ABSTRACT:
An elongate, portable, hand-operated assembly adapted to create either a negative or positive pressure within the interior thereof, with the device being capable of having a hypodermic needle removably mounted on either end thereof. The assembly may be actuated to create a negative pressure to draw a liquid that may contain entrained particles of solid material into the interior of the assembly. After the assembly has introduced liquid therein in a desired volume, it may subject the liquid to positive pressure to separate particles of solid material such as protein, bacteria and viruses from the liquid.
Liquid free of solid particles, may be discharged from the assembly through a hypodermic needle that is removably secured to the assembly. A magnetically attractable body may rest on the filter within the interior of the assembly. When that body is subjected to a rotating magnetic field, the body moves concurrently with the field, and in so moving, the body removes caked, solid particles from the filter to facilitate the flow of liquid through the latter.
