Capillary Flow Cells

          Capillary Flow Cells for microscopy are designed to image biofilm formation in glass capillaries under a wide range of flow rates and surface shear conditions. These flow cells use square glass capillaries as viewing windows and flow channels. Each flow cell holds 4 glass capillaries in a capillary holder. The range of flow rates through the capillaries is much wider than is allowed in the flat plate flow cells. Fluid flow characterization from laminar to turbulent flow can be achieved in the glass capillary channels.
