Real-World Testing: Putting Nalge Nunc EasyFlask Culture Flasks, Polystyrene, Sterile, NUNC 159934 Flasks With Filter Caps, Case of 30 to the Test

First Use Experience

I first tested the flasks in our cell culture lab, culturing mammalian cells for a gene expression study. I used multiple flasks to test batch consistency. The easy-to-open, self-standing bags made retrieving individual flasks simple, reducing the risk of accidental contamination.

The flasks performed reliably across multiple incubation conditions, including standard 37°C with 5% CO2 and high humidity. The filter caps facilitated consistent gas exchange, crucial for maintaining a stable pH within the culture medium. The slope shoulder design also prevented media from accidentally spilling into the neck of the flask, a minor but appreciated detail.

The EasyFlasks were surprisingly intuitive to use. The notch threading system allowed for quick opening, closing, and venting with just a 1/3 turn. No time was needed to get used to the design; it was straightforward from the start.

The only initial concern was the limited working volume (45-115 mL) compared to the total flask volume, but this was clarified by the surface area of the flask, which provides ample area for cell growth.

Extended Use & Reliability

After several weeks of continuous use, the Nalge Nunc EasyFlasks consistently delivered reliable performance. There were no signs of leakage or contamination issues, even with frequent handling and media changes. Batch-to-batch consistency was excellent.

The flasks held up well over time, showing no signs of degradation or deformation. The polystyrene material proved resistant to common laboratory chemicals, ensuring the integrity of the culture environment. The flasks’ graduations remained clear and easy to read.

Maintaining the flasks was simple. They are disposable, eliminating the need for time-consuming cleaning and sterilization procedures. Proper disposal after use prevented cross-contamination.

In contrast to reusable glass flasks requiring meticulous cleaning, the Nalge Nunc EasyFlasks offered significant time savings and reduced the risk of contamination. They outperformed standard disposable flasks that lacked features like the filter cap and optimized neck design.
