That's the beauty of argon; it really does flush the air out of the containment.

Are there any other advantages? To use a gas flush , you will need to invest in a cannister of nitrogen, or a cannister of argon (usually more expensive than nitrogen), or a nitrogen generator (about $4000, I think). For compressed gas you will also likely pay an annual cannister rental fee, and have to buy your own two stage regulator and hoses. To be effective, you should also have an oxygen analyzer ($1300+) to ensure that you have completely purged the container and that it stays below 0.1% O2. I don't think a single flush will remove all the oxygen, so you will likely need to supply a constant stream of gas into the container. If so, you will need a humidity sensor and a means to humidify the argon or nitrogen as you pass it into the bag. All in all, if you don't already have a set up, my advice is still to use a passive rather than an active system when anoxia is not done on a regular basis. js Jerry Shiner Keepsafe Microclimate Systems Specialists in the design, procurement, and installation of environmental control systems for museums and archives www.keepsafe.ca i...@keepsafe.ca +1 416 703 4696 +1 800 683 4696 The only problem with argon is that you have to have the gas -----Original Message----- From: "Louis Sorkin" <sor...@amnh.org> Sent: 4/1/2009 1:36 PM To: "pestlist@museumpests.net" <pestlist@museumpests.net> Subject: RE: [pestlist] freezing Japanese laquer This is a message from the Pest Management Database List.
