The Julabo DYNEO DD-449F refrigerated and heating circulator is ideal for basic research, materials testing, technical systems and more. This model is suitable for internal and external applications with easy switch over between the two.
The DYNEO series offer high heating/cooling capacities for short heat-up and cool-down times. The DD-449F is designed to be energy efficient and uses environmentally friendly natural refrigerant.
Its space-saving cooling coil design delivers more usable space in the bath tank. The DD-449F’s large bath volume makes the unit ideal for precisely tempering larger or a variety of different samples in the bath.
