Queue Stabiltherm Lab Oven Cabinet Model SNW300TABB Comes with User Manual and 60 days warranty. Thermo Scientific Incubator co2 300 micro These incubators are designed to create a stable, reliable environment for cell culture applications. They operate at temperatures ranging from 5°C above ambient temperature to +60°C, accurate to ±0.2°C. The gas system controls within ±0.1% of measurable setpoint. • Thermal conductivity Sensor. Provides stable, automatic injection of CO2 • Optional Tank Interchange System: – Allows the interconnection of multiple gas supply cylinders for extended operation. – Control panel warning system signals when one of the gas supply cylinders is empty. – Automatically switches from the empty cylinder to the full cylinder. • Convenience Outlet. A receptacle rated at 115 VAC, 75 watts maximum, is located at the rear of the incubator. The outlet is ideal for electronic recorders or other small loads. Do not exceed the electrical capacity of this outlet. • Automatic Gas Shutoff. Incubator controls shut off the gas supply when the inner glass door is opened to prevent wasting the control gas. • Alarms: – High and low level CO2 setpoint alarms, fixed at ±1%. – High and low temperature alarms. The high alarm can be set by the user. • Chamber Drain. Seamless tank models are provided with a chamber drain fitting at the bottom left side of the cabinet. • Humidity Diffuser. For models with humidity pans, a pan cover diffuses evaporation, optimizing the humidity level. • Optional HEPA filter. Available for all models, HEPA filters remove airborne particulates from the chamber. 1.2 Requirements • A high quality two-stage, low pressure 15 psig (1.056 kg/cm2 ) pressure regulator is required for proper operation of the CO2 gas supply. • In-line gas supply filters must be used on the CO2 supply to prevent damage to the solenoid valve(s): – Type: Microbiological – Specification: 0.3 micron – Location: rear of unit • CO2 used in the incubator must be at least 99.9% pure. • Each chamber contains approximately 12 gallons of jacket water when filled (water-jacketed models only). The water takes six to eight hours to heat from 20° to 37°C. This time must be allowed for the interior temperature to stabilize before any adjustments or permanent calibrations are made. 1.3 Specifications Gas Control Type Thermal Conductivity.
