Let’s Dive into Kimble/Kontes KIMAX Brand Iodine Flasks with ST PTFE Stopper 27200 125, Pack of 2
The Kimble/Kontes KIMAX Brand Iodine Flasks with ST PTFE Stopper 27200 125, Pack of 2 might seem like an unusual item for an outdoor and tactical gear specialist to review, but trust me, understanding analytical processes is crucial in many fields, from water testing in survival situations to analyzing fuel purity for long expeditions. These flasks are designed for precise chemical analysis, specifically for determining iodine values, a critical aspect in assessing the quality of oils, fats, and varnishes – knowledge that can be surprisingly relevant in remote environments when dealing with resources. The PTFE stopper, a key feature, ensures an airtight seal, preventing loss of volatile iodine.
My interest in these flasks stemmed from a need for reliable and accurate analytical tools for a wilderness skills training program I run. We teach advanced skills like rendering animal fats for pemmican and creating natural varnishes for waterproofing gear, and understanding the quality of our ingredients is paramount. I was searching for flasks that could provide repeatable and accurate results, and the Kimble/Kontes name, known for quality labware, caught my eye.
The Kimble/Kontes KIMAX Brand Iodine Flasks arrived securely packaged, each flask nestled in its own protective cardboard divider within the box. My initial impression was one of quality; the glass was thick and clear, and the PTFE stoppers fit snugly and securely. They felt substantial and well-made, a stark contrast to some of the cheaper, flimsy glassware I’ve encountered in the past.
Compared to generic Erlenmeyer flasks with standard rubber stoppers, the KIMAX flasks offer a significant advantage in terms of chemical resistance and seal integrity. While a standard flask might suffice for simple mixing, the iodine analysis requires a completely airtight environment, something a rubber stopper cannot guarantee over extended periods. The precision and reliability offered by Kimble/Kontes are simply unmatched by cheaper alternatives. I was definitely excited to put these to the test, as I knew they could elevate our training program to a new level of scientific rigor.
Real-World Testing: Putting Kimble/Kontes KIMAX Brand Iodine Flasks with ST PTFE Stopper 27200 125, Pack of 2 to the Test
First Use Experience
My first experience with the Kimble/Kontes KIMAX Brand Iodine Flasks was during a workshop on rendering fats for long-term storage, part of our wilderness skills training program. We needed to determine the iodine value of various rendered animal fats to assess their stability and suitability for different uses. The flasks were used in a controlled environment initially, but simulating field conditions.
The procedure involved mixing the fat sample with Rosenmund-Kuhnhenn reagent and titrating with sodium thiosulfate. The flasks performed flawlessly, maintaining an airtight seal throughout the process, crucial for accurate results. Their shape made swirling the contents easy and efficient. There were no unexpected issues; the flasks performed exactly as intended, giving us consistent and reliable readings.
Extended Use & Reliability
After several weeks of intermittent use, the Kimble/Kontes KIMAX Brand Iodine Flasks have proven to be incredibly durable. Despite repeated use and cleaning, there are no signs of etching or clouding of the glass. The PTFE stoppers continue to provide a perfect seal.
Maintaining these flasks is straightforward. A simple wash with soap and water is usually sufficient, but for more stubborn residues, a mild laboratory detergent is effective. Compared to the occasional cracking and deterioration I’ve experienced with other glassware, these flasks have been remarkably robust. They have exceeded my expectations in terms of both performance and longevity.
Breaking Down the Features of Kimble/Kontes KIMAX Brand Iodine Flasks with ST PTFE Stopper 27200 125, Pack of 2
Specifications
- Capacity: 125 mL. This volume is ideal for micro-scale iodine value determinations, reducing reagent consumption and waste.
- Kimble* No.: 27200 125. This is the manufacturer’s specific product identifier, ensuring you receive the correct item.
- Unit: Pack of 2. Having two flasks allows for duplicate analyses, improving the reliability of the results.
- Stopper: ST 22 PTFE. The PTFE stopper provides a chemically inert and airtight seal, critical for preventing iodine loss.
