Key Applications
This versatile filter paper finds use in:
- Qualitative analytical procedures
- General laboratory filtration
- Educational experiments
- Industrial process monitoring
- Environmental sample preparation
Why This Filter Paper Stands Out
Whatman’s reputation for quality is built into every sheet of Grade 43 filter paper. The medium retention rate (approximately 16 microns) makes it ideal for applications where you need to capture fine particles without sacrificing flow rate. The pure cellulose composition ensures minimal interference with your samples, while the consistent thickness provides uniform filtration performance.
For students and researchers working on tight budgets, this filter paper offers excellent value without compromising on quality. The pack of 100 sheets ensures you’ll have an ample supply for multiple experiments.
Choosing the Right Size
Selecting the appropriate diameter is crucial for your filtration setup:
- 9cm and 11cm: Perfect for small-scale experiments and educational labs
- 12.5cm: The most versatile size for general lab use
- 15cm: Ideal for larger volume filtrations
- 18.5cm: Best for industrial applications and high-volume samples

Proper Usage Tips
To get the best results from your Whatman Grade 43 filter paper:
- Always handle with clean forceps to avoid contamination
- Pre-wet the paper with solvent for better adhesion in funnels
- Use appropriate funnel size to match your filter paper diameter
- Store in a clean, dry environment to maintain integrity
- Dispose of used papers according to your lab’s waste management protocols
Safety Considerations
While cellulose filter paper is generally safe to handle, always follow standard lab safety practices:
- Wear appropriate PPE when handling chemical solutions
- Avoid inhaling any particles that may become airborne
- Dispose of used filter papers properly, especially after chemical filtration
FAQs
What is the particle retention size for Whatman Grade 43 filter paper?
Whatman Grade 43 filter paper has a medium retention rate of approximately 16 microns, making it suitable for general laboratory filtration tasks.
Can I use this filter paper for quantitative analysis?
While primarily designed for qualitative analysis, Grade 43 can be used for some quantitative applications where high precision isn’t critical. For strict quantitative work, consider Whatman’s ashless grades.
How should I store my filter paper to maintain quality?
Store your filter paper in its original packaging in a cool, dry place away from direct sunlight and chemical fumes. This preserves the paper’s integrity and prevents contamination.
Is this filter paper compatible with organic solvents?
Yes, Whatman Grade 43 cellulose filter paper is compatible with most common organic solvents used in laboratory applications.
What’s the difference between Whatman Grade 43 and other grades?
Grade 43 offers medium retention and flow rate, making it more versatile than finer grades like 42 but with better retention than coarser grades like 1. It’s ideal for general-purpose filtration where you need a balance between speed and particle capture.
