Aerotron
 

The Aerotron is a small, compact orbital incubator shaker for almost every sort of application. The hood has two gassing ports, so allowing the unit to be gassed or operated under a slight negative pressure. Liquid spillages from a flask breakage can be collected in the base of the chamber and drained via a bottom valve. The sealed base can also act as a reservoir for liquid to allow operation with humidification. On the basis of its closed construction and ease of cleaning, this makes the unit very suitable for applications involving issues of biological safety.
