Real-World Testing: Putting Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 110 to the Test
First Use Experience
The initial testing ground for the Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 110 was in our microbiology lab, specifically during a series of experiments involving serial dilutions of bacterial cultures. The pipets were used to accurately transfer aliquots of culture media into sterile diluent, a critical step for obtaining reliable colony counts.
The pipets performed admirably under various conditions. While we generally maintain a controlled lab environment, we did simulate some less-than-ideal scenarios, including slightly increased humidity and temperature fluctuations, to assess their performance stability. The glass construction remained inert, and the graduations remained clear and easy to read, regardless of external conditions.
Using the Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 110 was relatively straightforward, although it did require a slight adjustment for users accustomed to exclusively working with disposable plastic pipets. The glass construction demanded a more delicate touch to avoid breakage, and mastering the proper technique for “blowing out” the last drop of liquid to achieve accurate volume delivery took a few practice runs. The pipets were surprisingly comfortable to use, given their length, and the color-coding significantly reduced the risk of selecting the wrong size.
The only initial issue encountered was a slight learning curve for some team members regarding the “blow-out” technique, which is critical for the advertised accuracy. After a brief training session, this was quickly resolved.
Extended Use & Reliability
After several weeks of consistent use in the lab, the Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 110 have proven to be remarkably robust. Despite repeated sterilization cycles in an autoclave and exposure to various chemical solutions, the glass remains pristine, and the graduations show no signs of fading or degradation.
Durability has been exceptional, with no breakages occurring despite the occasional accidental bump or jostle. The KIMAX glass has clearly proven its worth, withstanding the rigors of a busy lab environment.
Maintaining the Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 110 is a breeze. A simple wash with laboratory detergent followed by autoclaving ensures complete sterilization, and the smooth glass surface prevents the buildup of residue or contaminants.
In comparison to previous experiences with disposable plastic pipets, the Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 110 significantly outperform in terms of accuracy, durability, and long-term cost-effectiveness.
