The Science of Filpaco Lab Filter Paper

Filpaco Lab Filter Paper, produced by Great Lakes Filters, is engineered for high-performance laboratory filtration, combining mechanical and adsorptive filtration mechanisms to ensure precise particle removal and chemical compatibility. This makes it an essential tool in life sciences, pharmaceuticals, and analytical laboratories.

Filtration Mechanisms

Filpaco filter paper functions as a depth filter, trapping larger particles mechanically while adsorbing smaller contaminants via surface interactions. The random fiber matrix provides multiple pathways for fluid flow, enhancing particle retention. High-purity alpha-cellulose composition ensures minimal extractables and interference in analytical applications.

Mechanical Filtration: Retains particles based on size, making it ideal for clarifying solutions and precipitate collection.
Adsorptive Filtration: Captures smaller particles via electrostatic and hydrogen bonding interactions, improving retention of fine contaminants like colloids or trace organics.

Chemical Compatibility & Structural Advantages

Filpaco filter papers offer broad chemical resistance, making them suitable for aqueous solutions, organic solvents, and even strong acids and bases. Specialized grades such as hardened ashless filters can withstand harsh chemical environments without degradation.

Key material benefits:

High wet strength – resists tearing, even when saturated.
Ultra-low ash content – ensures purity for gravimetric and quantitative analysis.
Uniform absorption & wicking properties – critical for chromatography and blotting applications.

Applications in Life Sciences & Laboratories

Analytical Filtration: Sample clarification, gravimetric analysis, and pharmaceutical testing.
Microbiology & Biotech: Prefiltration before sterile membrane filtering, antibiotic assay discs, and cell culture media filtration.
Chromatography & Blotting: Used as stationary phases, wicking materials, and transfer supports in molecular biology.
Vacuum Filtration: Compatible with Büchner funnels, available in pre-folded and custom-cut shapes for efficiency.
