Let’s Dive into Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-090, Pack of 100
In the demanding world of field research and tactical operations, reliable filtration is paramount. The Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-090, Pack of 100 steps in as a specialized solution. These papers, manufactured by Whatman, are designed for separating aqueous and organic phases, particularly useful in situations where traditional lab equipment is unavailable or impractical.
My interest in this product stemmed from a recurring challenge during extended backcountry medical training exercises. We needed a reliable way to quickly analyze urine samples for signs of dehydration and infection without carrying bulky laboratory equipment. I was searching for a lightweight, disposable solution that could efficiently separate urine components, and the water-repellent and phase-separating properties of the Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-090, Pack of 100 seemed promising.
Upon receiving the pack, my initial impression was one of professional quality. The papers are uniformly cut, thin yet durable, and visibly treated to repel water. Compared to standard filter paper, which would quickly become saturated and ineffective in separating phases, these Whatman papers felt like a purpose-built tool.
I considered using standard coffee filters or even improvising with tightly woven cloth. However, these options lacked the Whatman paper’s guaranteed pore size and controlled separation properties. My initial excitement came from the potential time savings and accuracy this specialized paper could offer in critical field scenarios.
Real-World Testing: Putting Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-090, Pack of 100 to the Test
First Use Experience
My first test of the Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-090, Pack of 100 took place during a simulated search and rescue operation in a humid, forested environment. I needed to rapidly assess a simulated casualty’s hydration status via a urine sample. The paper was folded into a cone shape and placed inside a makeshift funnel constructed from a cut water bottle.
The performance was impressive. The urine quickly passed through the paper, leaving behind the larger, potentially interfering particles. The water-repellent coating worked exactly as intended. There was no excessive saturation or disintegration of the paper, even in the high-humidity conditions.
Using this method significantly streamlined the assessment process compared to waiting for gravity to do its work with standard filter paper. The biggest surprise was the paper’s ability to maintain its integrity even after repeated use with multiple samples.
Extended Use & Reliability
After several weeks of incorporating the Whatman paper into our training scenarios, its reliability became increasingly apparent. Even after being stored in a damp medkit for days, the papers retained their water-repellent properties. Minimal wear and tear was noticed during the testing.
The paper is essentially disposable, requiring no specific cleaning. Storing them in a waterproof bag or container is advisable to prevent damage from moisture or physical abrasion. In contrast to previous attempts with improvised filtration methods, the Whatman paper offered consistent, predictable results. This outperformed anything I’d previously tried in the field.
