Problems solved by technology

[0004] However, when the solution is pipetted using the syringe, the solution components or reaction products leak from the syringe to the suction / spray nozzle side through the aerosol, causing contamination or external contamination.
In addition, conversely, the solution to be pipetted is sometimes contaminated by aerosols inside the pipette

Embodiment Construction

[0077] Figure 1A , 1B is a reaction instrument kit representing an embodiment, Figure 1A is the vertical profile, Figure 1B is a top view showing the reaction plate and the transfer device 20, figure 2 is a perspective view of this embodiment. Such as Figure 1A As shown, the reaction plate 2 includes, on the surface side of the substrate 3 , a reaction container 4 for reacting a sample, and a reagent container 12 for storing a reagent used in the reaction of the sample and sealing it with a thin film 14 .

[0078] The reaction vessel 4 is provided as a recess on the surface of the substrate 3 . When the temperature of the reaction vessel 4 is controlled from the outside during the reaction, it is preferable that the wall thickness of the reaction vessel 4 is thin in order to improve the thermal conductivity.

[0079] The reagent container 12 is constituted by a plurality of recesses formed in the substrate 3 , necessary reagents are accommodated in these recesses, and ...

Abstract

To prevent aerosol in a dispensing tip from contaminating the outside of the tip and a solution to be dispensed. The dispensing tip (20) has a dispensing nozzle (19) positioned at its forward end, a syringe connected to the base end of the dispensing nozzle (19) and having a cavity therein, and a plunger (22) for performing suction and discharge of a liquid from the dispensing nozzle (19) by sliding in the cylinder (21) of the syringe. A separating member is placed between the base end side of the plunger (22) and the base end side of the cylinder (22), and the separating member has airtightness separating the inside of the nozzle (19) from the outside and flexibility allowing the plunger (22) to slide over the separating member.

Description

technical field [0001] The present invention relates to a transfusion device suitable for performing various analysis or analysis in medical or chemical fields in the general field of biological analysis, biochemical analysis, or chemical analysis, a reaction instrument kit using the same, and a transfusion device driving mechanism . Background technique [0002] As a small reaction device used in biological analysis or general chemical analysis, a micro multi-chamber device is used. As such a device, for example, a microwell reaction plate such as a microtiter plate having a plurality of wells formed on the surface of a flat substrate is used. [0003] In addition, a hollow conical dispensing tip with a tip is used as a dispensing tip attached to the tip of a suction / discharging nozzle for pipetting a solution such as a sample or a reagent in these reaction devices. . [0004] However, when the solution is pipetted using the syringe, the solution components or reaction p...
