Description

Technical Field

[0001] The utility model relates to the technical field of liquid sample adding auxiliary equipment, in particular to a sample adding auxiliary device for a cell culture plate. Background Art

[0002] In the process of cell culture, the pipette device is an indispensable tool, among which the pipette has an important position in cell culture because of its advantages of convenient use and relatively accurate measurement. In a cell culture, the pipette uses more specifications, so the pipette is usually placed on a stand to avoid problems such as taking errors and confusion in use, and to improve the efficiency and accuracy of pipetting; it can be seen that the pipette stand is extremely useful as a sample addition auxiliary device in cell culture. However, in the actual use process, the number of times the same substance is added may be more than once. Therefore, in order to reduce the waste of the gun tip, the gun tip on the pipette may be used multiple times, and the gun tip will inevitably be attached with liquid. When placed on the pipette stand, the problem of liquid dripping onto the base of the pipette stand may occur, causing pollution; in addition, the gun tip that is not reused needs to be placed in the waste collection place, and in actual operation, a waste liquid box or other non-fixed storage container may be used, which is prone to dumping and spilling; that is, it is of great significance to provide a sample addition auxiliary device that can prevent liquid from contaminating the base of the pipette.
