Filter Paper 9 cm dia., 20 to 25 µm Particle Retention, P8 Grade, Coarse Porosity, Fast 160 mL/min Flow Rate

Fisherbrand cellulose filter paper is a 9 cm diameter paper filter for laboratory filtration and clarification tasks. It fits buyers who need coarse porosity with fast flow for removing larger particles in applications where low-ash or ashless paper is not required. This sheet is noted for 20 to 25 µm particle retention and a 160 mL/min flow rate.

Good Fit For

• Laboratory solution clarification
• Filtering oils
• Work with coarse or gelatinous precipitates
• Zinc analysis with Fe ppt removal

Key Features

• 9 cm diameter format for bench and lab filtration workflows
• Cellulose paper construction for general filtration tasks
• 20 to 25 µm particle retention for clarifying liquids with larger particulates
• Coarse porosity supports work with coarse and gelatinous precipitates
• Fast 160 mL/min flow rate helps move samples through quickly
• Useful where low-ash or ashless paper is not required

Applications and Usage

• Clarifying solutions in lab workflows
• Removing particles of 1 µm and larger
• Filtering coarse precipitates such as Fe(OH)3 and Al(OH)3
• Handling metallic sulfides and iron ores during filtration
• Filtering oils

Packaging and Handling

• Packaging: PK.
• Size: 9 cm.
• Material: Paper.
• Best matched to applications that do not require low-ash or ashless filter paper
• Coarse porosity and fast flow make this a better fit for larger-particle clarification than fine retention work
• Select the 9 cm diameter only if it matches your funnel or filtration setup
