Let’s Dive into Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020 50, Pack of 2
As an outdoor and tactical gear specialist, I often find myself applying principles of precision and accuracy to areas outside of traditional ballistics or navigation. Sometimes, that precision bleeds into seemingly unrelated fields, which is how I encountered the Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020 50, Pack of 2. These aren’t your typical survival tools, but in scenarios where absolute accuracy in measurement is critical – think advanced water purification, improvised medicine, or detailed environmental analysis – they can be invaluable.
My interest in these pipets stemmed from a need for precise liquid measurement in advanced survival scenarios. I was developing a course on advanced wilderness medicine and needed a reliable method to measure small quantities of liquids for formulating treatments in the field.
The package arrived well-protected, revealing two Kimble/Kontes pipets crafted from what appeared to be high-quality glass. The color-coding was a thoughtful touch, offering quick visual identification. I noted their surprisingly delicate feel despite the description touting their ruggedness.
I initially considered cheaper plastic alternatives and graduated cylinders, but I chose these pipets for their superior accuracy and chemical resistance. The graduated cylinders lacked the precision I required for minute measurements, and the plastic alternatives raised concerns about leaching chemicals into the solutions.
My first impression was one of cautious optimism. The precision markings and color-coding gave me confidence, but I was also acutely aware of their fragility and the need for careful handling in the field.
Real-World Testing: Putting Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020 50, Pack of 2 to the Test
First Use Experience
I tested the Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020 50, Pack of 2 in a controlled environment first, simulating a wilderness lab setup within my workshop. This allowed me to become familiar with their use and establish a baseline for accuracy. I measured distilled water and various diluted solutions, comparing the results against a calibrated digital scale.
The pipets performed admirably even in low light. Their brown stain markings, permanently fused into the glass, remained easy to read. It took some practice to get used to the aspiration and dispensing technique, ensuring accurate meniscus readings.
The small tip opening, as the description noted, required a slower dispensing rate than I initially anticipated. I learned that patience and a steady hand were key to avoiding overshooting the desired volume.
Initially, I fumbled the aspiration a few times, drawing liquid too quickly and creating air bubbles. However, after a few practice runs, I became proficient in using the pipets to accurately measure various liquids.
Extended Use & Reliability
After several weeks of repeated use, the Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020 50, Pack of 2 have maintained their accuracy and structural integrity. I have used them to measure a wide range of liquids, from water samples to diluted acids and bases.
There are no signs of wear and tear on the glass itself, but I have noticed that the color-coding bands can be scratched if subjected to rough handling. Keeping them protected within a rigid case during transport is essential.
Cleaning the pipets requires care, but it is a straightforward process using soap, water, and a pipet brush. Rinsing them thoroughly with distilled water is vital to avoid contaminating subsequent measurements.
These pipets outperform the plastic alternatives I have used in the past. The superior chemical resistance and accuracy of the glass pipets make them a worthwhile investment for applications requiring precision.
