Embodiment Construction

[0031] exist figure 1 In an embodiment of the present invention, the apparatus of the invention comprises a base plate 10, the bottom of which is provided with spacer legs 11 for standing on the top of a bench or some other planar stationary support, and the top of the base plate 10 receives the motor through a vibration filter connection 13 12 and a support 14 for the hinge center 15.

[0032] A disc 16 fastened on the shaft of the motor 12 is provided with an eccentric pin 17 on which a coupling 19 is fastened by means of a rolling ball joint 18 .

[0033] The link 19 is fastened to the support 20 by means of a fork 22 capable of imposing on the support 20 a rotation about two mutually perpendicular axes X and Y, the intersection of the X and Y axes defining the hinge center 15.

[0034] The hinge 15 is fastened to the support 14 by bearings 24 , preferably ball bearings, which prevent axial movement and allow rotation about the axis X in a single degree of freedom.

Abstract

An appliance for rapidly vibrating test tubes containing samples to be ground up, the appliance comprising an electric motor (12) for driving rotation of a disk (16) that is provided with an eccentric pin (17), the appliance being characterized in that the test tubes (23) are perpendicular to the eccentric pin and are held by a clamp (21) mounted on a support (20) that is substantially parallel to the eccentric pin, being connected to a fixed baseplate via a Cardan type hinge (15) having two mutually perpendicular axes of rotation (X and Y), one of which axes (Y) is substantially parallel to the eccentric pin (17) and connects the support (20) to the other axis (X) of the hinge (15) that prevents the support (20) from moving in rotation about a perpendicular axis (Z). The support (20) is connected to the eccentric pin (17) by a link (19).

Description

technical field [0001] The present invention relates to a device for rapid vibration of a test tube containing a sample, especially a biological sample, the rapid vibration of the test tube being used to grind, stir and / or homogenize the sample. Background technique [0002] By encapsulating a sample into a test tube that also contains microbeads composed of glass, ceramic, steel, or other material and vibrating the sealed test tube substantially axially at a high frequency, such as at a frequency of about 100 hertz (Hz) It is known to grind biological samples (tissues, grains, hair, etc.) for shorter periods of time (eg, 30 seconds (s) to 60 s). [0003] Several documents such as US-A-5567050 and WO2004 / 012851 describe apparatus for carrying out the methods described above. The apparatus comprises a disc supporting the test tube and means for driving the disc in oscillation about a center of rotation. [0004] The test tubes are fastened to the periphery of the disc at th...
