FAQ
| Question | Answer | ||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Amicon Ultra units are offered in what volumes? | Amicon Ultra units are available in 0.5 mL, 4mL & 15ml volumes. | ||||||||||||
| What is the recommended rotor for Amicon Ultra units? | Any rotor capable of accommodating 22.7 cm in diameter and 124 mm length centrifuge tubes for the Amicon Ultra-4 and 35 mm in diameter and 121 mm in length for the Amicon Ultra-15 can be used for Amicon Ultra units. | ||||||||||||
| How should I select the appropriate Molecular Weight Cutoff (MWCO) for Amicon Ultra? | Select a Molecular Weight Cutoff that is 2x smaller that the Molecular Weight (MW) of the solute of interest. | ||||||||||||
| Which membranes are available in Amicon Ultra units? | Amicon Ultra units are only available with Ultracel regenerated cellulose material. This high recovery/low binding membrane is offered in 3,000, 10,000, 30,000, 50,000 & 100,000 MWCO. | ||||||||||||
| Can the Amicon Ultra be spun to dryness? | No, the Amicon Ultra has a built in deadstop. | ||||||||||||
| Can the Amicon Ultra be used with nucleic acids? | Yes, Amicon Ultra units have been evaluated for use with Genomic and PCR fragments. The 30 kDa MWCO provides the best balance between recovery and spin time. Protocols related to Genomic and PCR fragments can be found in the user guide. | ||||||||||||
| What is the maximum sample volume for Amicon Ultra? |
|
||||||||||||
| What is the maximum centrifugal force I can spin Amicon Ultra-4 & Amicon Ultra-15? |
|
||||||||||||
| What is the chemical compatibility of Amicon Ultra? | Amicon Ultra units are intended for use with biological fluids and aqueous solutions. Please refer to the user guide, catalogue, or contact Technical Support. | ||||||||||||
| Can Amicon Ultra units be sterilized with ethanol? | Amicon Ultra is compatible with 70% Ethanol, but we have not done any studies to test for sterilization. |
