Hello, after a while of having bought my CO2 cilinder, it took me a while to find a place to fill it. I´ve found 2 places. In one place they take my cilinder and freeze it, then they fill it with liquid CO2. In the other place they take my cilinder and plug it in to fill it with CO2, but this one is not liquid. I have read that the liquid CO2 last longer than the other one. What can you tell me about it. Thank you.

A cylinder holds liquid co2 under pressure. If they fill it with gas, it will become liquid under pressure. Freezing and filling with liquid co2 allows for less waste, as they wouldn't have to release the pressure as often to complete the fill.
