May 16, 2022 · The solvent flux is expected to improve with operating pressure. The CNIM showed better water separation efficiency than unmodified PTFE and PVDF membranes at all ∆P. At 10 psig, the water separation efficiency for the 0.1 µm PTFE membrane was 83% (Figure 4a), whereas 99.97% separation efficiency was observed for CNIM-3. Likewise, 0.22 µm
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. Prefiltration to improve filter performance can also be accomplished by the use of glass fiber prefilters that can be purchased separately.
Pall non-sterile syringe filters with PTFE membrane are ideal for use in the filtration of gas or organic solvents. PTFE syringe filters have been widely used for the sample preparation applications, removing particulate contamination and protecting HPLC systems and columns.

Foxx Life Sciences. EZFlow 25mm, 47mm, and 90mm membrane disc filters are used to retain particles or microorganisms by surface capture. The membrane disc filters are available in 0.22µm or 0.45µm pore sizes. The Hydrophobic PTFE membrane is bonded to a polypropylene support and due to its extreme chemical.
Jul 11, 2013 · Depending on the procedure performed, the membrane color or surface pattern may be important. 4. Also consider hydrophilic or hydrophobic membranes, temperature, flow rate, throughput, and sterilization needs. Types of Membrane Materials. Cellulose Nitrate (CN) membrane is the most popular membrane used in analytical and laboratory filtration
Pall’s Acrodisc One PSF Syringe Filters with wwPTFE membranes have been designed to protect analytical instrumentation and improve the reliability of results. wwPTFE membrane devices are chemically compatible with a wide variety of common solvents and are suitable for use in both aqueous and organic applications.
Feb 17, 2020 · PTFE Hydrophilic Syringe Filters 0.2 or 0.45um Resisting nearly all corrosive chemicals makes PTFE syringe filters an ideal choice. However, natural hydrophobic PTFE has it’s disadvantages not letting aqueous solutions passing through while many of these chemicals are diluted with water.
PTFE as a membrane for syringe filters is considered to be more “chemically resistant” and Nylon to be the most “extractable free” for HPLC or dissolution testing. The simple explanation of the differences is that chemical resistance is defined as the durability of the membrane to withstand some harsh solvents (normally not used in HPLC
membrane (1500–2000 PSI). The hydrophilic PTFE membrane retained particles quantitatively; no increase in backpressure was observed as expected. Chemical Compatibility Another key characteristic of membranes and syringe filter devices is their chemical compatibility. Of the housing materials used for syringe filters, high density
Target2 Syringe Filters are an ideal choice for general purpose laboratory use. Robust and reliable, they deliver excellent performance at an attractive price. Outstanding Performance Low extractable membranes and housings ensure that no filter-borne contaminants are added to your sample Performance-tested under actual HPLC conditions
PTFE is an ideal membrane for transducer protectors, since it blocks water vapor and is also ideal for filtering and de-gassing chromatography solvents. PTFE can be treated to be hydrophilic for applications where it is deemed necessary. View PTFE Membrane Filters View Hydrophilic PTFE Membrane Filters View PTFE Syringe Filters
PTFE Syringe Filters vs. Membrane Filters In considering the proper type of filter within the category of PTFE, it is essential likewise to consider both syringe filters and membrane filters. Each can provide the quality features and abilities required for any form of sampling and testing.
