Abstract

A new multifunctional device is presented for the first time dosing liquids of high precision in the range of a few picoliter up to 230 nanoliter by a single free liquid jet. In contrast to the working principle of ink jet heads the device is comprising two operating modes, the novel high dynamic volume ejection for nanoliter dosage, named LiquiJet-Mode, in addition to the acoustic wave technique of ink jet heads used for picoliter dosage (LiquiDrop-Mode). The device has been realized and successfully tested with liquids in the viscosity range from 1 mPas to 80 mPas.

一种新型的自由射流多功能液体加药装置

本文首次提出了一种新型多功能装置，可通过单个自由液体射流对几皮升至230纳升范围内的高精度液体进行定量。与喷墨头的工作原理相反，该装置包括两种工作模式，一种是用于纳米升剂量的新型高动态体积喷射(LiquiJet-Mode)，另一种是用于皮升剂量的喷墨头的声波技术(liquiddrop - mode)。该装置已经实现，并成功地测试了粘度范围从1 mPas到80 mPas的液体。
