This is a question we get asked often. It depends on a number of variables, including: cryogen settings, condition of handpiece and frequency of use. If you feel you are changing cryogen canisters more often than usual, it may be time for a handpiece service as there may be a leak in the system.

While it is best to check with your particular city prior to disposal, completely empty canisters are safe to throw away in the regular garbage. For optimal results, Laser Scientific recommends always purchasing new Cryogen canisters and never refilling or purchasing refilled canisters. Refilled canisters can result in overtreatment and Cryogen burns due to rust and particles buildup inside the canister.

Refilling Cryogen has the potential of contaminating the hand piece‘s DCD valve and the flow line with particles of rust and other debris. In time, this debris will can obstruct the flow line causing leakage and damage to the valve.
