Breaking Down the Features of Whatman Polycap TC Filters, Whatman 6715-3601 Polycap 36 With Bell

Specifications

• Connection: The Whatman Polycap TC Filters, Whatman 6715-3601 Polycap 36 With Bell features a 6–10 mm (¹/4–³/8“) SB (stepped barb) connection, providing versatile compatibility with various tubing sizes. This connection ensures a secure and leak-proof attachment, which minimizes the risk of contamination.
• Pre/Final Pore Size, µm: The filter incorporates a dual-layer membrane with a pre-filter pore size of 0.2µm and a final filter pore size of 0.1µm. This dual-layer design maximizes filtration efficiency and ensures effective removal of microorganisms and particulates, providing sterile filtrate.
• Whatman No.: The specific model number for this filter is 6715-3601, which ensures accurate ordering and identification of the product. This number helps to distinguish this specific configuration from other Whatman filters with different pore sizes or connection types.
• Unit: The filters are sold individually (“Each”), allowing for flexible ordering based on specific needs. This unit-based sale is beneficial for laboratories that require precise quantities and want to avoid unnecessary bulk purchases.
• Sterile and Pyrogen-Free: This ensures that the filter is free from viable microorganisms and pyrogens (fever-inducing substances), making it suitable for applications where sterility and biocompatibility are critical. This eliminates the need for autoclaving or other sterilization methods, saving time and resources.
• Polyethersulfone (PES) Membrane: Constructed with two layers of PES membrane, the filter is inherently hydrophilic, low in extractables, and protein-binding. This makes it suitable for a wide range of biological samples, including protein solutions and cell culture media, minimizing the risk of sample loss or alteration.
• Effective Filtration Area: The Polycap 36 filters have an effective filtration area of 550cm². This large surface area ensures high flow rates and efficient filtration, reducing processing time and maximizing throughput.
• Positive Pressure Filtration: Designed for positive pressure filtration, the filter minimizes protein denaturation. This makes it ideal for filtering sensitive biological solutions where maintaining protein integrity is essential.
