Let’s Dive into Whatman Grade No. 2 Filter Paper, Whatman 1002-055, Pack of 100
The Whatman Grade No. 2 Filter Paper, Whatman 1002-055, Pack of 100 might not be the sexiest piece of gear in my kit, but it’s an indispensable tool for anyone who works with liquids or needs to separate solids from liquids in the field. This unassuming pack of 5.5 cm filter papers from Whatman boasts a medium porosity, making it ideal for a wide range of applications, from clarifying water samples to performing soil tests in remote locations. It’s a lab essential that I’ve found incredibly useful beyond the sterile confines of a laboratory setting.
What led me to this product was the need for reliable water filtration in the backcountry. I needed a lightweight, packable solution to remove sediment and particulate matter from natural water sources before purification, ensuring the effectiveness of my water filters and chemical treatments.
Upon unboxing, the papers felt sturdy and well-made, surprisingly resilient for their intended purpose. The packaging was simple but effective, protecting the papers from moisture and damage during transport.
I initially considered pre-filtering options with faster flow rates, but I chose the Whatman Grade No. 2 for its balance of retention and speed. I also looked at cheaper, generic filter papers, but the Whatman brand is synonymous with quality and reliability, so I opted for the trusted name.
My first impression was positive; I was excited to test its performance in real-world conditions and see if it lived up to the Whatman reputation.
Real-World Testing: Putting Whatman Grade No. 2 Filter Paper, Whatman 1002-055, Pack of 100 to the Test
First Use Experience
I first tested the Whatman Grade No. 2 Filter Paper during a week-long backpacking trip in the Sierra Nevada mountains. I used it to pre-filter water from streams and lakes before running it through my Sawyer Squeeze water filter. The paper effectively removed silt, algae, and other debris, significantly extending the lifespan of my primary water filter.
The conditions were varied, ranging from clear, cold mountain streams to murky, algae-filled ponds. The filter paper performed consistently well in all conditions, although the flow rate was noticeably slower with the more turbid water.
The Whatman Grade No. 2 Filter Paper was incredibly easy to use; simply fold the paper into a cone, place it in a filter funnel or improvise a holder with a plastic bottle, and pour the water through. It required no special training or complicated setup.
Initially, I was surprised by how much sediment the paper could trap before clogging, a testament to its absorptive capabilities.
Extended Use & Reliability
After several months of use on various outdoor excursions, the Whatman Grade No. 2 Filter Paper continues to perform reliably. There are no signs of degradation or loss of effectiveness, even after being stored in my pack for extended periods.
The filter paper itself shows no signs of wear and tear unless subjected to excessive force when wet. The paper is delicate, so you have to exercise caution when handling it.
Maintenance is minimal; simply dispose of the used filter paper responsibly. They are technically biodegradable, but I always pack them out to minimize my impact on the environment.
Compared to previous methods of using cloth or improvised filters, the Whatman Grade No. 2 Filter Paper offers a far superior and more consistent level of filtration. The defined pore size provides more controlled results.
