WHATMAN Cellulose Chromatography Paper, Grade 1, 20mm x 100M

The WHATMAN Cellulose Chromatography Paper, Grade 1, is a high-purity, 100% cotton linter paper designed for general laboratory use in analytical and research environments.

Measuring 20mm in width and 100 metres in length, this chromatography roll is ideal for a variety of qualitative analytical techniques, including chromatography separations and protein blotting applications. It is supplied in a single roll per pack, offering flexibility in use and minimal wastage.

Material & Composition

Manufactured from pure cellulose derived from high-quality cotton, this chromatography paper is engineered to deliver consistent performance. The paper exhibits uniform texture and high absorbency, allowing for predictable capillary action and flow characteristics. Its low ash content ensures minimal interference in analytical processes, maintaining integrity during sensitive experimental procedures.

Performance Characteristics

This chromatography paper features a thickness of 0.18mm and a basis weight of approximately 87g/m². It provides medium flow rates (approximately 130mm/30 minutes with water), making it suitable for a wide range of separation techniques.

The smooth surface facilitates sample application and migration, thereby enhancing the resolution and clarity of the results. The consistent flow properties support reliable reproducibility in both qualitative and quantitative assays.

Applications

This chromatography paper is widely used in general analytical separations, blotting of nucleic acids and proteins, and electrophoresis sample support. Its compatibility with a broad spectrum of solvents and reagents makes it a preferred choice in biochemical and life science laboratories. The roll format enables custom sizing and versatile laboratory use, especially in workflow-specific procedures.
