Repligen MicroKros Hollow Fiber Filter mPES 750 kDa

The Repligen MicroKros Hollow Fiber Filter, featuring an mPES (modified polyethersulfone) membrane with a 750 kDa (kilodalton) molecular weight cutoff, a 0.5 mm fiber diameter, and a 40 cm² filtration area, is a specialized filtration device designed for laboratory-scale ultrafiltration and diafiltration applications.   

This hollow fiber filter is particularly useful in bioprocessing for the concentration and purification of biomolecules. The mPES membrane offers excellent chemical resistance and low protein binding, ensuring minimal sample loss and maintaining the integrity of sensitive biomolecules. The 750 kDa molecular weight cutoff allows for the selective separation of molecules based on size, making it suitable for applications such as protein concentration, virus purification, and buffer exchange.   

The 0.5 mm fiber diameter and 40 cm² filtration area are optimized for small-volume processing, providing efficient and rapid filtration while minimizing sample hold-up volume. The hollow fiber design allows for high surface area-to-volume ratios, enhancing filtration performance and throughput. This Repligen MicroKros Hollow Fiber Filter is a valuable tool for researchers and scientists who require precise and efficient ultrafiltration and diafiltration in their laboratory workflows.
