Real-World Testing: Putting Whatman Polydisc TF Disposable Disk Filters, Whatman 6720-5045, Pack of 10 to the Test
First Use Experience
I tested the Whatman Polydisc TF Disposable Disk Filters in the field, filtering water samples collected from various streams and industrial runoff sites. The conditions were often less than ideal, ranging from cold, damp environments to areas with significant particulate matter in the water.
The filters performed admirably, even with heavily contaminated samples. The stepped barb connectors easily accommodated my 3/8″ tubing, and the flow rate remained consistent thanks to the integrated depth media prefilter.
The filters were incredibly easy to use. Simply connect the tubing, apply pressure, and the filtrate emerges cleanly. I encountered no issues with leakage or clogging during initial use.
Extended Use & Reliability
After several weeks of consistent use, the Whatman Polydisc TF Disposable Disk Filters continued to perform reliably. There were no signs of degradation or decreased performance, even after filtering numerous samples with varying levels of contamination.
The polypropylene housing proved to be extremely durable, withstanding the rigors of field use without cracking or leaking. Cleaning was straightforward, involving a simple flush with distilled water after each filtration.
Compared to previous experiences with less robust filters that often clogged or leaked, the Whatman Polydisc TF Disposable Disk Filters stood out for their consistent performance and durability. These have significantly streamlined my sample preparation process.
