Let’s Dive into Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020-10, Case of 12
The Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020-10, Case of 12 represent a cornerstone of any well-equipped lab, offering precision and reliability for liquid handling. Manufactured by Kimble/Kontes, a name synonymous with quality labware, these pipets are designed for accuracy and ease of use in a variety of chemical applications.
My search for a reliable and reusable set of measuring pipets led me to these Kimble/Kontes models. The need for consistent and accurate measurements in formulating custom cleaning solutions for delicate tactical gear, particularly optics and waterproof membranes, demanded a tool I could trust.
Upon unboxing the case of 12 pipets, the immediate impression was one of quality. The glass felt robust yet delicate, and the color-coding was a welcome feature for quick identification. This set appeared ready to withstand the rigors of daily use in a makeshift lab environment.
Compared to disposable plastic pipets, the Kimble/Kontes KIMAX offered a clear advantage in terms of reusability and potential long-term cost savings. I also considered a digital pipette, but for the volumes and specific gravity measurements needed for my cleaning formulas, the classic Mohr pipet design with its clear graduations seemed more practical and less prone to electronic failure in a humid environment. My initial excitement was high, anticipating the enhanced accuracy and control these pipets would bring to my work.
Real-World Testing: Putting Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020-10, Case of 12 to the Test
First Use Experience
My initial testing ground for the Kimble/Kontes KIMAX pipets was in the development of a new cleaning solution for rifle scopes. This involved precise measurement of various solvents and surfactants to achieve the desired cleaning properties without damaging the lens coatings.
The pipets performed admirably, even with liquids of varying viscosities. The graduation markings were clear and easy to read, allowing for accurate dispensing. I was particularly impressed with the control offered by the Mohr design, allowing me to deliver precise volumes drop by drop.
There was a slight learning curve in mastering the proper technique for dispensing the liquid without creating air bubbles or dripping. However, after a few practice runs, I was able to achieve consistent and repeatable results.
Extended Use & Reliability
After several weeks of use, the Kimble/Kontes KIMAX pipets have proven to be reliable and durable. The glass has shown no signs of etching or degradation from the various chemicals used.
Cleaning the pipets after use is relatively straightforward, requiring only a thorough rinse with distilled water and a mild detergent. They are also autoclavable for sterilization, adding another layer of safety and hygiene.
Compared to the inexpensive plastic pipets I previously used, the Kimble/Kontes offer a significantly improved level of accuracy and control. The Class B tolerance, while not the highest available, is more than sufficient for my applications and provides a noticeable improvement in the consistency of my results.
