What Makes the Kimble/Kontes KIMAX Gooch Crucibles, Low Form, with KIMFLOW Fritted Disc, Kimble Chase 28260 152 Click?
In the world of laboratory filtration, precision and reliability are paramount. The Kimble/Kontes KIMAX Gooch Crucibles, Low Form, with KIMFLOW Fritted Disc, Kimble Chase 28260 152 aims to deliver exactly that. Manufactured by Kimble/Kontes, these crucibles are designed for gravimetric analysis, specifically for drying precipitates to a constant weight. The low form design and KIMFLOW fritted disc are intended to provide efficient filtration and even heating, crucial for accurate results.
My work in environmental science often requires me to analyze soil and water samples for particulate matter. I was struggling with inconsistent results using traditional filter paper, leading me to seek a more precise and reliable filtration method. I needed something that could withstand high temperatures for drying and provide consistent pore size for accurate residue determination.
Upon receiving the Kimble/Kontes KIMAX Gooch Crucible, I was immediately struck by its solid construction. The borosilicate glass felt robust, and the fritted disc appeared uniformly porous. It felt like a professional-grade piece of equipment, ready for serious lab work.
I considered using standard porcelain Gooch crucibles or even disposable filtration units. However, the Kimble/Kontes option promised a balance of durability, chemical resistance, and controlled porosity that the others lacked. Porcelain can be prone to cracking under thermal stress, and disposable units often lack the high-temperature tolerance I needed.
My first impression was definitely positive. It seemed like a well-engineered piece of lab equipment, and I was eager to see how it would perform in my analyses.
Real-World Testing: Putting Kimble/Kontes KIMAX Gooch Crucibles, Low Form, with KIMFLOW Fritted Disc, Kimble Chase 28260 152 to the Test
First Use Experience
My first test involved analyzing suspended solids in a river water sample. I set up a filtration apparatus and used the Kimble/Kontes KIMAX Gooch Crucible to filter the water, followed by oven-drying the crucible and residue at 105°C. The crucible handled the temperature change without any issues.
The crucible’s performance was consistent even when filtering slightly turbid samples. I found the filtration rate to be noticeably faster and more uniform than with filter paper. This significantly reduced my analysis time.
Using this crucible required minimal familiarization. The KIMFLOW fritted disc ensured even distribution of the filtrate. I encountered no issues with clogging or uneven drying.
After my first use, I noticed a significant improvement in the consistency of my results. The Kimble/Kontes Gooch Crucible provided a reliable and efficient filtration process.
Extended Use & Reliability
After several months of regular use (3-4 times per week), the Kimble/Kontes KIMAX Gooch Crucible is still holding up remarkably well. There are no signs of cracking or degradation of the fritted disc. The glass remains clear and resistant to staining.
Durability has been a standout feature. Despite repeated heating and cooling cycles and exposure to various solvents, the crucible shows no signs of wear. I have even accidentally dropped it a few times (thankfully from a low height), and it remained intact.
Cleaning the crucible is relatively easy. I simply rinse it with distilled water and, if necessary, soak it in a diluted acid solution to remove stubborn residues. The KIMFLOW fritted disc does require occasional back-flushing to maintain its porosity.
Compared to my previous experiences with filter paper and other filtration methods, the Kimble/Kontes KIMAX Gooch Crucible has been a game-changer. It provides more consistent results, is more durable, and saves me significant time in the lab.
