Product Description
When precision matters in your lab work, the Whatman MP21 ST membrane filter delivers consistent performance. Designed for critical filtration tasks, this 0.45µm filter ensures reliable particle retention while maintaining high flow rates. Whether you’re working in microbiology, environmental testing, or pharmaceutical research, this filter provides the clarity and accuracy your experiments demand.
What sets the MP21 ST apart is its mixed cellulose ester construction, offering excellent chemical compatibility and low extractables. The smooth surface minimizes particle binding, making it ideal for both qualitative and quantitative analysis. Researchers trust Whatman filters for their reproducibility, and this model is no exception.
Available in convenient pack sizes of 100, you can choose between 47mm or 50mm diameters to match your filtration setup. The uniform pore structure guarantees consistent results, batch after batch. For labs that can’t compromise on quality, this filter is a smart investment.

Why This Filter Stands Out
The MP21 ST isn’t just another lab filter—it’s engineered for demanding applications. Its hydrophilic nature means it wets easily without requiring alcohol pre-treatment, saving you time in sample preparation. The filter’s strength and flexibility make handling simple, reducing the risk of tears during use.
In microbiological testing, this filter excels at retaining bacteria and other microorganisms while allowing clear visualization of colonies. Environmental scientists appreciate its ability to handle varied sample matrices without clogging. The 0.45µm rating strikes the perfect balance between retention efficiency and flow rate.
When you buy Whatman MP21 ST filters online from eqipped, you’re getting a product backed by decades of filtration expertise. Each pack undergoes strict quality control to ensure you receive filters that meet Whatman’s exacting standards.
Practical Applications
This versatile filter finds use across multiple disciplines:
Microbiology labs rely on it for bacterial enumeration and water quality testing. Pharmaceutical researchers use it for sterile filtration of buffers and media. Environmental scientists trust it for particulate analysis in air and water samples.
Its compatibility with common solvents makes it suitable for HPLC sample preparation and general lab filtration. The filter’s low protein binding characteristics also make it valuable in biological sample processing.
Handling and Storage Tips
To maintain optimal performance, store your filters in their original packaging away from direct sunlight and extreme temperatures. Always handle with clean forceps to prevent contamination. For best results, use within the recommended shelf life period indicated on the packaging.
When preparing for filtration, ensure your apparatus is clean and properly assembled. The filter should lie flat against the support screen without wrinkles. For critical applications, consider performing a blank test to verify the filter’s integrity before use.
These filters have a 0.45 micrometer pore size, ideal for general laboratory filtration and particle retention.
Can I use these filters for sterile filtration?
Yes, the 0.45µm rating is suitable for many sterile filtration applications, though you should validate for your specific process.
How many filters come in each pack?
Each pack contains 100 filters, available in either 47mm or 50mm diameters.
What materials are these filters made from?
The MP21 ST filters are composed of mixed cellulose esters, offering excellent chemical compatibility.
Where can I buy authentic Whatman MP21 ST filters online?
You can purchase genuine Whatman filters from eqipped, ensuring you receive quality products with proper documentation.
