Let’s Dive into Whatman Grade 5971/2 Pleated Filter Paper, Whatman 10311847, Pack of 100
For those of us who operate outside the pristine, controlled environments of modern labs, the need for reliable filtration is often a matter of mission success, or even survival. The Whatman Grade 5971/2 Pleated Filter Paper, Whatman 10311847, Pack of 100 promises a dependable solution with its hardened cotton linter construction designed to withstand acidic and alkaline solutions, making it suitable for various field applications. I’ve spent years jury-rigging filtration systems in the field, from makeshift water purification to separating solids during improvised explosive ordnance disposal (IEDD) operations; a reliable filter paper is more than just a lab supply – it’s a critical tool.
My search for the Whatman Grade 5971/2 Pleated Filter Paper stemmed from a frustrating incident during a recent wilderness survival course I was teaching. Our primary water filtration system failed, leaving us reliant on boiling water and improvised filters made from t-shirts and charcoal; the results were… less than ideal. The promise of high wet strength and a medium-fast flow rate in these filters grabbed my attention, as it indicated a potential for efficient and robust field use.
Upon receiving the pack, the immediate impression was one of quality. The papers were neatly pleated, and the material felt substantial, hinting at the advertised high wet strength. It was a stark contrast to the flimsy coffee filters I’ve often relied on in a pinch.
I considered several other filter papers, including standard non-pleated options and cellulose-based varieties. I ultimately chose the Whatman Grade 5971/2 Pleated Filter Paper due to its purported resistance to chemical degradation and the convenience of pre-pleated design for increased surface area. The Whatman name also carries weight, suggesting a commitment to quality and consistency.
My initial reaction was one of cautious optimism. Could these filters truly perform under the duress of field conditions, or would they crumble like so many other “high-performance” pieces of gear? I was eager to find out.
Real-World Testing: Putting Whatman Grade 5971/2 Pleated Filter Paper, Whatman 10311847, Pack of 100 to the Test
First Use Experience
My first field test of the Whatman Grade 5971/2 Pleated Filter Paper took place during a five-day solo survival exercise in the high desert of Nevada. Water sources were scarce, and what I found was often silty and contaminated with algae. I utilized the filter paper in conjunction with a gravity-fed water filtration system I assembled using a hydration bladder and some PVC piping.
The Whatman filter performed admirably, even with the turbid water. The pleated design significantly increased the filtration rate compared to a flat filter. There was minimal tearing or disintegration of the paper, even after multiple uses and exposure to sediment-heavy water.
Using these filter papers proved relatively straightforward. I simply folded one into a cone shape and inserted it into my makeshift filter housing; no specialized knowledge or tools were needed. A minor issue surfaced after the first use: the fine silt tended to clog the filter, slowing the flow rate.
Extended Use & Reliability
After several weeks of use, primarily during water purification exercises and processing soil samples, the Whatman Grade 5971/2 Pleated Filter Papers continue to impress. They exhibit remarkable durability, showing minimal signs of wear and tear, even with repeated use and exposure to various contaminants. The high wet strength claim proves accurate, preventing the filters from falling apart when saturated.
Maintenance is simple: a gentle rinsing with clean water after each use helps prolong their lifespan. However, for heavily contaminated water, pre-filtering with a coarse cloth is advisable to prevent premature clogging. Compared to previous experiences with cellulose filters, these Whatman papers outperform significantly in terms of both durability and flow rate.
