MiniSpin Tubes

NuSep’s Screw Cap MiniSpin Columns are convenient tools for manipulating small volumes of affinity supports (20 to 400 µL) for protein purification.

Features of Screw Cap Spin Columns:

  • Adaptable: included Luer-Lok adaptors allow these columns to be used for syringe-based purifications
  • Column volume: 900µL
  • Resin volume: 20 to 400µL
  • Filter type: polyethylene filter, ~10µm pore size
  • Cap: O-ring screw-top caps
  • Frit options: included small & large frit options for different sample sizes

Simply add the affinity resin and sample to one of the spin columns, then use a microcentrifuge to efficiently wash away contaminants and elute your purified sample without losing any resin in the process. Spin columns allow you to affinity purify more protein in less time.
