The MicroSolv Zero and Controlled Flow CE capillaries are definitely compatible with the standard Beckman PA800 and MDQ capillary cartridges. These capillaries have a 360um OD and should have no issue with the standard cartridges.

NOTE: These capillaries are not precut to size nor do they have a detection window. This would be the responsibility of the user to properly place these capillaries into the cartridges.
