Let’s Dive into Kimble/Kontes Buret Clasa Ptfe Stpk 5ML CS1 17110F 5
The Kimble/Kontes Buret Clasa Ptfe Stpk 5ML CS1 17110F 5 is a specialized piece of laboratory equipment designed for precise liquid dispensing. Manufactured by Kimble/Kontes, this burette distinguishes itself with its PTFE (Polytetrafluoroethylene) stopcock, known for its chemical resistance and smooth operation. Its 5mL capacity makes it ideal for titrations and other analytical procedures requiring accuracy on a smaller scale.
My need for a burette stemmed from an increasing demand for precise liquid handling in various field tests I was conducting. Specifically, I needed to accurately dispense reagents for soil analysis in remote locations, where traditional lab setups were unavailable. I was drawn to the Kimble/Kontes model because of the promise of a durable, chemically inert stopcock, crucial for withstanding harsh field conditions.
The Kimble/Kontes Buret Clasa Ptfe Stpk 5ML CS1 17110F 5 arrived well-packaged, assuring no damage during shipping. My initial impression was that it was smaller than I anticipated. The borosilicate glass appeared to be of good quality, and the PTFE stopcock felt remarkably smooth to operate.
Compared to other burettes I’ve used, notably those with glass stopcocks, the PTFE material immediately stood out. Burettes with glass stopcocks were often prone to sticking, especially with alkaline solutions, something I hoped the Kimble/Kontes model would eliminate. The difference in price was a factor, but the long-term value of reliability and chemical resistance seemed worth the investment.
I was excited about the potential for increased precision and reduced maintenance with the Kimble/Kontes Buret Clasa Ptfe Stpk 5ML CS1 17110F 5. My initial impression was very positive. The size seemed well-suited to the volume I typically needed for field testing.
Real-World Testing: Putting Kimble/Kontes Buret Clasa Ptfe Stpk 5ML CS1 17110F 5 to the Test
First Use Experience
I first tested the Kimble/Kontes Buret Clasa Ptfe Stpk 5ML CS1 17110F 5 in a series of soil pH tests in a remote agricultural area. The environment was dusty and exposed to fluctuating temperatures. The burette was used to dispense a standardized base solution for titration against soil samples.
The PTFE stopcock proved its worth immediately. Even with fine sediment settling around it, the stopcock remained smooth and responsive. Achieving dropwise addition was remarkably easy, crucial for accurate endpoint determination.
The burette was straightforward to use, though the small 5mL volume required a bit of care to avoid overfilling during the initial setup. I quickly adapted to the graduated scale. No significant issues arose during the first field tests, a pleasant surprise considering the challenging conditions.
Extended Use & Reliability
After several months of frequent use, the Kimble/Kontes Buret Clasa Ptfe Stpk 5ML CS1 17110F 5 has held up remarkably well. The borosilicate glass remains clear, and the graduations are still easily readable. There are no signs of chemical attack on the glass or the PTFE stopcock.
Durability has been excellent. Despite being transported in a protective case, the burette has occasionally experienced minor bumps and vibrations, but it has shown no signs of cracking or weakening. The PTFE stopcock still operates smoothly.
Maintenance involves rinsing the burette with distilled water after each use and occasionally cleaning the stopcock with a mild detergent. The process is quick and simple, ensuring minimal downtime during field testing. Compared to my previous experiences with glass stopcock burettes, the Kimble/Kontes model is far more reliable and requires significantly less maintenance.
