Real-World Testing: Putting Nalge Nunc Disposable Erlenmeyer Flasks, PETG, Sterile, NALGENE 4113-1000, Case of 6 to the Test
First Use Experience
The Nalge Nunc Disposable Erlenmeyer Flasks were put to the test in our cell culture lab, specifically for growing mammalian cells in suspension. They were used inside a sterile biological safety cabinet to maintain sterility and prevent contamination during use. The flasks were filled with cell culture media, inoculated with cells, and placed on an orbital shaker in a temperature-controlled incubator.
The flasks performed admirably under these controlled conditions. They were easy to handle and the screw caps provided a leak-proof seal, even under the agitation of the orbital shaker. There were no issues with clarity of the PETG, making it easy to monitor cell growth using microscopy.
Initially, there were no issues or surprises. The flasks performed exactly as intended, providing a sterile and reliable vessel for cell culture.
Extended Use & Reliability
After several weeks of consistent use, the Nalge Nunc Disposable Erlenmeyer Flasks maintained their integrity and reliability. There were no signs of degradation or leaching of the PETG plastic. The cells grew well within the flasks and we observed no instances of contamination that could be attributed to the flasks themselves.
The flasks demonstrated excellent durability for single-use labware. Despite being disposable, they held up well to repeated handling and agitation. Disposal was straightforward and efficient, reducing the time and resources spent on cleaning and sterilizing glassware.
Compared to our previous experiences with reusable glass flasks, these disposable flasks offered a significant improvement in convenience and reduced contamination risk. They met and even exceeded our expectations for disposable cell culture vessels.
