摘要： An adsorbent medium is prepared comprising particles of a sponge material made of cellulose or agarose carrying functional groups such as diethylaminoethane groups. The particles may be obtained by chopping a larger block of the sponge material. The medium preferably has a water retention value of greater than 6 ml/g and a particle size of 0.5 to 10 mm, and the sponge material may be cross-linked. The adsorbent medium is especially useful for purifying DNA in an aqueous sample.

摘要： A fluid chamber and method are disclosed for filtering or separating particles. The fluid chamber includes a wall extending between an inlet and outlet to form a fluid chamber interior. The interior converges from a position of maximum cross-sectional area toward the inlet. A groove or a step may be formed on an inner surface of the fluid chamber wall to improve particle separation within the fluid chamber.

摘要： The present invention is directed to a method and system that separates first particles from second particles, or white blood cells from red blood cells, by sedimentation in a fluid chamber with debulking of one of the first or second particles or red blood cells through the inlet of the fluid chamber. The method and system further includes fractionation of the remaining particles or white blood cells into selected subsets. In one embodiment of the instant invention a blood product containing white blood cells is loaded in a separation chamber, a diluting or sedimenting agent is added to encourage rouleaux formation of any red blood cells, the cells are sedimented and the red blood cells are removed.
