Abstract
A mechanical triturator for biological material comprises a cylindrical housing defining a chamber in which a cutting member constituted by a perforated plate is disposed. A rotor member, mounted for rotation in the chamber, has a screw which cooperates with the cutting member in order, as a result of its rotation, to supply the biological material into contact with the cutting member and to cause the trituration thereof.
Claims20
A mechanical triturator for biological materials adapted to prepare a sample of said biological material for biopsy or DNA analysis, characterised in that it comprises:
- a cylindrical housing defining a chamber,
- a cutting member in the form of a foraminous plate with holes having a dimension of from 20 to 100 .mu.m in width, which is disposed transversely in the chamber so as to define within said chamber an input portion for the supply of the material to be triturated and portion for collecting the triturated material, said cutting member having a plurality of blades surrounding each hole extending from a general plane of the plate into the input portion,
- a rotor member mounted for rotation in the chamber and having a grinding member which is fixed to the rotor and is disposed in the input portion, and cooperates with the cutting member in the order, as a result of its rotation, to supply the biological material into contact with the blades and to cause the trituration thereof.
