Kimble/Kontes Flask Clasa Wd Mouth 50ML PK1 28014W 50 Review

Going All In on the Kimble/Kontes Flask Clasa Wd Mouth 50ML PK1 28014W 50

The Kimble/Kontes Flask Clasa Wd Mouth 50ML PK1 28014W 50 isn’t your everyday tactical gadget, but it’s a vital piece of equipment for those in specific fields. This volumetric flask, manufactured by Kimble/Kontes, is designed for precise measurement and comes with a wide mouth for easy access. It’s a Class A flask, meaning it meets stringent accuracy standards, and includes a glass stopper.

My need for such a flask stemmed from my work analyzing soil samples in remote locations after potential CBRN (Chemical, Biological, Radiological, Nuclear) incidents. I needed a reliable, accurate, and easy-to-handle container for preparing reagents in the field.

Unboxing the Kimble/Kontes Flask Clasa Wd Mouth 50ML PK1 28014W 50, I was immediately struck by the quality of the glass. It felt sturdy, and the wide mouth was indeed significantly larger than standard flasks, making it much easier to pour liquids without spillage. The ground glass stopper fit snugly, ensuring a good seal.

Compared to a standard Erlenmeyer flask or a generic graduated cylinder, the Kimble/Kontes Flask offers superior accuracy for precise measurements. While beakers are useful for general mixing, they lack the calibration needed for critical work. I chose this particular flask for its Class A certification and the convenience of the wide mouth, which minimizes reagent loss during preparation.

My initial impression was one of cautious optimism. The quality was evident, but its real value would lie in its performance under field conditions. I was eager to see if it would live up to its precision rating.


Real-World Testing: Putting Kimble/Kontes Flask Clasa Wd Mouth 50ML PK1 28014W 50 to the Test

First Use Experience

My first field test with the Kimble/Kontes Flask Clasa Wd Mouth 50ML PK1 28014W 50 involved preparing a titration solution for analyzing soil pH at a simulated contamination site. I used it within a mobile lab setup inside a modified Humvee. The conditions were challenging, with bumpy terrain and fluctuating temperatures inside the vehicle.

Despite the instability, the wide mouth made it easy to pour the concentrated acid into the flask without spillage, something I had struggled with using narrower-necked flasks. The flask performed admirably, maintaining its integrity even with the jostling. No issues arose during the initial use; the glass stopper remained secure, preventing any leaks.

Extended Use & Reliability

After several weeks of consistent use in various field scenarios, the Kimble/Kontes Flask Clasa Wd Mouth 50ML PK1 28014W 50 has proven to be a reliable tool. I’ve used it for preparing various solutions, from indicators to complex reagents, and its accuracy remains consistent.

Durability has been impressive; despite being glass, it has withstood minor bumps and accidental knocks without cracking. Cleaning is relatively easy, though care is required due to the glass construction. Compared to previous plastic volumetric flasks, the Kimble/Kontes Flask maintains its calibration far better and doesn’t degrade with repeated exposure to solvents.
