Abstract
The invention discloses a method and a device for filtering and subpackaging a microorganism culture medium. A filtering sieve is arranged at the upper part of a filtering cup body; a filtering gauze is put on the filtering sieve; an overflow nozzle positioned below the filtering sieve is arranged on the filtering cup body; the microorganism culture medium is poured from the top of the filtering cup body; after the microorganism culture medium is filtered by the filtering gauze, a filtrate deposits at the bottom of the filtering cup body; and the deposited filtrate is poured into a subpackaging container through the overflow nozzle, so that the microorganism culture medium are filtered and subpackaged at one time. According to the invention, filtering and subpackaging are integrated in the same filtering cup body, during filtering, the operation is simple, quick, time-saving and labor-saving; during subpackaging, a microorganism culture solution only needs to directly flow out from the overflow nozzle, so that the microorganism culture solution is not required to be poured into a funnel, the operation steps are reduced, and the microorganism culture solution is difficult to cool and concentrate. Therefore, a phenomenon of concentration of the filtrate caused of low speed during filling in the conventional subpackaging mode is avoided.
Description
Technical field
The present invention relates to a kind of filter method and device, particularly a kind of method and device that filters the packing microbiological culture media.
Background technology
In the process of substratum such as making in laboratory PDA, oat, rye, often the residue in the nutrient solution need be filtered, traditional method is to filter with the substratum that filter paper or gauze will prepare while hot.When using filter paper filtering, folded filter paper is become corrugated shape, be layered on the funnel and filter, this method is simple to operate, but filtration velocity is very slow, and nutrient solution solidifies easily.When using filtered through gauze, it is folded into 4~6 layers directly is enclosed within the beaker mouth, this method speed is very fast, but gauze is easily fallen into beaker when filtering, and filtration yield more for a long time, and a people is not easy to operate, often needs two people just can finish together.When the nutrient solution after filtering was carried out packing, method commonly used was that nutrient solution is transferred in the funnel that is connected with spring pinchcock, and the degree of tightness of pressing from both sides by control spring is transferred to Erlenmeyer flask or test tube with it.Because the funnel finite capacity is slow as if operating, the very fast cooled and solidified of nutrient solution.Yet, also do not collect the easy device that substratum filtered and be packed as one in the laboratory at present.
Summary of the invention
Technical problem to be solved by this invention is: a kind of method and device that filters the packing microbiological culture media is provided, and disposable filtration and the packing of finishing microbiological culture media of its energy, and have simple in structure, easy to use, time saving and energy saving advantage.
The method of filtering the packing microbiological culture media that is achieved in that of the present invention arranges filter sieve on the top of filtering cup, and places at filter sieve and to filter gauze, is in the mouth that overflows below the filter sieve filtering cup setting; Microbiological culture media is poured into from the top of filtering cup, microbiological culture media is through after filtering filtered through gauze, filtrate is deposited on the bottom of filtering cup, and the filtrate of deposition is poured in the branch packaging container by overflowing mouth again, thus the disposable filtration packing of finishing microbiological culture media.
Filter the device of the method for packing microbiological culture media, comprise the filtration cup, the inside upper part of filtering cup is provided with inwardly protruded planar rings, in filtering cup, be provided with filter sieve, the top of filter sieve is corresponding with planar rings, be provided with bowl cover at the top of filtering cup, be provided with one at the sidewall that filters cup and overflow mouth, overflow mouth and be in the filter sieve below with the link position that filters cup.
Be provided with handle in the position of overflowing the mouth correspondence.The convenient use.
This has scale marks in the lower sidewall of filtering cup.The amount of nutrient solution is convenient to measure, observes and is added water and supplies volume required in the indication cup.
Be provided with lid overflowing mouth.When filtering, can close, when packing, open.
Be provided with internal thread in the outside of filtering the cup top, be provided with corresponding with it outside screw in the inboard of bowl cover.The mode that is threaded can guarantee to filter reliable, the good sealing effect of being connected of cup and bowl cover, and conveniently takes off.
Owing to adopted technique scheme, compared with prior art, the present invention adopts and will filter and packing is integrated into mode in the same filtration cup, and is simple to operate during filtration, quick, time saving and energy saving; During packing, only microbial culture medium directly need be got final product from overflowing the mouth outflow, not need to change over to again funnel, reduce operation steps, and be difficult for cooled and solidified.The situation of having avoided existing packing mode when can, to cause filtrate to be solidified slowly owing to speed.Method of the present invention is simple, and the device that adopts is made easily, and is with low cost, and result of use is good.
