got my new autoclave in its a kavoclave its alot like a prestige autoclave all automatic steam pressure autoclave. i ran some stuff through it when it came in to make sure it functions properly when it was done i noticed there was moisture all inside of the autoclave bags on the tubes and tips. is this normal for moisture to get inside the clave bags. also after i let them sit out and cool for a while the moisture went away.

After you pull your tubes from their soak (cidex or similar) and rinse, lay them out on paper towels and dry before bagging. If they are damp, the moisture is normal. steam/presure = moisture. Also does your autoclave have a drying cycle? Are you venting, or cooling without venting?

no it doesnt have a drying cycle and the tubes were dry. the clave does have a manual vent on it to bleed off pressure after cycle is completed if you need your things quickly. but as it cools the pressure goes down for normal use it has a thing that shows there is no pressure left and its safe to open a red button that pops up on top of the machine when it pressurizes.

You've gotta remember that theres a hell of alot of pressure built up in there. Thats because of one thing only, heat. When the heat is removed the air decompresses and cools and miosture forms. The pressure release valve only works beyond a certain amount of lbs of pressure. The rest of the compressed air left in the pot after the hot cycle is accounted for per volume of the container and is decompressed during the cool-down, allowing you to be able to open the lid. If the valve only opens beyond a certain level, then when it's closed, the remaining air and eventual moisture buildup has nowhere to go until you open it back up. Just let it evaporate on it's own after opening.

If it has no vent to manually or otherwise open during cool-down, then I see no other way around the issue.

i discovered somthing recently that had somthing to do with this post so i thought i would post it. i have noticed that the large bags i use that are made by tri county dental supply get the moisture, and the defend bags i recently bought do not get any moisture in them.

Crosstex and Defend are the same bag - different price tag. Same concept, ultrasonic, bag it, seal it, autoclave it. Let it dry.
