EZBio® Viper Filling Needles: Precision Engineering for Aseptic Fill-Finish Operations
In aseptic fill-finish operations, precision and consistency determine product quality, yield, and safety. Every droplet matter, and every transfer must be controlled, traceable, and contamination-free.
To meet the growing need for accuracy and sterility in pharmaceutical and bioprocessing environments, Foxx Life Sciences introduces the EZBio® Viper Filling Needles engineered for unmatched reliability, precision, and compatibility across leading filling systems.
These high-performance filling needles have been developed to address one of the most critical steps in drug manufacturing and formulation: the final fill. Designed and manufactured to deliver consistent liquid dosing, they combine durable materials, precise geometry, and excellent chemical compatibility to support both R&D and large-scale production environments.
The EZBio® Viper Filling Needle is a precision-engineered dispensing component designed for use in bioprocess and pharmaceutical fill-finish operations. Each needle is constructed using a 316L stainless steel cannula securely bonded to a USP Class VI polycarbonate hub, creating a robust and biocompatible assembly ideal for aseptic processing.
The cannula undergoes electropolishing and passivation, producing a smooth, corrosion-resistant internal surface that enhances fluid flow and prevents particle retention. This ensures not only accuracy in dosing but also superior cleanliness and durability during repeated use in controlled environments.
EZBio® Viper Filling Needles are fully compatible with leading filling machines, including those from Pall, and are available in a wide range of inner diameters (0.8 mm to 4.8 mm). Custom lengths, IDs, and hub configurations can be tailored to specific equipment or process requirements.
