ABSTRACT:
A separation-science disc dispenser (10) has a storage chamber (12) disposed normally to a base (20) that possesses a slot (24) into which a slidable member (26) resides. The storage chamber (12) contains disc units (14) that include a separation-science membrane (16) and a protective liner (18). Where the storage chamber (12) meets the base (20), there is an opening (30) in the storage chamber that allows disc units (14) to exit the storage chamber. The slidable member has a cavity (28) sized to receive a single disc unit (14) from the storage chamber (12) when the cavity (28) is in register with the opening (30). Drawing the slidable member (26) outward from slot (24) causes a single disc unit (14) to be discharged in a non-contaminated condition from the dispenser (10).
