Tangential Flow Filtration Devices

Our tangential flow filtration (TFF) products provide versatile solutions for both single-use and multi-use pharma and biopharma applications. Designed to streamline processes, these devices maximize yield and product recovery, enhancing efficiency while minimizing operational complexity. Our Pellicon® Capsules and cassettes can be used for different applications and offer options for every ultrafiltration and diafiltration challenge.

Single-pass TFF with Pellicon® capsules and cassettes

Single-pass TFF with our Pellicon® capsules and cassettes streamlines processing by concentrating process streams without the recirculation of traditional TFF. This is a simple way to increase capacity, concentration, and product recovery while improving footprint. This versatile application also enables continuous and intensified processing, in which in-line volume reduction is coupled to other process steps.

Pellicon® Capsules

Pellicon® Capsules with Ultracel® membrane combine streamlined ultrafiltration and diafiltration with ease of use and process flexibility. This innovative single-use TFF capsule delivers superior mass transfer, flux and optimum recovery in a unique plug-and-play, holderless device that comes gamma sterilized and ready to process in minutes.

Pellicon® 3 cassettes

Pellicon® 3 cassettes deliver high protein yield and consistent performance while offering broad chemical compatibility. They are available with Ultracel® and Biomax® membranes for different processing needs, including mAbs, plasma, insulin, peptides, and vaccines. To overcome the filtration challenges of high viscosity, our Pellicon® 3 cassettes with D screen are easy to use, enable faster processing and are optimized to achieve higher protein concentrations.

Pellicon® 2 cassettes

Pellicon® 2 cassettes are ideal for the ultrafiltration and diafiltration of biologics including concentration, desalting, and buffer exchange of polysaccharides, virus suspensions, and protein solutions. Our Ultracel® and Biomax® membranes offer efficient ultrafiltration while Durapore® membrane is best suited for microfiltration.

Pellicon® XL 50 cassettes

Pellicon® XL 50 cassettes couple our ultrafiltration and microfiltration membranes with linear scalability for process development or small-volume processing.

Prostak™ microfiltration modules

Prostak™ microfiltration modules provide robust construction, reliable performance, and steam-in-place capability, making them suitable for clarification, cell harvest, and multi-use perfusion. The low hold-up volume and open channel design allow high product recovery and gentle flow path for processing shear-sensitive materials.

Support for qualification, risk assessment, and process optimization

Complementing our product portfolio, the Emprove® Program provides three types of dossiers to support different stages of development and manufacturing operations such as qualification, risk assessment, and process optimization. The dossiers consolidate comprehensive product-specific testing data, quality statements, and regulatory information in a readily available format to simplify your compliance needs.
