Why whatman paper is not handled by naked hand?

Whatman paper is often not handled by naked hands to prevent contamination from oils, dirt, and moisture that can transfer from skin to the paper. These contaminants can interfere with analytical results, especially in sensitive applications like chromatography or filtration. Additionally, handling with bare hands can lead to physical damage or degradation of the paper's quality. Using gloves or tweezers helps maintain the integrity and purity of the paper for precise scientific work.
