Real-World Testing: Putting Eppendorf epTIPS Pipet Tips 022492101 Quality Tips, Case of 200 to the Test
First Use Experience
My initial testing ground was a series of serial dilutions for bacterial cultures. The precision in these dilutions is key for accurate downstream analysis. I appreciated the snug fit of the Eppendorf epTIPS onto my pipette, eliminating any concerns about leakage or inconsistent aspiration. The tips performed admirably, even when pipetting sticky glycerol stocks.
The humidified incubator environment where I conducted the assays presented no challenges to the tips; their robust construction prevented any warping or deformation. The smooth inner surface of the tips seemed to minimize liquid retention, leading to more accurate volumes dispensed with each aliquot. There were no surprises; the tips performed exactly as Eppendorf advertised.
Extended Use & Reliability
After several weeks of consistent use across a variety of applications, including PCR setup and protein assays, the Eppendorf epTIPS continued to impress. The tips showed no signs of degradation, even after repeated autoclaving (although they are not explicitly advertised as autoclavable, quality plastics can usually withstand the process). The consistent performance significantly improved the reproducibility of my experiments.
The epTIPS surpassed my previous experiences with other pipette tips. I noticed a marked decrease in the number of experimental replicates needed to achieve statistical significance, thanks to the improved pipetting precision. Cleaning was also straightforward, with the tips exhibiting excellent chemical resistance. The reliability and durability of the tips made them a worthwhile investment for my lab.
