Waste disposers are a sub-group of rotor-stator type homogenizers.  A rapidly rotating platform turning at high speed (the "rotor") forces biomaterial through a non-moving stainless steel sleeve containing an array of slits or holes (the "stator") where it is sheared and cut into tiny pieces.  While a standard waste disposer process biomaterial in a single pass through the disposer's elements, BioSpec has greatly improved the homogenization process by the addition of an external recycling loop on the machine and a large stainless steel receiving container.

Unlike most lab homogenizers, the SemiContinous Tissue Disperser requires little sample preparation, such as cutting, chopping or trimming, prior to homogenization and can quickly homogenize kilogram quantities of tissue in less than a minute.  The unit handles almost any kind of soft or flexable biomaterial - even homogenizing an intact mouse carcass...skin, bones and all!
