Grade 54

Whatman Grade 54 hardened low ash quantitative filter paper is designed for efficient and rapid vacuum filtration, particularly suited for recrystallization and handling of coarse and gelatinous precipitates.

Key Features:

Hardened and Smooth Surface: The filter paper is hardened and has a smooth surface, facilitating fast vacuum suction filtration and making it ideal for rapid and efficient processing.
High Wet-Strength: It maintains its integrity and strength even when wet, allowing for the collection of precipitates without compromising the filter’s performance.
Minimal Fiber Shredding: Designed to shed minimal fibers, which is crucial for avoiding contamination in sensitive applications.
Fast Filtration: Optimized for speed, making it effective for applications that require quick filtration, such as recrystallization.
Low Ash Content: The low ash content contributes to minimal contamination and reliable analytical results.

Applications:

Recrystallization: Excellent for processes that involve recrystallization, where fast and efficient filtration is needed to handle coarse and gelatinous precipitates.
Büchner and Hirsch Funnel Filtration: Ideal for use with both Büchner and Hirsch funnels, where its properties enhance performance and reliability.

Whatman Grade 54 filter paper offers high wet-strength and a smooth surface for rapid and efficient vacuum filtration. Its ability to handle coarse and gelatinous precipitates with minimal fiber shedding makes it a valuable choice for recrystallization and other applications requiring fast filtration.
