Real-World Testing: Putting Nalge Nunc Square Media Bottles with Septum Closure, PETG, Sterile, NALGENE 342023-0060 to the Test

First Use Experience

My first practical application for the Nalge Nunc Square Media Bottles with Septum Closure, PETG, Sterile, NALGENE 342023-0060 was in preparing a batch of specialized cell culture media that required the aseptic addition of growth factors. I was working in our mobile field laboratory, a repurposed shipping container equipped for advanced biological research, which can be susceptible to fluctuations in temperature and dust ingress. The conditions, while controlled to a degree, are not as pristine as a dedicated cleanroom.

The performance in these conditions was, frankly, exceptional. The bottles stood firmly on the workbench thanks to their square profile, preventing any accidental tipping. Puncturing the silicone/PTFE closure with septum with a sterile syringe was smooth, and the seal immediately felt secure upon withdrawal. There was no sign of leakage or residual air ingress, which gave me immense confidence in the integrity of the media.

Ease of use was a significant win. The 24-415 cap size offered a comfortable grip for both applying pressure during the initial puncture and for re-sealing if necessary, though the latter was rarely required due to the nature of the septum. I anticipated a potential learning curve with the septum, perhaps difficulty in penetrating it or issues with it sealing afterward, but my fears were unfounded. The material of the septum provided just the right amount of resistance, allowing for easy penetration with standard laboratory needles.

My only minor surprise, and it’s a subtle one, was the slight “give” in the PETG material when squeezed firmly.
