Product Overview
Whatman Grade 2727 Chromatography Paper is a high-performance cellulose paper engineered for consistent, reproducible results in paper chromatography applications. Manufactured from 100% pure cotton linters, this medium-flow paper delivers a balanced combination of retention and separation efficiency, making it a trusted choice for laboratories requiring precision. The uniform texture and high wet strength ensure minimal background interference, while the optimized pore structure facilitates smooth solvent migration. Its neutral pH and low ash content further enhance reliability in qualitative and semi-quantitative analyses. The paper undergoes stringent quality control to maintain batch-to-batch consistency, eliminating variability in experimental outcomes. Available in multiple sheet sizes, it adapts seamlessly to diverse chromatographic setups, from small-scale experiments to larger separations. The medium flow rate (approximately 130 mm/30 min) strikes an ideal balance between speed and resolution, reducing run times without compromising clarity. Compatible with a wide range of solvents, including water, alcohols, and organic mixtures, this paper accommodates various mobile phases while maintaining structural integrity. Its smooth surface minimizes tailing effects, ensuring sharp, well-defined separation zones for accurate interpretation. The absence of additives or binders guarantees purity, preventing artifact formation that could skew results. Whether used in ascending, descending, or radial chromatography, Whatman 2727 delivers dependable performance, supporting reproducible data across repeated trials. Its versatility extends to educational demonstrations, where its consistent behavior helps standardize teaching protocols. The paper?s archival stability ensures long-term storage without degradation, preserving its properties until use. For laboratories prioritizing accuracy and efficiency, this chromatography paper represents a cost-effective solution that reduces waste and rework. The pack sizes cater to varying throughput needs, from individual research projects to high-volume academic labs, optimizing inventory management. As a staple in chromatographic workflows, Whatman 2727 maintains its reputation as a benchmark for quality, combining traditional craftsmanship with modern manufacturing precision.
FAQs
1. What is the typical flow rate of Whatman Grade 2727 paper?
The flow rate for Whatman 2727 is approximately 130 mm in 30 minutes under standard conditions, making it a medium-speed chromatography paper suitable for most separations.
2. Can this paper be used with acidic or basic solvents?
Yes, Whatman 2727 is compatible with a wide pH range (typically 1?10), though extreme pH conditions may affect its structural integrity over prolonged exposure.
3. How should I store unused sheets to maintain their quality?
Store the paper in its original packaging or an airtight container at room temperature, away from direct sunlight, moisture, and volatile chemicals to prevent contamination or degradation.
