Abstract
The invention discloses a microscale sampling rod, comprising a rod body made of a hydrophilic material. One end of the rod body is a sampling end formed with a groove. According to the technical scheme, the sampling end of the rod body is provided with the groove, which soaks liquid drops by relying on the surface tension of the liquid; and when the groove volume is determined, a removal amount is basically accurate. The microscale sampling rod has advantages of one-time use, convenient operation, accurate removal amount and low production cost.
Description
Technical field
The present invention relates to a kind of microsampling rod.
Background technology
In clinical and scientific research experiment fields such as tissue cultivation, bacteriology, need measuring device accurately to pipette the solution of certain volume.Adopt pipette can pipette the liquid that minimum volume is 1000 microlitre to 5000 microlitres, and pipetting for micro liquid (1 microlitre to 50 microlitre), the general mode that adopts the little suction pipe of plastics to pick drop operates in the prior art, but has the problems such as the liquid volume size is uncertain, inconvenient operation that pipette.The laboratory also has the liquid-transfering gun of employing to pipette micro liquid, but inconvenient operation is not suitable for fast sampling and diagnosis.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of easy to use, amount of pipetting accurately, the microsampling rod of low cost of manufacture.
To achieve the above object, the present invention has adopted following technical scheme:
A kind of microsampling rod comprises the barred body of being made by water wetted material, and barred body one end is formed with groove for sampling end, sampling end.
As preferably, it is bowl-shape that described sampling end is ball, conveniently picks drop and save material.
As preferably, the volume of described groove is 1 microlitre to 50 microlitre.
As preferably, be formed with on the described barred body many protruding stupefied, make things convenient for the hand crawl.
The present invention is owing to having adopted above technical scheme, barred body sampling end arranges groove, relies on the surface tension of liquid to pick drop, after the groove volume is determined, the amount of pipetting is substantially accurate, have disposable use, easy to operate, the amount of pipetting accurately, the advantages such as low cost of manufacture.

Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is made a detailed explanation.
Embodiment 1:
Such as Fig. 1, Fig. 2, a kind of microsampling rod shown in Figure 3, comprise the barred body 1 of being made by the hydrophilic polyesters material, barred body 1 one ends are formed with groove 21 for sampling end 2, sampling end 2.It is bowl-shape that described sampling end 2 is ball.The volume of described groove 21 is 1 microlitre to 50 microlitre.Be formed with four protruding stupefied 3 on the described barred body 1.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
