(1) Evaporation rate and static holding time are nominal. Actual rate may be affected by the nature of the contents, atmospheric conditions, container history, and manufacturing tolerances.
(2) Work time is an arbitrary, reference-only value to estimate container performance under the actual operating conditions. Actual working time may vary widely depending on individual use patterns.
(3) Without canisters or racks.
(4) Optional 7th canister available to increase storage capacity by 23%
