Two versions of these incubators with electronically controlled APT.line™ preheating chamber are available depending on the application: The BD series with natural convection for all standard applications and the BF series with forced convection for applications with high load density.

• Additional safety is provided with disinfection at 100 °C and easy operation
• DS controller with integrated timer 0 to 99 hours (BD series), MS controller with several timer functions such as 'Delayed OFF' and 'Delayed ON' (BF series)
• High degree of temperature accuracy and fast temperature recovery time after the door has been opened (BF series)
• Adjustable fan speed (BF series)

The advantage of the BF series with forced convection is extremely precise temperature distribution within the incubator, even with high load density, and fast temperature recovery times after the door has been opened. APT.line™ incubators provide superior temperature accuracy and meet all quality requirements for uniform, reproducible incubation conditions. Their broad temperature range and high performance mean that the BD and BF series can be used for all incubation tasks in research, production and quality assurance. Units up to 115 litres can be stacked on top of each other to save space. The incubators are easy to clean with residue-free cleaning of entire inner chamber and inner glass door.

All models have an independent adjustable temperature safety device Class 3.1 with a visual alarm, which saves the samples and the incubator, and adjustable ventilation by means of rear exhaust duct, Ø 50 mm with ventilation flap and front ventilation slide. Both BD and BF series have RS422 interface for communication software (software optional). On the BF series the interface is switchable to printer output with accessory RS232/RS422 interface converter.
