ASTRA® C18-HE UHPLC column, 2.0 µm 50 mm × 2.1 mm, AST-5732-TG21

SKU: AST-5732-TG21
Manufacturer: Chromservis

The ASTRA® brand extends new line of the ARION® HPLC columns. 

  • Strict quality control of alkaline and heave metals content during silica gel production process (<10 ppm)
  • Narrow particle size and pore volume/size distribution
  • Unique production process ensuring high lot-to-lot reproducibility
  • High end-capping in gaseous phase

Main particle characteristics:

  • High proximity to the circle
  • Surface smoothness
  • Tight particle size distribution
  • No broken particles
  • No presence of clustered particles
  • No “Moon craters or mountains”
