Celltreat® Centrifugal Filters

Celltreat® Centrifugal Filters are engineered for fast, efficient, and reliable sample processing in laboratory workflows. Featuring PES membranes with multiple molecular weight cut-off (MWCO) options, these filters are ideal for applications such as sample concentration, purification, and buffer exchange.

The innovative dual vertical membrane design maximizes active surface area, enabling high-performance filtration with excellent sample recovery.

Applications include sample concentration, molecule purification, protein fractionation, buffer exchange, and desalting.
