I use it for it's intended purpose and to blow dust away from optics and other laser parts.

XTEND-IT® is a compressed dry nitrogen gas blanket designed to extend the shelf life of moisture sensitive polyurethane products by displacing the air in the container it is sprayed into.

So it is basically a barrier to air (oxygen)..

Moisture, H2O.

This product is only a recommendation.
Camera pumps do work, but the advantages to dry gas is it's dry and under high pressure high enough to really remove dust particles throughly. What happens when removing dust with a ambient air is it contains moisture. This moisture clings to the dust particles which makes dust particles more likely to stick to surfaces even after repeated use. The high pressure gas in this can is delivered via a thin straw making for precise removal.

Sorry (not sorry), but this is stupid.

I don't know where you read that this is nitrogen (I think you made it up, but that remains to be seen)... but the MSDS on their own goddamn site says it is a fluorocarbon (1,1,1,2 Tetrafluoroethane specifically)

The difference is this can of fluorocarbon is $21.59 plus shipping, While standard air duster is $3/can with free shipping

If that isn't stupid enough for you, The fluorocarbons used in regular canned air (which is not air, by the way) are also inert and moisture free. and 1,1,1,2 Tetrafluoroethane is listed right on the wiki page as a common canned "air" substance ANYWAY. You've fallen for the marketing wank.



tl;dr: Steve wants us to pay seven times the market price for air duster.
 
Fluorocarbons or chlorofluorocarbons are commonly known as freon. Now, this is not the same as tetrafuoroethane, but they carry the same restrictions that the freons do. Hence, the added expense.
 
Cyp is right, it's just fancy compressed air. I honestly wouldn't trust a layer of gas to protect stuff that's sensitive to the environment anyway, I always store my delicate and reactive components/substances with a desiccant and an oxygen scavenger.

My mistake.I used dry nitrogen at work for urethane and assumed this was canned nitrogen.

I couldn't care less if you don't buy it. It was just a recommendation. Thanks for setting t hings straight.

I'm often surprised but should not be how often people choose to be jerks instead of choosing civility. Aren't you cyparagon? If your present employment does not work or you want a new profession I would suggest you join the US diplomatic corps. You have a way with words.
