Description

Double-headed hole puncher for fungal pathogen experiment

technical field

The utility model relates to a hole puncher, in particular to a double-head hole puncher for fungal pathogen experiments.

Background technique

In the cultivation and purification of fungal pathogenic bacteria and related research experiments, it is necessary to take a large number of bacteria cakes from the petri dish and transfer them to another medium plate for cultivation. Most of the punchers currently used are ordinary punchers, and the fungus cake is not easy to separate from the puncher, and tools such as tweezers are needed, which is inefficient and time-consuming. Chinese Patent Publication No. CN203490097U, date of publication is March 19, 2014, utility model name: puncher for microbiological experiments, consisting of a perforating tube and a capsule-shaped rubber head, mainly by the negative pressure formed by extruding the capsule-shaped rubber head The method of picking agar blocks and transferring them under positive pressure has the characteristics of simple structure, low cost, and convenient use. However, the patent has the disadvantages of low operating efficiency, time-consuming and labor-intensive work because it is a single hole.

Utility model content

The purpose of this utility model is exactly to provide a kind of simple in structure, high in operating efficiency, time-saving and labor-saving double-hole puncher for fungal pathogenic bacteria experiment aiming at the existing problems of the above-mentioned prior art.

The purpose of this utility model is achieved through the following technical solutions: a double-head puncher for fungal pathogen experiments, including a casing and a piston push rod arranged in the casing, wherein: two holes are arranged on the bottom surface of the casing. A cylindrical perforated tube.

The spacing between the two perforated tubes is 1-3 mm. The inner diameter of the perforated tube is 1-6 mm, the height is 3-10 mm, and the wall thickness is 0.2-1 mm.

The beneficial effect of the utility model is that two bacteria cakes can be taken and transferred at the same time through one operation, and has the advantages of high operation efficiency, time saving and labor saving, and simple structure.

Description of drawings

Fig. 1 is the structural representation of the utility model.

In the figure: 1. Sleeve 2. Piston push rod 3. Perforated tube.

Detailed ways

Describe the specific embodiment of the utility model in detail in conjunction with accompanying drawing 1.

As shown in Figure 1: a double-head puncher for fungal pathogen experiments, including a casing 1 and a piston push rod 2 arranged in the casing, wherein: two cylindrical holes are arranged on the bottom surface of the casing Tube 3, the distance between two perforated tubes is 1-3 mm, the inner diameter of the perforated tube is 1-6 mm, the height is 3-10 mm, and the wall thickness is 0.2-1 mm.

When using the utility model, first push the piston push rod 2 to the bottom of the piston casing 1, vertically press the perforated tube 3 to the bottom of the culture dish, and directly cut off two bacteria cakes, at this time the perforated tube 3 It is a relatively closed space with the colony block. Pull up the piston push rod 2 to suck the bacteria cake from the petri dish. When moving it to a suitable position on another culture medium plate, press down the piston push rod 2. Under the impact of the airflow, the absorbed bacteria cake will fall smoothly from the perforated tube 3, and two bacteria cakes can be picked up and transferred at the same time through one operation.
