Everything You Need to Know About the Kimble/Kontes KIMAX Media/Storage Bottles, KG-35 Borosilicate Glass, Graduated, Kimble Chase 61110T 1000 Black Phenolic PTFE-Faced 14-B White Rubber-Lined Closure

The Kimble/Kontes KIMAX Media/Storage Bottles, KG-35 Borosilicate Glass, Graduated, Kimble Chase 61110T 1000 Black Phenolic PTFE-Faced 14-B White Rubber-Lined Closure represents a seemingly simple, yet crucial tool in any laboratory or scientific setting. These aren’t your everyday water bottles; they’re precision-engineered vessels designed for the safe and accurate storage and handling of media and solutions. Kimble/Kontes, a trusted name in labware, delivers a product built to withstand demanding environments, and provides a reliable way to store solutions. Join me as I delve into the world of these bottles, sharing my experiences and insights from over a decade of working with similar equipment.

My work often requires meticulous preparation and storage of various chemical solutions and biological media. Maintaining their integrity and purity is paramount, a challenge many containers fail to meet adequately. I needed a storage solution that was chemically inert, offered precise volume markings, and provided a secure, leak-proof seal to prevent contamination.

Upon receiving the Kimble/Kontes KIMAX Media/Storage Bottle, I was immediately struck by the heft of the KG-35 borosilicate glass. It felt substantial, assuring me of its ability to withstand thermal stress during autoclaving. The graduated markings were crisp and clear, appearing far more precise than those on the generic bottles I had previously used.

Compared to cheaper alternatives made from soda-lime glass, the Kimax bottle felt significantly more robust and chemically resistant. Similarly, plastic bottles, while lighter, often leach chemicals and are unsuitable for long-term storage of sensitive media. This Kimble/Kontes bottle seemed like the perfect balance of durability, chemical inertness, and accuracy, justifying its price point.

My initial impression was one of quiet confidence. This wasn’t just a bottle; it was a purpose-built tool that signaled a commitment to precision and reliability in my work. I was excited to put it through its paces and see if it lived up to the promise of its design and materials.

Real-World Testing: Putting Kimble/Kontes KIMAX Media/Storage Bottles, KG-35 Borosilicate Glass, Graduated, Kimble Chase 61110T 1000 Black Phenolic PTFE-Faced 14-B White Rubber-Lined Closure to the Test

First Use Experience

My first test involved storing a pH-sensitive buffer solution used in protein purification. The bottle was used in a lab setting involving multiple temperature shifts, including overnight refrigeration. The crucial aspect was maintaining the buffer’s pH and preventing any leaching from the container.

Even after multiple temperature cycles and several days of storage, the buffer’s pH remained stable, a testament to the glass’s inertness and the closure’s seal. The graduated markings proved accurate when dispensing aliquots, further simplifying the process. This was a far cry from my experience with other storage solutions.

The bottles were easy to handle, even with gloves, and the wide mouth made filling and dispensing effortless. There were no unexpected issues; the bottle performed exactly as expected, providing a stable and reliable storage environment.

Extended Use & Reliability

After several months of continuous use, including repeated autoclaving cycles for sterilization, the Kimble/Kontes KIMAX Media/Storage Bottle showed no signs of degradation. The glass remained clear, and the graduations didn’t fade. The closure continued to provide a tight seal, preventing any leakage or contamination.

The only sign of wear was some minor discoloration on the white rubber liner of the closure from repeated exposure to certain chemicals, although this did not affect its performance. The bottles are easy to clean using standard lab detergents and brushes. Their consistent performance far exceeded my expectations based on past experiences with lower-quality storage containers.
