I needed a reliable, portable solution for phase separation in remote locations, where access to sophisticated lab equipment is limited.
Upon receiving the package, the paper felt robust, exhibiting a unique texture. Its substantial feel hinted at durability, a crucial factor for field applications where handling can be rough. I compared it to standard filter paper and solvent-resistant membranes; its water-repellent nature stood out immediately, offering a unique advantage for my specific needs.
My first impression was one of cautious optimism. The description promised effective phase separation, but real-world performance is always the ultimate test. I was eager to see how it would handle the challenges of field conditions compared to other methods.
Real-World Testing: Putting Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-125, Pack of 100 to the Test
First Use Experience
I tested the Whatman No. 1 PS Water Repellent Phase Separating Paper during a water quality assessment project in a remote backcountry area. Water samples were collected from various streams and ponds, with the goal of identifying potential sources of contamination. The paper was used to separate organic contaminants like oil and pesticides from the water.
The paper performed remarkably well even in humid and occasionally rainy conditions. Its water-repellent nature allowed for quick and clean separation without the paper becoming saturated or disintegrating. It did take a few initial uses to get accustomed to the optimal folding technique for maximum surface area and efficient flow.
After the first few separations, I noticed that the organic phase collected cleanly on one side. There was no breakthrough of aqueous solution. This was a significant improvement over using separatory funnels, which are bulky and impractical for field use.
Extended Use & Reliability
After several weeks of consistent use, the Whatman No. 1 PS Water Repellent Phase Separating Paper maintained its performance. The paper showed no signs of degradation despite being exposed to various chemicals and handling conditions. Its consistent performance ensured reliable results throughout the study.
Minor discoloration occurred after repeated exposure to certain organic solvents. The paper’s structural integrity remained intact, which is paramount for consistent results. The occasional need to carefully peel the paper to recover the separated phase was a minor inconvenience.
Compared to previously used solvent extraction methods using separatory funnels, this paper significantly reduced both time and effort. The convenience of field use and consistent performance far outweighed the minor maintenance needs. This paper significantly simplified the water testing process, allowing for more efficient data collection.
Breaking Down the Features of Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-125, Pack of 100
Specifications
The Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-125, Pack of 100 features a 12.5 cm diameter, making it suitable for standard funnels. It is categorized under Whatman No. 2200-125, with a pack containing 100 sheets. The paper’s medium porosity allows for a medium flow rate.
Its particle retention is rated at 11 µm, allowing for the separation of relatively fine particles alongside phase separation. The unique combination of cotton muslin and cellulose provides both strength and water repellency. These specifications translate to efficient and reliable separations, crucial for accurate analysis.
Performance & Functionality
The Whatman No. 1 PS Water Repellent Phase Separating Paper excels in its primary function: separating aqueous and organic phases. Its water-repellent characteristic allows the organic phase to pass through while retaining the aqueous phase. This significantly reduces cross-contamination and improves the accuracy of subsequent analyses.
The main strength lies in its simplicity and portability for field use. A potential weakness is its single-use nature, generating waste. It consistently met my expectations for reliable phase separation, providing cleaner samples compared to less refined methods.
Design & Ergonomics
The paper’s circular design and 12.5cm diameter are standard for easy integration with funnels and laboratory setups. The feel of the paper is substantial, providing confidence during handling. Its pre-cut shape eliminates the need for cutting, simplifying the process.
The paper is relatively user-friendly, requiring minimal training. Optimizing the folding technique for specific volumes might require a brief learning curve. However, the overall design promotes efficient and effortless use.
Durability & Maintenance
The Whatman No. 1 PS Water Repellent Phase Separating Paper is designed for single-use applications. Its durability refers to its ability to withstand handling during the separation process. The risk of tearing is minimal as long as reasonable care is taken during folding and pouring.
Maintenance is not applicable as the paper is discarded after use. Proper disposal of used paper, especially after contact with hazardous chemicals, is essential. Storage should occur in a dry environment to maintain water repellency.
Accessories and Customization Options
The Whatman No. 1 PS Water Repellent Phase Separating Paper doesn’t require specific accessories for its primary function. However, using it in conjunction with a funnel of appropriate size (typically 100mm) is essential. Customization is limited to folding techniques to adjust the separation rate.
The paper is compatible with standard laboratory funnels and glassware. It works effectively with a variety of organic solvents. There are no specific modifications recommended as the paper is designed for a specific purpose.
