A Close Look at the Whatman Polycap HD Disposable Filter Capsules, Whatman 6703-3610 Polycap 36 Hd
The Whatman Polycap HD Disposable Filter Capsules, Whatman 6703-3610 Polycap 36 Hd are designed for applications demanding both high filtration efficiency and significant loading capacity, making them a seemingly ideal solution for filtering challenging or dirty solutions. Manufactured by Whatman, a trusted name in laboratory filtration, these capsules promise convenience and reliability, aiming to streamline processes while ensuring purity. The all-polypropylene construction is touted to allow use with broad ranges of pH, temperature, time, and pressure, adding to its versatility.
My journey to discover the Whatman Polycap HD Disposable Filter Capsules, Whatman 6703-3610 Polycap 36 Hd began when I was tasked with optimizing the filtration process for a particularly stubborn batch of field samples. These samples, notorious for their high particulate content, were clogging standard filters at an unacceptable rate, thus extending processing times and increasing consumable costs. I was looking for a filter capsule that could handle high particulate loads without sacrificing filtration efficiency or purity.
Upon receiving the Whatman Polycap HD Disposable Filter Capsules, Whatman 6703-3610 Polycap 36 Hd, my first impression was that of a well-engineered, robust unit. The capsule felt solid and well-sealed, inspiring confidence in its ability to withstand the pressures of demanding filtration tasks. The manual vent with Luer lock was a clever addition, hinting at versatility beyond simple filtration.
Compared to similar disposable filter capsules from Millipore and Sartorius, the Whatman stood out due to its higher filtration area (400 cm2) for a similarly sized capsule, potentially offering longer filter life with heavily contaminated samples. While Millipore capsules offered comparable filtration performance, the Whatman’s all-polypropylene construction seemed more resistant to a broader range of chemical solvents and pH levels, making it a safer choice for the variety of samples my lab processes. I chose the Whatman for its combination of high capacity, broad chemical compatibility, and reputation for reliability.
My initial reaction was cautiously optimistic. I was excited about the potential for increased throughput and reduced downtime, but also aware that real-world performance often differs from manufacturer claims. I was eager to put it through its paces.
Real-World Testing: Putting Whatman Polycap HD Disposable Filter Capsules, Whatman 6703-3610 Polycap 36 Hd to the Test
First Use Experience
I first tested the Whatman Polycap HD Disposable Filter Capsules, Whatman 6703-3610 Polycap 36 Hd with a batch of soil samples collected from a heavily contaminated site.
