Principle of OT-2 pipetting workstation

OT-2 is a desktop-level automated pipetting platform with hardware modularity, flexibility and customization, and can realize the advantages of automating many common applications. It can be equipped with both single-channel and 8-channel pipettes to meet the precise pipetting of 1-1000 μl. When OT-2 absorbs 1 ul of liquid, the accuracy CV value is ±5%, and the pipetting accuracy is comparable to pipetting equipment that is 10 times more expensive on the market.

1. Equipment principle

The OT-2 automated pipetting station adopts advanced technology and intelligent control system, and is mainly composed of three parts: pipette, workbench and control system. The pipette is its core component, capable of precisely controlling the aspiration, transfer and release of liquids. The workbench provides a stable working environment to ensure the accuracy and stability of pipetting operations. The control system is responsible for the automated operation of the entire equipment, including pipetting path planning, speed control, data recording, etc.
