uPULSE - TFF System
Solution Spotlight

Nicholas McKnight, Product Manager at Formulatrix

Abstract

This talk is from the Protein Crystallization Automation Webinar Series. In the webinar, scientists from all over the world shared how our automation and software solutions have enhanced their protein crystallization workflow. Cole McKnight, the product manager of µPULSE at Formulatrix, presented the solution spotlight for µPULSE.

 

Unlike centrifugal units with traditional dead-end filtration, the µPULSE uses miniaturized TFF to prevent a concentration gradient from forming at the membrane surface. This increases sample recovery and prevents slow concentrations associated with membrane fouling.

 

With TFF, the concentration process is continuous and gradual allowing for samples to be concentrated up to 2.5x faster than using dead-end filtration. The system also enables the automation of buffer exchange protocols while maintaining the lowest TFF hold-up volume in the industry, just 650mL.
