Hello All,
                   We are looking to buy a stage top incubator. However, 
one of the questions which has come up is whether the gases are running 
continuously to maintain levels since it is open near the objective.
Are there gaskets to seal around slides/petri dishes so that a feedback 
on the levels can be provided and the gas flow can be upregulated or 
downregulated depending on the need.   Finally, most of them
have a bottle of water for humidifying the chamber. Only Tokai Hit has 
tray with water in the insert itself. Any thoughts on the pros/cons is 
appreciated.

Any other feedback to help us make a sound decision will be great.

Thanks,

-Prabhakar
