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

General description
Amicon® Ultra 4 mL centrifugal devices with Ultracel® 10,000 Dalton molecular weight cutoff filters provide fast ultrafiltration, and reliable retention of macromolecules. For example, Cytochrome C (12.4 kDa) at 0.25 mg/ml initial concentration is retained at >95% .
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.
