Abstract: |
Belonging to fluid control technical area of biochip, the disclosed micro liquid cavity is in use for preventing liquid form flowing along wedge angle of tube wall inside hydrophilic microcapillary. Characters are that the cavity is an extended cavity relative to the portion of containing at least one wedge angle, or entire section of pipe; the cavity is larger enough to break continuous extension of wedge angle along direction of pipe. Moreover, there are multiple cavities arranged along direction of pipe with stagger certain distances. Practice proves that micro liquid cavities break wedge angle formed by crossed wall faces so that it is easy to control flow of liquid inside microcapillary. |
