Let’s Dive into Whatman Grade 8 Ruled Special-Purpose Filter Paper, Whatman 10347009, Pack of 100
The Whatman Grade 8 Ruled Special-Purpose Filter Paper, Whatman 10347009, Pack of 100, manufactured by Whatman, might seem like a niche product to some, but for those working in food safety, pharmaceuticals, or even certain environmental testing scenarios, it’s an indispensable tool. These aren’t your everyday coffee filters; these are specifically designed for analytical work, providing consistent results and ease of use with their unique ruled grid pattern. I’ve spent over a decade dealing with gear that ranges from the tactical to the downright scientific, and I’m eager to share my insights on this seemingly simple, yet surprisingly important, lab supply.
My work often involves assessing the quality of field-harvested samples for consumption and testing water sources for contamination. Traditional filter paper can be a pain, especially when trying to quantify particulate matter; the lack of visual aids makes estimations messy and subjective. I needed a reliable, consistent method to ensure accuracy, especially when dealing with samples destined for further analysis.
Upon unboxing the Whatman Grade 8 Ruled Special-Purpose Filter Paper, Whatman 10347009, Pack of 100, the first thing I noticed was the consistent quality of the paper stock and the sharpness of the printed grid. The paper felt thicker and more durable than standard lab filters I’ve used in the past, giving me confidence it wouldn’t tear easily during wet handling. This initial impression was far more positive than my experiences with cheaper, generic alternatives.
I’ve used standard Whatman Grade 1 and Grade 4 filter papers extensively, as well as generic cellulose filters from lesser-known brands. While those filters served adequately for basic filtration, they lacked the rigidity and, more importantly, the ruled grid system that makes Whatman Grade 8 Ruled Special-Purpose Filter Paper, Whatman 10347009, Pack of 100 so appealing. The defining factor that made me chose this particular paper over other alternatives was the ruled grid, which promised to make particulate matter analysis more precise.
Initially, I was excited by the potential for more accurate analysis, but also a bit skeptical about whether the grid would interfere with the filtration process itself. The consistent grid pattern was a welcome sight and I was ready to get started.

Breaking Down the Features of Whatman Grade 8 Ruled Special-Purpose Filter Paper, Whatman 10347009, Pack of 100
Specifications
The Whatman Grade 8 Ruled Special-Purpose Filter Paper, Whatman 10347009, Pack of 100 boasts several key specifications that contribute to its specialized functionality:
- Diameter: 9.0 cm – The 9cm diameter is a common size, fitting most standard filtration funnels and apparatus. This standardized size ensures compatibility with existing lab equipment.
- Grade: 8 – This indicates a hardened, high-wet-strength paper designed for applications requiring resistance to aqueous and non-aqueous solvents. The hardening treatment increases the paper’s durability during handling.
- Ruled Grid: 5mm Green Rules – The 5mm green grid facilitates visual estimation and quantification of particulate matter retained on the filter. The grid is resistant to aqueous and non-aqueous solutions, preventing distortion or disintegration during analysis.
- Porosity: Coarse – The coarse porosity allows for fast flow rates, ideal for quickly processing samples with relatively large particulate sizes. A faster flow rate reduces processing time without sacrificing adequate particle retention.
- Flow Rate: Fast – The fast flow rate makes it efficient for filtering samples with high volumes or those requiring quick processing. This is essential for time-sensitive analyses.
- Particle Retention: 20–30 µm – This means the filter is designed to retain particles of 20 to 30 micrometers in size and larger. This is suitable for capturing a wide range of particulate contaminants commonly found in food and environmental samples.
- Material: White Cotton Linter Paper – The use of cotton linter provides a consistent, low-linting filter matrix, reducing contamination and ensuring reliable results. The hardened paper is also used for routine analysis of extraneous matter in food, beverage and pharmaceutical laboratories.
- Pack Size: 100 – The pack of 100 sheets provides a convenient supply for regular laboratory use. The pack size ensures that you’re well-equipped for numerous analyses.
