The holy grail in ultrafiltration (UF) is to eliminate sample fouling and to enhance recovery and purity of target protein during the concentration or buffer exchange step. The X-spinner guarantees the best protein recoveries.
Better protein recoveries than Amicon Ultras and Vivaspins.
Ideal for dilute and viscous samples!
- Max. sample volume 2.5 ml
- Physical dead stop pocket ensuring minimum sample volume of 25 µl
- Max. 100 fold concentration
- Ultrafiltration in opposite direction to centrifugal force
The Proteus X-spinner is ideal for the following samples:
- Membrane protein (Use 100 kDa MWCO (order code: PAL-X-100-25 or PAL-X-100-100)
- Viscous samples
- Dilute protein solutions
- Sticky and hydrophobic proteins
- Protein fractions post Size Exclusion or IMAC
- De-proteinization of blood and serum samples
- Separating fee analyte or label from bound analytes/bound label
Proteus X-spinner 2.5 Features:

Why is it so good?
- 2.5 ml non-stick UF concentrator to provide the highest possible protein recoveries.
- Unique design prevents filter blocking
- Highest protein recoveries available- Guaranteed
- Viscous samples:-serum, proteins stored in 10-15% glycerol
- Dilute protein solutions:-why risk losing your protein?
- Sticky and hydrophobic proteins such as fibronectin.
- Protein fractions post Size Exclusion or IMAC
- De-proteinization of blood and serum samples
- Separating fee analyte or label from bound analytes/bound label
