These paper petri dish filters can be used for extraction of crystalline materials or as a support medium for seed germination.  Before metabolic labeling, the disk can be placed in the top side of the 100 mm petri dish lid.  After the addition of the S-35 labeled amino acids to the cell culture fluid, the petri dish is covered with the lid-containing the activated charcoal disk.  The volatile radioactive compounds generated during the metabolic labeling are absorbed into the charcoal disks. Dispose in your regular beta waste. Use of the charcoal cartridges lessens the chance of breathing any volatiles and also reduces any contamination in the incubator. All of this media is designed to fit in a 100mm petri dish.
