Product Description
When precision matters in your lab work, Whatman Grade 50 filter paper stands out as a reliable choice for researchers, students, and educators. Engineered from 100% pure cotton linters, this qualitative filter paper offers a balanced combination of flow rate and particle retention, making it ideal for a wide range of laboratory applications.
Whether you’re filtering aqueous solutions, conducting qualitative analysis, or preparing samples for further testing, Grade 50 delivers consistent results. Its medium filtration speed ensures efficient processing without compromising clarity, while its high purity minimizes interference in sensitive experiments.
Available in multiple sizes, from small 4.25 cm circles to large 46×57 cm sheets, this filter paper adapts to various experimental setups. The uniform thickness and smooth surface reduce clogging, while the acid-washed treatment ensures low ash content for cleaner filtrates.
For labs that demand dependable filtration without breaking the budget, Whatman Grade 50 is a cost-effective solution that doesn’t sacrifice quality. It’s widely used in educational institutions, research facilities, and industrial laboratories across India.

Key Applications
This versatile filter paper is commonly used for:
- General laboratory filtration of aqueous and organic solutions
- Qualitative analytical procedures in chemistry and biology
- Particle retention in environmental and food testing
- Sample preparation for spectrophotometry and chromatography
- Educational demonstrations in schools and colleges
Why This Filter Paper Stands Out
Unlike generic alternatives, Whatman Grade 50 is manufactured under strict quality controls to ensure batch-to-batch consistency. The cellulose fibers are carefully processed to maintain optimal porosity, which translates to reliable performance in critical applications.
Many researchers prefer this grade for its versatility – it’s fast enough for routine filtration yet fine enough to capture medium-sized particles. The acid-washed treatment also makes it suitable for applications requiring low metal ion content.
At eqipped, we understand the importance of having the right tools for your experiments. That’s why we offer authentic Whatman products at competitive prices, with the convenience of online ordering and nationwide delivery.
Choosing the Right Size
Selecting the appropriate filter paper size depends on your specific needs:
- Smaller diameters (4.25–11 cm) work well for test tubes and small funnels
- Medium sizes (12.5–18.5 cm) are ideal for standard laboratory funnels
- Larger circles (24–32 cm) suit Buchner funnels and vacuum filtration
- Sheet formats (15×23 cm, 46×57 cm) allow for custom cutting and bulk processing

Storage and Handling
To maintain optimal performance, store your filter paper in a cool, dry place away from direct sunlight and chemical fumes. Handle with clean, dry hands or forceps to prevent contamination. For best results, avoid touching the filtration surface.
Safety Considerations
While Whatman Grade 50 filter paper is generally safe for laboratory use, always follow standard lab safety protocols when handling filtered materials. Dispose of used filters according to your institution’s waste management guidelines.
FAQs
What is the particle retention size for Whatman Grade 50 filter paper?
Grade 50 filter paper has a particle retention of approximately 2.7 micrometers, making it suitable for medium-fine filtration tasks.
Can this filter paper be used with organic solvents?
Yes, Whatman Grade 50 is compatible with many organic solvents, though we recommend checking chemical compatibility for your specific application.
How does Grade 50 compare to other Whatman grades?
