General description
Grade 4 Chr cellulose chromatography roll is a 0.21 mm paper for routine and/or repetitive chromatography when loadings are relatively low. Thickness 0.21 mm. Flow rate 180 mm/30 min. Fastest of the thin papers. Recommended for routine and/or repetitive chromatography when loadings are relatively low. Smooth surface. Very suitable where speed is important and very high resolution is not required.
Features and Benefits
- Pure cellulose produced entirely from the highest quality cotton linters with no additives of any kind.
- Manufactured and tested specifically for chromatographic techniques. This ensures the wicking capability and uniformity of capillary action that are important in chemical separations.
- Also widely used in protein and nucleic acid blotting.
