Abstract
The utility model discloses a microbial cultivation base filtering funnel, this filtering funnel include beaker flask (3) of an uncovered funnel shape, and a cylindrical embedding portion (4) is connected to the bottom of beaker flask (3), and bottom and triangular flask (5) as medium container of this cylindrical embedding portion (4) are connected, be equipped with filter screen (2) in the bottom of beaker flask (3), this filter screen (2) cover cylindrical embedding portion (4) upper portion opening, it filteres out mouth (1) to be equipped with one at the edge suitable for reading of beaker flask (3). The utility model discloses in experiment in the use, through the liquid medium that heat sterilization's filtering funnel has kept the sterilization pours the culture dish into under aseptic condition in, guaranteed that the purity of culture medium is peaceful flat whole in the culture dish, the utility model discloses with adopting gauze filter's method improvement to filter for microbial cultivation base filtering funnel among the prior art, have advantages such as easy operation, simple structure, low cost, later stage convenient to use.
Description
Technical field
This utility model relates to microbiological culture media defecator, belongs to scientific experiment equipment technical field.
Background technology
It is very extensive that microbiological culture media filters range of application in experimentation, but in experimentation, microorganism culturing gene was placed and be there will be partial medium condensation situations for a long time or culture medium itself has precipitate, result in that culture medium in culture dish is impure or flat board is uneven affects the problem such as growth of microorganism or test data mensuration.And in conventional experimentation, defecator is usually the porose materials such as gauze, in use often with extraneous contact, it is impossible to ensure in experimentation not by other living contaminantses, cause that experimental result is inaccurate.Therefore, developing a kind of novel microbiological culture media defecator is necessary to solve the problems referred to above.
Summary of the invention
The purpose of this utility model is the defect for existing culture medium defecator, a kind of microbiological culture media is provided to cross pan, when this device can be avoided using, culture medium is by living contaminants, and this device has reusable, processing ease, simple in construction, the advantage such as with low cost.
The technical solution of the utility model is such that
First, this utility model is that such a microbiological culture media crosses pan, this is crossed pan and includes a uncovered funnel shaped beaker flask, and the bottom of beaker flask connects a cylindrical Embedded Division, and the bottom of this cylinder Embedded Division is connected with the triangular flask as medium container；Being provided with drainage screen in the bottom of beaker flask, cylinder Embedded Division upper opening is hidden by this drainage screen；It is provided with one at the edge suitable for reading of beaker flask and leaches mouth.
Further, beaker flask, leaching mouth and cylindrical Embedded Division is the structure adopting glass to be made, such one is easy for observing the situation of culture medium filter process, and two are easy for carrying out high temperature sterilize.
Preferably, cylindrical Embedded Division diameter is equal with triangular flask internal diameter of the bottleneck or cylindrical Embedded Division diameter is smaller, so that the two is easy to adopt embedded mode connection, certainly, cylindrical Embedded Division can also threadedly be connected with the bottleneck of triangular flask, and such assembly and disassembly are all relatively convenient.
This utility model is in experiment use procedure, and the pan of crossing through high temperature sterilize maintains the fluid medium of sterilizing and pours under sterile conditions in culture dish, it is ensured that in culture dish, the purity of culture medium and flat board are smooth；This utility model is crossed pan be filtered being adopted the method for gauze strainer filtering to be improved to microbiological culture media in prior art, the advantage such as have simple to operate, simple in construction, with low cost, the later stage is easy to use.
Accompanying drawing explanation
Fig. 1 is that microbiological culture media of the present utility model crosses pan and triangular flask assembling use view；
Fig. 2 is that microbiological culture media of the present utility model filters bucket structure schematic diagram；
Description of reference numerals: 1-leaches mouth, 2-drainage screen, 3-beaker flask, 4-cylinder Embedded Division, 5-triangular flask.
Detailed description of the invention,
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Referring initially to Fig. 1, as can be seen from Figure 1, microbiological culture media of the present utility model is crossed pan and is arranged on triangular flask 5, triangular flask 5 is the container of microbiological culture media, pan of crossing of the present utility model is embedded into the bottle mouth position of triangular flask 5 by cylindrical Embedded Division 4, the top of cylindrical Embedded Division 4 is connected with uncovered funnel shaped beaker flask 3 bottom, and the two joint portion is provided with drainage screen 2 and separates, and leaches mouth 1 and is located at beaker flask upper limb.
Embodiment 1:
As it is shown in figure 1, microbiological culture media crosses pan is of a size of 0.5cm～1cm by leaching mouth 1(), drainage screen 2(diameter 2.5cm～3cm), beaker flask 3(back cut diameter 5cm～8cm), cylindrical Embedded Division 4(diameter 2cm～3cm) and triangular flask 2 constitute.The first half of device is uncovered funnel shaped beaker flask 3, leaches mouth 1 and is located at beaker flask 3 upper limb, and drainage screen 2 is positioned at above the bottleneck of triangular flask 5, and bottom is the cylindrical Embedded Division 4 that diameter just suits with triangular flask 5 bottleneck.During use, pan after high temperature sterilize, is inserted it into equipped with toppling over filtration culture medium in the triangular flask 5 of culture medium together with culture medium in superclean bench.There is simple to operate, simple in construction, the advantage such as with low cost, the later stage is easy to use.
Certainly, being more than concrete exemplary applications of the present utility model, this utility model also has other embodiment, all employings to be equal to replacement or the technical scheme of equivalent transformation formation, all falls within the protection domain required by this utility model.
