Breaking Down the Features of Pall MicroFunnel Disposable Filter Funnels, Sterile, Pall Life Sciences 4806, Pack of 50
Specifications
The Pall MicroFunnel Disposable Filter Funnels, Sterile, Pall Life Sciences 4806, Pack of 50 are designed with precision and efficiency in mind. The 100 mL capacity is clearly marked in increments of 10 mL, with the 100 mL mark encircling the entire funnel for enhanced visibility during sample volume adjustments. The 0.2 µm pore size of the integral membrane is crucial for applications requiring the removal of bacteria and other microorganisms.
The membrane type specified for this particular model is Supor White, Plain. This polyethersulfone membrane is known for its high flow rates and low protein binding characteristics, making it ideal for a wide range of aqueous solutions. The Maximum Vacuum rating of 635 mm Hg (25 in. Hg) ensures that the funnels can withstand standard laboratory vacuum pressures without issue.
The physical dimensions are also noteworthy for usability. The Dimensions (With Cover) for the 100 mL funnels are approximately 6.1 dia. x 7.6H cm (2¹³/₃₂ x 3″). These dimensions make them easy to handle and fit within standard laboratory setups. The fact that they are supplied completely assembled and Gamma irradiation sterilized is a testament to Pall Life Sciences’ commitment to providing ready-to-use sterile products. The ordering information specifies they are individually bagged, which is vital for maintaining sterility until the point of use.
Performance & Functionality
The Pall MicroFunnel Disposable Filter Funnels, Sterile, Pall Life Sciences 4806, Pack of 50 perform their intended function with exceptional fidelity. The primary job is to reliably filter samples under vacuum, and they excel at this. The Supor membrane allows for rapid filtration, significantly reducing sample processing time compared to slower membrane types.
A key strength is the integral membrane seal, which ensures that all liquid passes through the membrane without bypassing it. The squeeze separation of cylinder from base mechanism is a brilliant design feature that allows for easy and clean removal of the filtered sample or the membrane itself for further analysis. A potential weakness, though minor, could be the 100 mL capacity for very large volume samples, but this is addressed by other models in the Pall MicroFunnel line. For standard microbial testing, it meets and often exceeds expectations for speed and reliability.
Design & Ergonomics
The design of the Pall MicroFunnel Disposable Filter Funnels, Sterile, Pall Life Sciences 4806, Pack of 50 prioritizes user-friendliness and contamination control. The materials used feel robust and chemically resistant, as expected from Pall Life Sciences. The funnel body has a pleasing heft without being overly heavy, contributing to a stable feel when handling.
The markings on the funnel are clear and easy to read, even with gloves on. The ergonomic design of the base allows for a comfortable grip when performing the “squeeze separation.” There is virtually no learning curve; the product is intuitive and ready to use straight out of the sterile packaging.
Durability & Maintenance
As a disposable product, the concept of “durability” in terms of longevity is different. These funnels are designed for single use, and their integrity is maintained throughout that one use. They will last as long as the filtration process requires, without showing any signs of wear or compromise during that time.
Maintenance is, by design, zero. This is one of their most significant advantages. The absence of a cleaning and sterilization cycle drastically reduces the risk of laboratory error and frees up valuable time for other critical tasks.
Accessories and Customization Options
The Pall MicroFunnel Disposable Filter Funnels, Sterile, Pall Life Sciences 4806, Pack of 50 are supplied as a complete, assembled unit. The primary “accessory” that comes with each funnel is its integral membrane, specifically the Supor White, Plain membrane with a 0.2 µm pore size in this iteration. While the product itself is not designed for customization in the way that, say, a firearm might be, Pall Life Sciences offers variations within the MicroFunnel product line.
These variations include different membrane types (like GN-6 mixed cellulose ester or Metricel* black modified polyethersulfone) and capacities (e.g., 300 mL funnels). This allows users to select the precise configuration needed for their specific application, offering a form of “customization” by choice of model. The product is designed to be compatible with standard vacuum filtration apparatus commonly found in laboratories.
