Abstract

The invention discloses a 5-50 microliter 60-sucker liquid transfer device and belongs to the technical field of analytical chemical equipment. Mutually perpendicular holes are respectively formed in four corners of a base plate, bottom feet are installed at the lower ends of the holes, columns are installed at the upper ends of the holes, and bolts penetrate through the holes formed in the base plate from the lower ends of the bottom feet to be connected with the lower ends of the columns. Three through holes are respectively formed in the longitudinal middle of the base plate, the middle through hole is connected with a liquid tank through bolts, and positioning pins at the lower end of the liquid tank are inserted into the through holes formed in two sides. A deep liquid tank and a shallow liquid tank are respectively located in the liquid tank. A sucker frame is installed at the upper end of the liquid tank, 60 through holes are formed in the sucker frame, and the spacing of every two adjacent through holes is 12 mm. A sucker assembly is structurally that a sucker seat is a rectangle, 6 rows of through holes are dilled in the middle in the longitudinal direction, one row of through holes is drilled in the horizontal direction, the longitudinal through holes are crossed and communicated with the horizontal through holes in a mutually perpendicular mode, a threaded hole for installing a main air pipe is formed in the middle of the upper end perpendicular to the cross points, and 60 holes which are spaced at intervals of 12 mm and used for installing suckers are drilled in the lower end perpendicular to the 6 rows of longitudinal through holes.

Description

technical field [0001] The invention relates to a pipette with 5-50 microliters and 60 suction tips, which belongs to the technical field of analytical chemical equipment. Background technique [0002] At present, in the known micro-analytical chemistry experiments, when adding reagents or indicators to the test tubes on the micro-test tube rack, the dropper, single-tip pipette or single-row pipette multi-tips are added drop by drop, so the operation speed is slow. The single-tip pipette is a friction structure of the piston and the fixed sleeve, which is easy to wear, has a limited number of uses, and has a short life. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a 5-50 microliter 60-tip pipette, which can use the liquid level difference to determine the amount of inhaled liquid as required. [0004] The technical solution of the present invention is: 5-50 microliters 60 tip pipettes, the structure is: th...
