Embodiment 1
[0048] A filtration system that prevents cell rupture, see figure 1 , including filter 1, sample injection tube 2, liquid outlet tube 3, bubble detector 4, valve 5 and control part 6, details are as follows:
[0049] The sampling tube 2 is preferably made of a hose, such as polyvinyl chloride, and the sampling tube 2 communicates with the filter 1 to provide an inflow channel for the sample to enter the filter.
[0050] The liquid outlet pipe 3 communicates with the filter 1 and is used to provide an outflow channel for the filtered filtrate.
[0051] The bubble monitor 4 is arranged on the sampling tube 2, and is used to monitor whether there are bubbles in the sampling tube 2. The bubble monitor 4 is preferably an ultrasonic bubble monitor, such as Beijing Dongfang Jinrong Ultrasonic Electric Co., Ltd. Production of bubble monitors.
[0052] The valve 5 (a solenoid valve is used here) is arranged on the liquid outlet pipe 3, and is used to control whether the filtered filt...
Embodiment 2
[0059] The difference between this embodiment and embodiment 1 is that the filter structure is different, see image 3 ,specifically is:
[0060] 1. At least one of the bottom and the top of the filter 1 is provided with a good light-transmitting observation window; preferably, the bottom and the top of the filter 1 are provided with a good light-transmitting observation window 1.5, and the two Said observation window is arranged correspondingly, light can enter from one observation window, after reaching and passing through said filter membrane, exit from another observation window; The minimum distance from said filter membrane to the objective lens of the microscope through the observation window is greater than that of the microscope objective lens One focal length and infinitely close to one focal length; the observation window is an observation window with a flat surface, and the material with good light transmittance refers to a material with a light transmittance of mo...
