We introduce a novel technique to produce monodisperse droplets through the snap-off mechanism. The methodology is simple, versatile, and requires no specialized or expensive components. The droplets produced have polydispersity < 1% and can be as small as 2.5 μm radius. A convenient feature is that the droplet size is constant over a 100-fold change in flow rate, while at higher flows the droplet size can be continuously adjusted.
我们介绍了一种通过液滴断裂机制产生单分散液滴的新技术。该方法简单、通用，无需特殊或昂贵的组件。所产生的液滴多分散性<1%，半径可小至2.5μm。一个便利的特点是，在流速变化100倍的情况下液滴尺寸保持恒定，而在更高流速下液滴尺寸可连续调节。
