Real-World Testing: Putting Kimble/Kontes Buret No Stpk 50 Ml CS1 17026G 50 to the Test
First Use Experience
I initially tested the Kimble/Kontes Buret No Stpk 50 Ml CS1 17026G 50 in a controlled laboratory setting to establish a baseline. This familiar environment allowed me to focus solely on the buret’s performance. The primary task was to perform a series of titrations, comparing the results against those obtained with a calibrated digital titrator.
The buret performed surprisingly well in terms of accuracy, even without a stopcock. Controlling the flow required a different technique than I was accustomed to, involving careful tilting and maneuvering. There was a slight learning curve in mastering the flow control, and the initial runs were a bit uneven.
One immediate issue was the lack of fine control at lower volumes. Achieving precise dropwise addition, crucial for accurate endpoints, proved challenging. Despite this, the overall accuracy was within acceptable limits for Class B glassware.
Extended Use & Reliability
After several weeks of regular use in the lab and a few deployments in a mobile testing unit, the Kimble/Kontes Buret No Stpk 50 Ml CS1 17026G 50 has proven to be more durable than expected. The simple design has held up well to the bumps and jostles of transport. There are no visible signs of wear and tear on the glass itself.
Cleaning the buret is straightforward, requiring only standard laboratory detergents and thorough rinsing. The absence of a stopcock eliminates a potential point of contamination and simplifies the cleaning process. Compared to burets with stopcocks that require disassembly and greasing, this model is significantly easier to maintain.
Compared to my previous experiences with more elaborate burets, the Kimble/Kontes Buret No Stpk 50 Ml CS1 17026G 50 trades some precision for increased robustness and ease of maintenance. While it may not be ideal for extremely precise titrations, its reliability and durability make it well-suited for field applications.
Breaking Down the Features of Kimble/Kontes Buret No Stpk 50 Ml CS1 17026G 50
Specifications
The Kimble/Kontes Buret No Stpk 50 Ml CS1 17026G 50 is a 50 mL Class B buret made from borosilicate glass. Its key feature is the absence of a traditional stopcock, relying instead on controlled tilting for dispensing. The scale is marked with durable black ceramic enamel, providing clear and easy-to-read graduations.
The buret is designed to meet ASTM Specification E287, ensuring compliance with established accuracy standards for Class B glassware. The Kimble/Kontes LUBRI-FLO stopcock barrel is fitted with a size PS 2 PTFE plug in models that include a stopcock, though this model specifically lacks one. A KIM-KAP dust cap is included to prevent contamination.
These specifications are significant because they directly impact the buret’s accuracy, durability, and ease of use. The borosilicate glass offers excellent chemical resistance and thermal stability, crucial for handling various reagents. The Class B accuracy designation means it meets certain precision thresholds but is not intended for applications requiring the highest possible accuracy.
Performance & Functionality
The Kimble/Kontes Buret No Stpk 50 Ml CS1 17026G 50 performs adequately for applications where high precision is not critical. Its accuracy is within the tolerances specified for Class B burets. However, the lack of a stopcock makes fine control of the dispensing rate challenging, especially at low volumes.
The buret’s main strength lies in its simplicity and robustness. The absence of a stopcock eliminates a common point of failure and simplifies maintenance. One notable weakness is the difficulty in achieving precise dropwise addition, which can affect the accuracy of titrations requiring precise endpoints.
Overall, the Kimble/Kontes Buret No Stpk 50 Ml CS1 17026G 50 meets expectations for a Class B buret, providing acceptable accuracy with enhanced durability. It may not be the best choice for highly precise applications, but it is a reliable option for routine analyses and field use.
