Hello Jerome, here is some clarification from our product manager:   

The old naming convention was MicroStyragel, ~ 15 micron and Ultrastyragel ~10 micron.   We rebranded the columns for high resolution, high temperature and high molecular weight.  The different particle sizes have different efficiency and stability for different applications and temperatures.  

  • Styragel HR 5 micron
  • Styragel HT 10 micron
  • Styragel HMW 20 micron

  We still have a few columns labeled as Ultrastyragel as customers were dependent on them, but the Ultra and the Styragel HT are the same particle size and product.
