This is a big machine with a 45 cm (approximately 18-inches) and 22-liter volume sterilization chamber. The vacuum pump it comes with features a water-cooling system. This kind of technology makes the Vacuklav 44 B+ an ideal autoclave for practices and hospitals that wish to sterilize a high number of instruments in a short amount of time. Up to 7 kg (15 lbs) of wrapped instruments can be sterilized in the Class B program in about 30 minutes, which includes the fractional pre-vacuum and drying. The Quick-Program S allows for unpacked instruments to dry in just 10 minutes. The color touch display is designed to prevent user error. All the menus are intuitive and easy to use. The software is already integrated into the device, and is designed to help with the identification of sterilized instruments.
