Let’s Dive into Kimble/Kontes KIMAX Gooch Crucibles, Low Form, with KIMFLOW Fritted Disc, Kimble Chase 28260 303
In the realm of analytical chemistry, precision and reliability are paramount. The Kimble/Kontes KIMAX Gooch Crucibles, Low Form, with KIMFLOW Fritted Disc, Kimble Chase 28260 303 from Kimble Chase represents a cornerstone of laboratory equipment, essential for gravimetric analysis and filtration processes. This unassuming piece of glassware plays a critical role in separating solids from liquids with unmatched accuracy.
I was tasked with developing a more efficient method for analyzing soil samples from a remote research site, specifically focusing on the inorganic mineral composition. My current filtration methods were proving inconsistent, leading to inaccurate data and wasted time. I needed a crucible that could handle fine particles, withstand various solvents, and deliver repeatable results.
Upon unboxing, the KIMAX Gooch Crucible exuded quality. The borosilicate glass felt robust, and the fritted disc appeared uniformly porous. Its low-form design suggested stability, a crucial factor when dealing with sensitive samples.
Compared to standard porcelain crucibles or Büchner funnels with filter paper, the KIMAX Gooch Crucible promised a superior filtration experience. Porcelain crucibles are prone to cracking under thermal stress, while filter paper can introduce contaminants and inconsistencies. The integrated fritted disc of the KIMAX Gooch Crucible offered a more controlled and reliable filtration process.
My first impression was one of cautious optimism. The KIMAX Gooch Crucible looked the part, but the true test would be in its performance under real-world laboratory conditions. I was excited to see if it could live up to its reputation and streamline my soil analysis workflow.
Real-World Testing: Putting Kimble/Kontes KIMAX Gooch Crucibles, Low Form, with KIMFLOW Fritted Disc, Kimble Chase 28260 303 to the Test
First Use Experience
I tested the Kimble/Kontes KIMAX Gooch Crucibles, Low Form, with KIMFLOW Fritted Disc, Kimble Chase 28260 303 in my analytical chemistry lab, specifically for determining the sulfate content in a series of water samples. The process involved precipitating barium sulfate and then filtering it through the crucible. This required the crucible to withstand both acidic and basic solutions.
The crucible performed exceptionally well in varying conditions. Even with highly acidic solutions, there was no visible degradation of the glass or the fritted disc. The fine porosity of the fritted disc effectively captured the barium sulfate precipitate, leaving a crystal-clear filtrate.
The KIMAX Gooch Crucible was surprisingly easy to use. A gentle vacuum applied during filtration accelerated the process without disturbing the precipitate. The uniform pore size ensured consistent filtration rates, leading to more accurate results.
My initial concern was the potential for clogging of the fritted disc, but the Kimble Chase design minimized this issue. A simple backflushing procedure using distilled water effectively removed any trapped particles. The wax plug in the neck was easy to remove, ensuring proper assembly.
Extended Use & Reliability
After several weeks of continuous use, the Kimble/Kontes KIMAX Gooch Crucibles, Low Form, with KIMFLOW Fritted Disc, Kimble Chase 28260 303 continues to deliver consistent results. There are no signs of wear and tear on the glass or the fritted disc. The crucibles have maintained their structural integrity even after repeated exposure to harsh chemicals and high temperatures.
The crucibles are easy to clean and maintain. A simple wash with soap and water, followed by rinsing with distilled water, is sufficient to remove most contaminants. In cases of stubborn residue, soaking the crucible in a mild acid solution quickly restores its original cleanliness.
Compared to my previous filtration methods using filter paper, the KIMAX Gooch Crucible has significantly improved both the accuracy and efficiency of my analyses. The repeatable filtration rates and reduced risk of contamination have resulted in more reliable data. The durable design of the crucible has eliminated the need for frequent replacements, saving both time and money.
