Yes, it is different from ordinary Deactivation/Silanization. When manufacturers “silanize” ordinary glass Vials they apply Silanes that are Hydrophobic. The RSA-Pro™ Treatment bonds a proprietary Hydrocarbon which has Methyl Groups on RSA Glass Surface to make it Hydrophobic.
Regular Glass Vials can be covered with Hydroxyl Groups/Silanols and harder to completely cover (silanize) as they are contaminated with Grease or Borax Glass Dust to release them from the Tooling Process. The coating can become heavy and fall off (delaminate) leaving a large portion of the vial “un-Silanized” or “un-Deactivated” and Reactive. This defeats the purpose of the treatment and therefore is one reason that only RSA glass is used to make RSA-Pro.
Most importantly, the difference between ordinary Silanized Vials and RSA-Pro Surface Treated Vials are the substrates used in the Deactivation. RSA glass offers virtually no Hydroxyl Groups/Silanols on the Glass Surface to cover during “methylation” as they are precision manufactured. The RSA surface is highly controlled during the manufacturing process to be as pristine as possible; it’s this surface that the RSA-Pro treatment is processed on.
It’s a combination of the surface and the surface treatments (RSA surface purity and reactivity and subsequent surface treatment) that makes the RSA-Pro product superior to “Similar Use” Products on the market.
