Kronos TFF system as a tool for process development as part of QbD


Tangental Flow Filtration (TFF) aka Cross Flow Filtration, is a critical step in downstream bioprocessing and has its unique set of challenges.

Using the TFF technique has major advantages: unlike a dead-end impact filter, the product stream in TFF moves in parallel to the filter. This allows solids to be kept in solution and minimizes the buildup of a “filter cake” which can foul the membrane.

However, downstream processing departments struggle on topics like:
“How can I do TFF process development meeting QBD requirements?“
“How can TFF be more reliable and better optimized for process-driven systems?”

Fortunately, today’s industrial design — even in compact, benchtop TFF systems — provides for accurate and continuous transitions to scaling up.


What did we learn?

Use of an automated and flexible tangential flow filtration system as a tool for process development.

During the lecture we will describe typical process development methods, also taking into consideration cleaning, product yield and economical aspects. A case study “Recovery and Concentration of Cell Culture-Derived rVSV-Spike Vaccine Candidate for Covid-19” will serve as an example.
