Yes, extending the spin times is sufficient. However, the time range would have to be experimentally determined by the user.

General description
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.
Application
- Ultrafiltration with 10,000 Dalton molecular weight cutoff Ultracel® membrane.
- Concentration of biological samples containing antigens, antibodies, enzymes, nucleic acids, or microorganisms.
- Purification of macromolecular components found in tissue culture extracts or cell lysates and protein removal prior to HPLC.
- Concentration of dilute or pre-purified proteins from column eluents.
- Desalting, buffer exchange and protein dialysis.
- Size exclusion and protein fractionation.
Features and Benefits
- Ultracel® regenerated cellulose membrane with 10 kDa NMWCO delivers retentate recovery of greater than 90%.
- Vertical membrane reduces concentration polarization for ultra-fast spin times (as fast as 5 minutes).
- Heat-sealed membrane minimizes downstream extractables.
- 100% integrity tested for reliable performance.
- Convenient sample monitoring with translucent housing and volume gradations.
- Direct pipette sample access eliminates processing step to recover concentrate.
- High concentration factors of 80–100X.

If my centrifuge only goes to 3,052 g, is it okay to centrifuge for a longer period of time to get the same separation? It is a swing-bucket centrifuge using the 10 MWCO filters.

How should the tubes be sterilized without damaging the membrane?
1 answer-
There are no validated sterilization methods for the Amicon Ultra devices. However, these devices can be "sanitized" with a spin cycle with 70% ethanol, followed by 2 rinsing spins with sterile water. It is recommended to filter the concentrated sample using a sterile 0.2 µm syringe filter (e.g., SLGVR33RS) after processing on the Amicons.

What speed can this product be centrifuged at ?
1 answer-
For this item when using a swinging-bucket rotor, spin the device at 4,000 × g maximum for approximately 10-40 minutes. When using a fixed-angle rotor, orient the device with the membrane panel facing up. For Amicon® Ultra 3K, 10K, 30K, and 50K devices, spin at 7,500 × g maximum for approximately 10-40 minutes. For Amicon® Ultra 100K devices, spin at 5,000 × g maximum for approximately 10-20 minutes.
