Protect your product at the final step

Fill-Finish Solutions for Bioprocessing

Fill-finish is where months of manufacturing come down to one moment. A single contamination event or loss of control can cost you an entire batch. ProConnex® single-use solutions give you closed, configurable fluid paths from formulation through final fill. They help you protect product quality, keep your process moving and scale with confidence.

What is fill-finish?

Fill-finish is the final step in biomanufacturing. The purified drug product is sterile-filtered, filled aseptically into vials, syringes or cartridges, and then sealed for distribution. It is the last chance to protect everything your upstream and downstream teams have built. Sterility, accuracy and product integrity can't be compromised here.

The fill-finish challenge

Today's biologics and advanced therapies are more sensitive, more valuable and more complex than ever. Fill-finish teams have to:

Maintain sterility through every transfer and connection

Protect fragile molecules from shear stress and product loss

Deliver batch-to-batch consistency across campaigns and sites

Scale from clinical to commercial without redesigning the process

Meet rising regulatory expectations for process control and contamination prevention

Switch products quickly in multiproduct and CDMO environments

Single-use Fill-Finish Solutions for Biologics Manufacturing

Protect sterility and confirm formulation accuracy with ProConnex® flow paths and PATsmart™ in-line analytics 

Closed, configurable fluid paths 

ProConnex® single-use solutions for fill-finish 

ProConnex single-use assemblies connect each fill-finish step with flow paths designed for the specific application. They are pre-sterilized, built to your process and supplied with the documentation that regulated manufacturing requires. 

  • Custom assemblies: Bags, tubing, connectors, filters and manifolds designed for your formulation, transfer and filling steps. 
  • Closed processing: Sterile connections reduce open manipulations and support your contamination control strategy. 
  • Product protection: Validated films and components help maintain product quality during hold and transfer. 
  • Reliable supply: Standard and custom designs are supported by a global manufacturing network.

Measure what matters before it's in the vial

PATsmart™ analytics: real-time insight at the final step 

PATsmart process analytical technology adds inline monitoring to fill-finish, so teams can confirm product quality as the process runs instead of waiting for offline results

  • Inline concentration monitoring: Verify the formulation target in real time before filling begins. 
  • Faster decisions: Cut sampling and lab hold times between formulation and fill. 
  • Less risk: Find deviations early, before high-value product is committed to containers. 
  • Data integrity: Digital process records support batch release and continuous improvement.

Frequently Asked Questions

It's the final manufacturing step. The drug product is sterile-filtered, filled aseptically into its final containers and sealed for distribution.

Single-use fluid paths remove the need for cleaning validation, reduce the risk of cross-contamination and support flexible, multiproduct manufacturing.
