96-channel automatic pipette, its assembly method and working method

Abstract

The present invention provides a 96-channel automatic pipettor, and an assembly method and operation method thereof, and an assembly method of an S-axis module includes the steps of fixing a first bakelite fixation to the inner side of an S-axis first side plate, and fixing a second bakelite fixation to the inner side of an S-axis second side plate; fixing a first S-axis hook plate to the inner side of the S-axis first side plate, fixing a second S-axis hook plate to the inner side of the S-axis second side plate, and connecting an S-axis lower plate between the first S-axis hook plate and the second S-axis hook plate; fixing an S-axis step motor flange between the ends of the S-axis first side plate and S-axis second side plate; passing four guide posts through the S-axis step motor flange, and positioning to the S-axis lower plate; connecting a square-hole frame to the ends of the four guide posts; fixing the S-axis step motor to the S-axis step motor flange through the square-hole frame. The 96-channel pipettor allows parallel extraction and split charging for 96 samples with good uniformity. Manual liquid division time is greatly shortened, and error rate is very low.

Description

technical field [0001] The invention is applied in the medical industry, and particularly relates to a 96-channel automatic pipette for parallel extraction of 96 samples, an assembly method and a working method thereof. Background technique [0002] A pipette is a routine laboratory instrument used to facilitate our users to pipette liquid samples. The principle of the pipette is very simple, that is, the piston moves up and down by the stretching force of the spring to discharge or absorb liquid. [0003] Generally speaking, there are two types of pipettes, one is the air displacement type; the other is the external piston type, which is often used as a special pipette with a narrow application range. This type of pipette can be used For pipetting highly viscous samples. [0004] The air displacement type is to press down the piston to press out the air inside the lower end of the pipette, and then when the piston moves up, the air pressure inside the lower end of the pip...

Problems solved by technology

[0008] At present, most liquid pipetting devices on the market either have insufficient processing throughput, or the operating cost is too high, and the cost performance is low, which cannot satisfy most researchers.
