The present invention may include an upper cap having an opening/closing member for opening and closing an inlet through which a blood is injected; a main body housing having an open upper end outer surface thereof assembled with the upper cap, and having an inner space in which the blood is filled with; an adjustment housing that is coupled to the main body housing to seal the open lower end of the main body housing, and is movably assembled with respect to the main body housing so that a buffy coat layer is positioned on a neck portion; and a side cap fixed to the neck portion by forming a needle hole through which an end of an injection needle for extraction enters and exits in area corresponding to a sealing member to seal an extraction hole formed through the neck portion.

Automated method for leukocyte collection from whole blood

The present invention relates to a method for separating lymphocytes and/or stem cells from whole blood in an automated blood separation system, wherein the quality of the collected lymphocytes and/or stem cells fractions is increased and the cell collection procedure is further automated by use of an optical sensor comprised in a detector device to measure turbidity and colour in the claimed method and in a cell separator, which can be used to perform the claimed method. The method of the invention is particularly useful to collect lymphocytes and/or stem cells fractions from whole blood, wherein the contamination of the collected cell fractions by platelets, red blood cells and granulocytes is reduced.

Tissue processing apparatus and method for processing adipose tissue

A method for processing biological material containing stringy tissue in a container having a tissue collector disposed in a tissue retention volume on one side of an internal filter includes washing biological material contained in the tissue retention volume with wash liquid to the tissue retention volume and allowing the wash liquid and rotating the tissue collector disposed in the tissue retention volume relative to the container in a first direction of rotation about an axis of rotation to sweep the teeth positioned on the tissue collector through the biological material and to collect stringy material on the tissue collector.
