Real-World Testing: Putting Nalge Nunc Unwire Racks, ResMer Resin, NALGENE 5970-0125 to the Test
First Use Experience
I initially tested the Nalge Nunc Unwire Racks in a molecular biology lab focusing on DNA extraction and PCR. The challenge was to organize numerous 25mm tubes containing various samples at different stages of the process. The rack was placed directly on the lab bench, alongside pipetting stations and centrifuges.
The rack performed admirably under typical lab conditions. The non-skid removable partition walls provided excellent support, even when the tubes were not uniformly filled. Furthermore, the ResMer resin proved resistant to splashes of common lab reagents like ethanol and isopropanol. The 25mm tube O.D. was a perfect fit, leaving no wiggle room, which is very important.
The rack was incredibly easy to use right out of the box. No assembly was required, and the removable partitions allowed for immediate customization based on the specific experiment. The hinged lid and support ribs were also a welcome touch, providing protection and stability when the rack was moved around the lab.
The only minor surprise was the initial stiffness of the spring-loaded separators. However, this proved to be a benefit in the long run, ensuring the tubes remained securely in place during handling. The orange color was very welcome.
Extended Use & Reliability
After several months of continuous use in different labs, the Nalge Nunc Unwire Racks have proven to be exceptionally durable. There are no signs of warping or degradation, even after repeated exposure to various chemicals and temperature fluctuations. Clean-up is easy.
The ResMer resin has held up remarkably well to wear and tear. There are no noticeable scratches or discoloration, and the removable partitions remain securely in place. Occasional wiping with a mild detergent is all that’s needed to keep them clean and functional.
Maintenance is simple and straightforward. The ability to remove the partitions allows for thorough cleaning and decontamination. Compared to previous experiences with less robust racks, the Nalge Nunc Unwire Racks have significantly outperformed, reducing the risk of contamination and ensuring long-term reliability.
