Whatman PVDF GD/X Syringe Filters, Whatman 6872-2504, Pack of 150 Review

Let’s Dive into Whatman PVDF GD/X Syringe Filters, Whatman 6872-2504, Pack of 150

The Whatman PVDF GD/X Syringe Filters, Whatman 6872-2504, Pack of 150 represents a crucial piece of equipment for anyone working with lab samples requiring filtration. These filters are designed for both aqueous and organic-based solutions and boast a low protein binding polyvinylidene fluoride (PVDF) membrane. The inclusion of two prefilters – a multigrade GMF 150 (10:1µm) and a Grade GF/F (0.7µm) – distinguishes this filter from basic syringe filters, promising efficient filtration even with challenging samples.

My work often involves preparing samples from soil and water sources for sensitive analytical equipment. The challenge is that these samples are frequently loaded with particulate matter that can clog the instruments and degrade accuracy. I needed a reliable, high-throughput filtration solution that wouldn’t introduce contaminants or alter the sample composition, and that is why I turned to Whatman.

Upon unboxing the Whatman PVDF GD/X Syringe Filters, Whatman 6872-2504, Pack of 150, I was immediately struck by the sheer quantity – 150 filters inspire confidence. The filters themselves felt robust and well-constructed, with a clear indication of the pore size and filter type printed on each unit.

I considered several other syringe filters, including offerings from Millipore and Sartorius. Ultimately, the Whatman filters won out due to the integrated prefilters and the established reputation of Whatman for quality and reliability. I was also swayed by the promise of being able to filter “difficult” samples with minimal hand force, a key consideration for processing large batches.

My first impression was positive; I was eager to see if these filters would live up to the claims and streamline my sample preparation process. Given the price point of $799.99, I expected a high level of performance and consistency.

Real-World Testing: Putting Whatman PVDF GD/X Syringe Filters, Whatman 6872-2504, Pack of 150 to the Test

First Use Experience

My initial testing ground was my environmental lab, specifically focused on preparing water samples for pesticide residue analysis using liquid chromatography-mass spectrometry (LC-MS). I utilized the Whatman PVDF GD/X Syringe Filters, Whatman 6872-2504, Pack of 150 to filter samples collected from various agricultural sites. The conditions ranged from relatively clean well water to highly turbid surface water after rainfall.

The Whatman filters performed admirably under varying conditions. Even with the silty, particulate-laden surface water samples, the flow rate remained consistent, and I didn’t experience any clogging. I immediately noticed the reduced hand force required compared to the single-layer filters I had previously used; this was a significant advantage when processing dozens of samples.

The ease of use was immediately apparent; simply attach the filter to a syringe and gently push the sample through. There was a slight learning curve in determining the optimal pressure to apply, but after a few samples, it became second nature. The transparent housing also allowed for visual inspection of the filter, enabling me to gauge the level of particulate buildup.

The biggest surprise was the consistent flow rate even with heavily contaminated samples. This significantly reduced sample preparation time and minimized the risk of introducing errors.

Extended Use & Reliability

After several weeks of continuous use, the Whatman PVDF GD/X Syringe Filters, Whatman 6872-2504, Pack of 150 continued to deliver consistent and reliable performance. They became an indispensable part of my sample preparation workflow.

In terms of durability, the filters held up well. I didn’t experience any instances of filter rupture or leakage, even when applying moderate pressure to viscous samples. Routine maintenance was simple: discard the used filter after each sample.

Compared to my previous experiences with single-layer filters, the Whatman filters significantly outperformed them in terms of flow rate, capacity, and ease of use. They reduced the risk of clogging, minimized hand fatigue, and improved the overall efficiency of my lab work. The low protein binding characteristics also provided me confidence for biological assays.

Breaking Down the Features of Whatman PVDF GD/X Syringe Filters, Whatman 6872-2504, Pack of 150

Specifications

Here are the key specifications of the Whatman PVDF GD/X Syringe Filters, Whatman 6872-2504, Pack of 150:

• Pore Size: 0.45 µm: This pore size is ideal for removing bacteria and other particulate matter while allowing dissolved compounds to pass through, making it suitable for a wide range of analytical applications.
• Diameter: 25 mm: The larger diameter provides a greater surface area for filtration, increasing the flow rate and throughput, especially for larger sample volumes.
• Filter Membrane Material: Polyvinylidene Fluoride (PVDF): PVDF offers excellent chemical resistance and low protein binding, making it suitable for both aqueous and organic solvents and minimizing sample loss due to adsorption.
• Prefilters: Graded Density Multigrade GMF 150 (10:1 µm) and Grade GF/F (0.7 µm): These prefilters remove larger particulate matter, extending the lifespan of the main PVDF membrane and preventing clogging.
• Housing Material: Polypropylene: This material offers good chemical resistance and structural integrity, ensuring that the filter can withstand the pressures of syringe filtration.
• Whatman No.: 6872-2504: This is the unique product identifier for easy ordering and tracking.
• Unit: Pack of 150: The bulk packaging is convenient for labs with high-throughput filtration needs.

These specifications matter because they directly influence the performance, reliability, and suitability of the filters for specific applications. The pore size determines the size of particles that can be removed, while the membrane material affects the compatibility with different solvents and the potential for sample loss. The inclusion of prefilters greatly extends the life of the filter and reduces the necessary force.
