Abstract

The invention discloses a multi-channel liquid dispensing device and a liquid dispensing method based on microfluidic printing, and relates to the technical field of laboratory high-throughput precision liquid volume distribution and biochemical analysis instruments. The invention includes an L-shaped mounting plate, an L-shaped mounting seat is fixed on one side wall of the L-shaped mounting plate that can be lifted and lowered by a manual displacement table; two pillars are installed on the end of the L-shaped mounting plate, and the end faces of the two pillars are A crossbeam is connected; at least one piezoelectric actuator is arranged on the L-shaped mounting plate; microfluidic chips cooperating with the piezoelectric actuators are arranged on the crossbeam. The invention solves the problems of high-throughput generation of volume-consistent micro-droplets and the problems of multi-channel parallel clamping and alignment.

Description

technical field [0001] The invention belongs to the technical field of laboratory high-throughput precision liquid volume distribution and biochemical analysis instruments, and in particular relates to a multi-channel liquid dispensing device and liquid dispensing method based on microfluidic printing. Background technique [0002] In biochemical experiments and industrial production, it is often necessary to operate liquid reagents for quantitative and rapid distribution. The traditional pneumatic and printing dispensing methods can realize rapid quantitative distribution of microliter and submicroliter liquid reagents. The current products are: Eppendorf's Product range, Tecan's Freedom Product series and D300e digital dispenser, etc. Traditional liquid dispensing equipment mainly increases the throughput of liquid dispensing by increasing the number of liquid dispensing channels or the number of print heads, and the volume consistency of droplets generated between di...
