Let’s Dive into Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Polyethylene Stopper, Class A 28014P 100, Pack of 6
The Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Polyethylene Stopper, Class A 28014P 100, Pack of 6 represent a cornerstone of accurate liquid measurement in any laboratory setting. These flasks, manufactured by Kimble/Kontes, are calibrated to contain a precise volume of 100mL, ensuring reliability for critical experiments and analyses. The inclusion of a standard taper (ST) polyethylene stopper safeguards the contents, minimizing evaporation and contamination.
My journey to acquiring these flasks stemmed from a need for highly accurate volumetric measurements in a small-scale water quality testing project I was running for a local conservation group. Cheaper alternatives simply couldn’t provide the Class A precision required for reliable results. The pack of six offered a practical quantity for running multiple samples simultaneously.
Upon unboxing, I was immediately struck by the quality of the glass. Each flask felt substantial yet delicate, reflecting the meticulous craftsmanship expected from Kimble/Kontes. The graduations were sharp and clear, promising easy and precise readings.
I had considered cheaper volumetric flasks from lesser-known brands, as well as graduated cylinders. Ultimately, the Class A certification and the included polyethylene stoppers of the Kimble/Kontes KIMAX Brand Volumetric Flasks swayed my decision. The accuracy and reliable closure outweighed the cost savings of the alternatives.
My initial impression was one of cautious optimism. I was excited to finally have a set of flasks capable of meeting the stringent demands of my project. But I was also aware that glassware, regardless of quality, requires careful handling to maintain its integrity.
Real-World Testing: Putting Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Polyethylene Stopper, Class A 28014P 100, Pack of 6 to the Test
First Use Experience
I first tested the Kimble/Kontes KIMAX Brand Volumetric Flasks in my makeshift field lab, which is essentially a well-organized shed at our conservation site. The testing involved preparing standard solutions for calibrating water quality testing instruments, a process demanding utmost accuracy. The flasks were used to dilute concentrated stock solutions to create precise working standards.
Despite working in a slightly dusty environment, the polyethylene stoppers provided a secure seal, preventing contamination of the solutions. The wide mouth of the flask made filling and dispensing relatively easy, even with viscous liquids.
The flasks required no break-in period; they were ready to use straight out of the box. However, precise filling to the etched graduation mark required a steady hand and careful attention to avoid overfilling.
My only initial concern was the fragility of the glass. I was extra cautious when handling the flasks to avoid any accidental breakage.
Extended Use & Reliability
After several months of regular use, the Kimble/Kontes KIMAX Brand Volumetric Flasks have proven to be remarkably reliable. They consistently deliver accurate volume measurements, crucial for maintaining the integrity of my water quality data. The graduation marks remain clear and legible, even after repeated cleaning cycles.
Despite being used in a demanding field setting, the flasks have shown no signs of wear and tear, aside from minor superficial scratches. The KIMAX borosilicate glass appears to be more robust than I initially anticipated.
Cleaning the flasks is straightforward. A mild detergent and a soft brush are all that’s needed to remove residue. The polyethylene stoppers are equally easy to clean and have retained their sealing properties.
Compared to previous experiences with cheaper glassware, the Kimble/Kontes KIMAX Brand Volumetric Flasks are a significant upgrade. The accuracy and durability far outweigh the initial investment. The consistency in volume measurements has significantly improved the reliability of my testing results.
