Biofilter refers to a kind of obstruction bacterium by filtering out bacterium, and collection obtains the filter of bacteria-free filtrate.Carefully
Bacterium filter is divided into deep bed filter and cellulose membrane filter.Wherein cellulose membrane filter refers to that utilization is with cellulose acetate
The artificial membrane of the cavities with uniform aperture of main material is filter membrane, cannot pass through filter more than microorganism more than aperture limit
Film, to realize the purpose of filtration sterilization.In the filter operation for doing biological cell culture medium, cellulose filter membrane is placed on filtering
It is filtered sterilization in device, finally collects and obtains bacteria-free filtrate.Common filter device includes that funnel and filtrate are collected
Container, funnel are fixed on above filtrate collection vessel, and filtrate collection vessel is equipped with the tubule of ventilation, for connecting nutsch filter.
It before filter operation, needs for cellulose filter membrane to be placed in the funnel of filter device, entire filter device is superscribed into newspaper
Or cloth bag, it is placed in high-pressure steam sterilizing pan, high pressure steam sterilization is carried out to it.But in actual operation, after sterilizing sometimes
There is the problem of filter membrane rupture, at this moment needs to repeat aforesaid operations, until filter membrane is complete after sterilizing.
Utility model content
The purpose of this utility model is to overcome in biological cell culture medium filtration experiment, to filter device and filter membrane
Carry out the problem of filter membrane ruptures when high pressure steam sterilization.The utility model provides a kind of structure and is simple and convenient to operate, can overcome
A kind of bacteriological filter apparatus convenient for high pressure steam sterilization of the technical problem.
Purpose of the utility model is realized as follows: a kind of bacteriological filter apparatus convenient for high pressure steam sterilization, including
Top cover, funnel and liquid trap, the top cover are removably to be fixedly connected with the funnel, and the funnel is with the liquid trap
It is removably fixedly connected, has on the liquid trap outer wall along symmetrical 2 the first round tubes of funnel axis direction, first circle
It manages and is communicated inside the liquid trap, the top cover includes top surface, changeover portion and the interconnecting piece of cone, the changeover portion connection
The top surface and interconnecting piece, the changeover portion have certain gradient, have on the changeover portion 2 downwards to stretch out with outside
Second round tube, 2 second round tubes it is symmetrical along top cover axis direction and with communicated inside top cover, first round tube with it is described
The cross-sectional area of second round tube is equal.
Further, the funnel is to be threadedly coupled with the top cover to the utility model.
Further, the top cover top is fixed with the first connection buckle to the utility model, fixed on the funnel outer wall
There is the second connection buckle, connecting rope is housed on first connection buckle and second connection buckle.
Further, the funnel is to be threadedly coupled with the liquid trap to the utility model.
Further, the liquid trap is cylindric to the utility model.
The utility model increases top cover compared with existing filter device, is threadedly coupled between top cover and funnel, pushes up
The second circular hole identical as the cross-sectional area of the first circular hole is covered, in this way when carrying out high pressure steam sterilization to the utility model,
Avoid filter membrane up and down pressure change it is too big and the problem of cause filter membrane to rupture.The top surface of top cover is cone, the second circular hole bottom
Down, be conducive to the condensed water generated when high pressure steam sterilization outflow.Top cover is connected with funnel by connecting rope, in use
Top cover will not be lost because of random place, more convenient to use.By liquid trap be designed as cylindrical shape be in order in using more
Convenient for cleaning.Therefore, the utility model is simple, easy to use with structure, prevents filter membrane during high pressure steam sterilization from rupturing
Beneficial effect.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
