Abstract
The utility model belongs to the technical field of little biological assay apparatus, concretely relates to piston tube formula agar plate hole puncher, including tubular thin wall hole sword, the lower extreme edge of a knife department of tubular thin wall hole sword sets up a steel wire and falls into two semicircles to the edge of a knife, sets up the gas pocket on the lateral wall of tubular thin wall hole sword, establishes the piston in the sword of tubular thin wall hole, the hinge joint pull rod, and the top of pull rod is equipped with the handle. The utility model discloses can take out agar piece when punching fast to the hole bottom face levels.
Description
Technical field
This utility model relates to a kind of agar plate card punch, is specifically related to a kind of test measuring Chinese medicine extract fungistatic effect for agar hole method, can carry out the device punched, belong to card punch technical field on the agar plate being coated with bacterium.
Background technology
In the bacteriostatic test of agar hole method (Odontothrips loti) external test liquid type medicine (Chinese medicine extract that water solublity is poor), laboratory typically uses the water absorption preferable sterilizing filter paper scraps of paper to absorb a certain amount of medicine and makes the pastille scraps of paper, or put the Oxford cup of heating on Agar Plating surface to add medicine, thus reach the purpose of fixing drug target.For the Chinese medicine extract that dissolubility is poor, the loaded down with trivial details operating procedure of its drug paper disk can strengthen the pollution probability of test, and the amount absorbed the drug often not reach test required, test wayward and standardization.Use Odontothrips loti or agar hole method can increase sample size, even if the most weak activity also can show the bacteriostatic activity of Chinese medicine extract.But, before the agar surface being coated with bacterium puts sterilizing Oxford cup, needing quickly heating Oxford cup, be placed on agar surface the most gently, the bad control of temperature of heating in operating process, the Oxford cup being in addition well placed is unstable, easily topples over.Because the Oxford cup put is to contact at agar surface gently, added with testing liquid medicine in the cup of Oxford so that culture dish can not upside down to put and (cover down, the end, is upward), use sterilizing FE Tiler need to be changed during cultivation, affect the normal growth of microorganism, cause result of the test inaccurate.And when applying the fungistatic effect that hole method measures liquid type Chinese medicine extract, need on agar plate, to get 4-5 aperture with card punch, existing punch method is to punch on agar plate with card punch (fixing more than one rustless steel hollow and thin-walled hole cutter on base), with sterilizing tweezers or other utensils, the agar in perforated pipe is taken out again, its shortcoming is to punch and take out agar to be undertaken in two steps, one card punch is only used for a kind of test and uses bacterium, standby multiple card punch of sterilizing is needed before experiment, sterilizing is needed after with, clean and sterilization, troublesome poeration, waste time and energy, urgently improve.
Utility model content
This utility model is intended to overcome the defect of prior art, a kind of piston tubular type agar plate card punch is provided, being undertaken in two steps with the punching and taking-up agar solving the existence of existing agar plate card punch, before and after troublesome poeration, and experiment, card punch needs the problem such as sterilizing, sterilization.
The purpose of this utility model is achieved through the following technical solutions:
A kind of piston tubular type agar plate card punch, including tubular type thin-wall hole cutter, the lower end knife-edge part of tubular type thin-wall hole cutter arranges a steel wire and the edge of a knife is divided into two semicircles, on the sidewall of tubular type thin-wall hole cutter, pore is set, piston is set in tubular type thin-wall hole cutter, piston cylinder lever connecting rod, the top of pull bar is provided with handle.
The outer surface of tubular type thin-wall hole cutter is provided with scale, to determine the punching degree of depth,
The beneficial effects of the utility model are: simple in construction, easy to use, can simplify operating procedure when punching, it is to avoid the cross infection between different agar plates, time saving and energy saving, can quickly remove agar block, and bottom surface, hole is smooth.Substantially increase work efficiency, economical and practical.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of piston tubular type agar plate card punch, including tubular type thin-wall hole cutter 1, the outer surface of tubular type thin-wall hole cutter 1 is provided with scale, to determine the punching degree of depth, the lower end knife-edge part of tubular type thin-wall hole cutter 1 arranges 5 edges of a knife of a steel wire and is divided into two semicircles, pore 6 is set on the sidewall of tubular type thin-wall hole cutter 1, in tubular type thin-wall hole cutter 1, sets piston 2, piston 2 cylinder lever connecting rod 3, the top of pull bar 3 is provided with handle 4, to facilitate push-and-pull.
During punching, tubular type of holding with a firm grip thin-wall hole cutter 1 inserts in agar plate, pore 6 can aerofluxus, reduce intraductal atmospheric pressure impact, convenient insertion, after reaching desired depth, rotating 180 °, steel wire 5 can be agar plate cutting and boring position agar block, make punching bottom surface smooth, then block pore 6 with finger, pull piston 2, i.e. may utilize suction and the agar block of cutting in drill process is sucked out.
Claims (2)
