solvent compatibility ptfe 0.2 micron filter for sterilization

The filter is ideal for filtration of solvents in sterile API manufacture, fermenter inlet air and exhaust venting, sterile process air, and sterile venting of tanks and autoclaves. The filters have a 0.2 micron PTFE membrane validated for absolute bacterial retention with the challenge data correlated to water intrusion testing.

These hydrophilic filters feature high-dirt loading capacity, and excellent compatibility with organic solvents and acids. They are typically utilized in applications such as, the filtration of cell media seperations prior to sterilization, clarification of dirt particulate-laden samples, and to pre-filter viscous serum and tissue media prior

Minisart® SRP15 Syringe Filter 17573-----K, 0.2 µm hydrophobic PTFE Minisart ® SRP with chemically inert hydrophobic PTFE is suitable for venting as well as harsh solvents with a pH of 1 - 14. Type 17573 with a pore size of 0.2 µm can be used for sample preparation and sterile filtration.

RC also has a broad solvent compatibility. Together with PTFE, RC is a useful general-purpose option to have on-hand. Extractables are a common symptom of membrane-sample incompatibility and affect sensitive downstream analytical techniques, such as ultra-high-performance liquid chromatography (UHPLC) and high-performance liquid chromatography

Pore Size (0.2 and 0.45 µm) — The filter pore size is usually a personal preference of the chromatographer but relates to the column packing material. Since there are many different packing materials, a general guideline is that most customers find that the 0.45 µm filter meets their requirements, although chromatographers are increasingly

Chemical compatibility is a critical consideration when selecting the proper sample prep syringe filter for your application. This chart outlines the chemical compatibility of the most common syringe filters. The contact time was 24 hours at 20°C.

The 0.5 μm pore size is normally used. Air and gas sterilization make use of the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 μm and 0.5 μm. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes.

be performed using a 0.1 µm pore filter. Routine labora tory sterilization of most media, buffers, biological fluids and gases is usually done with 0.2 or 0.22 µm pore filter membranes. Clarification and prefiltration of solutions and solvents is best accomplished with 0.45 µm or larger filter membranes.

Aug 07, 2018 · Charting compatibility. Hopefully, this quick overview helps you identify the most appropriate membrane-solvent combination for your application. To compare between all the common membranes and solvents, review the chemical compatibility chart in our guide to laboratory membrane filtration principles and chemical compatibility.

Sterilizing Grade 0.2 Micron PTFE Membrane Filter Cartridge. SERENE Hydrophobic PTFE Sterilizing Grade 0.2um filter cartridges are highly retentive hydrophobic membrane designed for critical liquid and gas sterilization. Hydrophobic PTFE filter medium provides exceptionally high air flow rates at low differential pressures Naturally Hydrophobic Membrane also provides high assurance of filter integrity andlong life, during high temperature venting application and during repeated steaming.

Chemical Compatibility Guide FFKM (Perfluoro Rubber) Perfluoroelastomers show broad chemical resistance similar to PTFE as well as good heat resistance. They show low swelling with almost all media. Depending on the material the operating temperatures range between -25 °C/-13 °F and +240 °C/+464 °F Special types can be used

Chemical Compatibility. PES membranes were exposed to the following chemicals for 48 hours. If there was no significant change in the bubble point, strength or appearance of the membrane, it was judged compatible with the chemical. If the membrane dissolved, or otherwise lost its strength, or changed significantly in appearance, it was rated
