Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 1000 Review

The Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 1000: Review from Real Use

The Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 1000 is a large capacity, high-precision piece of laboratory equipment designed for accurate dispensing of liquids. Manufactured by Kimble Chase, these burets are essential for titrations and other quantitative chemical analyses. With a 1000mL capacity and a PTFE stopcock, they promise durability and precise control over liquid flow. The durable white ceramic enamel graduation scale offers easy and accurate readings, making it a critical tool in any lab setting.

I was looking for a reliable large-volume dispensing solution for preparing custom solutions for long-term environmental monitoring projects. I needed a burette that could handle a substantial volume and maintain consistent accuracy over extended use.

Upon unboxing, the first thing I noticed was the robust construction of the KIMAX glass. It felt solid and capable of withstanding regular laboratory use, and the PTFE stopcock turned smoothly and felt very precise. Compared to cheaper alternatives with glass stopcocks, the PTFE promised reduced sticking and no need for constant greasing, a big selling point for my intended application.

I considered several options, including a cheaper no-name brand and a digital burette. I ultimately chose the Kimble/Kontes model for its reputation for accuracy and the reliability of its manual operation. Digital burettes can be finicky and prone to electronic failures in harsh lab environments, making a manual option more appealing. My initial excitement stemmed from the potential time savings and accuracy this burette offered compared to using graduated cylinders for large-volume dispensing.

Real-World Testing: Putting Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 1000 to the Test

First Use Experience

I initially tested the Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 1000 in my lab to prepare large batches of calibration standards. The controlled dispensing was a significant improvement over pouring from large bottles. Filling was easy thanks to the wide opening, and the PTFE stopcock allowed for very fine adjustments to the flow rate.

I tested it under varying humidity levels in the lab. Even in slightly humid conditions, the PTFE stopcock maintained its smooth operation without sticking, confirming its reliable performance. The burette was quite straightforward to use, though it did require some practice to achieve consistent drop-by-drop dispensing. After a few runs, I was able to confidently and accurately dispense the desired volumes.

My only initial issue was the height of the burette; its 780mm length made it somewhat unwieldy to handle and store. Securing the burette safely while dispensing was crucial to prevent accidental spills or breakage.

Extended Use & Reliability

After several weeks of regular use, the Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 1000 has proven to be a reliable workhorse. The glass remains clear, and the graduations are still perfectly legible.

There have been no signs of wear and tear beyond minor scratches from handling. Cleaning is relatively easy, though the length requires a specialized burette brush. Comparing it to my previous experience with less precise dispensing methods, this burette has significantly improved the consistency and accuracy of my solutions. It definitely outperforms graduated cylinders when dealing with larger volumes, and it avoids the electronic issues that can plague digital dispensers.
