Abstract: A microtube assembly includes a column container, a sealing cap and a collecting tube. The column container includes a column body having a first protruding structure, and the one end of the column body has an opening and a first outer thread. The sealing cap has an inner thread matching up with the first outer thread, and the sealing cap is sealed the opening of the column container by the inner thread screwed on the first outer thread of the column body. The collecting tube includes a collecting tube body having a containing space and a matching structure corresponding to the first protruding structure. The containing space is configured for containing the column container. The matching structure leans against the first protruding structure when the sealing cap seals the column container.

Abstract: A pickup and contact device is adapted to be connected to a moving device to move a picked-up electronic element to an electrical testing zone. The moving device pressurizes the electronic element through the pickup and contact device, so that a contact point of the electronic element stably contacts a contact pad of the electrical testing zone. The pickup and contact device includes a main body including a base and a contact portion and a plurality of heat dissipation fins disposed at two opposite sides of the base. The contact portion is adapted to pick up the electronic element and to move the electronic element to the electrical testing zone along with the moving device. When the electronic element is tested in the electrical testing zone, heat emitted from the electronic element is adapted to be transmitted out through the heat dissipation fins of the main body.

Abstract: Provided is a method for preparing 2-cyclohexyl cyclohexanol, including: hydrogenating a cyclohexanone dimer with hydrogen gas at a temperature ranging from 150 to 250° C. in a reactor containing a catalyst to prepare 2-cyclohexylcyclohexanol, wherein the molar ratio of the hydrogen gas and oil ranges from 1 to 25. The method has advantages of high yield properties and allows for mass production, thereby enhancing the value of the industrial application.
