Linear reciprocating shaking table device for nucleic acid extraction

Abstract

A linear reciprocating rocker apparatus for nucleic acid extraction mainly comprises a platform and a drive unit integrated with the platform. The platform has a sample tray on its surface and an inclined groove on its bottom surface. The drive unit is located below the platform and is pivotally connected to a cam, which is positioned in the inclined groove. The drive unit drives the cam to rotate in the inclined groove, and the relative action between the cam and the inclined groove causes the platform to perform linear reciprocating motion for nucleic acid extraction. This allows the sample to move linearly along a fixed trajectory during nucleic acid extraction, positioning and stopping at a fixed position, resulting in a more uniform and stable energy distribution. This avoids the energy dispersion problem caused by centrifugal force during rotational motion, thereby improving cell disruption efficiency and optimizing the overall performance of nucleic acid extraction.

Claims

1. A linear reciprocating shaking table device for nucleic acid extraction, comprising: a platform having a sample tray on its surface for placing nucleic acid extraction samples, and an inclined groove at an appropriate position on its bottom surface; a driving member disposed below the platform, which is pivotally connected to a cam, such that the cam is positioned in the inclined groove, so that when the cam rotates in the inclined groove, the eccentric action of the cam drives the platform to perform linear reciprocating motion, causing the sample to move linearly along a fixed trajectory and to be positioned and stopped at a fixed position, thereby making the energy distribution more uniform and stable, thereby improving the cell disruption efficiency and optimizing the overall efficiency of nucleic acid extraction.

2. The linear reciprocating rocking table apparatus for nucleic acid extraction as described in claim 1, wherein, The sample tray is equipped with multiple positioning slots for clamping and positioning multiple nucleic acid extraction samples.

3. The linear reciprocating rocking table apparatus for nucleic acid extraction as described in claim 1, wherein, The inclined chute is set at an appropriate angle from the front to the rear of the platform.

4. The linear reciprocating rocking table apparatus for nucleic acid extraction as described in claim 1, wherein, The driving component is a linear motor.

5. The linear reciprocating rocking table apparatus for nucleic acid extraction as described in claim 1, wherein, The drive unit is connected to a control module to set motion parameters such as the motion amplitude and frequency of the drive unit, thereby adjusting the operating mode of the platform.
