My Experience with the Kimble/Kontes KIMAX Volumetric Flask with ST Glass Stopper, Class A, to Contain and Deliver, Kimble Chase 28026 100: Here’s the Truth
The Kimble/Kontes KIMAX Volumetric Flask with ST Glass Stopper, Class A, to Contain and Deliver, Kimble Chase 28026 100 might seem like an ordinary piece of lab equipment to the uninitiated. However, to those in the know, particularly in fields requiring precise measurements, it’s a cornerstone of accurate and reliable work. This flask, produced by Kimble Chase, promises Class A accuracy for both containing and delivering liquids, a crucial attribute for any serious analytical endeavor.
My journey with volumetric flasks began over a decade ago, while working in environmental testing. The accuracy of our results directly impacted regulatory compliance and, more importantly, public health. Sloppy measurements were simply not an option, forcing a relentless search for reliable tools. The Kimble/Kontes KIMAX Volumetric Flask became a staple in our lab after a rigorous vetting process.
Upon unboxing, the first thing that struck me was the quality of the glass. It felt substantial, not fragile, which is a huge plus in a busy lab environment. The ground glass stopper fit snugly, promising a tight seal. Compared to cheaper alternatives we’d previously used – those with ill-fitting stoppers and questionable graduation marks – the KIMAX flask exuded quality.
We considered other options like Pyrex volumetric flasks and some lesser-known brands marketed on price alone. However, Kimble Chase’s reputation for precision glassware and the Class A certification ultimately swayed our decision. First impressions were overwhelmingly positive. I was eager to put this flask through its paces and see if it lived up to the hype.
Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flask with ST Glass Stopper, Class A, to Contain and Deliver, Kimble Chase 28026 100 to the Test
First Use Experience
My first use of the Kimble/Kontes KIMAX Volumetric Flask was in preparing standard solutions for water quality analysis. I needed precise concentrations of various chemicals to calibrate our instruments. The flask’s narrow neck and clear graduation mark made it easy to fill to the exact volume.
The flask performed flawlessly. I experienced no leaks around the stopper during mixing. The solution prepared with the KIMAX flask produced calibration curves that were noticeably more consistent and accurate than those using our older, less precise flasks.
Extended Use & Reliability
After months of consistent use, the Kimble/Kontes KIMAX Volumetric Flask has proven to be incredibly durable. The glass hasn’t chipped or cracked, despite regular handling and washing. The graduation mark remains sharp and clear, even after repeated exposure to harsh chemicals.
Cleaning is straightforward. A mild detergent and a flask brush are all that’s needed to remove residue. Compared to some of our plastic volumetric flasks, the glass KIMAX flask doesn’t retain odors or stains, ensuring accurate measurements every time. It has consistently outperformed cheaper flasks, maintaining its accuracy and reliability over time.
Breaking Down the Features of Kimble/Kontes KIMAX Volumetric Flask with ST Glass Stopper, Class A, to Contain and Deliver, Kimble Chase 28026 100
Specifications
The Kimble/Kontes KIMAX Volumetric Flask with ST Glass Stopper, Class A, to Contain and Deliver, Kimble Chase 28026 100 boasts several key specifications. Its capacity is 100mL. It features a Class A certification, indicating extremely high accuracy.
The flask is calibrated to contain (TC) and to deliver (TD), meaning it’s accurate whether you’re measuring the volume of liquid contained within the flask or the volume dispensed from it. It features a standard taper (ST) ground glass stopper (size 13) that provides a secure, leak-proof seal. The tolerance for the contain line is ±0.08mL, while the deliver line tolerance is ±0.15mL. These tight tolerances ensure accurate measurements. It is designed to meet ASTM Specification E288, Class A unserialized requirements, further guaranteeing quality and consistency.
Performance & Functionality
The Kimble/Kontes KIMAX Volumetric Flask excels in its primary function: precise volume measurement. The flask’s narrow neck minimizes meniscus error, allowing for highly accurate readings. Its Class A certification assures users that the stated volume is accurate within the specified tolerance limits.
A key strength is its versatility. It is suitable for a wide range of laboratory applications, from preparing standard solutions to diluting samples. The only improvement I could suggest would be to include a small, flared base for added stability on uneven surfaces.
Design & Ergonomics
The build quality of the Kimble/Kontes KIMAX Volumetric Flask is exceptional. The KIMAX borosilicate glass is resistant to thermal shock and chemical corrosion. Its weight feels balanced in hand. The ground glass stopper fits perfectly, providing a smooth, leak-proof seal without being overly tight.
The flask is remarkably user-friendly. The clear graduation mark and narrow neck make it easy to achieve accurate volume measurements. No specialized training is needed to use it effectively.
Durability & Maintenance
With proper care, the Kimble/Kontes KIMAX Volumetric Flask should last for years. The robust borosilicate glass construction resists cracking and chipping. It is simple to clean, requiring only soap and water or a suitable laboratory detergent.
Avoid abrasive cleaners, as these can scratch the glass and potentially alter the graduation mark. Regular inspection for chips or cracks is recommended to ensure continued accuracy and safety.
Accessories and Customization Options
The Kimble/Kontes KIMAX Volumetric Flask comes with a standard taper ground glass stopper. There aren’t many customization options for volumetric flasks, as their design is specifically tailored for accurate measurements. However, replacement stoppers are readily available should one become damaged or lost.
While not a direct customization, different size flasks are available within the KIMAX line, allowing labs to choose the appropriate volume for their specific needs. It’s also compatible with various flask brushes and cleaning solutions commonly used in laboratories.
