Embodiment Construction

[0016] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments. The given embodiments are only general illustrations of the products or methods of the present invention, which help to better understand the present invention, but do not limit the scope of the present invention. The experimental methods described in the following examples, unless otherwise specified, are conventional methods; the materials, unless otherwise specified, can be obtained from commercial sources.

[0017] see figure 1 , a multi-channel liquid sampler of the present invention, its main structure includes a supporting frame, a lifting platform 2 installed on the frame and a sample adding device arranged on the lifting platform 2, the The sample loading device is in different positions when the lifting platform 2 moves up and down on the frame body to realize liquid sample feeding, when the sample feeding is finished and other states.

Abstract

The invention discloses a multichannel liquid sample injector which comprises a rack body, a lifting table and a sampling device, wherein the rack body comprises a bottom plate and a pair of support pillars which are symmetrically arranged on the bottom plate; the pair of support pillars respectively pass through holes formed in the lifting table, so that the lifting table can move up and down along the support pillars, and is fixed on the support pillars by lifting locking knobs arranged on the lifting table; the sampling device comprises a funnel-shaped liquid storage groove and an inverted T-shaped liquid discharge channel, wherein the top of the inverted T-shaped liquid discharge channel is communicated with a close up end of the liquid storage groove; a liquid discharge switch is arranged at the part of the liquid storage groove, which is close to the close up end; the bottom of the inverted T-shaped liquid discharge channel is provided with a plurality of sampling needles; and each sampling needle passes through the lifting table and is fixed on the lifting table. The multichannel liquid sample injector can be used for sampling liquid sample into multiple channels at the same time, thus being time-saving and labor-saving, reducing the error and the error probability, and being especially suitable for sampling liquid in a centrifuge tube; and two switches are arranged on the multichannel liquid sample injector, so that the liquid sampling flow speed is effectively controlled, and the different liquids are avoided being mixed when being added into the same tube.

Description

technical field [0001] The invention relates to a sampler, in particular to a sampler with multiple sampler channels and suitable for liquid sampler. Background technique [0002] As we all know, in the experimental process in the fields of cell biology, molecular biology, microbiology, etc., it is generally necessary to use tubular containers such as test tubes or centrifuge tubes to participate in the experiment, especially when using centrifuge tubes for density gradient centrifugation, the medium is usually used first. A continuous or discontinuous density gradient solution is formed in the centrifuge tube. The medium is generally cesium chloride, sucrose or polysucrose, and then the broken cell suspension or homogenate is placed on the top of the medium, and it is made by gravity or centrifugal force field. Cells are layered and separated. During this operation, first add the above-mentioned medium to the bottom of the centrifuge tube, and then carefully and slowly add...
