> Bulk silica
media for column chromatography |
|
The Whatman bulk silica media is used for low pressure columns.
Same base silica and chemistries as those used for Whatman TLC
plates. Particularly useful for scaling up separations optimized
by TLC. In addition, Whatman offers an all-purpose media for
general column chromatography. Applicable for preparative low
pressure column separations scaled up from Partisil analytical
HPLC columns.
Features and Benefits
- High resolution
- Good flow characteristics
- High surface area
