Abstract
This novel microbial solid medium card punch, punching ring therein is the hollow cylinder of tubular, punching ring is angled 100 ° 150 ° with punching ring rod, when card punch is tiltedly put in insertion culture dish, it is vertical with the solid culture primary surface in culture dish to punch ring wall, regular cylindrical body shape solid culture based specimen can be got when pushing card punch, there is 10 40 micro-holes, a diameter of 0.11cm 0.30cm of micro-hole on punching ring.The utility model novel microbial solid medium card punch can get regular cylindrical body shape solid culture based specimen, avoid culture dish opening excessive, the youngster for reducing living contaminants leads, time required for reducing during heat sterilization, after solving solid medium punching, culture medium is sticked be not easy to fall on inwall the problem of, substantially increases conventional efficient.
Description
【Technical field】
It the utility model is related to a kind of card punch, particularly microbiological culture media card punch
【Background technology】
Card punch, it is widely used in medical science, agronomy, industry etc. microculture and face-off experiment, in microorganism
In related science research, it is related to solid medium card punch, is widely used in the cutting of solid medium.At present, commonly use solid
Body culture medium cutting method is then using the "T"-shaped card punch cutting punched to solids.The patent No.
Large area sterilizing dead angle occurs in CN201320592980.X, Experiment on Microbiology card punch, it is impossible to complete sterilizing, and also it is this
Setting type card punch, need to open culture dish lid completely in punching, bacterial spore can disorderly fly everywhere, asking for living contaminants occur
Topic, increase pollution probability.Patent No. CN201420388064.9 is improved, and in drill process, is cultivated without opening completely
It ware lid, only need to open a seam, in the laterally inserted culture dish of card punch, carry out punching sampling.When the horizontally-parallel insertion of card punch
When in culture dish, because culture dish wall is highly more than punching ring height, card punch can not touch the solid culture in culture dish
Base, it can not sample, in order to carry out punching sampling, it is therefore desirable to tiltedly put card punch, oblique hole can only be got by tiltedly putting card punch, punching
The culture medium solid block of sampling out is irregular, is unfavorable for testing, and when carrying out heat sterilization to card punch, firing rate
Slowly, efficiency is low.
【The content of the invention】
To solve problem above, the utility model provides a kind of novel microbial solid medium card punch, can solved miscellaneous
Bacterium pollution problem, make experimental result with more science.
The utility model novel microbial solid medium card punch, there is punching ring, punching ring bar, connecting rod and thermal insulation
Handle, it is characterised in that：Punching ring is the hollow cylinder of tubular, and phase is welded at punching ring bar and the one of punching ring wall upper end
Even, the punching ring wall on weld vertical direction forms fixed angle with punching ring bar, and its angle is 100 ° -150 °, when beating
When hole device is tiltedly put in insertion culture dish, punching ring wall is vertical with the solid culture primary surface in culture dish, can when pushing card punch
To get regular cylindrical body shape solid culture based specimen, avoid culture dish opening excessive, reduce the probability of living contaminants；Punching ring
Bar and connecting rod are designed as the formula of being weldingly connected, and both are tightly secured together；There are 10-40 micro-hole, micro-hole on punching ring
A diameter of 0.11cm-0.30cm, micro-hole is set to increase contact of the solid medium with air after punching in punching ring
Face, it is easy to the solid medium in punching ring to depart from perforating head, on the other hand, is also convenient for before experiment starts or is fought each other after terminating
Orifice ring carries out heat sterilization, is that sterilizing efficiency is higher.
The utility model novel microbial solid medium card punch, it is characterised in that punching ring is hollow cylinder
Structure, the internal diameter of punching ring is 0.2cm-1.5cm, is highly 0.3cm-1.0cm, and the length of connecting rod is 3.5cm-6.0cm, hand
Handle outer wrapping layer of insulation material.
The utility model novel microbial solid medium card punch can get regular cylindrical body shape solid culture basic pattern
Product, avoid culture dish opening excessive, reduce the probability of living contaminants, the time required for reducing during heat sterilization, solution
After solid medium of having determined punching, culture medium is sticked be not easy to fall on inwall the problem of, substantially increases conventional efficient.
【Brief description of the drawings】
Fig. 1 is structural representation of the present utility model；Fig. 2 is the utility model punching ring structural representation
1st, punching ring；2nd, micro-hole；3rd, sword is punched；4th, punching ring bar；5th, connecting rod；6th, heat insulation bat-handle
【Embodiment】
A kind of novel microbial solid medium card punch, including punching ring bar (4), punching ring (1), punching sword (3), company
Extension bar (5), insulated handle (6).Punching ring bar (4) length 5cm, one end are closely weldingly connected with punching ring (1), punching ring bar
(4) it is connected with punching ring (1) and forms 120 ° of angle；The other end of punching ring bar (4) closely welds phase with connecting rod (5)
Even, the other end and heat insulation bat-handle (6) of connecting rod (5) are closely coupled.Punching ring (1) is tube-shaped column body, hollow, and outer rim is set
It is 0.65cm to be equipped with flat punching sword (3) internal diameter, is highly 0.45cm.Connecting rod (5) closely connects in left end and punching ring bar (4)
It is connected to together, right-hand member is fixed together with heat insulation bat-handle (6).
Claims (2)
