Amicon^® Ultra 15 mL centrifugal devices with Ultracel^® 100,000 Dalton molecular weight cutoff filters provide fast ultrafiltration, and reliable retention of macromolecules. For example, IgG (156 kDa) at 1 mg/ml initial concentration is retained at >90% .

The vertical design and available membrane surface area provide fast sample processing, high sample recovery (typically greater than 90% of dilute starting solution), and the capability for 80-fold concentration. Solute polarization and subsequent fouling of the membrane are minimized by the vertical design, and a physical deadstop in the filter device prevents spinning to dryness and potential sample loss.

The concentrate is collected from the filter device sample reservoir using a pipetter, while the ultrafiltrate is collected in the provided centrifuge tube. The device can be spun in a swinging bucket or fixed angle rotor. With their vertical membrane design and deadstop, Amicon^® Ultra 15 mL filters deliver the highest recovery with short spin times.

We are committed to bringing you Greener Alternative Products, which have been re-engineered to enable more sustainable research solutions. The inner filtration device is made from 60% bio-circular material allocated using the ISCC mass balance approach.
