Latest Patents
One of Glenn D. Selfridge's latest patents is a controlled atmosphere enclosure designed for laboratory use. This innovative incubator features a housing that defines a thermally insulated inner chamber with a controlled gas atmosphere. The design includes devices for sensing the characteristics of the incubator chamber atmosphere and for conditioning it, all positioned in a gas recirculation path outside the chamber. The gas atmosphere circulates from a chamber outlet in the upper portion of the chamber, through the recirculation path, and returns to the chamber through a chamber inlet in the lower portion. The recirculation path includes a blower, a filter, a CO₂ sensor, and a humidifier. A microprocessor-based controller responds to the CO₂ sensor's output to maintain a selected CO₂ level in the chamber atmosphere. The incubator also features upper and lower diffuser plates that create an upward vertical laminar flow of gas through the chamber, ensuring optimal conditions for laboratory experiments.
