The present invention provides a high speed homogenizer which has an adjustable gripping means to grip and hold containers of varying size. This gripping and holding means can be centered or decentered under the homogenizing tool. Decentering a container held by the gripping and holding means tends to minimize or even eliminate vortexing problems. The homogenizer also has electronic means for controlling the speed and time of operation of the homogenizing tool. The electronic control means of the homogenizer can also monitor the temperature of the sample being homogenized and respond to changes in temperature when necessary. The homogenizer can be easily adjusted up and down a vertical support post by a counter weighting mechanism such as a constant force spring.

A status display for a hardware modeler includes an LCD panel which is divided into regions corresponding to cartridge banks and each region is further divided into sections corresponding to individual cartridges. The sections display relevant identifying information for its associated cartridge. If the cartridge is currently active, that information is shown in reverse video to indicate that the cartridge is active. The modeler can be paused by pressing a pause switch. The modeler's processor then inhibits activity of inactive cartridges and, at the next opportunity, inhibits activity of active cartridges so that the cartridges can be rearranged, etc. The status of the modeler as a whole is also displayed.
