Sample homogeniser
First Claim
1. :
- An homogeniser for comminuting a sample of material comprising a container (1), and a grinder (20), wherein the container (1) comprises an interior (2) defined by sidewalls (3), an upper portion (4) having an upwardly open top communicable with an exterior of the container, and an interior bottom (5), and the grinder (20) comprises (i) a hollow shaft (22) locatable within the container, the hollow shaft (22) defining an interior channel (23), (ii) a grinding head (21) defining a closed end of the shaft (22), (iii) at least one port (24) located on the elongate sides of the shaft (22) said port being dimensioned so that only comminuted material may flow into the interior channel (23), of the shaft (22).

Abstract
An apparatus for comminuting or homogenising biological tissue, comprising a container (1) with an interior bottom (5) comprised of an abrasive surface (6) a cap (10), and a grinder (20) receivable in the interior (2) of the container (1). Wherein the grinder (20) comprises a grinding head (21) and a cylindrical shaft (22) having an interior channel (23) defined therein; and at least one port (24) in the cylindrical shaft (22) through which comminuted material may flow into the interior channel (23), of the cylindrical shaft (22). The interior channel (23) of the cylindrical shaft (22) may communicate with the exterior of the container (1) so that the comminuted or homogenised sample that has passed through the port(s) (24) of the cylindrical shaft (22) may be removed from apparatus. In one embodiment the comminuted or homogenised sample is removed by aspiration.
