摘要:
At least one of a nucleus forming process, a nucleus growing process, a chemical sensitizing process, and a spectral sensitizing process for producing a silver halide photographic emulsion is performed by using a microreactor. A minute region of the microreactor is used to precisely perform a reaction of nucleus formation. A condition under which host grains are allowed to react with newly supplied silver halide nuclei is made uniform to cause uniform crystal growth. A predetermined quantity of molecules for chemical sensitization is doped in a crystal lattice of a nucleus of silver halide to effect a sensitizing process. Alternatively, a spectral sensitizing process in which a single molecular layer of a spectral sensitizer is uniformly adsorbed on a silver halide nucleus grain surface is securely carried out.

According to a blood plasma collection tool of the present invention, a phenomenon that blood cells in blood spontaneously precipitate due to an effect of gravitational force takes place in the very narrow microspace (separation part) having the very narrow depth in the direction of gravitational force of not greater than 1 mm, and the overflow channel functions as a dam against the separation part so that the blood plasma separated out as supernatant fluid can overflow beyond the overflow channel, whereby the blood cells separated out can be prevented from entering the collection part. Therefore, blood plasma can be collected by accurately and readily separating blood plasma and blood cells in a small amount of blood from each other in a short time, using a small tool having a simple structure.

The present invention provides a reaction method for a reaction system generating gas by a reaction, comprising the steps of: providing a sealed mixing section for mixing a plurality of liquids to start a reaction and a degassing section having a gas-liquid interface for removing, from a reaction liquid, gas bubbles generated from a mixed reaction liquid, separately; and feeding the reaction liquid mixed in the mixing section to the degassing section, without being interfered by gas bubbles even in a reaction system where gas is generated by a reaction, so that it is possible to stabilize a reaction at the start of the reaction and in the progress of the reaction and stably feed liquid to a subsequent process.
