When working on benign skin lesions, it is a necessity to use the CryoProbe I M to handle different items in the cryosurgical process. This is made with a switch to set up the nitrogen flow to keep gas from being used too much. This uses a cartridge holder with 8 gr nitrous oxide cartridges plus two micro-applicator tips to keep it functional. This is also made with an aluminum housing body to make it safe and strong while being very easy to hold onto.
