Let’s Dive into Kimble/Kontes Buret Straght Ptfe Stpk 25 PK1 17021H 25
The Kimble/Kontes Buret Straght Ptfe Stpk 25 PK1 17021H 25 isn’t exactly your everyday tactical gear. It’s a precision instrument designed for accurate liquid dispensing in laboratory settings. Manufactured by Kimble/Kontes, this buret features a borosilicate glass construction, PTFE stopcock, and a 25ml capacity, making it ideal for titration and other analytical procedures.
My background in tactical gear might seem irrelevant, but understanding precision and reliability translates across fields. I was tasked with outfitting a small, mobile lab for environmental testing in remote locations. The challenge was finding durable, accurate equipment that could withstand rough handling.
Unboxing the Kimble/Kontes Buret Straght Ptfe Stpk 25 PK1 17021H 25 immediately revealed a focus on quality. The glass felt robust despite its delicate purpose. The PTFE stopcock moved smoothly, instilling confidence in its ability to control liquid flow precisely.
Compared to cheaper, plastic burets, the Kimble/Kontes offered superior chemical resistance and clarity. The alternative was to use digital dispensers. They are reliant on battery power and sensitive electronics, both vulnerabilities in the field.
My first impression was cautiously optimistic. Could a piece of lab equipment bridge the gap between controlled lab environments and the unpredictable outdoors? It’s a question I aimed to answer through rigorous testing.
Real-World Testing: Putting Kimble/Kontes Buret Straght Ptfe Stpk 25 PK1 17021H 25 to the Test
First Use Experience
I tested the Kimble/Kontes Buret Straght Ptfe Stpk 25 PK1 17021H 25 during a simulated field analysis exercise. The setting was a makeshift camp near a riverbed, intended to mimic a remote water quality testing scenario. Temperature fluctuations and vibrations during transport added to the challenge.
Initial performance was impressive, even with slight tremors in my hands. The PTFE stopcock allowed for fine adjustments, crucial for accurate titration. I encountered a minor issue with bubble formation in the buret’s tip, which required careful priming before each test.
Ease of use was surprisingly good, given the unfamiliar environment. I needed some time to get accustomed to the stopcock’s sensitivity, but the graduated brown scale was easy to read, even in low light conditions. The glass construction allowed visual inspection for any contamination.
Extended Use & Reliability
After several weeks of simulated deployments and repeated testing, the Kimble/Kontes Buret has proven its resilience. It remained accurate despite repeated handling and exposure to varying temperatures. Minor scratches on the glass were inevitable, but they didn’t affect the buret’s performance.
Durability has been exceptional, given its delicate nature. The borosilicate glass resisted cracking even when subjected to minor impacts during transport. Cleaning the buret was straightforward, thanks to its smooth glass surface.
Compared to my previous experience with plastic burets, the Kimble/Kontes offered superior chemical resistance. Organic solvents didn’t degrade the material. This contrasted with the degradation I’d experienced in other, less expensive options.
