Description
Technical field
The utility model is related to biological technical fields, and in particular to a kind of simple bacteria filter.
Background technology
In traditional medical test and Food Inspection, when carrying out bacteria count to fluid sample, generally use culture
After base cultivates sample, bacterium colony is counted.
A kind of membrane filter exists in the prior art, for sterilizing in biological species scientific research, this membrane filter
In be equipped with using cellulose acetate as the filter membrane of main material, on filter membrane have homogeneous aperture cavities, liquid to be filtered is fallen
Enter in membrane filter, more than microorganism more than aperture limit cannot by cavities, therefore liquid filtered on filter membrane after it is thin
Bacterium is just all stayed on filter membrane.
But existing membrane filter is structure as a whole mostly, and filter membrane is not easily taken out, and the inconvenient bacterium on filter membrane carries out
It counts.
Utility model content
The purpose of this utility model is to provide a kind of simple bacteria filters, can facilitate taking-up filter membrane, to thin on filter membrane
Bacterium is counted.
In order to achieve the above objectives, the utility model adopts the following technical solution：
A kind of simple bacteria filter, including filtrate housing, equipped with filter membrane and the branch for being used to support filter membrane in the filtrate housing
Support filter plate, the filtrate housing includes upper shell and lower housing, and upper shell and lower housing be detachably connected, upper shell be equipped with into
Liquid mouth, lower housing are equipped with liquid outlet, and lower housing is connected with support filter plate.
The operation principle of this programme is：
Liquid to be filtered enters from inlet in filtrate housing, and the filter membrane set in filtrate housing is to the bacterium in liquid
It is filtered, support filter plate is used to support filter membrane, and after filtering, bacterium is stayed on filter membrane, and the liquid after sterilizing is arranged by liquid outlet
Go out, upper shell is removed from lower casing, take out filter membrane, you can to carrying out counting measure after the Bacteria Culture on filter membrane.
Following technique effect can be reached using this programme：
1st, sterilizing on the one hand can be filtered, on the other hand can facilitate extraction filter membrane, the bacterium on filter membrane is counted
It measures；
2nd, it is simple in structure, it is easy to operate, only liquid need to be poured into inlet, remove upper shell, taking out filter membrane can carry out
Bacteria Culture counts.
Further, lower housing is equipped with filter membrane cannibalized equipment.Filter membrane is placed directly on support filter plate, after liquid filtering,
Bacterium is stayed on filter membrane, if directly taking filter membrane with hand, hand can be stained with bacterium, is gripped with the fixture of clip class, and due to filter membrane
Stickiness with supporting filter plate is higher, and the filter membrane for being not easy to be attached on support filter plate picks up, it could even be possible to by filter membrane clip
It is bad, on lower housing filter membrane cannibalized equipment is set to pick and place filter membrane, be on the one hand avoided that hand contacts directly filter membrane, it on the other hand can be light
Pine extraction filter membrane.
Further, lower housing is equipped with filter membrane clamping device.Filter membrane clamping device can clamp filter membrane edge, not influence
While filter membrane is filtered liquid, taking-up filter membrane can be facilitated.
Further, the filter membrane clamping device includes plier and is arranged at the clamp holders of lower housing both sides, clamp holder for two simultaneously
It is hinged by axis pin, plier includes two clamping plates, and two clamping plates are separately fixed at two clamp holder tops.First by filter membrane side before filtering
Along the gap among two clamping plates is placed in, two clamp holders are rotated, two clamping plates is made to clamp filter membrane edge, when liquid filters,
Bacterium is stayed on filter membrane, will not be stained with clamp holder, after the completion of filtering, lifts clamp holder, and filter membrane is also raised, and hand is avoided to contact directly filter
Film is stained with bacterium；In addition, clamping plate type avoid filter membrane clip is bad.
Further, upper shell and lower housing are threadedly coupled.Upper shell and lower housing are tightened, upper shell and lower housing
It is structure as a whole, upper shell is screwed down from lower housing, upper shell departs from lower housing, simple and convenient.
Further, it is provided with to place the locating groove of clamp holder on lower housing lateral wall.Clamp holder is placed in locating groove,
Clamp holder can be avoided to block the screw thread between upper shell and lower housing, prevent upper shell with lower housing from being closely joined together.
Further, thread fitting between clamp holder and upper shell.When clamp holder is sticked into locating groove, screw thread on clamp holder with
Screw thread between upper shell is fitted close, and is not on the one hand influenced the threaded connection between upper shell and lower housing, is on the other hand pressed from both sides
Thread fitting between handle and upper shell, which is avoided that between clamp holder and upper shell, generates gap, leaks out liquid.
Further, gasket is equipped between locating groove and clamp holder.After clamp holder sticks into locating groove, gasket is avoided that
Gap is generated between locating groove and clamp holder, is let the liquid out.
Further, rubber spacer is equipped on the inside of clamping plate.Rubber spacer, which is avoided that when clamping plate clamps filter membrane, damages filter membrane.
Further, clamp holder end is hinged with the finger circle convenient for finger insertion.When needing clamp holder sticking into locating groove, turn
The dynamic circle that refers to makes finger circle be adjacent to clamp holder, and when needing to lift clamp holder, rotation refers to circle and finger is facilitated to be inserted into.
