High Performance & High Capacity Columns puriFlash HP, High Performance Spherical silica has superior flow properties when compared to irregular shaped, flash grade silica. PuriFlah HPcolumns are packed with either 15, 30 or 50µ spherical silica. Columns are available from 4g to 1.6kg and are compatible with any flash system.   puriFlash HC, High Capacity PuriFlash HC, is the big brother of puriFlash HP. It is an ultra-high surface area silica. When it comes to large scale purification, loading is a critical factor. The example below shows that purity is easily achieved with a 20% sample load. Available in bulk and all column sizes from 4g to 1.6kg. Column Selection Guidelines Silica Grade Particle Size Suggested Use 50SIHC 50µ Every Day Use, High Capacity 50SIHP 50µ Every Day Use 30SIHP 30µ When you need a little Oomph* 15SIHP 15µ Guaranteed Separation * Oomph: Vigor, liveliness, get up and go.

puriFlash HP columns

Speed AND Resolution. Have it All with PuriFlash HP Columns!

With puriFlash HP columns, speed and resolution are achieved by using spherical silica, steeper gradients and higher flow rates without increased backpressure. Flash purification is now 3x faster!

• Save time by collecting fewer fractions
• Faster throughput via higher flow rates
• Reduce solvent consumption
• 15µ for difficult separations
• Lower pressure with spherical silica
• 30 bonded phases; reverse phase,
  ion exchange and more!
• Use on ANY flash system

High Speed Columns - PuriFlash

Interchim provides columns packed with highly efficient spherical silica.
The 15µ and 30µ columns improve resolution and reduce run times by up to 70%.

Spherical silica has superior flow properties when compared to irregular shaped, flash grade silica. As a general rule, 30µ puriFlash and 40-60µ flash grade silica have similar pressure values.

PuriFlash columns are packed with either 15, 30 or 50µ particles. Columns are available from 4g to 1.6kg and are compatible with any flash system.
