Rubber coated closures

Omniflex is an inert, flexible, fluorinated polymer coating for pharmaceutical rubber closures which covers the entire product surface, including the trim edge. Whether it is Omniflex, OmniflexPlus or OCP (Omniflex Coated Plungers), the chemical inertness of the fluorinated polymer coating provides a very high degree of compatibility with pharmaceutical or biotechnology products.

With the latest innovation, Omniflex3G, Helvoet Pharma has fused its Omniflex fluorinated polymer coating together with its ultra-clean FM457 compound to form the latest major advancement in rubber closure technology.

The revolutionary new Omniflex3G closure possesses exceptional properties including a rubber substrate with exceptional purity, a superior fluoropolymer barrier that covers the stopper completely, silicone-free machineability, and the highest level of seal integrity that is maintained even after exposure to ultra-low, cold storage temperatures of -78°C / -108.4°F.

The absence of additional siliconisation makes the Omniflex range the key component for biotech applications, Cephalosporines, Cytostatics, oil solutions and high-end pharmaceutical product developments. Our coated closures range includes serum and lyophilisation 13mm, 20mm and 32mm stoppers as well as a full range of prefilled syringe components.

RfS and RfU components

Helvoet Pharma supplies to its customers products in RfS or RfU. In both cases the products are washed with purified water and rinsed with water for injection. When using RfS components, a very high standard of particulate and biological cleanliness is applied. The products are packed in special autoclavable bags (Tyvek).

There is no need to wash and repack goods before the sterilisation process in the autoclave or use our RfU components, where components are supplied gammairradiated. Components can be used immediately in the clean room without pre-treatment. Both RfS and RfU product treatments are based upon validated processes
