The Whatman Mini-UniPrep Syringeless Filters, Whatman UN203NPUDPP Filters With Standard Cap, Pack of 100 performed flawlessly even in slightly damp outdoor conditions. The all-in-one design allowed for single-handed operation, which was a huge benefit in the field. The dp polypropylene membrane provided excellent flow rates, even with particulate-laden samples.
Using the Whatman Mini-UniPrep filters was incredibly straightforward. Simply draw the sample into the outer chamber, place the assembly into a vial, and press the plunger to force the filtrate through the membrane. The process was intuitive and required no prior experience. There were no initial problems.
Extended Use & Reliability
After several weeks of daily use, the Whatman Mini-UniPrep filters continued to perform reliably. We processed hundreds of samples, and the filters consistently provided clean, particle-free filtrates. The filter integrity remained excellent, with no observed instances of membrane rupture or leakage.
The dp polypropylene housing showed no signs of cracking or discoloration, even after repeated exposure to various solvents and chemicals. The filters were incredibly robust. The filter required virtually no maintenance, besides proper disposal.
Compared to our previous method of using separate syringes and filters, the Whatman Mini-UniPrep system represented a significant improvement in both efficiency and ease of use. The Whatman Mini-UniPrep Syringeless Filters, Whatman UN203NPUDPP Filters With Standard Cap, Pack of 100 outperformed our previous system in terms of speed, convenience, and reduced risk of contamination.
Breaking Down the Features of Whatman Mini-UniPrep Syringeless Filters, Whatman UN203NPUDPP Filters With Standard Cap, Pack of 100
Specifications
- Membrane: dp Polypropylene. This membrane is ideal for general filtration media and solvent-based samples, offering good chemical compatibility and flow rates.
- Pore Size: 0.45 µm. The 0.45 µm pore size effectively removes particulate matter, ensuring sample clarity for HPLC analysis and other sensitive applications.
- Whatman No.: UN203NPUDPP. This is the unique identifier for this specific product configuration.
- Unit: Pack of 100. Each pack contains 100 individual filters, providing a cost-effective solution for high-throughput laboratories.
- Filtering Capacity: 0.5 mL. Each filter can process up to 0.5 mL of sample, suitable for typical HPLC sample volumes.
- Maximum Operating Temperature: 50°C (120°F). The filter can withstand temperatures up to 50°C without compromising its integrity or performance.
These specifications are crucial because they directly impact the filter’s ability to effectively remove particulate matter without altering the sample’s composition. The dp polypropylene membrane’s chemical compatibility and flow rate, combined with the 0.45 µm pore size, guarantee the sample’s cleanliness and purity. The high unit count and filtering capacity further enhance the filter’s utility.
