Let’s Dive into Whatman Anotop 10 and Anotop 25 Disposable Syringe Filters, Whatman 6809-1002 Anotop 10, Pack of 50
For over a decade, my work has revolved around selecting and rigorously testing outdoor and tactical equipment, and now I bring that experience to lab equipment. The Whatman Anotop 10 and Anotop 25 Disposable Syringe Filters, Whatman 6809-1002 Anotop 10, Pack of 50 promises high-quality filtration for critical laboratory applications. It caught my attention with its advertised precision, reliability, and compatibility with various solvents and aqueous materials.
My journey to this product began with the need for sterile filtration in preparing samples for sensitive analytical instruments. Specifically, I was looking for a dependable way to remove particulates from HPLC solvents to prolong column life and ensure accurate results. The Whatman filters, known for their Anopore membrane and precise pore structure, seemed like the ideal solution.
The filters arrived neatly packaged, each housed in a robust polypropylene casing with secure luer lock fittings. Immediately, the build quality felt solid, suggesting a reliable seal and minimal risk of leakage during filtration. Holding the Anotop 10, its compact size and lightweight design impressed me; this felt appropriate for processing smaller sample volumes.
Compared to other syringe filters I’ve used, like those from MilliporeSigma or Sartorius, the Whatman stood out with its specific focus on consistent pore size and minimal sample hold-up volume. I previously struggled with inconsistent filtration rates and significant sample loss with cheaper alternatives. The promise of sub-20µL hold-up volume with the Anotop 10 was a major selling point.
My initial reaction was optimistic, though tempered by the price tag of $679.99 per pack. If the Whatman Anotop 10 delivers on its claims of superior filtration and minimal sample loss, the investment would be justifiable. It was time to move beyond initial impressions and rigorously test these filters in real-world scenarios.
Real-World Testing: Putting Whatman Anotop 10 and Anotop 25 Disposable Syringe Filters, Whatman 6809-1002 Anotop 10, Pack of 50 to the Test
First Use Experience
I first tested the Whatman Anotop 10 filters while preparing mobile phase for a demanding reverse-phase HPLC analysis. The lab was undergoing significant temperature fluctuations that day due to a malfunctioning HVAC unit. My control consisted of an unfiltered sample run alongside the filtered sample.
The filtration process was smooth and consistent, even with the temperature fluctuations. The luer lock connection provided a secure seal preventing leaks, and the syringe plunger moved easily without excessive force required. I found that the filtration was significantly faster than previous filters I have used.
After the initial use, I immediately assessed the HPLC chromatograms of both the filtered and unfiltered samples. The filtered sample exhibited significantly reduced baseline noise and sharper peak resolution compared to the unfiltered control. No surprises there, but it did confirm the high-quality filtration.
Extended Use & Reliability
After using the Whatman Anotop 10 filters for several weeks in various applications, including sterile filtration of cell culture media and particle removal from protein solutions, they continue to perform reliably. Their robust construction handles repeated use without any signs of degradation. I’ve found that they are resistant to cracking and leakage.
Despite using these filters with diverse chemical solvents, there has been no evidence of membrane deterioration or leaching. I’ve taken great care to store the filters properly in their original packaging. Maintenance simply involves discarding the used filter; no cleaning is required.
Compared to previous syringe filters that suffered from clogging or inconsistent flow rates after prolonged use, the Whatman Anotop 10 consistently delivers superior performance. My previous syringe filters had a higher risk of sample contamination and waste. This level of reliability and reproducibility is critical in my lab work.
Breaking Down the Features of Whatman Anotop 10 and Anotop 25 Disposable Syringe Filters, Whatman 6809-1002 Anotop 10, Pack of 50
Specifications
The Whatman Anotop 10 and Anotop 25 Disposable Syringe Filters, Whatman 6809-1002 Anotop 10, Pack of 50 boast impressive specifications tailored to demanding laboratory environments. The precise 0.02 µm pore size ensures highly effective removal of bacteria, particulates, and even viruses from samples. This level of filtration is vital for applications requiring absolute sterility.
The Anotop 10’s 10 mm diameter is well-suited for filtering samples up to 10 mL, balancing filtration efficiency with flow rate. Its low hold-up volume of less than 20 µL minimizes sample loss, preserving precious samples for analysis or downstream processes. The Whatman No. 6809-1002 designation ensures product traceability and quality assurance.
The Anopore membrane composed of aluminum oxide ensures compatibility with a wide range of solvents and aqueous solutions. It is also inert, so there is no risk of contaminating the sample with leachables. The filters are not sterile out of the box; sterilization via autoclaving is necessary if required.
These specifications are critical because they directly impact filtration efficiency, sample recovery, and assay accuracy. The precise pore size guarantees reliable removal of contaminants. Low hold-up volume maximizes the recovery of valuable analytes.
Performance & Functionality
The Whatman Anotop 10 syringe filters excel in their primary function: providing reliable and consistent filtration. They demonstrate a high flow rate relative to similar filters with the same pore size. This reduces filtration time without compromising filtration quality.
The filters exhibit minimal back pressure during use, even when processing viscous solutions. This eases manual filtration and reduces the risk of filter rupture. The robust polypropylene housing ensures a secure seal with syringes, preventing leaks and sample loss.
One minor weakness is that the filters require pre-wetting with certain solvents to achieve optimal flow rates. The wetting requirement does add a slight step to the filtration process. Overall, the Whatman Anotop 10 filters meet and often exceed expectations for performance and reliability.
Design & Ergonomics
The Whatman Anotop 10 features a functional and ergonomic design. The polypropylene housing is lightweight and easy to grip. The luer lock fittings ensure a secure and leak-proof connection with standard syringes.
The hexagonal shape of the housing provides a comfortable grip, preventing slippage during filtration. The filters present no learning curve and are simple to use. The filters are designed with simplicity in mind.
Durability & Maintenance
The Whatman Anotop 10 filters are designed for single-use applications, so there is no cleaning or maintenance required. The robust construction of the polypropylene housing and Anopore membrane ensures durability throughout the filtration process. The filter integrity is maintained through even viscous filtering processes.
While not designed for extended use, the filters exhibit excellent resistance to chemical degradation and mechanical stress under normal operating conditions. They are not repairable but their single-use design eliminates the risk of cross-contamination. The single use design provides better testing results as well.
Accessories and Customization Options
The Whatman Anotop 10 and Anotop 25 Disposable Syringe Filters, Whatman 6809-1002 Anotop 10, Pack of 50 do not include any accessories beyond the filters themselves. The lack of included accessories simplifies the setup. However, they are compatible with standard luer lock syringes from various manufacturers.
There are no specific customization options for the Anotop 10 filters. However, users can select different pore sizes or membrane materials depending on their specific needs. Choosing the right filter is key.
