How is it possible to eliminate the water tray from my incubator?

Post

Standard plates, dishes and flasks must be open to allow open CO2 gas exchange. The Petaka G3™ is functionally closed and retains CO2 in culture automatically. All liquid transfers are performed through a closed, sterile silicone port. In addition to benefit of reduced contamination risk during processing, the closed design means that media evaporation is practically eliminated. This is why there is no need to maintain a water tray inside the incubator. This eliminates a second major contamination source.

The Petaka G3™ has been shown to minimize evaporation loss in culture even at extremely low ambient humidity levels.
