Filtration is a key step to maximize singlets and prevent clogs during flow cytometry. Holding the sides of the mesh to keep it taut while pressing gently against the mesh with the pipette tips allows the liquid to travel through the mesh and into the wells. If the liquid accumulates on top of the mesh, it can mix with and contaminate neighboring wells.
