Laboratory incubator KB 470

for bacteria culturesnatural convectioncooling

Product description
The KB 470 cooling incubator is designed for microbiology applications and delivers precise temperature control for cultivation of microorganisms even under full load. It includes a hot-air disinfection routine, programmable secondary setpoint (e.g. weekend operation), stainless-steel interior and modern inverter cooling for reduced energy consumption (up to 40% less than the previous model).

Benefits

• Precise: stable incubation conditions with power reserves for uniform results
• Reliable: long-term failsafe operation using proven compressor technology and stainless-steel interior
• Functional: integrated hot-air disinfection and simple programming of a second temperature setpoint
• Efficient: modern inverter cooling reduces energy use up to 40% vs previous model
