Key Features & Benefits
✅ High-Purity Cellulose
Made from carefully selected, high-grade cotton linters with no chemical additives or binders, ensuring minimal background contamination during sensitive analytical procedures.
✅ Excellent Capillary Action
Manufactured specifically for chromatographic applications, this paper exhibits uniform wicking and capillary flow for consistent, reproducible results in chromatographic and blotting processes.
✅ Versatile Laboratory Use
- Blotting: Ideal for protein or nucleic acid blotting procedures.
- Electrophoresis: Frequently used for paper-based electrophoretic separations.
- Chromatography: Effective for planar (paper) chromatography involving a variety of solvents and analytes.
- General Chemistry: Commonly applied in qualitative chemical analysis and reagent transfer.
✅ Medium Thickness
With a thickness of approximately 0.34 mm, 3MM CHR balances good mechanical strength with fast wicking properties.
✅ Reliable Flow Rate
The paper delivers a standard flow rate of 130 mm/30 min, providing consistent migration for most solvent systems.
