Capillary Diameters

Capillary arrays are available with common capillary diameters of 5, 10, 25, 50, and 100Ám. Custom diameters ranging from sub-micron to several millimeters in diameter can also be produced.

CHI can redraw individual glass tubes to any size between 25Ám and the preform's original diameter. In drawn multi-tube structures, the constituent tubes commonly have interior diameters of a few microns up to a millimeter.
