Real-World Testing: Putting Nalge Nunc Baffled Culture Flasks, Polycarbonate, NALGENE 4110-1000 to the Test
First Use Experience
My initial testing took place in our lab, focusing on culturing S. cerevisiae at room temperature (around 25°C) using a standard growth medium. The flask was placed on an orbital shaker, set to a controlled speed of 150 rpm to evaluate mixing and aeration. I meticulously monitored cell growth through optical density measurements at regular intervals. The setup mimicked a typical fermentation process I regularly conduct, allowing for a direct comparison.
The Nalge Nunc Baffled Culture Flasks, Polycarbonate, NALGENE 4110-1000 performed exceptionally well, even under humid conditions typical of our lab. The baffled design provided excellent mixing and aeration, preventing cell clumping and promoting uniform growth. The molded neck ridge also proved invaluable, providing a secure grip and reducing the risk of contamination during transfers.
The flask was easy to use right out of the box; however, determining the optimal shaker speed for my specific culture took a few initial runs. There were no major issues, but I did notice that the polycarbonate material was slightly more prone to static cling than glass, which attracted some dust particles initially.
Extended Use & Reliability
After several weeks of continuous use, the Nalge Nunc Baffled Culture Flasks, Polycarbonate, NALGENE 4110-1000 continued to perform reliably. The flask has been through numerous autoclave cycles without any signs of degradation, demonstrating the durability of the polycarbonate material. Cell growth remained consistently high, and the mixing performance never diminished.
Despite repeated autoclaving and exposure to various chemicals, the flask showed minimal signs of wear and tear. There were a few minor scratches on the surface, but these did not affect its functionality. The baffles remained firmly in place, and the molded neck ridge continued to provide a secure grip.
Cleaning and maintaining the flask was straightforward. After each use, the flask was thoroughly rinsed with distilled water and then autoclaved for sterilization. The smooth polycarbonate surface made it easy to remove any residual debris, and the flask dried quickly without leaving any water spots.
Compared to previous experiences with traditional Erlenmeyer flasks, the Nalge Nunc Baffled Culture Flasks, Polycarbonate, NALGENE 4110-1000 significantly outperformed them in terms of cell growth and consistency. The baffled design provided superior aeration and mixing, resulting in higher cell densities and more efficient fermentation.
