Abstract
A microscale sampling device including a frame is provided in the present invention, a sample container, a communicating channel and a resistance channel are defined in the frame. At least one sampling chamber is defined in the communicating channel. An end of the communicating channel is communicated with the sample container and the communicating channel is arranged below the sample container. An end of the resistance channel is communicated with the sampling chamber, and the other end of the resistance channel is communicated to an output joint. The resistance channel is shaped with at least one discontinuous shape change.
