Subject: Microfilm storage boxes
The most advanced microfilm box, from a preservation standpoint, is the MicroChamber box, which contains activated carbon and molecular sieves in addition to alkaline buffers. Alkaline buffers alone will not prevent the entry of oxidative and acidic gases, such as peroxides, SO2 or NO2. The MicroChamber box is very effective at capturing these compounds. It is also approximately 400 times more effective than the alkaline buffer calcium carbonate at dealing with acetic acid. You can purchase MicroChamber products from Conservation Resources or University Products.
