Mar 01, 2021 · In particular, we compared the main properties of the PVDF/PSF membranes with the PVDF/PTFE membranes (previous work). The biggest mean pore size, porosity, and pure water flux of the PVDF/PTFE membranes were 0.317 μm, 42.6% and 99.2 L/m 2 h, respectively .
Graver Technologies designs, engineers, and manufactures an extensive line of filter cartridges and housings to provide high performance and cost-effective solutions for a wide array of applications in the food and beverage, chemical, microelectronics, and healthcare markets. The liquid process filters are available with a wide range of media formats including melt blown depth filters, resin
Feb 15, 2022 · Dec 21, 2021 · Filter cartridges are used for membrane filtration of plasma fraction, vaccines, MAB, diagnostics, purified protein solutions, biological fluids, and solutions containing preservatives. Filters are constructed of PTFE and CTFE, and inner designs of in-line filter cartridges ensure the equal distribution of the solvent to the screen.
Oct 20, 2012 · Hydrophilic PTFE-reinforced Nafion membranes were prepared by the following procedure. 12 g of Nafion resin (Ion Power, 5 wt% EW Nafion in a solvent mixture) was dried at 60°C for 12 hours to obtain 0.6 g of Nafion. 12 g of co-solvents (N-Methyl-2-pyrrolidone (NMP):Methanol (MeOH), 2.5:7.5) were added to the dried Nafion resin and the solution was stirred for 4 hours at room temperature.
Robust and reliable spring return mechanical diaphragm pump. The double-layer PTFE membrane grants a high chemical compatibility, the pump body is made of aluminum and coated through a cataphoresis process to increases resistance to chemical and atmospheric agents. These features, combined with a great dosing accuracy and very low maintenance
The enhanced PTFE membrane offers exceptionally high liquid flow rates at low pressure differentials making Fluorofil™ F100 cartridges ideally suited to solvent filtration. For solvent and aggressive chemical filtration applications, Fluorofil™ F100 cartridges offer a wide range of chemical compatibility with high thermal stability.

PTFE is the most versatile plastic in terms of chemical compatibility Highly resistant to most acids, alcohols, detergents and solvents Ideal for use with reactive and corrosive chemicals The melting point of PTFE 1 is 600°K (327°C / 620°F)
PTFE is the 'ultimate' regular fiber as it has outstanding chemical and thermal resistance, with the right chemistry, it will operate up to 250°C. Two forms of the fiber are used in filtration applications: Brown - which is very much like a traditional textile fiber in appearance was the original PTFE fiber sold as Teflon.
Teflon (PTFE) Membrane. Highly resistant to chemical and thermal extremes, Teflon is an ideal membrane for use in filtration of aggressive chemicals, extreme operating temperatures and where critical filtration is required. Available micron pore sizes 0.03, 0.05, 0.1, 0.2, 0.45, and 1.0. Nylon Membrane. Broad chemical compatibility.
Memtrex FE (MFE) filters (Figure 1), with absolute rated PTFE membranes offer broad chemical compatibility with minimal extractables in a wide range of fluids and applications. The inherently hydrophobic PTFE membrane is ideally suited for the filtration of compressed air and other process gases.

The primary concern when choosing a solvent filter is solvent compatibility with the filter material. We offer several filters to accommodate the various types of HPLC solvents. Our wwPTFE (water wettable polytetrafluoroethylene) membrane is a universal solvent membrane to reduce confusion with filter selection. Typical membrane filters range
Chemical Compatibility Reference Chart Teflon® PTFE Teflon®* PTFE Chemical Compatibility Chart: Check the chemical compatibility of Teflon® and PTFE with various chemicals, solvents, alcohols and other products. Polytetrafluoroethylene (PTFE) is very non-reactive and is often used in containers holding reactive and corrosive chemicals.
