Whatman™ Grade 4V Qualitative Filter Paper is a pre-folded (fluted) version of Whatman Grade 4, specifically engineered for very fast filtration and high loading capacity. Manufactured by Cytiva, this filter paper is optimized for applications where speed is critical and fine particle retention is not required.

With a nominal particle retention of 20–25 µm and an exceptionally fast filtration speed (Herzberg ~37 s), Grade 4V is ideal for filtering coarse particles, gelatinous precipitates, and viscous samples, making it a preferred choice in high-throughput laboratory environments.

Key Features

Very Fast Flow Rate – Minimizes filtration time for rapid sample processing
Pre-Folded (Fluted) Design – Ready-to-use, increases effective filtration area
Coarse Particle Retention (20–25 µm) – Ideal for non-critical fine filtration
High Loading Capacity – Handles heavy particulate and viscous samples efficiently
Optimized for Gravity Filtration – Compatible with standard conical funnels
Reliable Whatman Quality – Consistent performance across applications

Applications

Filtration of coarse and gelatinous precipitates
Rapid clarification of biological fluids
Filtration of organic extracts prior to analysis
General laboratory filtration where speed is prioritized
Environmental and industrial sample preparation
Food and beverage sample clarification
High-throughput workflows in routine laboratories

Whatman™ Grade 4V filter paper is designed for laboratories that prioritize speed and throughput over fine particle retention. Its fluted design significantly increases filtration surface area, resulting in rapid liquid flow and reduced clogging, even when working with high particulate loads or viscous samples.

Compared to Grades 1V and 2V, Grade 4V offers the fastest filtration performance, making it especially suitable for pre-filtration, bulk sample processing, and applications involving gelatinous or coarse materials.
