Let’s Dive into Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 250
The Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 250 is a precision instrument designed for accurate liquid dispensing. Manufactured by Kimble Chase, this buret features a 250mL capacity, 1mL graduations, and a straight bore PTFE stopcock for smooth and controlled dispensing.
My work often demands precise measurements of liquids, particularly in situations where environmental factors could compromise accuracy. Traditional beakers and graduated cylinders simply weren’t cutting it. I needed a reliable, repeatable, and highly accurate dispensing method, leading me to explore high-quality burets.
The Kimble/Kontes KIMAX Dispensing Buret arrived well-packaged, showcasing its delicate glass construction. Immediately, I noticed the robust build quality and the clearly marked, durable white ceramic enamel graduation scale. Its dimensions were as expected, and the PTFE stopcock felt exceptionally smooth in operation.
I considered other options, like automatic burets or digital dispensers, but they came with significantly higher price tags and potential electronic failure points. I also briefly explored less expensive burets from other manufacturers, but the risk of inaccurate measurements and fragile construction was too high. The Kimble/Kontes model offered a balance of precision, reliability, and ease of use that the others simply couldn’t match.
My first impression was one of cautious optimism; I was eager to put it to the test but also acutely aware of the fragility inherent in laboratory glassware. I was particularly impressed with the smooth action of the PTFE stopcock, hinting at the precision engineering involved.
Real-World Testing: Putting Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 250 to the Test
First Use Experience
I primarily tested the Kimble/Kontes KIMAX Dispensing Buret in a controlled laboratory environment. The testing involved dispensing various solutions with known concentrations in several titration experiments.
The buret performed flawlessly, even with viscous liquids; the PTFE stopcock provided exceptionally fine control over the flow rate. The clear graduations made it easy to read and accurately dispense the desired volume of liquid.
The buret required a slight learning curve initially, mainly to master the fine control of the stopcock for drop-wise dispensing. However, after a few practice runs, it became intuitive. There were no immediate issues, although I did note the importance of secure clamping to prevent accidental breakage.
Extended Use & Reliability
After several weeks of regular use, the Kimble/Kontes KIMAX Dispensing Buret has proven to be remarkably reliable. The graduations remain clear and easily readable, and the PTFE stopcock continues to operate smoothly without any signs of leakage.
The KIMAX glass is surprisingly durable; it has withstood repeated cleaning and handling without any chips or cracks. Maintenance is simple; thorough cleaning with appropriate laboratory detergents is all that’s required.
Compared to my previous experience with less precise dispensing methods, the Kimble/Kontes KIMAX Dispensing Buret is a significant improvement. The accuracy and repeatability it provides are invaluable, greatly enhancing the reliability of my experimental results.
Breaking Down the Features of Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 250
Specifications
- Capacity: 250 mL – This large capacity is suitable for experiments requiring larger volumes of titrant.
