New description: [New technical field] The present invention relates to a micro-absorber, in particular to a micro-absorber for sucking a small amount of liquid. [Prior Art] In the dropout, biological or chemical experiments, the sampling amount of the reagent is quite small, and any slight error is likely to have a great influence on the experimental results, and the micropipet is a biochemical experiment or molecule. An essential tool for biological experiments, which is used to absorb trace amounts of liquid or sample. The amount of absorption is mostly in units of /ZL (10-6L), so the correctness of the method of use and the accuracy of the micropipette are directly affected. The correctness of the experimental results. However, since many experiments need to be protected from light or low light, the solution to be sucked is not afraid of light, but because other test solutions cannot illuminate, such laboratory environment light is usually insufficient, even in the case of light, but in the case of reflection. When the micropipette is used for suction, it is often impossible to accurately insert the bottom end into a predetermined height below the liquid surface, which often causes an error of bubble generation and insufficient mixing, and it is easy to cause a solution suction error, which will eventually cause deviations in the experimental results. As the accuracy of micro-absorption in the laboratory is getting higher and higher, how to effectively develop products that meet customer needs has become one of the most important topics in product development today. [New content] Therefore, the purpose of the present invention is to provide a micro-absorber that emits light for liquid extraction. Thus, the novel micro-absorber comprises: a grip tube device, a three-piston device, a control device, and a light-emitting device.

Each display member 311 is arranged in a class. For the number of 〇~9, the experimenter can use the number of the window 11 ' η ^ ^ material table (four) to absorb the amount of liquid 5 M381462. The knob 33 is located in the open space 14 for the fingers to be rotated. The miscellaneous rod 34 has a button portion 341 formed at the tip end and projecting beyond the grip tube device i, and - abutting against the piston rod 22 to drive the pressing portion 342 of the piston device 2. Rotating the knob 33 causes the screw 32 to drive the counting unit it 3i ’ so that the display member 311 correspondingly displays the rotated number. The culling device 4 is mounted on the grip tube assembly and includes a ejector rod 41 movably sleeved on the grip tube body u and abutting against the top side of the suction tube sleeve 12, and a movably mounted The pressure-removing unit 42 of the pick-up rod is driven in the grip body. Since the structure of the pressure-removing unit 42 is not the focus of the present invention, it will not be described in detail herein. Pressing the press-off unit it 42 can drive the The rejecting rod 41 moves downward to push the suction tube sleeve 12 to be removed from the bottom end of the holding tube body 1. The light-emitting device 5 is mounted on the body u of the returning device, and includes three separate parts. a light-emitting body 51, a power source 52 for supplying power to the light-emitting body 51, and a switch 53 for controlling whether the power source 52 and the light-emitting body 51 are turned on or off. The light-emitting bodies 51 are all light-emitting diodes. The number and color of the illuminants 51 can be increased or decreased according to the design requirements. In addition, due to the connection circuit of the illuminant 51, the power source 52 and the switch 53, the related opening and closing, adjusting brightness, and position or shape design are not the present invention. Focus, so no longer here In use, the suction sleeve 12 is tightly axially mounted on the bottom end of the grip body 11 and then the knob 33 is rotated to drive the screw 32 and interlock the counting unit 31 to display the display member. 31丨 corresponds to the number after the transfer is displayed until it is moved to the amount of liquid to be sucked. 6 M381462 Next, as shown by the arrow 6 in FIG. 3, the lever 34 is pressed down, and the piston rod 22 is pressed to drive the piston. 21 is moved downward to discharge the local air in the liquid absorbing space 15 while the elastic unit 23 has a reset elastic force. The suction tube sleeve 12 is vertically immersed under the liquid surface by 2 to 6 mm, and then the control rod 34 is slowly released. By the elastic force of the elastic unit 23, the piston 21 is moved up to the position shown in FIG. 2, and vacuum suction is generated to draw a small amount of liquid into the liquid absorbing space 15, waiting for 丨~2 seconds after the suction The sleeve 12 is pulled away from the liquid surface to complete the liquid taking operation. When the liquid is to be filled, the bottom end of the suction tube sleeve is inclined by 1 〇 to 45 degrees on the inner wall of the container (not shown), and then Slowly press the lever 34 to the appropriate height, waiting for 1~2 Then, the control rod 34 is all pressed down to discharge the liquid in the suction tube sleeve 12. The suction tube sleeve I] is slid up and away from the container along the inner wall of the container, and finally the control rod 34 is completely released. When the light is insufficient or reflective, the switch 53 is turned on, so that the illuminant 51 emits light, generates partial light, and provides appropriate illumination, so that the experimenter can clearly perform the liquid picking operation, thereby improving the precision of the experiment. The suction solution cannot be illuminated, and the present invention is not applicable. In summary, the present invention mainly installs the hair device on the holding device 1 to generate sufficient light shell to increase the clarity of the experimenter's line of sight. It can improve the accuracy of the experiment and make the experiment that needs to be protected from light smoothly. Therefore, it can achieve the purpose of this new type. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel description content, All still 7 M381462 is covered by this new patent.
