Description
Technical Field
The utility model belongs to the extraction element field especially relates to a children's product toxicology detects uses cell culture filter assembly.
Background
Filtration is a conventional and frequently used experimental operation technology for chemical, material and biochemical experiments, and the operation amount is large. In the prior art, a common glass funnel is generally used for filtering, but different filtering membranes, such as ceramic filtering membranes, cannot be used on the common glass funnel; if reduced pressure filtration is required, a buchner funnel plus filter flask is required for self-assembly. However, reduced pressure filtration is often not possible without a buchner funnel or filter flask, or even a rubber stopper connecting the buchner funnel and the filter flask. The problems are solved: if the filter bottle is not used, different filtering requirements of different experimental properties can be met simultaneously.
In the medical and biological fields, cell culture is often performed using cell culture plates to meet the needs of different experiments. During the cell culture process, various nutrients or treatment substances need to be added, and the substances need to be filtered before being added to meet the needs of cell culture. The existing filtration methods include vacuum filtration or filtration by a microporous syringe, for example, a multipurpose filter bottle and a using method disclosed in the patent with the patent number of CN102008842A are suitable for filtering stock solutions with different experimental requirements. The filtration can be carried out normally or by vacuum filtration; is suitable for routine filtration of general material chemistry and filtration of biochemical experiments. However, in the case of vacuum filtration or filtration with a microporous syringe, it is necessary to assemble a filter flask or syringe, perform filtration, and add the filtered material to the culture plate after filtration, which is troublesome and time-consuming. CN104830685A discloses a filtration auxiliary structure of cell culture container, including filtering the main part, filter the main part including the lateral wall that forms the accommodation space that holds the filter, accommodation space's bottom is provided with filtration membrane, the top surface of lateral wall is connected with the top circle through the spliced pole, the diameter of top circle is greater than accommodation space's internal diameter. The invention has simple structure and convenient use, can meet the requirement of filtering substances required by cell culture, saves time, can design accommodating spaces with different inner diameters according to different culture plates, and has wide application range.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide a filter equipment with hinge dress sweeps the subassembly, specifically be a cell culture filter assembly is used in children's product toxicology detection.
The utility model provides a technical scheme that technical problem adopted is:
the utility model provides a children's product toxicology detects uses cell culture filter assembly, includes the cartridge filter and sweeps the lid, sweeps the coaxial sealed lid dress of lid and at the cartridge filter up end, the cartridge filter be hollow cylindricly, at the coaxial solid filter screen of adorning in cartridge filter middle part, sweep the lid and be frustum shape cavity drum, the upper end is circular uncovered, and the lower part is circular uncovered, sweeps the lid in the coaxial solid windy net of adorning of lower part, the coaxial dress of cartridge filter upper end is sweeping the lid lower part.
Moreover, two vent holes are formed on the side wall of the purging cover.
Moreover, the filter cylinder is hollow and cylindrical, the diameter of the filter cylinder is gradually enlarged from bottom to top, and the filter cylinder is in flaring design.
And, a layer of non-woven fabric is adhered on the wind net.
The utility model has the advantages that:
the application provides a children's product toxicology detects uses cell culture filter assembly has a sealed upper cover, and the upper cover can adopt the aurilave to sweep, prevents that the cell culture liquid of concentration too high is filterable slowly, has effectively improved filtration efficiency.
The application provides a children's product toxicology detects and covers two air vents of system with cell culture filter assembly sweeping, can adjust with the finger, and the pressure that sweeps of aurilave is adjusted in shutoff one or two holes, guarantees that the filtration process is smooth and easy.
The application provides a children's product toxicology detects and has a distribution net with cell culture filter assembly sweeping the lower part of covering in, can carry out even distribution with the gas that aurilave blown down, prevents that specific air current is too big, leads to dangers such as liquid overflow.

Fig. 2 is a state diagram of fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
The utility model provides a children's product toxicology detects uses cell culture filter assembly, includes cartridge filter 5 and sweeps lid 2, sweeps the coaxial sealed lid dress of lid and at the cartridge filter up end, the cartridge filter is hollow cylindricly, by the diameter progressively enlarges on going up, is the flaring design, at the coaxial filter screen 4 of adorning admittedly in cartridge filter middle part for filter cell. The blowing cover is a frustum-shaped hollow cylinder, the upper end of the blowing cover is provided with a circular opening for embedding the filter cartridge, the lower part of the blowing cover is provided with a circular opening for embedding the lower part of the aurilave, and the lower part of the blowing cover is coaxially and fixedly provided with an air net 3 for uniformly distributing air blown off by the aurilave 1. The upper end of the filter cylinder is coaxially embedded at the lower part of the purging cover.
Two vent holes 6 are arranged on the side wall of the purging cover and used for blocking one or two of the vent holes by fingers to adjust the purging pressure.
The diameter of the filter cartridge is gradually enlarged from bottom to top, so that filter pipes with different sizes can be used, and the single purpose is prevented.
In order to improve the distribution effect of the wind net, a layer of non-woven fabric can be adhered on the wind net.
The application provides a children's product toxicology detects and uses cell culture filter assembly has a sealed upper cover, the upper cover can adopt the aurilave to sweep, prevent that the cell culture liquid of concentration too high is filterable slow, filtration efficiency has effectively been improved, it has two air vents to cover the system to sweep, can adjust with the finger, shutoff one or two holes, adjust the pressure that sweeps of aurilave, it is smooth and easy to guarantee the filtration process, there is a distribution net still in sweeping the lower part of covering, can carry out even distribution with the gas that the aurilave blown down, prevent that specific air current is too big, lead to dangers such as liquid overflow.
