The cathode buffer container (CBC) contains 1X running buffer to support all electrophoresis applications on Applied Biosystems 3500 and SeqStudio Flex series genetic analyzers. The container has two separate compartments, the left side provides the cathode buffer for electrophoresis and the right side provides for a capillary wash and spent polymer waste ejection functionality between injections.

The CBC is made in a ready-to-use, disposable container with a radio frequency identification (RFID) tag incorporated into the label. The top of the CBC is heat sealed with a plastic film, which should be removed prior to direct installation on to the instrument. Each package includes four individual containers.
