About MF Millipore Membrane Filter 5 um pore size SMWP04700 Diameter 47mm

An MCE (Mixed Cellulose Esters) membrane filter with a 1.2 m pore size, manufactured by Millipore (now part of Merck), is a type of filter commonly used in analytical and research applications. These filters are known for their versatility in biological and environmental monitoring due to their inertness and availability in various pore sizes and configurations. The 1.2 m pore size indicates that the filter can effectively retain particles and microorganisms larger than 1.2 micrometers in size. Here's a more detailed description:

Material: The filter is made from a mixture of cellulose acetate and cellulose nitrate, known for its biological inertness.
Pore Size: The 1.2 m pore size means the filter will retain particles and microorganisms larger than 1.2 micrometers, allowing smaller particles and fluids to pass through.

Precision Filtration for Laboratory Applications

The MF Millipore Membrane Filter SMWP04700 ensures reliable retention of particles from liquids and gases, making it suitable for diverse analytical needs. Its mixed cellulose esters (MCE) construction offers hydrophilicity, high throughput, and excellent chemical durability. The 5 m pore size is ideal for clarification, microbiological analysis, and air or gas monitoring, providing consistent results every time.

Excellent Flow Rate and Low Protein Binding

With a flow rate of 100 mL per cm2 per minute at 10 cm Hg, this membrane filter ensures quick processing of samples without sacrificing performance. Its low protein binding qualities preserve sample integrity, reducing loss during filtration. The plain surface is compatible with most laboratory filtration devices, simplifying integration into existing protocols.

Versatile and Durable Design

This white, round, 47 mm filter is autoclavable at 121C and can withstand up to 130C, meeting rigorous sterility and temperature requirements. The robust membrane works with common lab filtration setups and maintains performance over a five-year shelf life if stored correctly. Each pack contains 100 filters for convenient laboratory stocking.

FAQ's of MF Millipore Membrane Filter 5 um pore size SMWP04700 Diameter 47mm:

Q: How do I properly use the MF Millipore Membrane Filter SMWP04700 in laboratory filtration processes?

A: To use the SMWP04700 membrane filter, securely place it in your filtration apparatus, ensuring the plain surface is oriented correctly. Pass your liquid or gas sample through the filter, maintaining conditions within the maximum temperature (130C) and pressure (5.2 bar) limits for optimal performance. The filter is compatible with standard lab filtration equipment.

Q: What are the key benefits of choosing this membrane filter for analytical applications?

A: The SMWP04700 filter offers high throughput, low protein binding, and hydrophilic properties, ensuring efficient sample processing and minimal analyte loss. Its versatile 5 m pore size and compatibility with a range of laboratory filtration systems support various tasks such as particle analysis, microbiological studies, and clarification.

Q: When should I consider autoclaving these filters, and how should I perform the process?

A: These membrane filters can be autoclaved at 121C for sterilization when required. Autoclave before use if sterility is crucial to your protocol. Place filters in appropriate autoclave-safe pouches or containers, and follow your standard laboratory autoclaving procedures. Do not exceed the maximum temperature of 130C.

Q: Where is the best place to store unused membrane filters to maximize their shelf life?

A: For optimal shelf life (up to five years from manufacture), store unused filters in a cool, dry place away from direct sunlight and excessive heat. Keep them in their original packaging until needed to prevent contamination and moisture exposure.

Q: What applications are most suitable for the MF Millipore SMWP04700 membrane filter?

A: These filters are ideal for particle and microbiological analysis, clarification of samples, and monitoring air or gas quality in laboratory settings. The 5 m pore size allows for effective retention of larger particulates and microbial colonies in both liquid and gaseous samples.

Q: How can I ensure compatibility with my existing laboratory filtration equipment?

A: The SMWP04700 membrane filter is designed as a round disc with a 47 mm diameter, making it compatible with most traditional and standard laboratory filtration devices. Simply verify the diameter matches your equipment's specifications for a secure fit.

Q: What should I avoid when using or storing these membrane filters?

A: Avoid exposing the filters to direct sunlight, excessive heat, or moisture, as these conditions can degrade the material over time. Do not use solvents that may dissolve mixed cellulose esters, and always operate within the recommended pressure and temperature limits to maintain filter performance and integrity.
