Real-World Testing: Putting Kimble/Kontes KIMAX Gooch Crucibles, High Form, with KIMFLOW Fritted Disc, Kimble Chase 28250 302 to the Test
First Use Experience
My initial testing ground was my makeshift laboratory setup in my garage. This involves processing soil samples from various locations on my property. The first test involved filtering a slurry of soil and distilled water to separate the particulate matter from the liquid. The Kimble/Kontes crucible performed admirably, providing a consistent flow rate and preventing fine particles from passing through, unlike my previous attempts with less sophisticated filtration methods.
During the initial drying phase at 110°C, I observed no signs of stress or deformation in the glass, even after prolonged exposure to heat. The crucible’s high form aided in preventing spillage and ensured even heat distribution across the sample. After the first use, cleanup was simple; any remaining soil residue was easily removed with a brush and distilled water. However, I had to be careful to avoid sudden temperature changes, as the product description advised.
Extended Use & Reliability
After months of consistent use, processing dozens of soil samples, the Kimble/Kontes KIMAX Gooch Crucibles, High Form, with KIMFLOW Fritted Disc, Kimble Chase 28250 302 has proven remarkably durable. There are no visible cracks or chips, and the fritted disc maintains its consistent porosity, even after repeated filtration and drying cycles. Regular cleaning with distilled water and a soft brush has been sufficient to maintain its performance.
Compared to my previous, frustrating attempts at soil analysis with makeshift funnels and filters, the Kimble/Kontes crucible has been a game-changer. The results are significantly more consistent and repeatable, providing a solid foundation for my analysis. This crucible’s reliability far exceeds my initial expectations, making it a valuable asset in my soil analysis project.
Breaking Down the Features of Kimble/Kontes KIMAX Gooch Crucibles, High Form, with KIMFLOW Fritted Disc, Kimble Chase 28250 302
Specifications
The Kimble/Kontes KIMAX Gooch Crucibles, High Form, with KIMFLOW Fritted Disc, Kimble Chase 28250 302 boasts several key specifications that contribute to its performance. It has a 30mL capacity, suitable for most standard laboratory filtration procedures. The dimensions are 35mm in diameter and 60mm in height, providing ample space for sample processing while maintaining a manageable size.
The 30mm diameter KIMFLOW fritted disc is constructed from borosilicate glass, known for its chemical resistance and thermal stability. This crucial feature provides medium porosity, allowing for efficient filtration of precipitates while retaining fine particles. The Kimble/Kontes crucible is designed for precipitates to be dried to a constant weight at 110°C, and can be used in an electric furnace at higher temperatures if cooled to 250°C before removal. These specifications are vital because they ensure the crucible can withstand the rigors of repeated use and provide consistent, accurate results.
Performance & Functionality
The Kimble/Kontes KIMAX Gooch Crucibles, High Form, with KIMFLOW Fritted Disc, Kimble Chase 28250 302 excels in its core function: separating solids from liquids via filtration. The medium porosity fritted disc allows for rapid and effective filtration of a wide range of sample types, from soil slurries to chemical solutions. The high form design minimizes the risk of spillage during filtration and drying.
One minor weakness is the fragility of the glass construction; while durable for laboratory use, it requires careful handling to avoid breakage. Overall, the Kimble/Kontes crucible meets and exceeds my expectations for consistent, reliable filtration and drying, essential for accurate soil analysis.
