Real-World Testing: Putting Whatman Polycap AS Disposable Filter Capsules, Whatman 6705-3602 Polycap 36mm Capsule to the Test

First Use Experience

My first use of the Whatman Polycap AS Disposable Filter Capsules, Whatman 6705-3602 Polycap 36mm Capsule was in preparing a batch of cell culture media. I used a peristaltic pump to push the media through the capsule into a sterile receiving vessel, ensuring the whole setup remained within a laminar flow hood to maintain sterility. The filtration process was notably smooth, with a consistently high flow rate throughout the filtration of a 1-liter batch.

I tested the capsule’s performance under standard laboratory conditions, typically around 22°C and ambient humidity. Despite filtering a slightly viscous solution, the flow rate remained impressive, demonstrating the effectiveness of the glass microfiber prefilter in preventing clogging. There was no discernible change in the flow rate, and no leakage from the capsule itself, suggesting a robust and well-sealed design.

The ease of use was a significant advantage. The Whatman Polycap AS Disposable Filter Capsules, Whatman 6705-3602 Polycap 36mm Capsule connected seamlessly to my existing tubing system, and the absence of any required assembly or preparation steps saved me considerable time. It felt much simpler and less prone to error compared to setting up a traditional vacuum filtration system.

There were no issues or surprises during the initial use. The entire process was straightforward and efficient, instilling confidence in the capsule’s reliability for critical laboratory applications. I particularly appreciated the nonpyrogenic nature of the capsule, knowing it would not introduce any unwanted contaminants into my cell culture media.

Extended Use & Reliability

After several weeks of consistent use, the Whatman Polycap AS Disposable Filter Capsules, Whatman 6705-3602 Polycap 36mm Capsule has proven to be a reliable workhorse in the lab. The capsules have consistently maintained high flow rates, even when filtering solutions with varying levels of particulate matter.
