    Cellulose Acetate SELECA-V
     
    Seleca-V cellulose acetate is specially made for electrophoresis:
  • High purity membrane leaves almost no residue at application point; sharp separation with low varability
  • This cellulose acetate membrane is not for filtration. Click here for information on cellulose acetate membranes for filtration.
  • Produce consistent, reproducible results with minimal sample volume
  • Available in plain, white 60x220mm sheets
  • Use to confirm products by electrophoresis, in conjunction with TLC, PC, etc.
