Product Description
When precision matters in your lab work, the Whatman ME25 ST membrane filter is the go-to choice for researchers, students, and educators across India. Designed for reliability, these cellulose ester filters provide consistent performance in critical applications like microbiological testing, particle analysis, and sterile filtration. The 0.45µm pore size ensures efficient retention of bacteria and fine particles, making them indispensable in labs where accuracy is non-negotiable.
Whether you’re filtering culture media, testing water samples, or preparing sterile solutions, these membrane filters deliver results you can trust. The pack sizes of 47mm and 50mm cater to different experimental setups, while the pack of 100 ensures you always have enough filters on hand for repeated use. eqipped brings you these high-quality Whatman filters with the convenience of online ordering, so you can focus on your research without supply chain worries.
What sets the ME25 ST apart is its balance of strength and flow rate. Unlike cheaper alternatives that tear under pressure or clog prematurely, these filters maintain integrity even with challenging samples. Their smooth surface allows for easy colony counting in microbiology applications, while the hydrophilic nature ensures quick wetting for faster filtration. For labs that demand both performance and value, this is the filter that checks all boxes.
Students working on university projects will appreciate how these filters simplify their workflow. No more struggling with inconsistent results or questionable quality. Educators can confidently recommend these for practical sessions, knowing students will get reliable data every time. And for researchers publishing critical findings, the Whatman name carries the credibility your work deserves.
Remember, proper storage is key to maintaining filter performance. Store in a cool, dry place away from direct sunlight to preserve the membrane’s properties. Always handle with clean forceps to avoid contamination. When you buy Whatman ME25 ST membrane filters online from eqipped, you’re not just getting a product – you’re investing in the accuracy of your scientific work.
FAQs
What is the difference between 47mm and 50mm Whatman ME25 ST filters?
The size difference allows compatibility with different filtration setups. 47mm filters fit most standard filter holders and are ideal for small-volume samples, while 50mm filters accommodate larger sample volumes and fit larger diameter filter funnels. Both maintain the same 0.45µm pore size and performance characteristics.
Can these filters be autoclaved for sterilization?
Yes, Whatman ME25 ST membrane filters can be autoclaved at 121°C for 15 minutes without compromising their integrity or filtration performance. This makes them suitable for applications requiring sterile filtration where pre-sterilized filters aren’t available.
Are these filters suitable for protein binding studies?
While cellulose ester filters have lower protein binding compared to nylon, they aren’t completely protein-binding free. For applications where minimal protein binding is critical, consider Whatman’s dedicated low protein binding filters. However, for general microbiological and particulate filtration, these perform excellently.
How should I store these membrane filters to maintain their quality?
Store filters in their original packaging in a cool, dry environment away from direct sunlight and chemical fumes. Avoid exposure to high humidity which can affect the membrane’s properties. Always handle with clean forceps to prevent contamination before use.
Can I use these filters for air monitoring applications?
While primarily designed for liquid filtration, these filters can be used for particulate air monitoring when placed in appropriate sampling cassettes. However, for dedicated air monitoring, consider filters specifically designed for that purpose as they may offer better particle retention and flow characteristics for air sampling.
