The process was significantly faster and more straightforward compared to traditional syringe filters and vials, especially with wet hands.
The ease of use was remarkable. Simply draw the sample into the unit, press the plunger, and the filtered sample is ready for analysis or storage. I didn’t need any special training or tools. There were no initial issues or surprises.
Extended Use & Reliability
After several weeks of continuous use in various field locations, the Whatman Mini-UniPrep Syringeless Filters, Whatman US203NPUPP Filters With Slit Septa Cap, Pack of 100 proved to be remarkably reliable. Even after being subjected to rugged handling during transport, each unit performed consistently without leakage or filter failure.
Durability was excellent, with no signs of physical degradation despite exposure to varying temperatures and moisture levels. The polypropylene housing remained intact, and the slit septa caps retained their sealing ability. Maintenance was practically non-existent, which is a huge benefit in the field.
Compared to my previous experiences with multi-step filtration setups, these filters were a clear winner. They significantly reduced the risk of contamination, minimized sample handling time, and maintained consistent filtration performance across various environmental conditions. They far outperformed my expectations.
