Abstract
An auxiliary holder of tubes intended for disintegration of living cells, such as yeast cells, in the presence of glass beads, as well as for mixing substances and pellet resuspension. The holder is installed on a vibrator. Due to specially-made gaps between the tubes and the main parts of the holder the processed cells and substances are subjected to a complex impact of vibration created by the vibrator and shocks created by the holder. The holder strongly enhances the effectiveness of the vibrator. During the disintegrating process the presence of a researcher is not required.
Claims20
A tube holder for holding at least one tube, the holder comprising:
- a shaft having means for coupling the shaft to a vibrator;
- a driving member coupled to the shaft and including at least one first hole through which a first portion of the tube can pass, the hole being shaped such that the tube is engaged by the driving member at least while the driving member is vibrated by the shaft;
- and
- a shocking-member spaced from the driving member along the length of the tube shaped to be moveable with respect to the shaft, the shocking member including at least one second hole through which a second portion of the tube can pass, the second hole being larger in cross-section than the tube and sized so that as the tube is vibrated by the driving member, the tube may impact on the shocking member.
The tube holder of aim 1, wherein the first hole is sized larger in cross section than the first portion of the tube to produce a gap between the driving member and the first portion of the tube and the first hole is small enough in cross section that the driving member may vibrate the tube.
A tube holder for a plurality of flanged tubes for disintegrating living cells, mixing substances, and pellet resuspension by vibration, comprising:
- a shaft, a driving wheel, and a shocking wheel;
- the shaft having a shoulder;
- means for affixing the shaft to a vibrator;
- the driving wheel being coupled to the shaft, the driving wheel having a plurality of peripheral holes the tubes can pass through, wherein the diameter of the peripheral holes is larger than the diameter of the tubes at the point the tubes pass through the holes, producing a gap between each tube and the driving wheel, the diameter of the peripheral holes of the driving wheel is less than the diameter of the flanges of the tubes, so that the tubes rest upon the driving wheel;
- the shocking wheel resting upon the shoulder of the shaft a distance from the driving wheel which is less than the length of the tubes, the shocking wheel having a central hole the diameter of which is larger than the diameter of the shaft above the shoulder and less than the diameter of the shoulder, producing a gap between the shaft and the shocking wheel and so that the shocking wheel is free to move relative to the shaft, the shocking wheel having a plurality of peripheral holes which correspond to the holes of the driving wheel, wherein the diameter of the peripheral holes of the shocking wheel is larger than the diameter of the tubes at the point the tubes pass through the holes, producing a gap between each tube and the shocking wheel.
