RayDyLyo® – A New Standard in Vial Capping

A revolutionary, tool-free capping system for aseptic environments.

Revolutionising the Vial Capping Process

RayDyLyo® is an innovative alternative to traditional crimp capping which simplifies the capping process while offering sterility, safety, and efficiency. Designed to work seamlessly with 13mm and 20mm crimp neck vials, RayDyLyo® eliminates the need for crimping tools and ensures a fully aseptic process. This single-step closure system is available in sterile Ready-to-Use (RTU) or Ready-to-Sterilise (RTS) formats, making it suitable for manual, semi-automated, and fully automated capping operations.

RayDyLyo® enhances production flexibility and quality, reducing the risk of contamination and cosmetic defects. It’s compatible with existing filling and capping lines, offering a cost-effective solution for pharmaceutical and biotech companies. The innovative tamper-evident design and colour customisation options provide additional security and branding benefits. Whether used for small batch clinical trials or large-scale production, RayDyLyo® is a revolutionary new step in healthcare packaging.

Key Benefits:

  • Tool-free, one-step closure process – simplifies aseptic capping
  • Eliminates crimping – reducing cosmetic defects and contamination risks
  • Flexible & scalable – suitable for clinical trials, research, and industrial production

Who Can Use RayDyLyo®?

RayDyLyo® is ideal for pharmaceutical and biotech companies, CDMOs, and research institutions requiring sterile, reliable, and efficient vial capping. Its flexible design makes it perfect for applications ranging from small-batch clinical trials to fully automated industrial production lines.

Why Use RayDyLyo®?

RayDyLyo® streamlines vial capping by integrating into aseptic filling lines, ensuring sterility and reducing production risks. Additionally, the nested aseptic capping system enables gloveless operation in isolators, minimising human intervention and contamination.

The RayDyLyo® vial closure system simplifies the filling and capping of vials, thereby reducing time to market and saving you time and resources. Pre-fitted with your choice of Injection or Freeze Dry (Lyo) Stopper, vial closure becomes a one-step process.

With its push-fit design, manual closure of an ISO Standard Vial can be achieved with a simple downward pressure, eliminating the need for specialist crimping tools. This makes it the ideal solution for small scale research & development projects, as well as clinical trials; and when the time comes to scale-up RayDyLyo supports inline filling and capping on existing production lines. RayDyLyo® caps can be supplied Gamma Sterilised and Ready to Use (RTU), or clean and Ready to Sterilise (RTS) via Gamma or Steam Sterilisation methods.
