Effective chemotaxis requires a delicate balance between cell adhesion and migration. Nucleopore Membranes combine PVP-free polypropylene with sharp, uniform cylindrical pores to achieve both.
  • Offers a highly defined pore size cutoff in the sub-micron range, enabling particle deformity measurement and capture of extremely small particles
  • Track-etched for highly defined pore size and high pore density
  • Treated with PVP to render it hydrophilic
  • Low extractables, minimizing sample contamination risk
  • High chemical resistance and good thermal stability for a wide range of sample types
  • Low, consistent ash and low tare weights
  • Smooth flat surface for high particle visibility
