Samples were prepared in chloroform (1 mg mL –1), left to dissolve for 24 h, and then passed through a PTFE syringe filter (0.45 μm pore diameter) prior to SEC analysis. 1 H nuclear magnetic resonance (NMR) spectra were collected with a Bruker DPX 400 MHz spectrometer at room temperature.
PTFE is a hydrophobic membrane and chemically resistant to virtually all solvents. It can be used for working with aggressive media such as strong acids, alcohols, bases, aromatics. The units are ready-to-use and allow for simple, rapid and reliable ultra-cleaning of small volume samples for HPLC or
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. According to DuPont, its melting point is 600 K (327 °C; 620 °F).

Microporous pleated filter element, the main filter material is : Stainless steel wire mesh, sintered wire mesh,Polypropylene, Hydrophobic PTFE, Hydrophilic PTFE,Polyether sulfone, Nylon, etc. Most of the raw materials are imported from abroad.Pleated filter element is a kind of deep filtration filter,
PVDF (homopolymers and copolymers) is generally synthesized by the free radical polymerization of 1,1-difluoroethylene (CH 2 =CF 2 ). The polymerization takes place in the suspension or emulsion from 10-150°C and pressure of 10-300 atm. The material obtained is then processed into film or sheets.
