Description and Features Body preservation cuvette (tank) with downdraft extraction for use in gross antomy & embalming The cuvette for the preservation of body donors (dip system) has been developed for use in the gross anatomy. The preservation media maybe freely choosen (including ethanol), because the height adjustment of the insert is electrically driven with an explosion protected switch. The system therefore meets all requirements of an explosion-proof environment. The switch UP / DOWN is of explosion- proof design.
