Laboratory incubator KB 720

for bacteria culturesnatural convectionrefrigerated

Product description
The KB 720 cooling incubator is a laboratory-grade unit for controlled incubation of microorganisms. It maintains precise temperature conditions across the chamber even under full load, offers a programmable hot-air disinfection routine and a second setpoint for weekend operation. The current KB model reduces energy consumption by up to 40% compared with the prior model.
