Description
Technical field
The utility model is related to filter technical field, more particularly to a kind of filter membrane pressurizing filter device.
Background technology
In the lab, filtering is most basic operating process, for filtering precipitation, separating insoluble matter etc..
The conventional filter method in current laboratory mainly includes filter paper filtration method, centrifugation filtration method and pressure filtration
Method.Filter paper filtration method low cost, but loss of liquid amount is big, poor filtration effect；Its filter efficiency of centrifugation filtration method is high, but
Centrifuge is expensive, high cost, not good to fine particle separating effect；Syringe and the compression filtration of filter membrane combination,
The method is simple to operate, and separating effect preferably, but is pressed by finger prosthesis, therefore the pressure that syringe piston handle is produced
Power is smaller, in the more solution of impurity screening, will certainly cause filter membrane replacing frequently, when sample is more, also results in hand
Refer to DOMS, so as to increase cost of labor and filter membrane cost.
Utility model content
For problem above, the utility model patent purpose is to devise a kind of filter membrane pressurizing filter device, is being ensured
On the premise of filter effect, the lever principle using stamping machine reduces the pressure of artificial force side, increases syringe piston pommel
Pressure, so as to reduce cost of labor, reduce and change filter membrane frequency, overcome the weak point during traditional membrane filtration,
Greatly improve filtering rate and conventional efficient.
The specific technical scheme of the utility model is as follows：
A kind of filter membrane pressurizing filter device, including base (1) and the stamping machine (2) on the base (1) and
Fixed support (3), is provided with fixing device (4) on the fixed support (3), injection dress is provided with the fixing device (4)
Put (5), the upper end of the injection device (5) is connected with the stamping machine (2), the exit of the injection device (5) is provided with
Filter membrane is provided with filter (6), the filter (6), the lower end of the filter (6) is provided with sample divider (7), described solid
Protective cover (8) is also equipped with fixed rack (3), the filter (6) is internal installed in the protective cover (8).
Further, sample divider (7) described in the utility model is on collector firm banking (9).
Further, protective cover (8) described in the utility model is transparent protective shield.
Further, fixing device (4) described in the utility model can be adjusted up and down on fixed support (3).
Further, filter membrane described in the utility model uses water system polyethersulfone membranes.
Compared with prior art, the device is provided more the filter membrane pressurizing filter device that the utility model is provided using stamping machine
Big pressure, on the premise of filter effect is ensured, the characteristics of with fast power-saving simple to operate, its rate of filtration is tradition side
2 times of method, while the rate of filtration is improved, reduce the frequency of filter membrane replacing, and its frequency for changing filter membrane is conventional method
1/2, reduce filter membrane cost；Additionally, complete equipment is cheap, it is easy to promote the use of.
