Abstract: A reagent reaction container includes a container body having a plurality of receiving bores through top and bottom sides thereof, a plurality of filter holders mounted in the receiving bores respectively and each having a through hole through top and bottom sides thereof and an engagement portion engaged with a periphery wall of the respective receiving bore, a plurality of drain elements mounted in the through holes of the filter holders respectively, and a plurality of filters respectively mounted in the through holes of the filter holders and supported on the respective drain element. The drain element has a crevice that is closed when the drain element receives no pressure and is opened when the drain element receives a predetermined external force.

Abstract: A liquid dispenser includes a dispenser body having a liquid input passage extending inwardly from the top side of the dispenser body, a liquid distribution passage formed inside the dispenser body in communication with the liquid input passage, two liquid output passages each having a first side respectively connected to the liquid distribution passage and a second side provided with a plurality of outlets, and an air output passage in communication with the liquid output passages. A plurality of needle cannulas are respectively fastened to a bottom side of the dispenser body and respectively connected to the outlets of the liquid output passages. When liquid is filled inside the dispenser body, the air initially contained inside the dispenser body will be forced by the liquid to be discharged out of the dispenser body through the air output passage.

Abstract: A shaking mixer includes a first transmission rod set, a first driving motor for rotating the first transmission rod set; two first synchronous transmission members respectively spacedly coupled to the first transmission rod set for synchronous movement upon rotation of the first transmission rod set, a second transmission rod set, a second driving motor for rotating the second transmission rod set, two second synchronous transmission members respectively spacedly coupled to the second transmission rod set for synchronous movement upon rotation of the second transmission rod set, and a moveable platform having two rods arranged in a crossed manner and respectively connected to the first synchronous transmission members and the second synchronous transmission members for oscillation on a plane freely.
