Hydrophilic PTFE membranes are unsupported membrane that ideal for HPLC and mixtures of aqueous and organic solvents. Use with both aqueous and organic solvents, along with their mixtures.
PTFE pleated filter cartridge Main Features: 1. Inherently hydrophobic more resistant to water intrision than commonly used PVDF membrane. 2. Withstand shocks, back pressures and repeated sterilizations. 3. 100% bacterial retention and effective filtration to 0
Nylon 66 filter is compatible with aqueous and alcoholic solvents and most widely used in the chemical industry. Nylon membrane, made by a special process. While ensuring the strength of the filter membrane, the non-woven support layer is removed, and it has a higher flow rate.

2018/8/7 · DO USE: for filtering solvents and other aggressive chemicals, such as acetone and DMSO. MAYBE USE: when you need to filter aqueous solutions and sodium hydroxide. You’ll need to pre-wet with a water-miscible solvent, such as methanol, to overcome the hydrophobicity of the membrane.
A method for producing a microporous membrane, wherein the heat of fusion of the modified polytetrafluoroethylene is less than 32 J / g, and the stretching step comprises a low-temperature stretching step and a high-temperature stretching step, and the
Donaldson Membranes has a portfolio of Tetratex fabrics, involving expanded micro-porous PTFE (ePTFE) membranes, films and laminates, the membrane being stable from –270 to +260 C. Other such membranes are based on micro-porous polyurethane (e.g. Aquatex, produced by Porvair) or on micro-porous polyvinylidene fluoride (PVDF) cast directly onto the fabric.
The hydrophobic PTFE membrane is ideally suited for filtering acids, bases and solvents. In addition, the hydrophobic membrane provides superior flow and pressure drop characteristics per unit area for gas filtration and tank venting applications, fermentation feed air.
PTFE Syringe Filters. Disposable micron membrane syringe filters do not need to change the membrane and clean, save the complex and time to prepare the work. Widely used in the laboratory. Be mainly applied to clarification, particle and aseptic filtration, etc.
The polycarbonate track-etch (PCTE) membrane filters can be dissolved with dipolar aprotic solvents such as dimethylformamide (DMF), dimethyl sulfoxide (DMSO) and n-methyl-2-pyrrolidone (NMP). The PCTE membrane filters can also be dissolved with the organic chlorinated solvents dichloromethane (DCM or methylene chloride) and trichloromethane (TCM or chloroform).
Choose a filter or membrane based on: 1) Chemical compatibility of the membrane and housing with your sample matrix. 2) Size and amount of particulates in the sample. 3) Potential interactions (binding) between the membrane and sample components. 4) Special considerations such as requirement for prefilter or inorganic ion certification.
Hydrophilic PTFE series pleated filter cartridge is contructed of hydrophilic PTFE membrane which has excellent chemical compatibility and corrosion resistance. The membrane is hydrophilic which can filter liquid directly without pre-wetting to save the operation time.
