How the Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 110 Changed My Routine
The Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 110 aren’t exactly the kind of gear I usually review; my expertise leans towards the rugged, the tactical, the “what keeps you alive in the wilderness” kind of stuff. But even in survival, understanding the microscopic world and ensuring water purity is paramount. These aren’t your typical camping tools, but they represent a crucial aspect of preparedness often overlooked: microbiological testing.
What drove me to these specific pipets was a need for precise liquid handling during some recent water quality experiments I was running in a remote field lab setting. I needed something that could handle the rigors of field work, be easily cleaned and reused, and offer accurate measurements. I was looking for reliability over all else.
My first impression upon unboxing was one of simple, functional quality. These aren’t fancy, but the Kimble Chase glass feels robust, and the color-coding is immediately useful. The pipets feel well-made, not delicate or flimsy like some cheaper alternatives.
I considered several other options, including plastic disposable pipettes and even some electronic pipetting devices. However, I ultimately chose the Kimble/Kontes KIMAX Reusable Bacteriological Pipets for their reusability (reducing waste in a sensitive environment), the inherent accuracy of glass, and their ability to withstand repeated sterilization. I wanted something dependable, not another piece of plastic destined for a landfill after one use.
Honestly, I was a little surprised by the simplicity, but also reassured. No batteries to die, no complex mechanisms to fail – just good old-fashioned glass science. I was excited to finally have a reliable method for precise measurements in the field.
Real-World Testing: Putting Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 110 to the Test
First Use Experience
My initial testing took place in a makeshift lab at a remote campsite during a water quality assessment project. I used the Kimble/Kontes KIMAX Reusable Bacteriological Pipets to measure specific volumes of water samples for culturing bacteria and testing for contaminants. I tested various water sources, including a nearby stream, a collected rainwater sample, and water from a spring.
The pipets performed admirably even in somewhat challenging conditions. The color-coding made it easy to quickly identify the correct size (11mL in this case), even when working under less-than-ideal lighting. Filling and dispensing were straightforward, though I did have to refine my technique a bit to achieve optimal accuracy with the blowout method.
The only minor issue I encountered was a slight difficulty in cleaning the pipets thoroughly in the field without access to specialized lab equipment. Ensuring complete sterilization between samples required extra care and attention.
Extended Use & Reliability
After several weeks of consistent use, the Kimble/Kontes KIMAX Reusable Bacteriological Pipets have held up remarkably well. There are no signs of wear and tear, even after repeated washings and sterilizations. The brown stain scale remains clear and easy to read, showing no signs of fading.
Cleaning is relatively easy. A good scrub with a bottle brush and lab-grade detergent, followed by thorough rinsing and autoclaving, keeps them in perfect condition. I’ve found that investing in a proper pipet washer helps streamline the cleaning process and ensures even greater cleanliness.
Compared to my previous experiences with disposable plastic pipettes, these are a game-changer. The glass construction provides far more consistent and accurate measurements, and the reusability dramatically reduces waste and long-term costs. They have exceeded my expectations.
