Whatman Anodisc 6809-7013 Unsupported Membrane Filters, 100 Pack Review

How the Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7013, Pack of 100 Changed My Routine

The Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7013, Pack of 100 from Whatman are designed for critical filtration needs in laboratory environments. These filters promise consistent pore size and compatibility with a wide array of solvents, making them a staple in research and quality control. My initial encounter with these filters arose from a persistent challenge in our environmental testing lab – inconsistent particulate analysis.

I was tasked with finding a reliable filtration method to ensure accurate data. The bane of my existence was inconsistent results from previous filters, which led to wasted samples and skewed analyses. This necessitated a filter with precise pore size and minimal background interference.

Unboxing the Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7013, Pack of 100, I immediately noted the meticulous packaging. Each filter was individually separated, minimizing potential contamination. The rigidity of the filters was also promising, hinting at robustness.

Previously, we had been using Millipore filters and generic cellulose acetate options. The Millipore filters were often pricier for the same level of performance, while the cellulose acetate filters lacked the solvent compatibility needed for some of our more aggressive sample preparations. The Whatman Anodisc filters offered a seemingly perfect balance of price and functionality.

My initial excitement was cautiously optimistic. I’ve been burned before by promising lab equipment. However, the reputation of Whatman combined with the specific benefits of the Anodisc membrane gave me hope for a breakthrough.

Real-World Testing: Putting Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7013, Pack of 100 to the Test

First Use Experience

My first application of the Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7013, Pack of 100 was in analyzing river water samples for heavy metal content. We were conducting a study on industrial runoff and its impact on the local ecosystem. The filters were placed in a standard vacuum filtration setup, and I processed approximately 50 samples over a single day.

The filters performed consistently across all samples, even with varying turbidity levels. Their ability to withstand both aqueous and organic solvents was crucial for our sample preparation protocol, which involved multiple extraction steps. Using these filters was remarkably simple; I didn’t experience any clogging or tearing, even when dealing with sediment-rich samples.

I was initially concerned about potential leaching, but the Whatman Anodisc filters lived up to their reputation. Post-filtration analysis showed no detectable interference from the filter material itself. This was a major win.

Extended Use & Reliability

After several weeks of continuous use, the Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7013, Pack of 100 have proven to be remarkably reliable. We’ve used them in a wide range of applications, from protein purification to nanoparticle separation. They have performed consistently well.

Durability hasn’t been an issue. The filters show no signs of degradation, even after repeated exposure to harsh chemicals. Maintenance is minimal; a simple rinse with distilled water is usually sufficient for cleaning.

Compared to our previous filters, the Whatman Anodisc filters have significantly reduced variability in our results. This has increased the confidence in our data. We have reduced the need for repeated tests. They have genuinely streamlined our workflow.
