Real-World Testing: Putting Nalge Nunc MF75 Vacuum Filter Units, PES Membrane, Sterile, NALGENE 569-0020 Complete Units With Supor Machv Pes Membrane, Case of 12 to the Test
First Use Experience
I first tested the Nalge Nunc MF75 Vacuum Filter Units in our cell culture lab, filtering cell culture media supplemented with serum. We needed sterile media for several ongoing experiments, and the units promised quick and reliable sterilization. The filtration process was surprisingly smooth and noticeably faster than our older cellulose acetate filters.
The Supor machV PES membrane demonstrated excellent flow rates, even with viscous serum-containing media. There were no signs of clogging or reduced filtration speed during the entire process, even when filtering larger volumes. The ease of use was also notable; the quick-disconnect tubing adapters allowed for simple and secure attachment to our vacuum source. I didn’t experience any issues with leaking or backflow, which was a welcome change from some less-robust systems I’d used previously.
Extended Use & Reliability
After several weeks of consistent use, the Nalge Nunc MF75 Vacuum Filter Units have proven to be a reliable workhorse in our lab. We have used them to filter a wide range of solutions, including antibiotics, buffers, and even some protein solutions. The durability of the units is impressive; even after repeated use and cleaning, they show no signs of wear and tear.
Maintaining the units is relatively straightforward; the materials are resistant to most common laboratory cleaning agents. I ensure to rinse them thoroughly with distilled water after each use to prevent any buildup or residue. Compared to our previous filtration methods, the NALGENE units have significantly reduced our preparation time and improved the overall sterility of our solutions.
Breaking Down the Features of Nalge Nunc MF75 Vacuum Filter Units, PES Membrane, Sterile, NALGENE 569-0020 Complete Units With Supor Machv Pes Membrane, Case of 12
Specifications
- Capacity: 500 mL. This capacity is ideal for most standard laboratory applications, allowing for the filtration of a significant volume of solution in a single step.
- Pore Size: 0.2 µm. The 0.2 µm pore size ensures the removal of bacteria and other microorganisms, producing sterile solutions for cell culture and other sensitive applications.
- Membrane Diameter: 90 mm. This large membrane area maximizes flow rate and throughput, reducing filtration time and improving efficiency.
- Membrane Type: Supor Machv PES (Polyethersulfone). The Supor Machv PES membrane is known for its low protein binding, low extractables, and fast flow rate, making it an excellent choice for filtering sensitive biological solutions.
- Sterility: Radiation-sterilized. The units are certified radiation-sterilized, ensuring that they are free from contaminants and ready for immediate use in sterile environments.
- Noncytotoxic and nonpyrogenic. The units are certified noncytotoxic and nonpyrogenic, making them safe for use with cell cultures and other biological applications.
- Unit: Case of 12. The case of 12 provides a convenient supply of units, reducing the need for frequent reordering.
These specifications are critical for ensuring the reliability and effectiveness of the filtration process. The Supor Machv PES membrane minimizes protein loss, the 0.2 µm pore size guarantees sterility, and the large membrane area speeds up filtration.
Performance & Functionality
The Nalge Nunc MF75 Vacuum Filter Units perform exceptionally well in terms of sterility, flow rate, and ease of use. The units consistently produce sterile filtrates, as confirmed by our routine sterility testing. The high flow rate of the Supor machV PES membrane significantly reduces filtration time compared to other filter types.
A major strength is the complete, ready-to-use design, which simplifies the filtration process and minimizes the risk of contamination.
