Breaking Down the Features of Pall MicroFunnel Disposable Filter Funnels, Sterile, Pall Life Sciences 4803, Pack of 50

Specifications

The Pall MicroFunnel Disposable Filter Funnels, Sterile, Pall Life Sciences 4803, Pack of 50 are engineered with a specific set of features designed to ensure efficient and sterile sample preparation. The key specification that defines its filtering capability is the 0.2 µm pore size of the integrated membrane. This pore size is crucial for retaining bacteria and particulate matter, making it ideal for microbiological analyses and the removal of fine suspended solids.

The membrane itself is a Supor* White, Gridded material, which is a polyethersulfone membrane. This type of membrane is known for its excellent flow rates and low protein binding, making it versatile for a wide range of aqueous solutions. The gridded surface provides a clear reference for colony counting if microbial analysis is the intended application. The 100mL capacity of the funnel is clearly marked in 10mL increments, offering practical volume measurement directly on the unit. This eliminates the need for separate graduated cylinders in many field applications.

The Pall No. 4803 identifies this specific configuration, and the units are supplied in a Pack of 50, individually bagged and gamma irradiation sterilized. This sterile delivery method is paramount for applications where microbial contamination must be avoided. The maximum vacuum rating of 635 mm Hg (25 in. Hg) ensures that the funnels can withstand standard laboratory vacuum levels without structural compromise, facilitating efficient filtration. The dimensions, approximately 6.1 dia. x 7.6H cm (with cover), make these funnels compact and easy to handle, even in confined laboratory spaces or field setups.

These specifications are not just technical data; they translate directly into practical benefits. The 0.2 µm pore size is the workhorse for ensuring that microorganisms are effectively captured, a critical step in water quality testing for pathogens or in pharmaceutical QC for sterility checks. The Supor* membrane‘s properties mean that sensitive downstream analyses, such as biochemical assays or molecular detection, are less likely to be compromised by the filter itself. The clear volume markings and individually sterile packaging directly address the primary concerns of accuracy, sterility, and convenience, which are vital for reliable scientific data.

Performance & Functionality

The core function of the Pall MicroFunnel Disposable Filter Funnels, Sterile, Pall Life Sciences 4803, Pack of 50 is to provide rapid, reliable, and sterile filtration of liquid samples.

The vacuum seal created when connected to a standard filtration apparatus is robust, preventing leaks and ensuring that the entire sample passes through the filter.

One of the standout strengths is the elimination of assembly and sterilization steps required with traditional filter funnels. This single-use nature dramatically reduces the risk of cross-contamination, a persistent concern in many testing environments. The gamma irradiation sterilization is a critical feature that provides a high level of assurance for aseptic procedures. The squeeze separation of the cylinder from the base is an ingenious design element that allows for quick and easy access to the filtered membrane. This is a significant advantage for rapid sample processing or for when the membrane needs to be preserved for direct analysis.

However, there are minor considerations. While excellent for aqueous samples, these funnels are not designed for filtering large volumes of viscous organic solvents, as the plastic and membrane material might not be compatible. The 100mL capacity is sufficient for many standard testing protocols, but for applications requiring filtration of significantly larger volumes, the 300mL variant would be necessary. The price point, while justified by the sterility and convenience, is higher than DIY filtration setups, which might be a consideration for high-throughput laboratories with very tight budgets. Despite these minor points, the Pall MicroFunnel overwhelmingly meets and often exceeds expectations for its intended applications.
