A detailed look at each Tangential Flow Filtration market segment reveals that ultrafiltration remains the dominant technique. It is the gold standard for protein concentration and diafiltration, providing the exact molecular weight cut-off needed to separate target molecules from smaller impurities. However, microfiltration is gaining ground, particularly for cell harvesting and clarification stages where high solids loading is a challenge.

The market is also segmented by product type into systems, membrane filters, and accessories. While the systems themselves represent a significant capital investment, the recurring revenue from membrane cassettes and cartridges provides a steady income stream for suppliers. This "razor and blade" business model ensures that innovation in membrane materials remains a top priority for the industry's leading players.

FAQ:

• Q: What is the difference between microfiltration and ultrafiltration in TFF?

• A: Microfiltration uses larger pore sizes for cell removal, while ultrafiltration uses smaller pores for concentrating proteins and removing salts.
