Cross-channel wafers include a variety of cross-channel wafers with T-shaped or double-T-shaped structures. Different sizes are possible, from the microscope slide format of 25.5 mm × 75.5 mm to extended platform sizes of 95.5 mm × 16 mm × 1.5 mm or 141 mm × 16 mm × 1.5 mm. The maximum standard channel length available is 120 mm. The maximum standard channel length available is 120 mm, which can be filled as a fluidic interface using a simple through-hole connector and a pipette or female Luer adapter. One of the most common applications for this wafer class is capillary electrophoresis.
