RTF Vials for Injectables

Applications & Areas of Use

AT-Closed Vials® are ready-to-fill vials for injectable drugs, designed to be used in aseptic fill finish processing of biopharmaceutical drugs.

The vials are particularly suitable for use with sensitive advanced therapeutical products such as cell and gene therapy preparations with special requirements for processing, transport and storage.

The polymer injection bottles also offer advantages in the processing and handling of hazardous substances such as cytotoxic oncological drugs or radiopharmaceuticals.

AT-Closed Vials® are designed to be seamlessly fed into robotic filling lines for automated, aseptic filling.

Product Features Overview

The AT-Closed Vials® are injection-molded from clear-as-glass COC (Cycloolefin-Copolymere). The advantages of plastic injection bottles as glass replacement are particularly significant for biological drugs that require transportation, storage, freezing and thawing.

The break-resistant material can withstand the stresses of cryogenic freezing with no loss of container-closure integrity. The polymer vials have a low leachables profile for biopharmaceuticals, avoiding impurities or adverse reactions that could inhibit the efficacy and safety of the contained active substance. The higher break resistance of plastic compared to glass vials avoids the risk of contamination when handling highly potent or cytotoxic drugs.

Our Expertise

Automated Two-Component Processing for 100% Purity

The particular challenge in the production of closed ready-to-fill vials is to ensure that the process and the end product are absolutely germ-free. We use a technically complex injection molding tool, which allows both components of the end product to be completed in one production cycle. In a fully automated manufacturing process, the vial and stopper are injection molded and immediately robotically assembled, all under ISO 5 cleanroom conditions. This minimizes particle content compared to conventional manufacturing and assembly processes.
