Note:

1 Evaporation rate and holding time are nominal. Actual rate may be affected by the nature of the contents, atmospheric conditions, container history and manufacturing tolerances.
2 Working time is an arbitrary, reference-only value to estimate container performance under the actual operating conditions
3 Without canisters.
4 The roller base increases the overall height of the vessel by 110mm.
