2.0 Performance Parameters and Features
• Each chamber's water-jacket holds 18 to 20 gallons (up to 75.7 liters) of water that, in conjunction with the
microcomputer control system, provides an interior chamber temperature uniformity of
±
0.2
°
C at 37.0
°
C.
•
The microcomputer temperature control system has two temperature sensors located inside the chamber at the back
wall. The temperature sensors compare the values to a set point and execute a differential control algorithm that
energizes a solid-state switch, supplying power to the heaters.
•
Easily removable inner shelves and rails for sterilization.
•
Up to 16 shelves can be placed inside the chamber (4 shelves are shipped).
•
Space-age high temperature material is used to insulate the Water Jacket walls.
•
Most electronics, motors, pumps, and valves are fully accessible from the back of the unit.
•
A CO
2
sample port is provided on the front panel just below the door to check the concentration of CO
2
in the chamber.
•
The CO
2
percentage is controlled by a solid-state gas infrared sensor using a single light source with dual wave length
detection, providing accurate monitoring of CO
2
.
•
After a door opening the CO
2
level automatically recovers to 5.0 + 0.2/- 0.5% within a 5 minute period on average.
•
The outer door includes an internal radiant heater in order to minimize condensation on the inner glass door.
A magnetic outer door gasket helps to insure a tight seal against the cabinet.
•
The inner glass door is 3/16” tempered with smooth-ground edges and seals are tight against a silicone rubber gasket.
The door latch is cam action.
A momentary switch monitors the door position, the position being opened or closed.
•
All control electronics are protected with a circuit breaker that may trip at 110% of loading rating but will trip at 145%
of load rating in less than 2 seconds.
Should the circuit breaker open (pop-out button will appear), merely depress to reset.
•
The Incubator has adjustable leveling legs to compensate for uneven laboratory surfaces.
