What I Found Using the Kimble/Kontes KIMAX GL45 Media/Storage Bottles, Graduated, Kimble Chase 14395 250 Media Bottles With Blue Cap
The Kimble/Kontes KIMAX GL45 Media/Storage Bottles, Graduated, Kimble Chase 14395 250 Media Bottles With Blue Cap promises reliable and versatile storage for liquids in laboratory settings. With its durable borosilicate glass construction and autoclavable blue cap, it seemed like the perfect solution for my media preparation needs. My initial impression was that they were very expensive but the product description suggests they are a good value.
My work in developing field-deployable water testing kits requires sterile storage containers that can withstand extreme conditions. I needed bottles that could reliably hold prepared media, survive transport in rough terrain, and maintain sterility throughout the duration of testing. I’d been struggling with cheaper plastic bottles that often leaked or degraded with repeated autoclaving.
The Kimble/Kontes KIMAX GL45 Media/Storage Bottles arrived securely packaged. Upon opening the box, I was immediately impressed by the clarity and heft of the glass. The blue polypropylene caps felt robust, and the graduations were clearly marked.
I had previously used Pyrex bottles and some generic glass bottles from another supplier. The Kimble/Kontes bottles felt sturdier than the Pyrex and the graduations were more accurate than the generic brands. I chose the Kimble/Kontes bottles primarily for their renowned glass quality and the autoclavable cap, crucial for my sterile media storage.
My first impression was one of cautious optimism. The bottles appeared to be well-made and exactly what I needed, but the high price point made me wonder if they would truly justify the cost through superior performance and longevity.
Real-World Testing: Putting Kimble/Kontes KIMAX GL45 Media/Storage Bottles, Graduated, Kimble Chase 14395 250 Media Bottles With Blue Cap to the Test
First Use Experience
I tested the Kimble/Kontes KIMAX GL45 Media/Storage Bottles in my lab during a large-scale media preparation for an upcoming field test. I used them to store sterile nutrient broth and distilled water. They were subjected to autoclaving at 121°C for 20 minutes to ensure sterility.
The bottles performed flawlessly. The blue caps remained tightly sealed during autoclaving, preventing any leakage or contamination. The graduated markings were invaluable for accurate dispensing of media.
There were no issues or surprises. The bottles were easy to fill, easy to handle (even when hot), and the clear graduations made accurate volume measurement effortless.
Extended Use & Reliability
After several weeks of repeated use, including multiple autoclaving cycles, the Kimble/Kontes KIMAX GL45 Media/Storage Bottles have held up exceptionally well. There are no signs of wear and tear, such as clouding of the glass or cracking of the caps.
The glass remains crystal clear, and the graduations are still easy to read. Cleaning is a breeze, and the wide-mouth opening makes it easy to scrub the inside of the bottle thoroughly.
Compared to the plastic bottles I previously used, the Kimble/Kontes bottles are far superior in terms of durability and reliability. The plastic bottles often became brittle and cracked after a few autoclave cycles, rendering them useless. The Kimble/Kontes bottles have proven to be a worthwhile investment, offering long-term performance and peace of mind.
