High Contents Screening을 위한 비접촉식 고정밀 디스팬서 제작

Nowadays medical treatment service increase due to ageing population and improving the quality of life. Accordingly it is predicted that drug discovery market will expansion continuously. Therefore it is necessary that profit creation by drug discovery on the global market is important. HCS(High Content Screening) has been emerging as a potential method to solve problems of the present drug discovery. This research is about liquid dispenser for HCS. The purpose of this research is to manufacture high performance liquid dispenser for HCS. The liquid dispenser for HCS has to satisfy several conditions; fast, precision dispensing, dispensing of various kind of liquid at once, and being disposable, biocompatible, and chemically inert on the part of contact with liquid. To satisfy these conditions, several works were performed; the pressure driven pump was developed because there were many disadvantages on syringe pump to control very small liquid volume. The dispenser is designed to control 5 liquids separately. HCS system has to use many kinds of liquids and control dilution ratio between liquids. The liquid contact parts are designed disposably, biocompatibly and chemically inertly. Air curtain is equipped at the side of tip to dispense very small liquid volume and to prevent hanging drop on tip. Valving is performed by just controlling the pressure of the pressure driven pump without valve. Therefore, problems occurring while using valve are solved. As a result of these works, liquid dispenser for HCS is completed.
