In order to choose the optimal products for a particular application, please review the following selection process thoroughly to determine which products best suit a specific need. Follow the volume ranges as specified for each Omni motor and accessory in order to choose the optimal system for the specific sample and volumes being processed. If the sample is viscous, then the volume ranges listed no longer apply. Instead, choose a generator probe one or two sizes larger than what the listed volume ranges indicate, while ensuring that the generator probe is not larger than the inside diameter of the vessel used. The liquid or soft tissue samples can be processed easily with a flat bottom generator probe in whatever size the volume calls for.
Larger samples call for larger generator probes.
Fibrous samples which are harder to tear call for saw tooth generator probes. If a solid sample is being processed, the inside diameter of the generator probe chosen must be twice that of the largest piece of sample and oversized windows are also recommended. If the size of the solid exceeds one half the diameter of the generator probe, then the sample will not be able to enter the processing area in the generator probe and no contact will be made with the shearing rotor blade. Samples that are difficult to turn require more torque and should be processed with a 2.4HP motor. Viscous samples will also need larger generator probes to overcome the viscosity resistance.
