Real-World Testing: Putting Nalge Nunc MF75 Vacuum Filter Units, PES Membrane, Sterile, NALGENE 566-0020 Complete Units With Supor Machv Pes Membrane, Case of 12 to the Test

First Use Experience

I tested the Nalge Nunc MF75 Vacuum Filter Units in a simulated field lab environment, filtering cell culture media. The unit connected easily to my vacuum pump via the quick-disconnect tubing adapter on the side arm. The filtration process was noticeably faster compared to standard cellulose acetate filters I’d used in the past.

The Supor machV membrane lived up to its reputation, maintaining a steady flow rate even as the media became more viscous. I encountered no clogging or unexpected flow interruptions, even with particulate-heavy solutions.

Extended Use & Reliability

After several weeks of consistent use, the Nalge Nunc MF75 Vacuum Filter Units proved to be remarkably reliable. I’ve yet to experience any failures or contamination issues across multiple units from the case. The durability of the plastic components is impressive; even after repeated handling and connection/disconnection to the vacuum source, the units show no signs of stress or cracking.

Cleaning is essentially non-existent, as these are single-use, disposable units. Disposing of the used filters is straightforward, and the pre-sterilized packaging minimizes any risk of contamination during storage. Compared to reusable filtration systems that require meticulous cleaning and autoclaving, the Nalge Nunc MF75 provides a significant time saving and reduces the potential for errors.
