About PVDF Membrane Filter 0.45 um Pore Size HVLP04700

The Millipore Durapore HVLP04700 is a hydrophilic PVDF (Polyvinylidene Fluoride) membrane filter with a pore size of 0.45 m and a diameter of 47 mm. It is designed for clarifying filtration of biological solutions and offers high flow rates, throughput, low extractables, and broad chemical compatibility. It's also known for low protein binding, minimizing interaction with the sample and maximizing recovery. Here's a more detailed breakdown:

Material: Hydrophilic PVDF (Polyvinylidene Fluoride).
Pore Size: 0.45 m, which is commonly used for general microbiological filtration and for retaining bacteria and other microorganisms.
Diameter: 47 mm.
Hydrophilic: Attracts water, making it suitable for aqueous solutions.
Low Protein Binding: Minimizes interaction with proteins, which is important for many biological applications.
Applications: Clarifying filtration of biological solutions, sterilization (in some cases), and general filtration where low protein binding is desired.
Key Properties: High flow rates, high throughput, low extractables, and broad chemical compatibility.

Superior Filtration Efficiency

This PVDF membrane filter offers high retention and flow rate, making it suitable for removing particles larger than 0.45 m. Designed to handle a variety of solvents-including aggressive types-its hydrophobic nature supports robust, reliable performance for challenging samples. The smooth membrane surface not only increases filtration speed but also reduces contamination and binding of valuable analytes, thereby enhancing the overall efficiency of your filtration process.

Versatile Laboratory Applications

With a 0.45 m pore size and compatibility with aggressive solvents, this filter can be broadly utilized in different sample preparation scenarios. The non-sterile and autoclavable design means it can be sterilized as required, accommodating applications in drug discovery, quality control, environmental testing, and more. The high maximum operating temperature and strong chemical resistance further extend its usability across diverse research and industrial settings.

FAQ's of PVDF Membrane Filter 0.45 um Pore Size HVLP04700:

Q: How should the PVDF Membrane Filter 0.45 m be used in laboratory filtration processes?

A: The filter is designed for use in vacuum or pressure filtration systems. Simply place the 47 mm diameter membrane in a compatible holder, ensuring the smooth, white surface faces upwards. The filter efficiently retains particles at or above 0.45 m, making it suitable for liquid clarification, sample preparation, or analytical procedures involving aggressive solvents.

Q: What types of solvents and solutions are compatible with this PVDF membrane filter?

A: This membrane is highly compatible with a wide range of aggressive organic solvents and aqueous solutions due to its hydrophobic PVDF material. It can effectively filter samples in chemical, microbiological, and pharmaceutical labs, especially where challenging solvent resistance is required.

Q: When is it necessary to sterilize this membrane filter before use?

A: As the filter is supplied non-sterile (100 per pack), sterilization is recommended prior to any applications requiring aseptic or sterile conditions, such as microbiological media filtration or sensitive analytical work. The membrane is autoclavable and can withstand repeated sterilization at up to 120C.

Q: Where is this PVDF membrane filter manufactured and how can I source it in India?

A: These filters are manufactured, supplied, exported, and distributed by reputable companies in India. You can source them through authorized laboratory equipment suppliers, manufacturers, or traders catering to domestic and international markets.

Q: What is the main process for operating this filter under pressure or vacuum conditions?

A: After placing the membrane in a filtration holder, apply gentle vacuum or positive pressure to drive the sample through the filter. The filter's high flow rate and bubble point of >1.0 bar ensure quick filtration without compromising retention efficiency or sample integrity.

Q: What benefits does this PVDF membrane offer over other filter materials?

A: The PVDF filter provides superior chemical resistance, high flow rates, and reliable retention of particles 0.45 m. Its hydrophobic and smooth surface reduces protein binding, preserves sample purity, and extends suitability for solvents that may degrade other membrane materials.
