Let’s Dive into Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class A, Color-Coded 37025 1110, Pack of 6
The Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class A, Color-Coded 37025 1110, Pack of 6 are designed for precision liquid handling in laboratory settings. Kimble/Kontes, a trusted name in scientific glassware, delivers these pipets as a tool for accurate and repeatable measurements, crucial in various scientific disciplines.
My journey to these pipets stemmed from a need for highly accurate and reusable measuring tools in a remote field lab setup. Traditional plastic pipettes often lack the precision and durability required for repeated use in harsh outdoor environments. I needed something that could withstand rigorous cleaning and deliver consistent results, even when exposed to fluctuating temperatures and humidity.
Upon unboxing, the KIMAX pipets immediately exude quality. The borosilicate glass feels robust, and the color-coding is sharp and clear, a significant upgrade from faded markings on disposable alternatives. The pipets felt well-balanced in my hand, inspiring confidence that a steady hand could easily deliver consistent volumes.
Compared to disposable plastic pipettes and even some lower-grade glass options, the Kimble/Kontes KIMAX pipets stand out in several ways. Disposable pipettes introduce potential environmental concerns and lack the precision for critical measurements. Cheaper glass pipettes may lack the Class A certification, indicating a lower tolerance for accuracy and potential variations in internal diameter.
My initial impression was one of cautious optimism. The price tag of $433.99 for a pack of six is considerable, but the promise of Class A accuracy and reusability piqued my interest. The real test would be in the field, assessing their performance under challenging conditions.
Real-World Testing: Putting Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class A, Color-Coded 37025 1110, Pack of 6 to the Test
First Use Experience
I tested these pipets during water quality analysis at a remote stream-side location. The conditions were typical for the Pacific Northwest: damp, with fluctuating temperatures and occasional light rain. Precision was crucial for accurately measuring reagent volumes needed for titration tests.
The Kimble/Kontes pipets performed exceptionally well, even in the less-than-ideal field setting. The clear markings and fine tip allowed for precise meniscus readings, minimizing errors. I was able to consistently dispense the correct volume of titrant, even with slightly shaky hands.
These pipets required a slight adjustment compared to using disposable plastic pipettes. The glass surface requires care to avoid chipping or breakage, and a gentle touch is required for precise dispensing. After a few practice runs, I quickly became accustomed to their unique feel and handling characteristics.
The only initial issue was a minor one: static cling on the glass surface attracted dust particles, particularly in the dry tent environment. A quick wipe with a lint-free cloth resolved the problem. Otherwise, the KIMAX pipets proved to be reliable and accurate from the outset.
Extended Use & Reliability
After several months of use, these pipets have proven to be a valuable asset to my field work. They have retained their accuracy and show no signs of degradation. They are consistently used multiple times a week.
The borosilicate glass has proven surprisingly durable, withstanding accidental bumps and scrapes without chipping or cracking. Even after repeated cleaning cycles with strong detergents, the graduation markings remain clear and legible. The red band color is still vibrant.
Cleaning these pipets is straightforward. A thorough rinse with distilled water followed by air drying is usually sufficient. For more stubborn residue, a mild detergent solution and a specialized pipette brush work wonders.
Compared to my previous experiences with lower-grade glass pipettes, the Kimble/Kontes KIMAX pipets provide a significantly more reliable and consistent performance. The accuracy and durability are far superior, justifying the higher initial cost. They have significantly reduced measurement errors.
