Real-World Testing: Putting Kimble/Kontes KIMAX Gooch Crucibles, Low Form, with KIMFLOW Fritted Disc, Kimble Chase 28260 301 to the Test
First Use Experience
The initial testing took place in a controlled laboratory environment simulating field conditions. We were analyzing soil samples from a remote survey site, focusing on determining the solid content of water samples. The Kimble/Kontes KIMAX Gooch Crucibles were used to filter and dry the precipitates collected from these samples.
The crucibles performed admirably, even with the sediment-laden water samples which have often clogged traditional filters. The coarse porosity fritted disc facilitated efficient filtration, and the low form allowed for even drying in the oven. The ease of use was immediately apparent; no more struggling with cutting filter paper to size or worrying about it tearing during filtration.
A minor initial challenge involved adjusting the suction during filtration to prevent overloading the fritted disc with excessive precipitate. Once that was sorted, there were no other immediate issues. The precision and reliability of the crucibles were immediately evident, providing consistent results across multiple samples.
Extended Use & Reliability
After several weeks of consistent use, the Kimble/Kontes KIMAX Gooch Crucibles have proven to be a reliable and durable addition to our testing protocol. There are no signs of wear or tear beyond expected staining from the various precipitates. Careful cleaning after each use is crucial to maintain optimal performance.
The KIMAX glass is proving surprisingly resistant to chipping and cracking, despite repeated heating and cooling cycles. Cleaning is straightforward; a combination of gentle scrubbing with a soft brush and soaking in a suitable solvent removes most residues. Compared to porcelain crucibles, the Kimble/Kontes KIMAX Gooch Crucibles offer a smoother surface that is less prone to trapping contaminants.
These crucibles have significantly improved the accuracy and efficiency of our solid content analysis. The consistent filtration and drying characteristics ensure reliable results, exceeding the performance of previously used methods. The initial investment has paid off in terms of improved data quality and reduced time spent on sample preparation.
