Breaking Down the Features of Pall Magnetic Filter Funnels, 47 mm, Pall Life Sciences 4242
Specifications
The Pall Magnetic Filter Funnels, 47 mm, Pall Life Sciences 4242 boasts specifications that speak directly to its intended purpose: high-throughput, reliable laboratory filtration. Its 47 mm filter membrane compatibility is a standard size, ensuring broad usability with a wide range of membrane filters. The total capacity of 300 mL is generous for most common vacuum filtration tasks, allowing for processing of moderate sample volumes in a single go.
The defining feature is undoubtedly the dual magnet seal. This innovative system eliminates the need for traditional clamps, providing a secure, no-leak connection between the funnel body and stem. This magnetic connection not only ensures integrity but also facilitates one-handed operation, a crucial ergonomic advantage in a busy lab setting.
Constructed from durable, chemical-resistant polyphenylsulfone, this funnel is built to withstand exposure to a variety of solvents and reagents, including common anti-foaming agents. The material choice is critical for longevity and preventing contamination. Furthermore, the funnel includes 50 mL graduations, offering a degree of accuracy for sample measurement directly within the funnel itself.
These specifications are not mere technical data points; they translate directly into practical benefits. The 47mm compatibility makes it versatile, the 300 mL capacity reduces the need for frequent re-filtration, and the magnetic seal fundamentally simplifies the process, minimizing potential user error. The chemical resistance and autoclavable nature ensure it can be used in diverse and demanding laboratory settings, including those requiring strict sterilization protocols.
Performance & Functionality
The Pall Magnetic Filter Funnels, 47 mm, Pall Life Sciences 4242 performs its core function of vacuum filtration with exceptional efficiency and reliability.
