Abstract
The utility model provides a sxemiquantitative sampling device which characterized in that the device comprises sampler and handle, the sampler be well empty cylindrical shape, the upper end opening, its lateral wall upper portion is equipped with the open slot, the lower bottom surface of sampler is equipped with an internal screw thread regulation hole, the handle constitutes by circular shape ration piece and fixed connection's regulation pole with it, the ration piece is located the cavity of sampler, the one end of adjusting the ration piece that the pole is close to is equipped with adjusts the screw thread with regulation hole matched with, the outside that the regulation pole other end passed the regulation hole and stretched out the sampler. The utility model relates to a rationally, simple structure uses the device to overcome traditional dispensing spoon storage appearance recess and can't measure defects such as sample volume, the sample volume is uncertain, storage appearance groove size can not be adjusted, the efficiency of sampling precision, accelerated sample speed, the precise and quantitative process such as weighed 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 technical fields such as the sampling during micro-example subpackage, weighing, or semiquantitative little power sample.
Background technology
The weighing of micro-example is operation sequence important during experimental analysis and sample subpackage, and required precision is high, and work efficiency is relatively low, and task dullness is heavy, usually the rate-limiting step in analytical methods.During current sample weighs, commonly used sample is dimple form key, and a general key kit is divided into a lot of, is suitable for the sample weighing of different quality number of levels respectively.Operating process has the disadvantages that 1) do not fix sample and take up volume, also cannot measure sample volume, be difficult to grasp each quantity of sampling quantity, i.e. sampling amount uncertain, repeatedly add during thus resulting in weighing or return etc. operates, and increases complexity and the step claiming sample；2) sample storage groove size is unadjustable, and i.e. 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, currently used sample spoon is inefficient during using, and does not have the function of quantitative sampling, it is impossible to the volume that regulation sample takes up, it is impossible to quantitative sampling.
Summary of the invention
For above-mentioned technical problem present in background technology, it is an object of the invention to provide a kind of sxemiquantitative sampler.
The technical solution adopted in the utility model is as follows:
A kind of sxemiquantitative sampler, it is characterised in that this device is made up of sampler and handle, and described sampler is hollow cylindrical, upper end open, and its side wall upper part is provided with open slot, the bottom surface of sampler is provided with the adjustment hole of tool female thread；Described handle is made up of the adjusting rod of circular quantification tablet and connection fixed thereto, quantification tablet is positioned at the cavity of sampler, the one end of the quantification tablet that adjusting rod is close is provided with the regulation screw thread matched with adjustment hole, and the adjusting rod other end passes adjustment hole and reaches the outside of sampler.
Described a kind of sxemiquantitative sampler, it is characterised in that: the sidewall of described sampler is provided with scale.
Described a kind of sxemiquantitative sampler, it is characterised in that: the internal diameter of described proportional sampling device is 3 mm, a length of 25 mm, a diameter of 2 mm of adjusting rod, a length of 100 mm, the A/F of open slot is the 1/6 of sampler girth, a diameter of 3 mm of quantification tablet.
Described a kind of sxemiquantitative sampler, it is characterised in that: the external diameter of described quantitative regulation screw thread, equal to the internal diameter of adjustment hole, is 2 mm.
Compared with prior art, the trace sxemiquantitative sampler designed by this utility model, have the advantages that reasonable in design, simple in construction, scalable sample bin size, has relatively-stationary sample bin volume, and sample bin has preferable volume quantitative effect to sample.Overcome tradition 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 of the accurate quantification processes such as weighing.
