At the Zoological Museum of Amsterdam (Z.M.A.) of the university of
Amsterdam, we have some negative experiences with compactor-units
and wet collections. Depending on the quality of the units, and
their smooth movement, there might be vibration that may cause
(tall) containers to topple over. Also the vibration may damage the
sealing of the container lids, and the fluid could evaporate
unnoticed. This can happen especially with older and dried-up
sealing material. The closed character of the units obstructs easy
inspection as opposed to open storage.
