What Standard of Resonator Gas delivery system

What Standard of Resonator Gas delivery system

What Standard of Resonator Gas delivery system

(OP)
What Standard of Resonator Gas delivery system is best practice for a Co2 laser to minimise damage to laser when changing bottles etc, Do we need dual bottles with a changeover & purge system or is a single bottle system
acceptable. Are Relief valves with neoprene seats ok ?
( I have read that neoprene contaminates the laser gases)
 
Is Anyone using concoa regulators ?

we are looking at  model 601 for laser gases
                   model 623 for laser gases

thanks steve

RE: What Standard of Resonator Gas delivery system

Steve,

I just found this site, and saw your post. I noticed it was from quite a while ago.

I use Concoa regulators, and have had no problems. In fact, the laser techs tell me they are surprised as to how low my coefficient stays over a long period of time.

I do have a rather unorthodox trick, or habit, when changing the laser gas only.
I crack the existing cylinder slightly while removing the gauge. I then quickly connect it to the new cylinder, which is also cracked slightly.

I also roll the new bottle around just in case it has been standing for a long period of time. And I crack the new valve hard before connecting to remove any debris.

I chose to use a Teflon line for this gas.

Frank
