Seamless, deep-drawn stainless steel interior improves resistance to contamination and features easy-to-clean cove corners. Triple-wall construction incorporates fiberglass insulation and enhances temperature uniformity and control. Walls and plenum components are formed from high-quality corrosion-resistant stainless steel. Reinforced construction permits stacking. The exterior features a scratch-resistant paint finish. The rear wall of the unit has a 3.8cm (11/2") porthole with a silicone stopper. The water jacket drains into an included autoclavable water pan. Adjustable leveling feet are standard. The two-part door has a tempered glass inner door that is heated by the outer door to prevent condensation. Door features a test port in the center for in-operation readings. A closed-cell silicone inner door gasket maintains positive seal. Incubators feature the advanced IntrLogic II control, alarm, and monitoring system for safe, efficient operation. The control panel features only three buttons for simplified operation. Key-operated setpoint security system prevents unauthorized control access. Easy-to-read, vacuum fluorescent display. An RS-485 data port and IncuSoft data logging software are standard. Incubators will automatically switch to the backup tank when main CO2 tank is empty. Audible/visible CO2 alarm is programmable to within 1% deviation above or below the setpoint. Additional alarms indicate high water-jacket temperature and high/low deviation from chamber temperature setpoint. Incubators feature remote alarm contacts and a battery backup for the alarm control system. An in-chamber HEPA filter dramatically improves air quality and provides additional protection from contamination. Automatic CO2 control is provided by either a thermal conductivity (TC) sensor or an infrared (IR) sensor. The TC sensor provides accurate CO2 control for applications with more consistent temperature and humidity levels. The IR sensor is ideal for precise CO2 control in
