Real-World Testing: Putting Whatman Filter Funnels, Three-Piece, Whatman 1950-009 to the Test

First Use Experience

My first field test of the Whatman Filter Funnels, Three-Piece, Whatman 1950-009 took place on the banks of a rushing mountain stream, filtering sediment from water samples collected for heavy metal analysis. The setup was straightforward, and the three-piece design made assembling and disassembling the funnel quick and easy, even while wearing gloves.

The conditions were damp and chilly, typical of alpine environments, but the plastic-coated clamps provided a secure grip, preventing any leaks during the filtration process. The ease of use was remarkable, allowing us to process a large number of samples efficiently despite the challenging environment; the large 200mL volume was also a definite plus.

After the first use, I noticed a small amount of sediment trapped in the ground contact flanges of the glass pieces; however, it was easily cleaned with a brush and distilled water. Overall, the initial experience was positive and significantly better than past experiences using less robust filtration methods.

Extended Use & Reliability

After several weeks of continuous use in the field, the Whatman Filter Funnels, Three-Piece, Whatman 1950-009 have proven to be remarkably reliable and durable. Despite being subjected to rough handling during transport and repeated exposure to harsh weather conditions, the glass components have shown no signs of cracking or chipping.

Cleaning the funnel after each use has been relatively simple, with most contaminants easily removed using standard laboratory detergents and a soft brush. The borosilicate glass has resisted staining and etching, maintaining its clarity and transparency.

Compared to the disposable plastic funnels I previously used, the Whatman offers superior performance and durability, significantly reducing the risk of contamination and ensuring more consistent results. The investment in quality has undoubtedly paid off in terms of improved data accuracy and reduced downtime.
