Liquid medium dispensing device

Abstract

Disclosed is a liquid culture medium subpackaging device.The liquid culture medium subpackaging device comprises a dispensette and is characterized by further comprising a connecting hose, a liquid cyclone and a support, wherein a liquid inlet of the liquid cyclone is communicated with a liquid outlet of the dispensette through the connecting hose, liquid split-flow outlets of the liquid cyclone face downwards and are identical with transversely-arranged or longitudinally-arranged cell culture holes of a cell culture plate in number, the liquid cyclone is supported on the support, the cell culture plate is disposed below the liquid cyclone, and the liquid cyclone or the cell culture plate can slide horizontally along a direction perpendicular to a connecting line of the liquid split-flow outlets of the liquid cyclone, so that different transversely-arranged or longitudinally-arranged cell culture holes of the cell culture plate can correspond to the liquid split-flow outlets of the liquid cyclone.The liquid culture medium subpackaging device is capable of not only subpackaging liquid culture medium into the cell culture plate efficiently and quickly but also reducing waste of the liquid culture medium and experiment cost.

Description

technical field [0001] The invention relates to the technical field of cell culture, in particular to a liquid medium subpackaging device. Background technique [0002] As an important tool in high-throughput culture technology, cell culture plates have been increasingly used in the field of biomedicine. When dispensing liquid medium to cell culture plates, the traditional method is to operate through bottle-top dispensers or pipette guns, but bottle-top dispensers and pipette guns are single-channel dispensing equipment, and the dispensing efficiency is low , The time is long, the probability of infection is high. As a result, multi-channel pipettes emerged as the times require, which can quickly and parallelly distribute liquid culture media to cell culture plates. On the other hand, it must be equipped with a sampling tank compatible with the multi-channel pipette tip. In order to ensure that the multi-channel pipette can accurately and effectively absorb the liquid med...

Problems solved by technology

When dispensing liquid medium to cell culture plates, the traditional method is to operate through bottle-top dispensers or pipette guns, but bottle-top dispensers and pipette guns are single-channel dispensing equipment, and the dispensing efficiency is low , long time, high chance of infection

As a result, multi-channel pipettes emerged as the times require, which can quickly and parallelly distribute liquid culture media to cell culture plates. On the other hand, it must be equipped with a sampling tank compatible with the multi-channel pipette tip. In order to ensure that the multi-channel pipette can accurately and effectively absorb the liquid medium, the liquid medium poured into the sampling tank is beyond the actual demand, which will lead to waste of liquid medium and high experiment cost
