Membranes such as PES, nylon, PTFE, PVDF, PP and track-etched polycarbonate and polyester are available. Whatman also manufacturers other unique filtration medias such as cellulose paper, regenerated cellulose membrane, nitrocellulose membrane, cellulose acetate membrane, mixed cellulose ester membrane and Anopore® ceramic membrane. Meltblown polypropylene and glass microfiber filters offer versatility with high flow and high particulate loading. Precision woven screens are also available for coarse particulate removal. Choose your filter material from our extensive range of media options from leading manufacturers around the world, including Whatman manufactured filtration materials. Glass Microfiber (GMF) High bacteriological efficiency filter with excellent flow rates; very effective prefilter GMF has exceptional filtration characteristics. Structures produced from GMF combine high bacteriological efficiency (typically 99.999%) with low resistance to air flow and high particle loading capacity. This media is available in a range of filtration efficiencies including HEPA (which retains 99.97% of particles > 0.3 µm) and ULPA (which retains 99.9% of particles > 0.1 µm). GMF can be treated to make it hydrophobic or oleophobic. Non-Woven Polypropylene (NWPP) Ideal for heavy duty fine filtration Meltblown polypropylene is known for its durability and high dirt holding capacity. It has extremely high permeability for a given retention and is very versatile. Polypropylene is essentially inert and resistant to many chemicals, even at elevated temperatures. These properties make it suitable for the filtration of most liquids. Polytetraflouroethylene (PTFE) Hydrophobic microporous expanded PTFE membrane. Aggressive chemical and air/gas stream filtration PTFE is the most inherently hydrophobic microporous membrane available today. This durable media has a wide operating temperature range and resistance to the destructive effects of many chemicals. This media is widely used in venting applications. Woven Media/ Screen Precise coarse particulate removal Polyester and polypropylene screens are available. Woven media/screen provides a long service life and high resistance to physical and/or chemical damage. Precise mesh openings make this media an ideal filter for coarse particulate removal from blood or ink. Woven media/screen is extremely clean and non-shedding. Polyethersulfone (PES) Aqueous solution filtration for pharmaceutical and biological applications PES has very low protein binding characteristics, high liquid flow rates and throughput (long life) and low extractables. Polyethersulfone’s hydrophilic characteristics allow it to be used with both liquids and dry gases, making it suitable for a variety of environments. PES will withstand autoclaving. PES is the membrane of choice for many clinical applications.

Choosing the filtration solution that specifically addresses your unique product development and application needs can be an extremely complex process. A host of factors related to performance, chemical properties and configuration ultimately determine which filter options are right for you. This section provides a brief overview of filtration design, purpose and functionality. For in-depth, expert consultation on filtration evaluation and selection, please contact your Whatman representative. • Filter media: Although there are numerous types of filter media, those most commonly used are described below. As a broad classification, there are two trapping mechanisms: (1) membranes and woven media rely on surface retention, whereby the pore/mesh size determines the capture capabilities; and (2) depth filters trap particles within their layered matrix. • Hydrophilic vs hydrophobic: Hydrophilic media attracts water and can be wetted; hydrophobic repels water and can only be wetted with low-surface tension liquids, making it ideal for gas filtration and venting applications. • Pore size: Ratings refer to the size of a specific particle or organism retained by the filter media to a specific degree of efficiency. Nominal pore ratings refer to the media’s ability to retain the majority of the particulates at the rated pore size and larger. Absolute pore size ratings indicate the pore size at which a challenge organism of a particular size will be retained with 100% efficiency under defined test conditions. • Extractables: The contaminants that elute from the filter media and may adversely affect effluent quality. Extractables may include wetting agents in the filter media, manufacturing debris, sterilization residue or adhesives. • Flow rate and throughput: Viscosity determines a liquid’s resistance to flow. The higher a liquid’s viscosity, the lower the flow rate and the higher the differential pressure required to achieve a given flow rate. • Porosity: Porosity is the measure of all pores in a membrane; more pores yield higher flow rates. QUESTIONS TO CONSIDER WHEN DESIGNING YOUR FILTER: • Application: What is the function of the filter? • Compatibility: What solution (liquid or gas) will be filtered? • Volume: How much will be filtered, and for how long? • What flow rate is necessary? At what DP (Differential Pressure)? • What retention value is necessary (Absolute/Nominal)? • What connectors are ideal for the product? • Size constraints? • Filter media preference? • Does the filter need to be hydrophilic or hydrophobic? • Temperature requirements? • Sterilization: Does the product need to be sterile? If so, by what method? • Is the product a medical device? • Does the product need to be reusable or disposable? • Special packaging required?
