access icon free Horizontal connection method for glass microfluidic devices

In a conventional glass microfluidic system, the vertical connection is the most frequently used for connections between a microfluidic device and its peripheral equipment. However, it leads to a significant pressure drop at the inlet of a microfluidic device, decreases the flow velocity, and can introduce few samples than expected. To overcome these problems, a horizontal connection method for glass microfluidic devices, which have advantages such as keeping pressure/flow velocity, compatible with small space, reduced sample loss and convenience for modularisation is reported. These advantages are important for high-speed analysis on precious samples such as single-cell flow cytometry. In this work, they proposed a horizontal connection method which showed compatibility with high pressure (at least 0.6 MPa) at inlet without leakage, small loss of injected samples (<0.11%), and 22% faster flow velocity along the direction of applied pressure than that of vertical connection.
