• We recommend cleaning and refilling the pans 2 to 3 times a week. For evacuation, remove the
Permadry™ water pan.
• We recommend using distilled, sterile water to achieve optimum growth results. Any corrosive damage
that may arise following the use of water of different quality or by additives is excluded from the liability
agreement.
• If required, you can add microbiologically inhibiting substances such as copper chips, copper sulfate
or ethylene diamine tetra-vinegar acid (EDTA) in a concentration of 1 to 5 mmol/l.
Empty the Permadry™ water pan before moving the chamber. In case of the contents spilling,
immediately shut down the chamber and dry it carefully and completely.
