Abstract

The utility model relates to a micro sampler assembly for rubber tree bark. The micro sampler assembly comprises a sampler with a handle. The micro sampler assembly is characterized by further comprising a steel needle; the sampler is a column body being 2mm in outside diameter and 5 to 6cm in length; the front end of the sampler is a hollow sampling end, and the rear end of the sample is fixedly connected with the handle; an axial observing groove being 1cm in length and 1mm in width is formed in one sidewall of the sampling end; the front edge of the observing groove is 1mm away from the sampling end surface; the steel needle of which the section diameter is not greater than 0.9mm is fixedly mounted on the handle.

Description

Rubber tree bark microscale sampler assembly

Technical field

The utility model relates to a kind of rubber tree bark microscale sampler assembly, especially a kind ofly extracts and special sampling instrument when other composition measurements for rubber tree bark RNA.

Background technology

In rubber tree physiological and biochemical research process; need to sample rubber tree bark; but protection test is also the basis that ensures that follow-up test can be carried out smoothly with tree as far as possible; so in the situation that guaranteeing the enough experimental measurings of sampling; should reduce the injury to gum as far as possible; for these reasons, people are in the urgent need to a kind of instrument that can extract the gum bark micro-example that can meet experiment under the prerequisite that does not injure or injure less gum as far as possible.

Utility model content

The purpose of this utility model is: need a kind of instrument that can extract the micro-gum bark sample that can meet experimental measuring under the prerequisite that does not injure or injure less gum for people, a kind of rubber tree bark microscale sampler assembly is provided.

The purpose of this utility model is achieved in that a kind of rubber tree bark microscale sampler assembly, comprise the sampler that contains handle, it is characterized in that: in sampler assembly, also comprise draw point, the external diameter 2mm of described sampler, long 5-6cm cylinder, front end is the sampling end of hollow, rear end is fixedly connected with handle, and a sidewall of sampling end is provided with axial observation groove, observes flute length 1cm, wide 1mm, observes groove forward position and sampling end face 1mm apart; Described draw point is fixedly mounted on handle, the diameter of section≤0.9mm of draw point.

In the utility model: described handle and handle are wooden handle.

Major advantage of the present utility model is: due to the external diameter 2mm of sampler, sampling process is less to bark injury; Because the sampling end of sampler is provided with observation groove, bark embeds after the sampling end of hollow, can, by observing groove intuitive judgment sampling amount, owing to being furnished with draw point, can easily the sample that embeds sampling end be peeled off to taking-up from observing groove; The utility model is simple in structure, easy to clean.

Accompanying drawing explanation

Fig. 1 is the sampler structure schematic diagram that the utility model embodiment relates to.

Fig. 2 is the structural representation of the draw point that relates to of the utility model embodiment.

In figure: 1, handle, 2, sampler, 3, sampling end, 4, draw point, 5, observe groove, 6, handle.

Embodiment

Accompanying drawing discloses the concrete structure of the utility model embodiment without limitation, below in conjunction with accompanying drawing, the utility model is further described.

As seen from Figure 1, sampler 2 of the present utility model comprises handle 1, the external diameter 2mm of sampler 2, long 5-6cm cylinder, the sampling end 3 that front end is hollow, rear end is fixedly connected with handle 1, one sidewall of sampling end 3 is provided with axial observation groove 5, observe the long 1cm of groove 5, wide 1mm, observes groove 5 forward positions and sampling end face 1mm apart;

As seen from Figure 2, described draw point 4 is fixedly mounted on handle 6, the diameter of section≤0.9mm of draw point.

In the present embodiment: described handle 1 and handle 6 are wooden handle.

In actual use, while getting bearing tree bark RNA, the handle 1 of operator's handheld sampler 2, sampling end 3 one sides are close to bark, observe groove 5 to being placed on the position that is conducive to observation, operator passes through handle 1 to sampler 2 application of forces, make in sampling end 3 oblique insertion barks, embed the amount of the sampling end 3 of hollow by observing groove 5 judgements simultaneously, extract sampler in good time, then bark is peeled off out from sampler 2 with draw point, pack in centrifuge tube, again centrifuge tube is thrown in the liquid nitrogen container carrying, finished whole sampling process.

Above-mentioned embodiment is intended to illustrate the utility model and can be professional and technical personnel in the field's realization or use; it will be apparent for those skilled in the art that above-mentioned embodiment is modified; therefore the utility model includes but not limited to above-mentioned embodiment; any description that meets these claims or instructions; meet and product and the technique of principle disclosed herein and novelty, inventive features, within all falling into protection domain of the present utility model.

Claims

1. a rubber tree bark microscale sampler assembly, comprise the sampler that contains handle, it is characterized in that: in sampler assembly, also comprise draw point, the external diameter 2mm of described sampler, long 5-6cm cylinder, front end is the sampling end of hollow, rear end is fixedly connected with handle, and a sidewall of sampling end is provided with axial observation groove, observes flute length 1cm, wide 1mm, observes groove forward position and sampling end face 1mm apart; Described draw point is fixedly mounted on handle, the diameter of section≤0.9mm of draw point.

2. rubber tree bark microscale sampler assembly according to claim 1, is characterized in that: described handle and handle are wooden handle.
