“Our chromatography work deals with many harsh chemicals used to extract and elute the compound of interest. Purity of chemicals and consumables is critical in our field of work. We use large numbers of inert glass tubes and subsequently produce either heaps of non-recyclable glass waste of full basins of washables glass tubes. Moreover, we often experience loss of precious clinical sample due to glass breakage during the centrifugation process. The excellent quality of 25 mL polypropylene (PP) tubes from Eppendorf allowed us to substitute the glass tube’s usage and reduced glass breakage hazard to zero, without compromising the chromatography quality. Comparable peak separation and elution were detected with Eppendorf PP tubes in contrast to borosilicate glass tubes, with no interfering peak observed from possible UV-absorbing leachables, even if detected at very low noise value. Integration of the Eppendorf 25 mL tubes into our targeted liquid chromatography detection workflow has saved us time in cleaning and reduced glass waste with equivalent quality of results.”

“It‘s never easy to extract pure RNA, especially when the process involves a myriad of cells, and most of them do not have an optimized protocol. Therefore, the quality of the materials used is crucial to avoid unexpected results. In our laboratory, we can only accept the purest RNA to understand genetic regulation in different cellular stages. Since we started using the Eppendorf 25 mL tubes, we discard fewer samples. The transparency of the Eppendorf 25 mL tubes allows us to perfectly visualize RNA pellets and separate them from other crystals formed during the process. Furthermore, since we have been using Eppendorf
25 mL tubes, we have never again had problems with organic solvents dissolving the containers. Their height also makes them very comfortable to work with in the laminar flow hood. For those reasons, Eppendorf 25 mL tubes are now part of our day-to-day work, and they are here to stay.”
