General description
The lab standard for sub-microliter volumes. Ideal for protein, nucleic acid concentration, desalting and buffer exchange or removal of primers, linkers and unincorporated labels.
Fixed-angle microcentrifuge rotor with max. 14,000 x g.
Fixed-angle microcentrifuge rotor with max. 14,000 x g.
- Solute recoveries typically >95%, ideal for dilute (ng.mL ranger) protein solutions
- Has a deadstop for reproducible concentrate volumes
- Inverted spin method of concentrate retrieval maximizes recovery
- Low-binding Ultracel-YM membrane
- Color coding indicates MW cut-off
- Convenient sample storage of filtrate or concentrated sample in standard microcentrifuge collection tube
- Use in standard 1.5 mL tube fixed-angle rotors
