Let’s Dive into Whatman Sharkskin General-Purpose Filter Paper, Whatman 10347521, Pack of 100
The Whatman Sharkskin General-Purpose Filter Paper, Whatman 10347521, Pack of 100 represents a seemingly simple, yet crucial tool in numerous fields, from scientific research to environmental monitoring. These aren’t your ordinary coffee filters; they are precision-engineered for consistent performance.
My work as an outdoor and tactical gear specialist often leads me to scenarios where water purification and sample collection are paramount. Clean water is essential, whether for hydration, wound cleaning, or preparing solutions.
The arrival of the Whatman Sharkskin Filter Paper was, admittedly, less exciting than a new knife or optic, but no less anticipated. Peeling back the packaging revealed 100 neatly stacked, 27.0 cm diameter circles of creped wood pulp, each possessing the promise of reliable filtration.
I’ve previously relied on standard coffee filters and improvised cloth for field filtration, but these options always left something to be desired in terms of consistency and purity. The Whatman Sharkskin Filter Paper stood out due to its promised high wet-strength and resistance to weak acids and alkalis, giving it an edge over basic filters.
My initial impression was one of quiet confidence; these weren’t flimsy, easily-torn papers. They felt robust, ready to tackle the challenges of filtering everything from murky river water to soil samples.
Real-World Testing: Putting Whatman Sharkskin General-Purpose Filter Paper, Whatman 10347521, Pack of 100 to the Test
First Use Experience
My first field test involved a water filtration exercise during a week-long survival skills course I was instructing in the Appalachian Mountains. The water source was a fast-moving stream known for its high sediment content after rainfall.
Using a simple gravity-fed filtration system I rigged up with a cut-off water bottle and some paracord, I carefully inserted the Whatman Sharkskin Filter Paper. Despite the cold, damp conditions and the pressure from the sediment-laden water, the filter paper held its integrity remarkably well.
The water that filtered through was visibly clearer than I’d expected, significantly reducing the need for pre-filtering with a bandana. There were no tears or signs of disintegration, a stark contrast to my past experiences with weaker filter options.
Extended Use & Reliability
Over the following months, I’ve integrated the Whatman Sharkskin Filter Paper into various outdoor scenarios. These included filtering collected rainwater for gardening, preparing soil samples for pH testing, and even separating debris from rendered animal fats for creating primitive soaps.
The papers have consistently held up well, showing no signs of premature wear and tear or disintegration, even when used with slightly acidic solutions. Cleaning is straightforward; typically, any remaining particulate matter can be gently brushed off after drying.
Compared to my previous reliance on makeshift filtration methods, the Whatman Sharkskin Filter Paper has proven to be a significant upgrade in terms of reliability and efficiency. The consistent pore size ensures predictable filtration rates, minimizing the risk of contaminants slipping through.
Breaking Down the Features of Whatman Sharkskin General-Purpose Filter Paper, Whatman 10347521, Pack of 100
Specifications
The Whatman Sharkskin General-Purpose Filter Paper, Whatman 10347521, Pack of 100 boasts several critical specifications:

- Whatman No.: 10347521, the unique identifier ensuring you are getting the correct product.
- Unit: Pack of 100, offering a generous supply for multiple uses.
- Porosity: Medium, striking a balance between filtration speed and particle retention.
- Flow Rate: Medium, maintaining a consistent pace without overly slowing down the filtration process.
- Particle Retention: 8–12 µm, meaning it effectively removes particles within this size range.
These specifications are paramount in practical applications because they directly impact the speed and effectiveness of filtration. A larger diameter allows for faster processing of larger volumes, while the medium porosity and flow rate provide a balance between removing particulate matter and preventing excessive clogging.
Performance & Functionality
The Whatman Sharkskin Filter Paper excels in its primary function: removing suspended solids from liquids. Whether filtering water, preparing solutions, or analyzing soil, it delivers consistent results.
The filter’s strength is its reliability, even under demanding conditions. Its one weakness might be filtering extremely fine particles; applications requiring finer filtration may necessitate a different filter with a smaller pore size. It still does meet expectations for general-purpose filtering.
Design & Ergonomics
The Whatman Sharkskin Filter Paper’s simple circular design maximizes surface area for filtration and makes it easy to handle and fold. The creped wood pulp composition provides a balance between strength and flexibility.
There is virtually no learning curve involved; it’s as simple as placing the paper in a filter funnel and pouring the liquid through. The paper is also lightweight, making it easy to pack and transport in bulk.
Durability & Maintenance
The Whatman Sharkskin Filter Paper is designed for single-use applications and it will last for a single use, as long as there are no punctures. The high wet-strength ensures it can withstand the pressure of liquid passing through without tearing or disintegrating.
Maintenance is minimal; simply discard the used filter paper after each filtration process. Proper storage in a dry place prevents the filter paper from becoming contaminated or damaged.
Accessories and Customization Options
The Whatman Sharkskin Filter Paper is primarily a standalone product and therefore doesn’t require extensive accessories. However, to perform filtration, you’ll need a filtration funnel or a similar apparatus.
Because the paper is manufactured to scientific standards, it will be compatible with any standard sized funnel, beaker or any equipment used for filtration. The 27cm diameter can also be folded to fit smaller applications.
