Concentrators for Ultrafiltration
Centrifuge tube microfiltration devices for sample concentration and buffer exchange of dilute protein samples by centrifugal ultrafiltration through filter membranes; 9K, 20K and 150K MW cutoff varieties available in 7mL and 20mL capacity units.
Developed and manufactured from scratch, these devices are quite simply the most efficient and versatile centrifugal concentrators you're likely to find anywhere. We designed and optimized them for use with protein samples, but they also provide exceptional performance for nucleic acid samples.
