Silicone oil reduced syringes

Siliconization is critical to ensure reliable function of prefillable syringes. It ensures optimal syringe performance for delivering medications. Thanks to the hydrophobicity of the silicon layer, potential interaction between the glass and the drug formula is reduced. As a standard, our prefillable glass syringes are spray-siliconized using diving nozzle technology in order to ensure an even coating with the smallest possible amount of silicone oil. We also offer our Gx^® Baked-on RTF^® glass syringes, which are patented in Europe and the USA for the packaging of sensitive biotechnological medications that may interact with free silicone oil droplets. In this procedure, a silicone oil emulsion is applied to the inner surface of the syringe body and subsequently thermically fixated on the surface by heating. This significantly reduces the number of free silicone oil droplets. Despite the considerably reduced amount of silicone oil, the prefillable syringes offer reliable hydrophobic properties and especially low break loose and gliding forces that remain stable throughout the storage period.

Advantages of the Gx Baked-on RTF® syringes

Masking and inactivation of the glass surface, thereby reducing the risk of interaction between the drug formulation and silicone oil
Drastically reduced amount of subvisible silicone oil particles
Long-term stable, evenly distributed, and chemically inert lubricity coating
Very even break loose and gliding force profile
Ensures optimal functionality and drug formula stability over the period of medication storage
Patented in Europe and USA
