Glass rod timing heating device

Abstract

The invention provides a glass rod timing heating device which comprises a clamping unit and a supporting platform which are fixedly arranged in sequence from top to bottom, wherein the clamping unitcomprises a rotating shaft, and a clamping body is fixedly arranged at one end of the rotating shaft; a containing cavity is formed in the supporting platform. A supporting block capable of moving upand down is arranged above the supporting platform; a supporting pipe with the top end sealed is connected below the supporting block, the supporting pipe and the supporting block synchronously move in the vertical direction, a supporting spring is arranged in the supporting pipe, the lower end of the supporting pipe penetrates through the supporting platform and is arranged in the containing cavity, one end of the supporting spring abuts against the top of the supporting pipe, and the other end of the supporting spring abuts against the bottom of the containing cavity; a locking unit is further arranged in the containing cavity and comprises a spring bolt, a locking hole is formed in the top of the supporting pipe, and when the supporting pipe is arranged at the lower limit position, thespring bolt can be inserted into the locking hole. The supporting unit capable of moving up and down is adopted to lift up the glass rod, so that the glass rod is separated from flame, the locking unit is adopted to control the supporting unit, and the supporting unit is prevented from being lifted up when heating is not completed.

Description

technical field [0001] The invention belongs to the field of biological research equipment, in particular to a glass rod timing heating device. Background technique [0002] In the process of biological research, it is often necessary to separate biological cells through a glass rod. Before the glass rod is used, it is usually necessary to heat and stretch the glass rod to make the end of the glass rod thinner, so that the thinned glass rod can be used Isolate the desired cells; [0003] In the process of heating the glass rod, due to the different specifications of the glass rod, the scheduled heating time of the glass rod varies from 2 to 5 seconds. Short, the glass rod softens quickly when heated on the flame, which makes it inconvenient to watch the timing mechanism during the heating process, but can only rely on experience to measure the heating time, resulting in deviations in the heating time of the glass rod, making the heating time of the glass rod Inconsistent w...

[0003] In the process of heating the glass rod, due to the different specifications of the glass rod, the scheduled heating time of the glass rod varies from 2 to 5 seconds. Short, the glass rod softens faster when heated on the flame, which makes it inconvenient to watch the timing mechanism during the heating process, but can only rely on experience to measure the heating time, resulting in deviations in the heating time of the glass rod, making the heating time of the glass rod Inconsistent with the preset time, the glass rod is stretched too thin or too thick during the process of stretching the glass rod, which is not convenient for cell separation
