Multigas incubator CB 260

CO2for cell culturesnatural convection

Product description
The CB 260 CO₂ incubator is designed for cell culture workflows in medical and pharmaceutical laboratories. It supports controlled atmosphere cultivation with precise CO₂ and optional O₂ control, and integrates hot-air sterilization to minimise contamination risk.

Benefits

• Contamination control through 180°C hot-air sterilization concept
• Stable cultivation environment with tight temperature and gas regulation
• User-oriented operation via touchscreen and accessible data export
• Low operational overhead: efficient humidification and no consumable-dependent sterilization

Important characteristics

• Optimized double-pan humidification with condensation protection
• Hot-air sterilizable single-beam IR CO₂ sensor
• Seamless stainless-steel inner chamber with flange shelf support
• Fanless interior design with Venturi CO₂ mixing nozzle
• Intuitive touchscreen controller and internal data recording (USB, open format)
• Visual and acoustic fault alarms; interfaces: Ethernet, USB, potential-free alarm contact
• Fail-safe CO₂ control to protect cell culture pH
