PVDF Membrane Filters

Tisch Scientific PVDF membrane filters (Polyvinylidene Fluoride), also known as microporous membranes, are known to exhibit high efficiency for particle removal. PVDF membranes have a low critical surface energy and are naturally hydrophobic. These PVDF membranes will not dampen with aqueous fluids. They are known for their wide chemical compatibility, high temperature resistance and low starting resistance. They are most commonly used in the chemical process, off shore oil, and plumbing industries.

Tisch Scientific offers an extensive selection of proven, yet affordable products that are in stock and ready to ship today. Selected for their durability, material quality and performance characteristics, our microfiltration devices deliver accurate, measurable results at a fraction of the cost. Available in a wide variety of materials, sizes, and in sterile and non-sterile options, they are a superior choice for use in environmental, biotechnology, food/beverage, agricultural and many other applications.

Our Polyvinylidene fluoride (PVDF) membranes filters ship from stock in one business day. Polyvinylidene fluoride (PVDF) membrane is a hydrophobic and microporous membrane, and is produced by the polymerization of vinylidene difluoride and ships from stock in one business day.

PVDF membrane filters possess a high binding capacity for proteins and nucleic acids for Western, Southern and Northern blotting methods. It is available as sheet, film, piping, plate, and an insulator for wires. PVDF is widely used in the chemical, semiconductor, medical, and defence industries along with Aviation and aerospace sector.

Properties of Tisch Scientific PVDF membranes

* PVDF exhibits piezoelectric and pyroelectric properties as it is a ferroelectric polymer.
* It exhibits high temperature capabilities and ageing resistance.
* PVDF is good to use with alcohols, proteins, weak acids, peptides, and other biomolecules while it must be avoided with strong acids, bases, ethers and ketones.
* PVDF has a low density of about 1.78, and is reasonably priced than other fluoropolymers.
* PVDF membranes are convenient to use and can be stripped easily, as this material is resistant to solvents.
* It has a relatively low melting point of 177 degree Celsius and melts easily
* It has a low critical surface energy and will not get dampen with aqueous fluids.
* It enables easy processing by blow molding, compression, injection and extrusion process.
* It enables high purity fluid transportation.

Applications of PVDF membrane filters

* PVDF possesses properties such as flexibility, low weight, low thermal conductivity, high chemical corrosion resistance, and heat resistance. It is because of combination of these properties that it is used as insulation on various types of electrical wires.
* PVDF is also used to manufacture strain gauges, lightweight transducers and tactile sensor arrays as it possesses advantageous piezoelectric properties. Piezoelectric panels made of PVDF are used on the scientific instrument of a space probe, which is used to measure dust density in the outer solar system.
* PVDF is used to manufacture of fluorocarbon replacements for nylon monofilament. As it is denser than nylon, it can easily sink faster.
* PVDF is used in immunoblotting as artificial membranes in the field of biomedical sciences. Dimension varying between 0.22 or 0.45 micrometers pore sizes, on which proteins are transferred using electricity, is generally preferred for this purpose.
* Lithium ion batteries are also composed of PVDF. As PVDF is chemically inert over the potential range used, and doesn’t react with electrolytes or lithium, it is used as binder material in the production of composite electrodes for lithium ion batteries.
* Due to its non-specific affinity for amino acids, PVDF membranes are used for western blots for immobilization of proteins.
