Absorb Incubator Contaminants This disposable, activated charcoal cartridge efficiently absorbs low energy 35S radioactive components during metabolic labeling. The containment problem exists in incubators and is caused by 35S-labeled amino acids, such as methionine and cysteine which are used to label proteins. The charcoal is supplied in a 100 mm diameter plastic petri dish with a highly porous membrane sealed to the top edge.
