Abstract
The invention provides a semi-quantitative sampling device. The device is characterized by being composed of a sampling device and a handle, wherein the sampling device is in a hollow cylindrical shape and an opening is formed in the upper end of the sampling device; an opening groove is formed in the upper part of a side wall of the sampling device; an adjusting hole with an inner thread is formed in the lower bottom surface of the sampling device; the handle is composed of a circular quantitative sheet and an adjusting rod which is fixedly connected with the quantitative sheet; the quantitative sheet is located in a cavity of the sampling device; an adjusting thread, matched with the adjusting hole, is formed in one end, close to the quantitative sheet, of the adjusting rod; and the other end of the adjusting rod passes through the adjusting hole and stretches out of the outer side of the sampling device. The semi-quantitative sampling device is reasonable in design and simple in structure; with the adoption of the device, defects of a traditional medicine spoon type sample storage groove that the size of samples cannot be metered, a sampling amount is uncertain, the size of the sample storage groove cannot be adjusted and the like are overcome; and the sampling precision is improved, the sampling is accelerated, and the efficiency of accurate quantitative processes including weighing and the like is improved.
Description
Technical field
The present invention relates to a kind of sxemiquantitative sampler, be specifically related to a kind of spoon, be mainly used in the sampling in micro-example packing, weighing process, or the technical field such as semiquantitative little power sample.
Background technology
The weighing of micro-example is that experimental analysis and sample divide operational sequence important in process of assembling, and accuracy requirement is high, and work efficiency is lower, and task dullness is heavy, is generally the rate-limiting step in analytical methods.The sample that current sample generally adopts in weighing is dimple form key, and a general key kit is divided into only a lot, is suitable for other sample weighing of the different quality order of magnitude respectively.There is following shortcoming: 1) do not have fixed sample to take up volume in operating process, also cannot measure sample volume, not easily grasp each quantity of sampling quantity, namely sampling amount is uncertain, therefore cause the operation such as interpolation or return repeatedly in weighing process, increase the complexity and step that sample; 2) sample storage groove size is unadjustable, and namely to take up sample volume immutable for spoon, need different model spoon with the use of, increase the complexity of operating process, reduce the efficiency that the later stage weighs; 3) a set of spoon is more, inconvenience management.In a word, in the sample spoon use procedure of current use, efficiency is lower, does not have the function of quantitative sampling, can not regulate the volume that sample takes up, can not quantitative sampling.
Summary of the invention
For the above-mentioned technical matters existed in background technology, the object of this invention is to provide a kind of sxemiquantitative sampler.
The technical solution used in the present invention is as follows:
A kind of sxemiquantitative sampler, it is characterized in that this device is made up of sampler and handle, described sampler is hollow cylindrical, upper end open, and its side wall upper part is provided with open slot, and the bottom surface of sampler is provided with the adjustment hole of tool internal thread; Described handle is made up of with the adjuster bar be fixedly connected with it the quantification tablet of circle, quantification tablet is positioned at the cavity of sampler, the one end of the quantification tablet that adjuster bar is close is provided with the adjustment screw thread matched with adjustment hole, and the adjuster bar other end passes adjustment hole and reaches the outside of sampler.
Described a kind of sxemiquantitative sampler, is characterized in that: the sidewall of described sampler is provided with scale.
Described a kind of sxemiquantitative sampler, is characterized in that: the internal diameter of described proportional sampling device is 3mm, and length is 25mm, and the diameter of adjuster bar is 2mm, and length is 100mm, and the A/F of open slot is 1/6 of sampler girth, and the diameter of quantification tablet is 3mm.
Described a kind of sxemiquantitative sampler, is characterized in that: the external diameter of described quantitative adjustment screw thread equals the internal diameter of adjustment hole, is 2mm.
Compared with prior art, the micro-sxemiquantitative sampler designed by the present invention, has following beneficial effect: reasonable in design, structure is simple, adjustable sample bin size, has relatively-stationary sample bin volume, and sample bin has good volume quantitative effect to sample.Overcome traditional spoon sample storage groove and cannot measure the defects such as sample volume, sampling amount is uncertain, sample storage groove size is unadjustable; Improve sampling precision, accelerate sample rate, improve the efficiency that weighing waits accurate quantification process.
