A modified, top-of-the-line domestic waste disposer that has been
modified to sit operate top of the lab bench - ready to be plugged into a
110 volt power socket. Closed-loop plumbing has been installed on the
basic unit to permit recycling the tissue sample contents.

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 Semi-Continous 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 flexible biomaterial - even homogenizing an intact mouse, bones and all!
