The incubator cabinet is tough and well insulated with an observation window and is fitted with the temperature control system which can be finely adjusted without opening the lid. Inside is the removable, purpose designed reptilian egg chamber which is almost sealed and allows the eggs to be maintained at virtually 100% humidity.

Oxygen supply to the chamber is regulated by a simple vent control. The inner chamber is formed from clear plastic and is easily cleaned. The incubation thermometer (built to Brinsea's specification) fits into the lid of the inner chamber and can be viewed through the cabinet window without disturbing the eggs.

Vermiculite, supplied with the incubator, half fills the inner chamber and is soaked in water. The eggs are then part buried in the vermiculite. Condensation will not form on the inside of the lid of the chamber while the incubator is in use - preventing drips falling on the incubating eggs.
