The present invention relates to a kit for the extraction buffy coat, and more particularly, the accuracy of the buffy coat extract relates to a kit for the buffy coat extracts maximizes the extraction amount of the buffy coat increase. To this end, the one end portion is engaged with an opening formed in a stepped insertion recess and the other end has a retaining part piston body so as to have a round hole formed bent toward the inside doedoe extends outwardly from the retaining part, so as to have a multi-stage bending inner peripheral surface formed in the extension portion disposed is seated in the engaging pieces of the body and the lifting member is formed on the bottom groove, the groove coupled to the opposite side of the lifting member and the piston comprises a sealing member for sealing an inner periphery of the body recesses of the elevation member a piston rod coupled to: a cylinder configured for extraction, including the buffy coat, to push the piston comprises a second rising device for rising, and the auxiliary device is raised case and a bevel gear provided inside of the case, gear assembly coupled to the bevel gear and including a screw provided in a vertical condition in the case and provided on the outside of the case, rotation means for rotating the bevel gear is coupled to the screw to be moved up and down by the forward, reverse rotation of the screw connection plate and elevating the outside in, the case of fixing the connection plate, which is coupled to the grooves of the vertical lifting axis member: a buffy coat provides for extraction kit comprising본 발명은 버피코트 추출용 키트에 관한 것으로서, 더욱 상세하게는 버피코트 추출에 대한 정확도를 높이고 버피코트에 대한 추출량을 극대화한 버피코트 추출용 키트에 관한 것이다.이를 위해, 일단부에는 단차진 삽입홈이 형성된 개구부가 결합되며, 타단부에는 내측을 향해 절곡된 걸림편의 둘레를 갖도록 피스톤공이 형성된 몸체상기 걸림편으로부터 외측으로 연장되되, 다단 절곡된 내주면을 갖도록 형성된 연장부상기 몸체의 걸림편에 안착되어 배치되며 저면에는 요홈이 형성된 승강부재와, 상기 승강부재의 요홈 반대측에 결합되며 몸체의 내주면을 씰링하는 씰링부재를 포함하는 피스톤상기 승강부재의 요홈에 결합된 피스톤 로드:를 포함하여 구성된 버피코트 추출용 실린더와, 상기 피스톤을 밀어 상승시키는 보조 상승장치를 포함하여
