Dry Heat Sterilizers vs Steam Autoclaves

Dry heat sterilization eliminates the need for steam and a vacuum atmosphere found in autoclaves which results in a number of benefits when using this method. Ease of use and cost effectiveness are major advantages of dry heat because the sterilizers require a fraction of labor to install and little to no labor to maintain. Gruenberg dry heat sterilizers also offer increased load capacity and an optimized sterilization cycle so you can achieve a higher output.
