5‑50 µl 60-Tip Pipette

Abstract

The invention discloses a pipette with 5-50 microliters and 60 tips, which belongs to the technical field of analytical chemical equipment. The four corners of the base plate are respectively provided with mutually perpendicular holes, the lower ends of the holes are equipped with feet, and the upper ends are equipped with columns and bolts. The lower end of the foot passes through the hole of the bottom plate to connect the lower end of the column; there are three through holes in the longitudinal middle of the bottom plate, the middle through holes are connected to the liquid tank by bolts, and the positioning pins at the lower end of the liquid tank are inserted into the through holes on both sides; the liquid tank There are deep liquid tanks and shallow liquid tanks inside; there is a tip holder on the upper end of the liquid tank, and there are 60 through holes in the tip holder, and the distance between each through hole is 12mm; the structure of the tip assembly is: The seat is rectangular, with 6 rows of through holes drilled longitudinally in the middle, and 1 row of through holes drilled horizontally. The longitudinal through holes and the horizontal through holes are vertically intersected and communicated with each other. There is a central trachea installed in the middle of the upper end perpendicular to the intersection point. As for the threaded holes, 60 holes for installing the suction heads at a distance of 12 mm are drilled at the lower end of the 6 rows of through holes perpendicular to the longitudinal direction.

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...
