CN202133562U - Small-quantity sampling tool in laboratory - Google Patents

Abstract

The utility model relates to a small-quantity sampling tool in a laboratory, which is characterized by being formed by bending a stainless steel wire with the diameter ranging from 2mm to 3mm. One end of the steel wire is pressed to be a flat-spade-shaped head portion, and the other end of the steel wire is bended to be a handle. Compared with the prior art, the small-quantity sampling tool has the advantages of being accurate in sampling, convenient, quick, capable of being reused, easy to clean and free of cross contamination when a small quantity of coke chemicals with corrosivity, crystallization performance or thick performance or intermediate products are sampled.

Description

The a small amount of sampling instrument of a kind of testing laboratory

Technical field

The utility model relates to field, Coal Chemical Industry laboratory, relates in particular to a small amount of sampling instrument of a kind of testing laboratory.

Background technology

In the Coal Chemical Industry laboratory, often need do stratographic analysis to some coke chemicals or middle article sample with corrosivity, crystallization or thickness; When needs are got the following sample of 1g; Common sampling instrument can not accurately be taken a sample; And be difficult for to clean, be prone to cause cross pollution, press for a kind of corrosion-resistant, convenient and swift, can reusable sampling instrument.

Summary of the invention

The purpose of the utility model provides a small amount of sampling instrument of a kind of testing laboratory, solves the coke chemicals or a small amount of problem of sampling of middle article sample of corrosivity, crystallization or thickness.

For solving the problems of the technologies described above, the technical scheme of the utility model is:

The a small amount of sampling instrument of a kind of testing laboratory adopts diameter 2～3mm stainless steel steel wire to bend and forms, and an end is pressed into flat chisel shape head, and the other end curves handle.

Compared with prior art, the beneficial effect of the utility model is: get have corrosivity, when the coke chemicals of crystallization or thickness or middle article small sample, it is accurate, convenient and swift take a sample, have can reuse, the advantage of easy cleaning, no cross pollution.

Embodiment

Be described further below in conjunction with the embodiment of accompanying drawing the utility model:

Seeing Fig. 1, Fig. 2, is a kind of testing laboratory of the utility model a small amount of sampling instrument example structure synoptic diagram, adopts diameter 2～3mm stainless steel steel wire 1 to bend and forms, and an end is pressed into flat chisel shape head 2, and the other end curves handle 3.

In the use, when getting crystalline mixture class sample, with the sample heat fused; Use sampling instrument that sample is stirred earlier, propose sampling instrument fast, splash in the sampling bottle being trapped in a terminal sample of sampling instrument; After adding thinning agent, can analyze.

When getting pure substance crystal class sample, can utilize this sampling instrument, firmly dig out the crystallization sample.

When getting liquor sample, utilize this instrument that sample is stirred earlier, sampling instrument is proposed fast, splash in the sampling bottle being trapped in a terminal sample of sampling instrument, behind the adding thinning agent, can analyze.

Claims (1)

1. a small amount of sampling instrument of testing laboratory is characterized in that, adopts diameter 2～3mm stainless steel steel wire to bend and forms, and an end is pressed into flat chisel shape head, and the other end curves handle.
