Abstract
The invention relates to a test tube rack for complete transfer of liquid. The test tube rack is characterized by comprising an upper plate of the test tube rack, a connecting column of the test tube rack, a guide plate of the test tube rack, an elastic buffer cushion and a bottom plate of the test tube rack, wherein the upper plate of the test tube rack, the guide plate of the test tube rack, the elastic buffer cushion and the bottom plate of the test tube rack are sequentially connected with the connecting column of the test tube rack from top to bottom; the upper plate of the test tube rack and the guide plate of the test tube rack are arranged in a spacing way; the guide plate of the test tube rack, the elastic buffer cushion and the bottom plate of the test tube rack are sequentially abutted and connected; a plurality of through holes are correspondingly formed in the upper plate of the test tube rack and the guide plate of the test tube rack; the through holes in the upper plate of the test tube rack and the guide plate of the test tube rack are matched with the elastic buffer cushion to form a containing space for holding a sample test tube; the elastic buffer cushion can form the bottom part of the containing space. The test tube rack has the advantages that the puncturing of the test tube by a delivered needle is effectively prevented, the complete transfer of sample liquid in the test tube is realized, and the defects of low accuracy of an analysis result and waste of the sample are overcome.
Description
Technical field
The present invention relates to a kind of test tube rack, more particularly, to a kind of test tube rack being easy to liquid transfer completely.
Background technology
Sample introduction needle sampling is the sampling technique that analytical tool is most frequently with, and drives metal sample introduction needle to enter generally by motor
Enter sample tube pipette samples.This sample introduction needle sampling technique has sample introduction needle contact sample tube bottom and sample introduction needle with liquid level
Two kinds of sampling modes of fall.What sample introduction needle contacted the sampling mode of sample tube bottom it is critical only that sample introduction needle needle point and test tube bottom
Laminating, but in order to prevent sample introduction needle from poking test tube, need to make sample introduction needle keep certain gap, therefore test tube with test tube bottom
In sample be unable to reach and shift completely, lead to the accuracy of ultimate analysis result to decline.And sample introduction needle is with taking that liquid level declines
It is fixing that sample loading mode needs the sample volume preparing, and general all far more than actually required sampling volume, therefore this
The mode of kind undoubtedly can waste sample, also cannot realize the transfer completely of sample in test tube simultaneously.
Content of the invention
The main object of the present invention is to provide one kind both can effectively prevent sample introduction needle from poking test tube, may be easy to instrument again
The test tube rack device of complete transfer liquid.
The purpose of the present invention can be reached by adopting the following technical scheme that：A kind of test tube being easy to liquid transfer completely
Frame, including test tube rack upper plate, test tube rack connecting post, test tube rack guide plate, elastic buffering pad and test tube rack base plate, described test tube rack
Upper plate, test tube rack guide plate, elastic buffering pad and test tube rack base plate are from top to bottom connected in turn in described test tube rack connecting post,
Described test tube rack upper plate and described test tube rack guide plate are interval setting, described test tube rack guide plate, elastic buffering pad and test tube
Frame base plate order offsets connection；Described test tube rack upper plate and test tube rack guide plate are also provided with correspondingly multiple logical
Hole, the described through hole on described test tube rack upper plate and test tube rack guide plate is matched with described elastic buffering pad, to constitute placement
The accommodation space of sample tube, described elastic buffering pad constitutes the bottom of described accommodation space；It is characterized in that, described elasticity is slow
Punching pad is made using high resiliency latex.
Described test tube rack upper plate, test tube rack connecting post, test tube rack guide plate, test tube rack base plate all have the stainless of 304 materials
Steel is made, and is welded using argon arc welding technology.
The Advantageous Effects of the present invention：The present invention contacts sample tube bottom using setting elastic buffering pad with sample introduction needle
Sample the mode that combines, can effectively prevent sample introduction needle from poking test tube it is achieved that in test tube sample liquids transfer completely, from
And avoid analysis result accuracy and reduce the shortcoming with sample waste.
Brief description
Fig. 1 is the structural representation of the present invention；
In figure：1- test tube rack upper plate, 2- test tube rack connecting post, 3- test tube rack guide plate, 4- elastic buffering pad, 5- test tube rack
Base plate.
Specific embodiment
For making those skilled in the art more understand and clear and definite technical scheme, with reference to embodiment and accompanying drawing
The present invention is described in further detail, but embodiments of the present invention not limited to this.
As Fig. 1, a kind of test tube rack device being easy to liquid transfer completely that the present invention provides, it include test tube rack upper plate 1,
Test tube rack connecting post 2, test tube rack guide plate 3, elastic buffering pad 4 and test tube rack base plate 5, test tube rack upper plate 1, test tube rack guide plate
3rd, elastic buffering pad 4 and test tube rack base plate 5 are from top to bottom connected in turn in test tube rack connecting post 2, and test tube rack upper plate 1 and examination
Pipe support guide plate 3 is interval setting, and test tube rack guide plate 3, elastic buffering pad 4 and test tube rack base plate 5 then sequentially offset connection.
Meanwhile, multiple through holes, test tube rack upper plate 1 and examination are also provided with correspondingly on test tube rack upper plate 1 and test tube rack guide plate 3
Through hole on pipe support guide plate 3 is matched with elastic buffering pad 4, and to constitute the accommodation space placing sample tube, and elasticity is slow
Rush the bottom that pad 4 constitutes this accommodation space.Elastic buffering pad 4 is larger and can to recover elastic deformation ability stronger using elastic deformation
Nonmetallic materials make, such as high resiliency latex.
When using, sample tube is placed on through hole and elasticity on test tube rack upper plate 1 and test tube rack guide plate 3 to the present invention
In the accommodation space that cushion pad 4 is constituted, the bottom of sample tube is contacted with elastic buffering pad 4.When sample introduction needle enters sample examination
During pipe pipette samples liquid, due to the elastically-deformable performance of bottom resilient cushion pad 4, the pressure that sample tube bottom is subject to is by bullet
Property cushion pad 4 absorbs, and can effectively prevent sample tube bottom from being poked so that sample introduction needle can by sample introduction needle because pressure is excessive
To fit tightly the bottom of sample tube, thus completely eliminating gap between sample introduction needle and sample tube bottom it is ensured that sample
Liquid in product test tube is shifted completely, it is to avoid the shortcoming that sample waste and analysis result accuracy reduce.
The above is only the preferred embodiment of the present invention it is noted that common skill for the art
For art personnel, under the premise without departing from the principles of the invention, some improvement can also be made and modify, these improve and modify
Also should be regarded as protection scope of the present invention.
