Let’s Dive into Whatman Sharkskin General-Purpose Filter Paper, Whatman 10347511, Pack of 100
The Whatman Sharkskin General-Purpose Filter Paper, Whatman 10347511, Pack of 100 is a seemingly simple product, yet it holds significant value in various scientific, industrial, and even survival applications. Manufactured by Whatman, a renowned name in filtration, these filter papers promise reliable and consistent performance for general and high-volume filtration needs. These aren’t your grocery store coffee filters; they’re engineered for specific tasks, built with a creped wood pulp for robust filtration.
As a tactical gear specialist, you might wonder why I’m even reviewing filter paper. I often find myself needing to filter water sources in the field, or even separate particulate matter from fuel samples. This led me to search for a general-purpose filter that could handle various liquids and volumes, and the Whatman Sharkskin Filter Paper seemed like a promising option.
Upon unboxing, the first thing I noticed was the texture; the creped surface felt significantly stronger than standard filter paper. The 12.5 cm diameter seemed ideal for fitting into various funnels and filtration devices I already owned. My initial thought was, “This feels like a professional-grade tool, not just paper.”
I considered several other options, including standard Whatman Grade 1 filter paper and some generic cellulose filters. The Sharkskin paper, with its higher wet strength and resistance to weak acids and alkalis, seemed better suited for potentially harsh field conditions. I chose this one because of the combination of durability and general-purpose utility.
My first impression was definitely positive; I was excited to see how well these filters would perform in real-world conditions, pushing past simple lab experiments. I knew their performance could impact everything from my field cooking water quality to diagnosing engine fuel contaminates.
Real-World Testing: Putting Whatman Sharkskin General-Purpose Filter Paper, Whatman 10347511, Pack of 100 to the Test
First Use Experience
I tested the Whatman Sharkskin Filter Paper in two scenarios: filtering stream water during a three-day backcountry camping trip and separating sediment from a questionable batch of gasoline for a generator. The backcountry environment presented challenges like variable water clarity and the need for quick, effective filtration. The gasoline scenario presented a different issue by requiring resistance to petroleum products.
In the backcountry, the filter paper performed admirably. It efficiently removed sediment and debris from the stream water, making it significantly clearer and safer for boiling and subsequent consumption after boiling. The filter paper held up well even when processing relatively turbid water. The paper didn’t disintegrate even when damp, unlike some cheaper alternatives.
Using the Sharkskin paper with the gasoline, I observed a similar level of effectiveness. It successfully removed a noticeable amount of sediment, which would have otherwise clogged the generator’s fuel lines. There was a slight learning curve in both scenarios. Initially, I folded the paper incorrectly, leading to slower filtration. Once I optimized my folding technique for best surface area and structural support, it became efficient.
I didn’t experience any major issues, though I did learn the hard way that pre-wetting the filter paper with a small amount of the liquid being filtered helps with flow rate and prevents tearing. This drastically increased the efficiency of the whole filtering process.
Extended Use & Reliability
After several months of sporadic use, the Whatman Sharkskin Filter Paper has proven to be a reliable tool. I’ve used it to filter everything from homemade wine to used cooking oil for biodiesel experiments. There are no signs of significant wear and tear on the unused filters, and the filtered materials look clean.
The filter paper shows no degradation even after prolonged storage in a humid environment. It’s easily disposable after use, and the pack of 100 provides ample supply for various applications.
Compared to my previous experiences with standard coffee filters and less robust lab filters, the Whatman Sharkskin paper is a clear winner. It consistently outperforms in terms of filtration efficiency and durability, especially when dealing with non-water based liquids. I’m consistently impressed.
Breaking Down the Features of Whatman Sharkskin General-Purpose Filter Paper, Whatman 10347511, Pack of 100
Specifications
The Whatman Sharkskin General-Purpose Filter Paper, Whatman 10347511, Pack of 100 boasts several key specifications that contribute to its performance:
- Diameter: 12.5 cm. This size is versatile and fits well with most standard filtration funnels and setups.
- Whatman No.: 10347511. This number is essential for reordering the correct product, preventing mix-ups with similar-looking filters.
- Unit: Pack of 100. This quantity offers a balance between cost-effectiveness and preventing excessive storage of filters.
- Porosity: Medium. This pore size balances filtration speed with particle retention, making it suitable for general-purpose use.
- Flow Rate: Medium. It allows for reasonable filtration speed without sacrificing the quality of the filtration.
- Particle Retention: 8–12 µm. This specification indicates the size of particles the filter can effectively remove, crucial for achieving desired purity levels.
These specifications are important because they define the capabilities and limitations of the filter paper. The medium porosity and flow rate make it versatile for various liquids. The particle retention specification dictates the smallest particles that will be removed. The resistance to weak acids and alkalis expands the range of compatible liquids beyond just water.
Performance & Functionality
The Whatman Sharkskin Filter Paper performs its job effectively by providing reliable and consistent filtration. Its medium porosity strikes a balance between filtration speed and particle retention, making it suitable for a wide range of applications. The filters effectively separate particulate matter from liquids.
The strengths of this filter paper lie in its durability and broad compatibility. It handles various liquids, including water, solvents, and oils, without disintegrating. One area for potential improvement could be a wider range of available pore sizes.
It meets and often exceeds expectations, especially compared to generic filter papers. The high wet strength and reliable particle retention provide consistent results.
Design & Ergonomics
The Sharkskin Filter Paper’s design is straightforward but effective. Made from creped wood pulp, it offers enhanced strength compared to standard filter paper. The 12.5 cm diameter is a common size.
The filter paper is easy to handle and fold, with a slight learning curve to optimize the folding technique for maximum surface area and flow rate. It doesn’t require specialized tools or knowledge to use.
