Product Description
When precision matters in your lab work, the Whatman Polydisc Filter 6724-5045 delivers reliable performance for critical filtration tasks. Designed for researchers, students, and educators, these disposable filters ensure sterile conditions for microbial analysis, particle removal, and sample preparation. Whether you’re working with aqueous solutions or organic solvents, the range of membrane materials—GF/PESS, PTFE, and PES—offers compatibility with diverse applications.
The 0.1µm to 1.0µm pore sizes cater to different filtration needs, from ultrafine particle retention to general clarifications. Each filter is individually packaged to maintain sterility, reducing contamination risks in sensitive experiments. The Polydisc design fits standard filtration setups, making it a seamless addition to your lab workflow.
For labs prioritizing efficiency, the pack sizes (10 or 50 filters) provide flexibility for both small-scale and bulk requirements. Students conducting microbiology projects or researchers validating water quality will find these filters indispensable. The PTFE variants, in particular, excel in aggressive chemical environments, while PES membranes are ideal for biological samples.

FAQs
What pore size should I choose for bacterial filtration?
For most bacterial retention, a 0.2µm or 0.45µm filter is recommended. The 0.2µm size is ideal for mycoplasma removal, while 0.45µm suits general bacterial filtration.
Can these filters be used with organic solvents?
Yes, the PTFE membranes are chemically resistant and compatible with organic solvents like alcohols, acids, and bases. Avoid using PES filters with aggressive solvents.
Are these filters pre-sterilized?
All Whatman Polydisc filters are gamma-irradiated for sterility, ensuring they’re ready for immediate use in aseptic applications.
How do I select between GF/PESS and PES membranes?
GF/PESS filters are glass fiber-based, offering high flow rates for particulate removal. PES membranes provide lower protein binding, making them better for biological samples.
What’s the shelf life of these filters?
When stored in their original packaging at room temperature, the filters retain sterility for up to 5 years. Check the expiration date on the pack.
