Are RSA-Pro X Vials & Inserts the Same as Silanized Vials & Inserts? – FAQ

No, they are very different! Silanized vials coat glass using gaseous silanes under pressure. While Silanizing does convert hydrophilic glass into glass with a hydrophobic coating, RSA-Pro X™ Glass uses a very different surface treatment. The biggest difference as far as you are concerned is that Silanized Glass Vials are susceptible to degradation in the […]

What is Protein Oxidation? – FAQ

It is reported in the literature that Proteins can degrade when they react with Oxygen. This can occur when Proteins are stored in plastic containers and Oxygen permeates the walls of the Vials. Also, during gamma irradiation sterilization, free radicals can be generated in plastic containers that can cause degradation of the Proteins. RSA™ and […]

Why is Borosilicate Glass Reactive and Adsorptive? – FAQ

It is widely known that Borosilicate Glass is often covered with dissociable silanol groups, (about 6 groups / Square Nano-Meter) giving it a negative charge when in contact with solutions, especially water based diluents. Positively charged compounds (bases) will be adsorbed to these negative sites. Adsorption can be due to these silanols but there are […]
