The manufacterer of our machine recommends 99.999%. At their presentation before we purchased the machine they showed an example of using different purity levels. When they whiched the supply to 99.99 and then to 99.95 you can visibly see the diffe

| We have a Vitronics SMR400N oven and many times need to use N2 inerting. My problem is that it takes close to an hour of operation to purge the system to achieve the desired O2 levels (~40PPM). This is not only time consuming but results in an inor
