HAWP04700
MCE Membrane Filter, 0.45 micron Pore Size
filter diam. 47 mm, hydrophilic, white, pkg of 100 discs
General description
Biologically inert mixtures of cellulose acetate and cellulose nitrate have made MF-Millipore membrane filters one of the most widely used membranes in analytical and research applications.
MF-Millipore filters without Triton surfactant contain minimum amounts of wetting agent and have a lower water extractable content than standard MF-Millipore filters.
Features & Benefits:
- Versatile filter for biological and environmental monitoring applications
- Available in a range of pore sizes, colored black or white, with or without a gridded surface
- Compatible with ethylene oxide, gamma irradiation, and autoclave sterilization methods
Filter Code: HAWP

FAQ's of HAWP04700 Filter Paper:
Q: How should the HAWP04700 Filter Paper be used in laboratory filtration processes?
A: Place the 47 mm cellulose nitrate membrane filter in an appropriate filter holder, ensuring the smooth surface is facing the sample. Run your biological or chemical liquid sample through at a controlled pressure, not exceeding 7 psi to ensure the flow rate and retention works optimally.
Q: What are the main applications of this filter paper?
A: The HAWP04700 Filter Paper is primarily used for qualitative filtration in biology, chemistry, and microbiology laboratories. It supports processes such as sample clarification, microbial analysis, and general solution filtration where a 0.45 m retention is needed.
Q: When should I choose this filter over other types?
A: Choose the HAWP04700 when your protocols require high-speed throughput, reliable retention of fine particulates (>0.45 m), and compatibility within a pH range of 4-8. It is especially useful where non-sterile membranes are suitable and you need smooth, particle-free finishes in filtrates.
Q: Where can this filter paper be effectively utilized?
A: This membrane filter can be used in academic, industrial, or research laboratories across India and globally-anywhere biological or chemical filtrations are required, and the membrane's temperature and pH specifications meet your procedures.
Q: What is the process for disposing of used filter paper discs?
A: After use, dispose of the filter paper according to your laboratory's chemical and biological waste management protocols. Avoid reusing the discs to prevent cross-contamination and ensure analytical accuracy.
Q: What operational benefits does the 0.45 m pore size provide?
A: A 0.45 m pore size enables efficient removal of bacteria and fine particles while allowing high flow rates, making the filter ideal for applications where clarity and sample throughput are equally important.
