Abstract
The utility model discloses a plastic centrifuge tube capable of performing sterile filtration, which belongs to chemical and biological experiment equipment, in particular to a centrifuge tube for centrifugal separation. The plastic centrifuge tube capable of performing sterile filtration is characterized in that: a top cover which can be sealed is arranged at the top end of a cylindrical filtering tank body; a vertical glass filter element is arranged at the bottom in the tank body, wherein a layer of 0.22-micron filter membrane is cured on the surface of the vertical glass filter element; and a lower tank body is connected with the filtering tank body, and a connection spiral coil is sleeved on the periphery of the joint. The whole centrifuge tube structure disclosed by the utility model can be disinfected and sterilized. When in use, the filtrate to be filtered is placed in the filtering tank body which is covered with the top cover; then the filtering tank body is put into a centrifuge of which the centrifugal force is set as required; and the liquid passes through the filter membrane, the filter element arrives to the lower tank body, and bacteria can not pass through the filter membrane and the filter element but stay in the filtering tank body, thereby achieving the aim of filtering bacteria from the liquid. The whole process can be completely performed in a sterile condition, thereby being favorable for reducing the possibility that the liquid in the lower tank body is polluted by bacteria again.
Description
Technical field
The utility model belongs to the chemical-biological experimental facilities, especially for the centrifuge tube of centrifugation usefulness.
Background technology
In biological, chemical experiment, usually need filter and obtain bacteria-free filtrate the bacterium in the experimental liquid, filter plant one commonly used be the rate of filtration slow, the 2nd, filtrate easily by living contaminants.
The utility model content
In order to overcome the deficiency of existing filter plant, the utility model provides a kind of plastic centrifuge tube that can carry out aseptic filtration, and this plastic centrifuge tube that can carry out aseptic filtration can carry out aseptic filtration easily.
The utility model solves the technical scheme that its technical problem adopted: a kind of plastic centrifuge tube that can carry out aseptic filtration; It is characterized in that: sealable top cover is equipped with on columnar filtration tank body top; The tank body inner bottom part is equipped with the vertical glass filter core that melts that surface cure has 0.22 micron filter membrane of one deck; Lower tank links to each other with the filtration tank body, and the connection periphery is with the connection bung flange.
The beneficial effect of the utility model is: the sterilization that can carry out disinfection of a whole set of centrifuge tube structure.Assembling complete equipment during use; The filtrating that need filter is put into filtration tank body inner cap upper top cover; Put into centrifuge and set centrifuge centrifugal force as required, liquid is through filter membrane, and filter core arrives lower tank; Thereby bacterium can not reside in through filter membrane and filter core and filter in the tank body, reaches the purpose that bacterium in the liquid is filtered out.The process of this operation can be carried out under aseptic condition fully, is more conducive to reduce in the lower tank liquid once more by the possibility of germ contamination.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Among the figure, 1. top cover 2. filters tank body, and 3.0.22 micron filter membrane 4. hangs down and melts the glass filter core, 5. connects bung flange, 6. lower tank.
The specific embodiment
The specific embodiment of the utility model is, and is as shown in the figure:
Embodiment 1; A kind of plastic centrifuge tube that can carry out aseptic filtration; It is characterized in that: sealable top cover 1 is equipped with on plastic columnar filtration tank body 2 tops; The tank body inner bottom part is equipped with the vertical glass filter core 4 that melts that surface cure has 0.22 micron filter membrane 3 of one deck, and lower tank 6 links to each other with the filtration tank body, and the connection periphery is with and connects bung flange 5.The filtrating that to filter during use is put into and is filtered tank body inner cap upper top cover; Put into centrifuge and set centrifuge centrifugal force as required; Liquid passes through filter membrane; Filter core arrives lower tank, filters in the tank body thereby bacterium can not reside in through filter membrane and filter core, reaches the purpose that bacterium in the liquid is filtered out.The process of this operation can be carried out under aseptic condition fully, is more conducive to reduce in the lower tank liquid once more by the possibility of germ contamination.
