Sample container heating device for nucleic acid extraction equipment and nucleic acid extraction equipment

Abstract

The invention discloses a sample container heating device for nucleic acid extraction equipment, and further provides the nucleic acid extraction equipment. The sample container heating device includes a fixed plate. An electric heating plate is arranged on the inner wall of the fixed plate in an embedded mode, and a fan is fixedly connected to the upper end of the fixed plate. A spiral ventilation tube is arranged in an embedded mode at the position, on the periphery of the electric heating plate, of the fixed plate in an embedded mode. The input end of the spiral ventilation tube is connected with the output end of the fan, and a device cavity is formed in the side wall of the fixed plate. The nucleic acid extraction equipment includes a base, a vertical plate and the sample container heating device for the nucleic acid extraction equipment according to any one of claims 1-2. A groove is formed in the side wall of the vertical plate. The sample container heating device can adjust thespeed voluntarily according to the temperature of a nucleic acid extraction raw material, so that the electricity utilization is more scientific, the energy consumption is lower, the sample containerheating device is more in line with modern standards for environmental protection and energy conservation, and the rotation speed is low and nucleic acid cannot be destroyed.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a sample container heating device for nucleic acid extraction equipment and nucleic acid extraction equipment.

[0003] Patent No. CN201720698116.6 proposes a sample container heating device for nucleic acid extraction equipment and nucleic acid extraction equipment. The heating device for the sample container is used to directly heat the nucleic acid raw material, which can easily lead to local heating and damage of the nucleic acid. Part of the heating equipment improves the heating efficiency by stirring the raw materials, but the rapid stirring is easy to break the nucleic acid, which is difficult to control
