Let’s Dive into Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100
The Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100 might not be the first thing that comes to mind when thinking about outdoor or tactical gear, but its versatility and reliability make it an indispensable tool for various applications in the field. Manufactured by Whatman, a trusted name in laboratory filtration, this filter paper offers a blend of absorbency and retention ideal for water purification, soil analysis, and even fire starting in survival scenarios. Let’s delve into why this seemingly mundane lab supply has earned a place in my pack.
My initial interest stemmed from a need to filter water sources in remote areas where readily available clean water was scarce. Traditional water filters can be bulky and prone to failure, so I was searching for a lightweight, biodegradable backup option. The promise of a medium porosity and 8 µm particle retention in the Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100 intrigued me, suggesting it could effectively remove larger sediment and debris from water before further purification methods.
Unboxing the Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100 revealed exactly what I expected: a pack of 100, 18.5 cm diameter circular filter papers. The papers felt substantial, not flimsy, indicating a good level of wet strength. There were no immediate signs of damage or poor manufacturing, giving me confidence in their potential.
Compared to using a bandana or cloth for pre-filtering, which I’ve done in the past, the Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100 offers a consistent pore size and higher filtration efficiency. While a dedicated backpacking filter like a Sawyer Squeeze offers superior filtration down to 0.1 microns, it comes with a higher price and added complexity. My decision to try the Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100 was driven by its simplicity, packability, and multi-use potential.
I was cautiously optimistic. The Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100 isn’t a flashy piece of gear, but its potential utility in water filtration and other field applications piqued my interest. I was eager to see how it performed under real-world conditions.
Real-World Testing: Putting Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100 to the Test
First Use Experience
My first test involved a stream during a three-day hiking trip in the Appalachian Mountains. I fashioned a simple filtration system by placing the Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100 inside a small, portable filter funnel and slowly pouring water from the stream through it into my water bottle. The paper effectively removed visible sediment and larger organic matter, leaving the water significantly clearer.
The Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100 performed remarkably well even in slightly turbid water conditions. The flow rate was manageable, slower than just pouring the water, but much faster than I expected. I noticed no tearing or disintegration of the paper, even when damp.
It took a few tries to get the paper properly seated in the funnel without collapsing, but once I found the right technique, the process was straightforward. The biggest surprise was how much cleaner the water looked after just this simple filtration step.
Extended Use & Reliability
After several weeks of use during various outdoor activities, the Whatman Grade No. 2 Filter Paper, Whatman 1002-185, Pack of 100 has proven to be a reliable addition to my gear.
