Gravimetric analysis, micro-analysis, colloid detaches and the sample system of the analytical instrument such as sterility test and HPLC, MS, LC-MS, GC-MS
The filtering of the fluid samples such as standby, purifying, pre-treatment, biological products preparation, tissue culture medium (TCM), microbiological media, buffer solution, it is rotten
Purification, the clarification of the strong solution of corrosion, the filtering of a small amount of sample remove impurity in sample, precipitation etc..
Disposable needle-like filter is mainly using internal filter membrane come filter material, in laboratory research, it usually needs
Filter membrane taking-up is studied.Since the shell of disposable needle-like filter uses the sanitation-grade polypropylene material of excellent stability
Matter, using ultrasonic bonding, edge combine it is careful, it is high pressure resistant, thus obtain filter membrane it is very difficult.Existing laboratory is taking film
When generally filter is cut off using shear, to taking out filter membrane, but shear takes film not only time-consuming and laborious, but also very
It is be easy to cause filter membrane pollution, conventional efficient is reduced to influence experimental result.
Utility model content
Film device being taken for disposable needle-like filter the purpose of this utility model is to provide a kind of, it can be easily
Filter membrane in filter is taken out, and the pollution of filter membrane will not be caused.
To achieve the above object, the utility model adopts the following technical solution：
It is a kind of to take film device, including first handle and second handle for disposable needle-like filter, first handle and
Second handle is hinged by axis pin, torsional spring is arranged on axis pin, the both ends of torsional spring are fixed with first handle and second handle respectively
Connection, it is circle that the end set of the first handle, which has cutting piece, the cutting piece, and the center for cutting piece offers the first circle
Hole cuts on piece and is provided with blade；The end set of the second handle has a fixing device, the fixing device include pedestal and
The fixed station being fixedly installed on pedestal offers the second circular hole in the middle part of fixed station.
Preferably, the blade is fixedly installed in the outer circle for cutting piece, and the edge of a knife of blade is arranged vertically downward.
Preferably, a diameter of 22mm, a diameter of 8mm of the first circular hole for cutting piece.
Preferably, the blade is fixedly installed on the first circular hole for cutting piece, and the edge of a knife level of blade is down-set.
Preferably, a diameter of 22mm of first circular hole.
Preferably, a diameter of 6mm of second circular hole.
Preferably, the thickness of the blade is 0.05mm-0.2mm.
Preferably, the cutting piece, fixed station and blade are all made of stainless steel.
Blade is arranged by filter on first handle by the way that first handle and second handle is arranged in the utility model
Shell cut, to easily taking out filter membrane, fixing device is provided on second handle, filter can be fixed, side
Just shell is cut off.The utility model is simple in structure, of low cost, easy to operate, can not only easily take out filter membrane, and
The pollution rate of sample can be reduced, to provide good basis to subsequent experimental.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；

Specific implementation mode
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described reality
The section Example that example is only the utility model is applied, instead of all the embodiments.Based on the embodiments of the present invention,
Other all embodiments that those of ordinary skill in the art are obtained without making creative work belong to this
The protection domain of utility model.
Embodiment one
As shown in Figure 1 to Figure 3, a kind of film device that takes for disposable needle-like filter described in the utility model, packet
First handle 1 and second handle 2 are included, first handle 1 and second handle 2 are hinged by axis pin 5, and torsional spring is arranged on axis pin 5, turn round
The both ends of spring are fixedly connected with first handle 1 and second handle 2 respectively, and the end set of first handle 1, which has, cuts piece 4, cuts
Piece 4 is circle, and the center for cutting piece 4 offers the first circular hole 6, and the first circular hole 6 cuts the straight of piece 4 for making filter pass through
Diameter is 22mm, a diameter of 8mm of the first circular hole 6, cuts and is provided with a circle blade 7 in the outer circle of piece 4, the edge of a knife of blade 7 is vertical
