Real-World Testing: Putting Whatman Puradisc Syringe Filters, Whatman 6779-1302 13 Mm Syringe Filters, Pack of 100 to the Test

First Use Experience

My initial testing ground for the Whatman Puradisc Syringe Filters, Whatman 6779-1302 13 Mm Syringe Filters, Pack of 100 was in filtering environmental water samples collected from a local river. These samples contained a high concentration of suspended solids, algae, and other organic matter. I needed to remove these contaminants before analyzing the water for heavy metal content using ICP-MS.

The filters performed admirably, even with the heavily contaminated samples. The 0.2 µm pore size effectively removed particulate matter, resulting in a visibly clearer filtrate. Using a standard 10 mL syringe, the filtration process was smooth and consistent, with no noticeable pressure build-up or membrane rupture.

The Whatman Puradisc Syringe Filters, Whatman 6779-1302 13 Mm Syringe Filters, Pack of 100 proved incredibly easy to use. The luer-lock connection provided a secure and leak-free attachment to the syringe, and the compact 13 mm diameter allowed for easy handling. No specialized training was required, making it accessible to both experienced and novice lab technicians.

After filtering approximately 20 samples, I noticed a slight decrease in flow rate with some filters, likely due to particulate clogging. However, this was easily remedied by using a fresh filter for each set of 5-10 samples, depending on the contamination level. Overall, I was pleasantly surprised by the filters’ robustness and consistent performance.

Extended Use & Reliability

After several months of regular use, the Whatman Puradisc Syringe Filters, Whatman 6779-1302 13 Mm Syringe Filters, Pack of 100 have proven to be a reliable workhorse in my lab. I have used them for filtering a wide range of samples, including aqueous solutions, organic solvents, and biological buffers. The PVDF membrane has shown excellent chemical resistance, with no signs of degradation or swelling.

The filters have demonstrated consistent durability, with no instances of housing cracking or membrane detachment. The polypropylene housing has withstood repeated use and handling without any signs of wear and tear. I’ve even accidentally dropped a few without causing any damage, a testament to their solid construction.

Maintenance is straightforward, requiring only occasional rinsing with distilled water between samples. Since the filters are not sterile, autoclaving is not an option. However, for non-critical applications, a quick flush with ethanol is sufficient to remove residual contaminants.

Compared to my previous experiences with other filter brands, the Whatman Puradisc Syringe Filters, Whatman 6779-1302 13 Mm Syringe Filters, Pack of 100 consistently outperform in terms of flow rate, chemical compatibility, and overall reliability. The price point also makes them a more attractive option for high-throughput applications. They have significantly improved the efficiency and accuracy of my lab work.

Breaking Down the Features of Whatman Puradisc Syringe Filters, Whatman 6779-1302 13 Mm Syringe Filters, Pack of 100

Specifications

• Filter Media: PVDF – The Polyvinylidene Fluoride (PVDF) membrane offers broad chemical compatibility and low protein binding, making it suitable for a wide range of applications. This minimizes analyte loss due to adsorption and ensures accurate results.
• Pore Size: 0.2 µm – This pore size effectively removes bacteria and fine particulates, providing sterile or particle-free solutions. This is critical for cell culture, chromatography, and other sensitive applications.
• Sterility: Nonsterile – These filters are non-sterile and suitable for general filtration purposes where sterility is not a primary requirement. This lowers the cost compared to sterile filters, making them ideal for applications like sample prep for chemical analysis.
• Whatman No.: 6779-1302 – This is the specific product code for easy identification and ordering. This ensures you are getting the exact filter with the desired specifications.
• Unit: Pack of 100 – Each pack contains 100 individual filters, providing a convenient and cost-effective supply for laboratory use. This reduces the need for frequent reordering and ensures consistent availability.
