Let’s Dive into Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7023, Pack of 100
The Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7023, Pack of 100, manufactured by Whatman, are a critical component for anyone involved in serious filtration and microscopy. These filters promise high-quality separation and analysis, and with 100 filters in a pack, they seem poised for extended laboratory use. Their unsupported design and compatibility with various solvents make them an interesting option.
My work in environmental testing often demands precise filtration. I needed filters that could handle various aqueous solutions and organic solvents without compromising integrity. I’d previously struggled with filters that either clogged too easily or reacted with my samples, throwing off results.
Upon unboxing the Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7023, Pack of 100, I immediately noticed their thin, almost translucent appearance. The material felt robust, despite its delicate nature. They were neatly packaged, minimizing any chance of damage during shipping, reflecting Whatman’s commitment to quality.
Compared to standard cellulose filters and even some nylon membranes I’ve used, the Whatman Anodisc filters felt significantly different. The cellulose filters often introduced unwanted fibers into the filtrate. The nylon membranes sometimes displayed inconsistent pore sizes. I chose the Whatman Anodisc for its reputation for uniform pore size and minimal background interference, hoping to improve the accuracy of my microscopic analyses.
My first impression was cautiously optimistic. The filters felt professional and well-made. The high price tag did raise my expectations, but I was eager to see if their performance justified the investment.
Real-World Testing: Putting Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7023, Pack of 100 to the Test
First Use Experience
I first tested the Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7023, Pack of 100 in our lab while processing water samples from a nearby river known for its industrial runoff. The goal was to isolate and identify microplastics and bacterial contaminants.
The conditions were fairly standard laboratory settings, with controlled temperature and humidity. The initial filtration process was noticeably faster than with the cellulose filters I had been using. There was less clogging, even with relatively turbid samples.
Using the Whatman Anodisc filters required a bit of adjustment due to their unsupported nature. Unlike supported membranes, these require careful handling and appropriate filter holders to prevent tearing or distortion during vacuum filtration. Once I got the hang of it, the process was smooth and efficient.
A minor issue arose when filtering a particularly viscous sample containing high concentrations of algae. The filter did clog eventually, but it handled a significantly larger volume than I expected before needing replacement. This underscored the importance of pre-filtering highly particulate-laden samples to maximize the Anodisc’s lifespan.
Extended Use & Reliability
After several weeks of consistent use, the Whatman Anodisc Unsupported Membrane Filters, Whatman 6809-7023, Pack of 100 continued to perform reliably. I’ve processed hundreds of samples with minimal issues.
The filters have shown no significant signs of degradation or wear and tear. Even after autoclaving for sterilization, the pore size and integrity remained consistent.
Maintenance is straightforward; pre-filtering samples and proper storage are key. Occasional cleaning of the filter holders is necessary to prevent cross-contamination, but the filters themselves are disposable, making the overall process relatively hassle-free.
Compared to my previous experiences, the Whatman Anodisc filters have significantly outperformed other options in terms of flow rate, minimal background interference, and overall reliability. The consistent pore size has also greatly improved the quality and accuracy of my microscopic analyses.
