Let’s Dive into Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020-11100, Case of 12
The Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020-11100, Case of 12 represent a seemingly niche product, but in reality, they are foundational tools in countless scientific and industrial processes. Kimble/Kontes, a respected name in laboratory glassware, delivers these pipets with a focus on accuracy, durability, and ease of identification. Their reusability also aligns with modern concerns about sustainability.
My journey to acquiring these pipets stemmed from a peculiar need: formulating precise dilutions of custom-blended scents for wildlife attractants. I needed consistent, repeatable measurements for my experimental formulas, and “eyeballing it” simply wasn’t cutting it. The advertised accuracy and color-coding of the Kimble/Kontes pipets seemed like the perfect solution.
The unboxing experience was straightforward. The pipets arrived securely packaged in a cardboard box, each nestled within individual compartments to prevent breakage. The glass felt substantial, not fragile, and the color bands were clearly defined.
I briefly considered cheaper, disposable plastic pipets, or even graduated cylinders. However, the Kimble/Kontes pipets promised superior accuracy compared to the plastic options, and greater precision than graduated cylinders, especially for small volumes. Furthermore, the idea of generating less waste with reusable glassware appealed to my environmentally conscious side.
My first impression was cautiously optimistic. They seemed like a professional-grade tool, but the price tag of $225.99 gave me pause, hoping they lived up to the hype. Only rigorous testing would determine if they were worth the investment.
Real-World Testing: Putting Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020-11100, Case of 12 to the Test
First Use Experience
My initial testing ground was my makeshift lab, a repurposed corner of my garage. I was formulating a new deer attractant scent, requiring precise measurements of various essential oils and synthetic compounds. The Kimble/Kontes pipets were immediately put to work dispensing 1 mL aliquots.
The pipets performed admirably. The narrow tip allowed for controlled dispensing, and the meniscus was easy to read against a white background. I did find that mastering the proper suction technique with a pipette bulb took a little practice.
There were no significant issues after the first use. The pipets cleaned easily with warm soapy water and a narrow brush. I was careful to avoid any harsh chemicals that might damage the color bands.
Extended Use & Reliability
After several weeks of consistent use, the Kimble/Kontes pipets have proven to be reliable and durable. There are no signs of wear and tear on the glass itself. The color bands remain vibrant and intact.
Cleaning remains relatively easy, although thorough rinsing is crucial to prevent cross-contamination between different scent formulations. I’ve noticed that trace amounts of highly concentrated oils can be difficult to completely remove, requiring multiple washes.
These pipets have significantly improved the consistency and repeatability of my scent formulations, far surpassing my previous attempts with less precise measuring tools. They outperform my initial expectations and have become an indispensable part of my process. They certainly trounce any disposable options I’ve considered.
