MDS Medical have a great selection of autoclaves for Dental, Veterinary, Podiatry, Chiropody, Cosmetic, Tattoo and Body piercing. The easiest way to find out what is right for you is to ask how often you need to run the unit and how heavy the total load will be. For example if you have 1-2kg of instruments going though on 1 cycle and need to do that 2-3 times a day a 12L autoclave would be best suited.
Also keep in mind if you need to log the cycles completed you will need a USB data logger or printer.
Engineer tip: If you have high frequency of use with heavy instrument loads bigger will always be better.
