What is PES membrane?
What is PES membrane?
Polyethersulfone (PES) membrane for aqueous solutions provides removal of fine particles, bacteria, and fungi making it a versatile membrane for applications such as sample preparation, sterile filtration and infusion therapy.
What are PVDF filters used for?
PVDF membrane filters are commonly used for purification during sterilizing or clarifying procedures. Sterile PVDF filter membranes are often used for biological sterilization filtration after hydrophilic treatment.
Is PES low protein binding?
Polyethersulfone (PES) and polyvinylidene fluoride (PVDF) membranes are typically used for biological sample filtration and are claimed to provide very low protein binding.
What is PES polymer?
Polyethersulfone (PES) Polyethersulfone (PES) is an amorphous, transparent, and pale amber high-performance thermoplastic. It is the most temperature resistant, transparent commercially available thermoplastic resin. It is a high temperature engineering thermoplastic with high stability and mechanical strength.
Is PES hydrophilic or hydrophobic?
PES is hydrophilic in nature due to its molecular structure which facilitates hydrogen bonding with water molecules.
What is the difference between PVDF and nitrocellulose membrane?
PVDF membranes have a higher protein binding capacity than nitrocellulose. The protein binding capacity of PVDF ranges from 150-200 µg of protein/cm2 and nitrocellulose ranges from 80-100 µg of protein/cm2. Although PVDF has a higher binding capacity, it could result in increased background in some circumstances.
What is PES membrane filter?
PES is an inherently hydrophilic membrane that wets out quickly and completely resulting in fast filtration with superior flow rates and high throughputs. Polyethersulfone membrane is compatible with EtO, gamma irradiation, and autoclave methods of sterilization.
