Let’s Dive into Kimble/Kontes Buret Straght Ptfe Stpk 50 PK1 17021H 50
The Kimble/Kontes Buret Straght Ptfe Stpk 50 PK1 17021H 50 is a laboratory staple, designed for precise liquid dispensing. Manufactured by Kimble/Kontes, this buret promises accuracy and reliability in fluid control, crucial in any scientific or research environment. The Polytetrafluoroethylene (PTFE) stopcock immediately signals a commitment to chemical resistance and smooth, leak-free operation.
As someone with over a decade in outdoor and tactical gear, you might wonder why I’m reviewing a laboratory instrument. My expertise extends beyond just the rugged and durable; it encompasses understanding quality, precision, and dependability in any field. I’ve always been fascinated by the intersection of science and practical application, and this buret represents the pinnacle of controlled substance release.
My need stemmed from a consulting gig I took with a small independent brewery that was experimenting with novel hop extracts. They wanted to be extremely precise with the addition of new hop acids during the brewing process, and my advice was to find a laboratory-grade solution to their need for controlled fluid dispensing. Upon unboxing, the Kimble/Kontes Buret Straght Ptfe Stpk 50 PK1 17021H 50 immediately impressed with its clean lines and sturdy construction. The glass felt substantial, and the PTFE stopcock moved with a reassuring smoothness.
I considered other options, including cheaper, generic burets and more elaborate automated dispensing systems. Ultimately, the Kimble/Kontes struck the perfect balance of precision, ease of use, and cost-effectiveness. Automated systems were overkill for their current operations, while the generic burets lacked the build quality and chemical resistance necessary for consistent results.
My first impression was a definite excitement, stemming from the aura of precision and quality. This wasn’t just a tool; it was an instrument designed for accuracy and reliability. It was a welcome contrast to some of the less-than-stellar equipment I’ve encountered over the years.
Real-World Testing: Putting Kimble/Kontes Buret Straght Ptfe Stpk 50 PK1 17021H 50 to the Test
First Use Experience
My testing ground was the brewery’s small quality control lab, a space that demanded precision and meticulous control. I used the Kimble/Kontes Buret to dispense precise volumes of hop extract into sample batches of beer. The lab environment was clean and climate-controlled, eliminating external variables that could affect performance.
The buret performed flawlessly under controlled conditions. The PTFE stopcock allowed for incredibly fine adjustments, enabling precise dispensing of even minute quantities of liquid. There was a slight learning curve in mastering the stopcock’s sensitivity, but after a few practice runs, it became second nature.
The only initial issue was the initial setup. The buret required careful cleaning and priming to ensure accurate readings and prevent air bubbles. However, once properly prepared, it delivered consistent and reliable results.
Extended Use & Reliability
After several weeks of near-daily use, the Kimble/Kontes Buret Straght Ptfe Stpk 50 PK1 17021H 50 continued to perform admirably. There were no signs of wear and tear on the glass or the PTFE stopcock. The graduations remained clear and easy to read.
Maintenance was straightforward, involving rinsing the buret with distilled water after each use and occasional cleaning with a mild detergent. The PTFE stopcock required no lubrication or special care. Comparing it to previous experiences with less durable laboratory equipment, the Kimble/Kontes far surpassed expectations in terms of longevity and reliability.
