Abstract

The invention discloses a multipoint equidistant adjusting device. The device comprises a left baffle and a right baffle, and a cylinder body is fixedly connected between the left baffle and the rightbaffle; conductive springs are arranged in the cylinder body; the left ends of the conductive springs are fixedly connected with a first limiting block, a first limiting groove slidably connected with the first limiting block is formed in the inner wall of the cylinder body, the right ends of the conductive springs are fixedly connected with the right baffle, the conductive springs are electrically connected with a built-in power source through a potentiometer, and the number of the conductive springs is multiple. The device has the advantages that the cylinder body, the first limiting block,the first limiting groove, a second limiting block, a second limiting groove, the conductive springs and a variable resistance device are arranged, and the resistance of the potentiometer is adjustedaccording to specific conditions, so that the current intensity in a circuit formed by the potentiometer, the conductive springs and the built-in power supply is changed, the contraction degree of the conductive springs, the distance between every two circles of conductive springs and the distance between the multiple liquid taking needles are changed, and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of biological experiments, in particular to a multi-point equidistant adjustment device. Background technique [0002] In the field of biological experiments, it is often necessary to use a pipetting device to transfer a certain volume of experimental solution. Current pipetting devices include single-channel and multi-channel. When using a multi-channel pipetting device to suck and push out the experimental solution, sometimes it is necessary to adjust the equidistant distance of multiple pipetting needles. The existing pipetting device uses multiple driving devices to adjust the distance between multiple pipetting needles, which is cumbersome and has errors. [0003] In order to solve the above problems, we propose a multi-point equidistant adjustment device. Contents of the invention [0004] The object of the present invention is to propose a multi-point equidistant adjustment device in order to sol...
