2007/4/20 · A special hydrophilic/hydrophobic composite membrane of CA and PTFE was prepared to serve as the carrier of lipase for the chiral separation of racemic ibuprofen. The results of separation were studied from three aspects: lipase activity, enantioselectivity and stability.
Hydrophobic PTFE is generally regarded as having the best solvent resistance of any membrane, particularly aggressive organic solutions. Only Aijiren Captiva premium syringe filters are shipped with an HPLC or LC/MS Certificate that guarantees extremely low levels of observed extractables.

2020/11/30 · While bare PTFE membrane suffered from serious fouling and wetting problems due to the strong hydrophobic-hydrophobic interaction between contaminants and membrane surface. The outstanding performance of the composite membrane was originated form the inherent superiorities of GO coating, such as ultrafast water permeation, nanocapillary effect, negative surface charge and
2018/8/3 · With addition of PTFE particles, the water contact angle of obtained membranes increased to 136.8 which illustrated that the membranes had excellent hydrophobicity. The reason was that the blending polymer PTFE possessed better hydrophobicity and weakened the surface free energy of obtained membranes.

Polycap TF filters are made with durable, hydrophobic polytetrafluoroethylene (PTFE) membranes in a polypropylene housing for use with organic solvents and chemically aggressive solutions. PTFE filter membrane is resistant to most solvents Available in 0.05, 0.1, 0.2, 0.45, and 1.0 µm pore
Polytetrafluoroethylene (PTFE) syringe filters are inherently hydrophobic but are also available in hydrophilic options. PTFE membranes are are very resistant to solvents, acids, and bases and are ideal for filtering non-polar liquids and gases, including filtering and de-gassing chromatography solvents.
Inside the syringe filter polytetrafluoroethylene is used as membrane material. The hydrophobic PTFE membrane is very resistant towards all kinds of solvents as well as acids and bases. Flushing with alcohol, followed by water, makes the originally hydrophobic membrane more hydrophilic. Labeled for method validation and certification.
