| Hi-Purit™ Normal Phase Spherical, 70A/ 20-45µ Flash Cartridges |
Pore size: ~70 Å. Good for most normal phase chromatography; allows medium‑sized molecules to access internal pores (so decent surface area).
Particle size: 20‑45 µm is relatively coarse compared to some high‑performance flash (often 40‑63 µm, or finer for premium / spherical media), so the flow resistance is lower, meaning you’ll likely get faster flow, but somewhat lower resolution / more band broadening compared to finer/spherical particles.
