Specific embodiment
Referring to Fig. 1, a kind of microorganism separator for drug Micro biological Tests comprising have: being used to prepare medicine
The homogenizer 2 of product dilution；The lower section of the homogenizer 2 is arranged in liquid collecting container 1；The liquid collecting container 1 includes connection
Several ejecting heads 110 in its lower end；Bowl 3 is filtered, the lower section of the liquid collecting container 1 is set；During the filter bowl 3 includes
Cavity 310；The inner wall of the filter bowl 3 is connected to the hollow cavity 310；Filter membrane 4 is attached on the inner wall of the filter bowl 3；It takes out
Empty machine 6 is tightly connected with the hollow cavity 310；Drain pipe 7 is connect with the vacuator 6.Wherein it is preferred to described
Liquid collecting container 1 is connected on the filter bowl 3 by bracket 340.
It is important to note that after experiment by multiple Expenses Cost, inventors have found that the filter bowl 3 is interior
Wall circular arc degree is preferably 120 degree, and the filter bowl 3 of such structure can be more quickly completed the filtering and micro- life of chemicals dilating liquid
The separation of object.
Drug is prepared into dilution by the homogenizer 2, and dilution flows into the liquid collecting container 1, and dilution continues
Cream is sprayed by the ejecting head 110 to enter in the filter membrane 4 being arranged on the inner wall of the filter bowl 3.At this point, due to the vacuator 6
