1. A bioreactor exhaust assembly comprising:
- (a) an exhaust tube with an inner volume and a lower end connected to a bioreactor and an upper end connected to a low pressure relief valve and a plurality of sensors including at least a pressure sensor and a temperature sensor;
(b) wherein the exhaust tube is cooled to maintain a temperature below the dew point of a gas in the exhaust tube; and
wherein the exhaust tube is attached to a vertical surface, held up by a hook at a higher elevation or winding it upward around a vertical cylindrical block with an outer surface.

Abstract
An exhaust system suitable for high volume exhaust from flexible disposable bags is described that prevents nutrient media volume loss and prevents cross-contamination without using any filters. The invention described here allows the use of disposable two-dimensional bioreactors for the cultivation of bacterial and other organisms and cells require high aeration.
