Let’s Dive into Whatman Cellulose Acetate GD/X Syringe Filters, Whatman 6901-2504, Pack of 50
As someone who’s spent over a decade wading through the weeds of outdoor and tactical gear, I’ve learned that even seemingly mundane items can be absolutely critical. When it comes to ensuring the integrity of samples in the field, or preparing solutions for sensitive equipment, reliable filtration is non-negotiable, and that’s where the Whatman Cellulose Acetate GD/X Syringe Filters, Whatman 6901-2504, Pack of 50 come into play. These filters, manufactured by Whatman, are designed for pre-filtration and clarification of difficult-to-filter samples, promising consistent results and protection for valuable analytical instruments.
My work often involves collecting water samples from remote locations, analyzing fuel quality for off-grid generators, and preparing reagents for on-site diagnostics. All require meticulously clean solutions. I was battling inconsistent results and clogged equipment due to particulate contamination.
When the package arrived, I immediately noted the professional packaging and sterile seals on each filter pack. The filters felt robust, yet lightweight, and I was optimistic about their potential for improving my workflow. Compared to cheaper, no-name filters I had used in the past, these had a visibly higher build quality. I chose the Whatman filters because of their reputation for reliability and their GD/X pre-filtration layer, hoping to reduce clogging and improve filtration speed. My initial impression was one of cautious optimism, tinged with the hope that these filters would finally solve a persistent headache in my field operations.
Real-World Testing: Putting Whatman Cellulose Acetate GD/X Syringe Filters, Whatman 6901-2504, Pack of 50 to the Test
First Use Experience
My first field test was during a remote water quality assessment in the Appalachian Mountains. I needed to filter stream water samples before running them through a portable spectrophotometer. The filters were easy to attach to a standard syringe. Even with sediment-rich water, the filtration process was noticeably faster than with previous filters I’ve used, and I didn’t experience any clogging.
The second test was during fuel analysis, prepping a sample of diesel fuel drawn from a long-stored reserve tank. The fuel was visibly contaminated with algae and particulate matter, and the Whatman Cellulose Acetate GD/X Syringe Filters handled the initial filtration without any issues, allowing me to get a clean sample ready for testing in record time.
Extended Use & Reliability
After several months of regular use across different environments, the Whatman Cellulose Acetate GD/X Syringe Filters have proven to be remarkably reliable. There are no signs of degradation in the filter media, and the housings remain intact. I clean the syringe tips and replace the filters after each use, which has kept everything running smoothly. Compared to my past struggles with cheaper filters that quickly clogged or disintegrated, the Whatman filters have significantly improved my efficiency and reduced downtime.
Breaking Down the Features of Whatman Cellulose Acetate GD/X Syringe Filters, Whatman 6901-2504, Pack of 50
Specifications
- The Whatman Cellulose Acetate GD/X Syringe Filters, Whatman 6901-2504, Pack of 50 have a 0.45 µm pore size, which is ideal for removing bacteria and fine particulate matter from samples. This pore size is a standard for many analytical applications, striking a balance between filtration speed and retention efficiency.
- These filters boast a 25 mm diameter, providing a sufficient surface area for efficient filtration of samples ranging from small volumes to around 100 mL. This diameter allows for a reasonable flow rate without requiring excessive pressure.
- Each filter is sterile, ensuring that the filtered sample remains free from contamination. This feature is crucial when dealing with sensitive biological or pharmaceutical samples, where maintaining sterility is paramount.
- The product is identified by Whatman No. 6901-2504, a unique identifier that allows for easy reordering and traceability. This number is essential for ensuring that you’re getting the correct filter for your specific application.
- They come in a pack of 50, providing a sufficient supply for moderate to high-volume usage. The pack size is suitable for laboratories or field operations that require frequent filtration.
These specifications are critical because they directly impact the quality of the filtered sample and the performance of downstream analytical instruments. A consistent pore size ensures uniform particle removal, preventing clogging and maintaining data integrity.
Performance & Functionality
The Whatman Cellulose Acetate GD/X Syringe Filters excel at their primary function: filtering samples quickly and efficiently. The pre-filtration layer significantly reduces clogging, even with heavily contaminated samples, and the 0.45 µm pore size ensures reliable removal of bacteria and fine particles. Filtration speed is notably improved compared to standard syringe filters without the GD/X pre-filter. The only slight limitation is the volume, since especially large samples might require multiple filters, though this is true of any syringe filter.
Design & Ergonomics
The design is straightforward and functional. The filter housings are made from durable plastic, and they easily attach to standard syringes. The filters are lightweight and comfortable to handle. The ergonomic design contributes to ease of use, even during extended filtration sessions.
Durability & Maintenance
The Whatman Cellulose Acetate GD/X Syringe Filters are designed for single use and are not intended for cleaning or reuse. However, the robust construction ensures that they withstand the pressures of manual syringe filtration without leaking or bursting. The durable plastic housing is resistant to most common solvents.
Accessories and Customization Options
These filters do not require any specific accessories beyond standard syringes. They are compatible with a wide range of syringe sizes and types. There are no customization options available. However, Whatman offers a variety of other filter types and pore sizes to suit different applications.
