Compared to cheaper, thinner-walled funnels I’ve used in the past, the Kimble/Kontes felt like a significant upgrade. I had also considered a Corning separatory funnel, but the Kimble/Kontes seemed to offer a slightly more robust design in the stopcock area. I also looked at some plastic options, but the chemical resistance of glass was a must for my use.
My first impression was definitely positive; the Kimble/Kontes KIMAX Separatory Funnel appeared to be a professional-grade piece of equipment capable of handling demanding tasks. The investment seemed justified based on the initial impression of quality and durability.
Real-World Testing: Putting Kimble/Kontes KIMAX Separatory Funnels, Squibb, Pear-Shaped, Kimble Chase 29049F 1000 With High-Density Polyethylene Stopper And Ptfe Stopcock to the Test
First Use Experience
My first real test came during a large-batch herbal extraction project at a remote wilderness camp. The goal was to separate the extracted oils from the water-based solvent, a crucial step in creating potent topical remedies. The funnel was set up within a rudimentary outdoor laboratory, exposed to varying temperatures and some degree of humidity.
The Kimble/Kontes KIMAX Separatory Funnel performed admirably despite the less-than-ideal conditions. The PTFE Stopcock allowed for incredibly precise control over the drainage rate, minimizing waste. Even with slightly viscous extracts, the funnel emptied smoothly, and the pear shape proved to be very effective for separation.
Getting used to the size was a bit of an adjustment, as the 1000 mL capacity required careful handling to prevent accidental spills. Once I developed a good technique for securing the funnel, I had no problems. There were no leaks, even after several hours of continuous use, highlighting the quality of the stopper and stopcock.
Extended Use & Reliability
After several months of consistent use, the Kimble/Kontes KIMAX Separatory Funnel has proven to be a reliable workhorse. It has been used in a variety of extraction projects, handling different solvents and botanical materials. There has been no degradation of the glass or the PTFE Stopcock, attesting to its chemical resistance.
The funnel shows no signs of significant wear and tear, even with regular use and cleaning. Cleaning has been straightforward, requiring only mild soap and water followed by a thorough rinse. The large upper opening makes it easy to access the interior for cleaning.
Compared to my previous experiences with lower-quality funnels, the Kimble/Kontes is in a different league. Previous funnels often developed leaks or their plastic stopcocks would degrade with solvent exposure. This funnel is a true investment in durability and consistent performance.
