A disposal reaction module for providing a small amount of test agent to mix with a reaction agent for testing use. The module include a reaction chamber fluidly communicating with at least one test agent room. A piston in a gate room is located between the reaction chamber and the test agent room for controlling flow of test agent to the reaction chamber. The module may be made small size and portable to facilitate carrying. It is especially convenient and useful for field test use. People may do the test without direct contact with the reaction and test agents, and thus is safer to use than conventional method of using testing glasses and tubes.

Method of manufacturing disposable reaction module

A system is designed to measure the concentration of a specific chemical composition of a fluid and is formed of a light generating device, a fluorescent light receiver, and a display. The light generating device emits an excitation light to cause a probe submerged in the fluid to emit fluorescent light, which is received by a photoelectric diode of the fluorescent light receiver and is than converted by the photoelectric diode into an electric current signal. The display receives the electric current signal, which is then converted by the display into the concentration of the specific chemical composition of the fluid. The information on the concentration of the specific chemical composition is exhibited on the display.

System for measuring concentration of chemical composition of fluid

This invention relates to a disposable reaction module, capable of permitting small amount of test agents to mix with a reaction agent, having at least one test agent room, a reaction chamber capable of making fluid communication with said test agent rooms, and at least a gate room, situated between the reaction chamber and the corresponding test agent room. A piston is provided for controlling the flow of test agent into the reaction chamber. Being portable, the module is suitable for field test applications, especially without direct human contact, the module offers safer operations over those using conventional tubes and glasses.
