a shaker device mounted within a temperature and lighting controlled chamber and an air jacket which completely surrounds the chamber and also provides substantially laminar, HEPA-filtered air flow through the chamber in one direction. A refrigeration device and a heating device either cool or heat the air before it flows through the HEPA filter. The HEPA filter is mounted at the end of the chamber which defines an air inlet to the work chamber and an outlet is disposed at the opposite end of the chamber. The outlet end of the chamber receives air from both within the workspace of the chamber as well as from the front and rear air spaces of the air jacket. A microprocessor based control system provides an interface between the user and the various components for establishing the conditions within the chamber, such as shaker speed, temperature, time and lighting to be controlled by the user. To allow quick setting of the overall conditions or control parameters, the microprocessor based system allows one of a plurality of preset programs to be chosen by the user to set shaker speed, chamber temperature and time.
