Abstract
A device for separating particulate matter (e.g., cells) from a liquid including a housing defining an elongate chamber disposed between a receiving end and a dispenser end, a plunger slidably inserted within the chamber from the receiving end, an upper disc and a lower disc each independently slidably affixed to the plunger, the lower disc facing the dispenser end and including at least one filter arrangement, and a liquid including particulate matter disposed within the chamber when the upper disc and lower disc are in an aspiration mode. The upper disc is independently slidable with respect to the lower disc to achieve a filtration mode.

18. A method for separating particulate matter from a liquid comprising:
- providing a housing defining an elongate chamber disposed between a receiving end and a dispenser end;
providing a plunger slidably inserted within the chamber from the receiving end;
providing an upper disc and a lower disc each independently slidably affixed to the plunger, the lower disc facing the dispenser end and including at least one filter arrangement;
sliding the upper and lower discs upwards towards the receiving end for aspirating a liquid including particulate matter within the chamber;
affixing a cap to the dispensing end; and
sliding the lower disc downwards to achieve a filtration mode for separating the particulate matter from the liquid so as to cause the upper disc to slide toward the receiving end. - View Dependent Claims (19, 20)
