The Flinn Suggested Chemical Storage Patterns have been adopted by science teachers across the United States. The Flinn Suggested Chemical Storage Patterns have now been enlarged and are available as 11" wide x 17" high wall charts. Post these charts in the school chemical stores area to provide a ready and durable reference for your day-to-day needs. Two charts are included. The first includes the ten inorganic families and the second has the nine organic families. The charts are made of very durable stock which is heavily laminated.
