[Nhcoll-l] Vat Issues

[Dirk Neumann]

Dear Heidi,

colleagues at the Natural History Museum in Berlin introduced large 
stainless-steel tanks used in large to store their canteen kitchens 
specimens in the fish collection. While these are movable (tanks with 
fixed wheels), London uses similar but much larger stainless-steel tanks 
for storage that are fixed to the ground.

In both cases, the cover of the tanks is designed in a way that a steel 
lip running inside of the lid near its outer margin neatly fits into the 
tank when lifting or closing the lid (like a drainboard), thus 
preventing condensing ethanol from direct contact with the gasket (which 
is fixed on a ledge running around the outer rim of the tank).

The movable canteen tanks have a bottom outlet plug which is apparently 
quite handy if you have to empty the tanks for any reason.

All the best
Dirk
