Let’s Dive into Whatman Anodisc 13 Supported Membrane Filters, Whatman 6809-6022, Pack of 50
In the world of critical filtration, precision and reliability are paramount. That’s why the Whatman Anodisc 13 Supported Membrane Filters, Whatman 6809-6022, Pack of 50 caught my attention. These aren’t your everyday coffee filters; we’re talking about a high-precision tool for lab work, environmental monitoring, and any situation where absolute purity and consistent results are non-negotiable.
My work frequently involves analyzing water samples for particulate contamination. The existing methods often introduced their own variables, making accurate analysis a challenge. I needed a filter that would provide consistent pore size, minimal interference, and a robust structure to handle various solvents.
Upon unboxing, the Whatman filters immediately impressed with their quality. The annular polypropylene ring provided a solid support for the delicate Anopore membrane. They felt substantial, not flimsy, suggesting careful manufacturing and quality control.
Compared to standard cellulose acetate filters and even some PTFE membranes I’ve used, the Whatman Anodisc 13 filters felt significantly more robust. The consistent pore size promised better accuracy, unlike the variable results sometimes encountered with cheaper alternatives. My initial reaction was optimistic – these looked like they could solve my accuracy and consistency issues.
Real-World Testing: Putting Whatman Anodisc 13 Supported Membrane Filters, Whatman 6809-6022, Pack of 50 to the Test
First Use Experience
My initial testing took place in our lab, filtering water samples from various field locations. I used a standard vacuum filtration apparatus. The Whatman Anodisc 13 filters performed exceptionally well.
The filters were subjected to a series of tests, including filtration of samples with high sediment loads. I also filtered samples with high organic content. The membrane held up beautifully, with no signs of tearing or collapse, unlike some other filters I’ve used which can clog quickly or even burst under pressure.
The Whatman Anodisc 13 filters were notably easy to use, fitting snugly in the filtration apparatus. I experienced no issues with leaks or improper sealing. There was a slight learning curve in optimizing vacuum pressure, but that was due to my equipment, not the filters themselves.
A notable surprise was the transparency of the membrane when wet, making microscopic examination of retained particles incredibly easy. I didn’t need to transfer the samples. This significantly sped up my analysis process.
Extended Use & Reliability
After several weeks of consistent use, the Whatman Anodisc 13 filters have proven remarkably reliable. They maintain their integrity and filtration efficiency even after repeated use. There has been no discernible degradation in performance.
I’ve noticed minimal wear and tear. The polypropylene ring remains firmly bonded to the membrane. The filters exhibit great chemical resistance when exposed to various solvents, which is crucial for lab work.
Maintenance is straightforward; a simple backflush with distilled water keeps the filters clean. The filters are easily cleaned and dried, ensuring accurate and repeatable results over time. Compared to previous filters, these outperform in terms of durability and ease of maintenance.
Breaking Down the Features of Whatman Anodisc 13 Supported Membrane Filters, Whatman 6809-6022, Pack of 50
Specifications
The Whatman Anodisc 13 Supported Membrane Filters, Whatman 6809-6022, Pack of 50 boast several key specifications that contribute to their exceptional performance. The 0.2 µm pore size provides excellent retention of bacteria and fine particles, ensuring the filtrate is free of contaminants.
The 25 mm diameter is a standard size, compatible with most filtration setups, and the pack of 50 offers a good balance between quantity and shelf life. The Whatman No.: 6809-6022 uniquely identifies this specific product. The peripherally bonded annular polypropylene ring gives added support and prevents membrane tearing or collapsing.
These specifications are not arbitrary; they directly impact the filter’s ability to perform its job effectively. The consistent pore size means more accurate and repeatable results. The robust construction minimizes the risk of failure during filtration, saving time and resources.
Performance & Functionality
