The NEW Way to Concentrate Proteins

Say goodbye to tedious centrifugation.
The Proteus X-Spinner™ Ultrafiltration Devices are the breakthrough solution for rapid protein and nucleic acid concentration.
 
 

Incredibly Fast Concentration, No Centrifuge Required!

Protein Ark innovative Pressure Caps allow you to concentrate your samples with ease, leaving centrifuge-based methods in the past.
Watch your sample concentrate in real-time. Get exceptional results, faster than ever before. 
 
The Proteus X-Spinner™ devices harness the power of reverse flow and a large membrane surface area to deliver:
• Incredibly fast processing – complete a 10-minute protocol with the X-Spinner 8 model
• Outstanding sample recovery – as a result of the reverse mechanism and gentle concentration
 

Choose the X-Spinner Model to Suit Your Needs

X-Spinner 8
 
• MWCO available: 3, 10, 30 or 100 kDA
• Min. volume: 1 ml
• Max. volume 8 ml
 
 X-Spinner 20
 
• MWCO available: 3, 10, 30 or 100 kDA
• Min. volume: 5 ml
• Max. volume 20 ml
 
 
Applications Include:
 
• Ultrafiltration of proteins
• Protein and DNA desalting/buffer exchange
• Recovery of genomic DNA
• Concentration of nucleic acid
• Removal of contaminants
• Removal of imidazole 
 

Key Features:

• No centrifuge needed with specially designed Pressure Caps
• Ready to use; just add sample and pump
• Ideal for sample volumes from 1 ml to 20 ml
• Concentrate up to 150 foldNo cross contamination; enclosed unit
• Ultra-low absorption membranes
• Ultrafiltration reversed preventing any membrane blockage
• Particle laden samples and “sticky” proteins can be usedInverse orientation results in very rapid filtration (as little as 10 minutes)
• Large dead stop; no risk of drying sample
• Multi-use, if kept wet
