Going All In on the Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-110, Pack of 100
In the meticulous world of laboratory science, efficiency and accuracy are paramount. My search for a reliable phase separation method led me to the Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-110, Pack of 100. This specialized paper promised to streamline the process of separating immiscible liquid phases, a common bottleneck in many experimental procedures. Prior to this, my lab relied on traditional separatory funnels, which, while effective, often consumed valuable time and bench space. The prospect of a faster, more integrated solution was compelling.
Upon first glance, the packaging itself exuded a sense of professional quality. The paper discs were neatly arranged within their protective container, hinting at careful manufacturing. There was no immediate sense of ‘wow’ factor, but rather a quiet confidence in its intended purpose. I had considered generic laboratory filter papers, but the specific “phase separating” designation and the silicone impregnation were key differentiators. A sense of pragmatic optimism settled in; this seemed like a tool designed to solve a specific, recurring challenge.
Real-World Testing: Putting Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-110, Pack of 100 to the Test
First Use Experience
My initial tests with this phase separating paper were conducted on my primary lab bench, amidst ongoing organic synthesis projects. The scenario involved separating an organic solvent layer from an aqueous layer, a routine yet critical step. I placed a pre-wetted disc into a funnel, introduced the mixed liquid, and observed.
Performance was remarkably swift; the paper readily allowed the hydrophobic organic phase to pass through while effectively retaining the hydrophilic aqueous phase. It was intuitive from the outset; the process mirrored gravity filtration but with the added benefit of selective phase retention. One slight surprise was the speed at which the separation occurred, often faster than I could have anticipated, requiring me to have a receiving flask ready.
Extended Use & Reliability
After several weeks of consistent use, the Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-110 has proven its worth. It has become an integral part of my workflow for routine extractions and washes.
Durability has been excellent. Even after repeated wetting and drying cycles (albeit within the same experimental run), the paper maintained its integrity, showing no signs of tearing or delamination. It holds up well to common laboratory solvents and mild acids/bases. Maintenance is virtually non-existent, as these are disposable units, making post-experiment cleanup incredibly straightforward. Compared to the extensive washing and drying required for separatory funnels, this is a significant time saver.
Breaking Down the Features of Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-110, Pack of 100
Specifications
The Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-110 comes in a Pack of 100 discs, each with a 11.0 cm diameter. This size is well-suited for standard laboratory funnels, offering ample surface area for effective separation. The paper is designated as Whatman No. 2200-110, a specific identifier for this product.
It features a Medium porosity and a Medium flow rate, balancing efficient passage of the desired phase with effective retention of the other. The Particle Retention is listed at 11 µm, indicating its capability to filter out fine particulates that might otherwise contaminate the separated layers. The silicone impregnation is the critical feature, rendering it water-repellent and thus enabling its phase-separating function by selectively interacting with different polarities.
Performance & Functionality
The primary job of this phase separating paper is to rapidly and cleanly separate immiscible liquid phases, and it excels at this task. The water-repellent treatment ensures that aqueous solutions are retained, while organic solvents pass through with remarkable efficiency. This significantly speeds up extraction and washing steps in synthetic chemistry and analytical procedures.
A key strength is its speed and simplicity; it often outperforms traditional separatory funnels for routine separations. The main weakness, if one could call it that, is its disposability. While this enhances convenience, it means it’s not suitable for applications where material reuse is essential or where waste generation needs to be minimized for environmental or cost reasons. For its intended purpose, however, it meets and often exceeds expectations.
Design & Ergonomics
The design of the Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-110 is inherently simple: a circular filter paper disc. The material feels robust enough to handle the forces involved in liquid filtration without premature failure. The silicone impregnation is evenly applied, providing a consistent hydrophobic surface across each disc.
Ergonomically, it’s designed to fit standard lab funnels, making it incredibly easy to use. There’s no steep learning curve; any lab technician or researcher familiar with basic filtration will find it intuitive. The pre-cut 11.0 cm diameter is a thoughtful touch, minimizing the need for manual cutting and ensuring consistent performance.
Durability & Maintenance
As a disposable product, the concept of long-term durability in the traditional sense doesn’t apply. However, its in-use durability is excellent for a single application. It consistently performs its separation duty without degrading during the process.
Maintenance is essentially zero, as each disc is used and then discarded. This eliminates the tedious cleaning and drying routines associated with glassware like separatory funnels. Care should be taken, however, to ensure the paper is properly seated in the funnel to prevent bypass of the liquid phases.
Accessories and Customization Options
The Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-110 comes as a standalone product, a Pack of 100 units. There are no specific accessories bundled with this item.
Customization options are also limited to its intended use. While one could theoretically cut the discs to different sizes, this would likely compromise the integrity and performance of the water-repellent treatment and the overall separation capability. It’s designed to be used as is, fitting into standard laboratory funnels.

Who Should Buy Whatman No. 1 PS Water Repellent Phase Separating Paper, Whatman 2200-110, Pack of 100?
This specialized paper is ideal for organic chemists, analytical chemists, and any laboratory professional regularly performing liquid-liquid extractions or washes. Researchers involved in process development or scale-up where speed and consistency are critical will find it particularly beneficial. It’s also a great tool for teaching labs, simplifying a common procedure for students.
Those who should probably skip this product are individuals or labs prioritizing zero-waste protocols or those needing to perform separations that require extremely high purity without any potential for trace leaching from the paper. It is also not a substitute for specialized filtration needs beyond phase separation. For those performing very large-scale industrial separations, traditional separatory funnels or continuous extractors might be more cost-effective.
A crucial complementary item would be a standard laboratory funnel and appropriate collection flasks. Ensuring you have a secure way to hold the funnel and manage the flow of liquids will maximize the effectiveness of the phase separating paper.
