Let’s Dive into Kimble/Kontes KIMAX Centrifuge Tubes, Graduated, Conical-Bottom, with Screw Caps, Kimble Chase 45200 10 Heavy-Duty Tubes
The Kimble/Kontes KIMAX Centrifuge Tubes, Graduated, Conical-Bottom, with Screw Caps, Kimble Chase 45200 10 Heavy-Duty Tubes represent a cornerstone in laboratory science, offering reliable sample processing in a durable package. These aren’t your flimsy, disposable plastic tubes; they’re heavy-duty glass designed to withstand the rigors of centrifugation, making them essential for precise separations and analyses. The graduated markings and screw caps further enhance their utility, providing accuracy and secure sample containment.
My journey to these tubes started with a frustrating need for more robust sample handling during field research. I was tired of relying on less durable options that risked contamination or breakage during transport and processing of soil samples. The promise of the Kimble/Kontes KIMAX Centrifuge Tubes‘ heavy-duty construction and precise graduation marks was immediately appealing.
Upon unboxing, the first thing I noticed was the substantial feel of the glass. These weren’t the thin-walled tubes I was used to. The screw caps felt secure and created a tight seal, promising minimal risk of leakage.
I had been using standard borosilicate glass tubes from a different manufacturer, as well as some polypropylene tubes. The glass tubes were more prone to breakage, and the plastic tubes didn’t offer the same level of chemical resistance for certain soil extraction procedures. The Kimble/Kontes KIMAX Centrifuge Tubes seemed to offer a superior balance of durability and chemical compatibility.
My initial impression was one of cautious optimism. The price was higher than other options, but the perceived quality and durability suggested a long-term investment. I was eager to put them through their paces and see if they lived up to their “heavy-duty” claim.
Real-World Testing: Putting Kimble/Kontes KIMAX Centrifuge Tubes, Graduated, Conical-Bottom, with Screw Caps, Kimble Chase 45200 10 Heavy-Duty Tubes to the Test
First Use Experience
I first tested the Kimble/Kontes KIMAX Centrifuge Tubes in my mobile field lab, processing soil samples collected from a remote wetland area. The tubes were used to separate soil particles from water using a portable centrifuge powered by a generator. The conditions were demanding, with high humidity and fluctuating temperatures.
The tubes performed flawlessly under these conditions. The conical bottoms facilitated easy pellet formation during centrifugation, and the graduated markings allowed for precise measurements of supernatant volume. The screw caps prevented any leaks or spills, even during rough transport back to the main lab.
The ease of use was immediately apparent. The tubes were easy to fill, cap, and load into the centrifuge. There were no issues with balance or vibration, even at higher speeds.
After the first use, I noticed no chips, cracks, or other signs of damage. This was a significant improvement compared to the previous glass tubes I had used, which often showed signs of wear and tear after just a few uses.
Extended Use & Reliability
After several months of regular use, the Kimble/Kontes KIMAX Centrifuge Tubes have proven to be remarkably durable. They have been subjected to numerous centrifugation cycles, temperature fluctuations, and exposure to various chemical solutions without any noticeable degradation. There have been zero breakages.
The tubes have shown no signs of wear and tear, other than some minor staining from certain soil types. The graduations remain clear and legible, and the screw caps still provide a secure seal.
Cleaning and maintenance are straightforward. The tubes are easily cleaned with soap and water, and they can be autoclaved for sterilization without any damage. I have also used diluted acids to remove stubborn stains without any adverse effects.
Compared to my previous experiences with less durable tubes, the Kimble/Kontes KIMAX Centrifuge Tubes have been a game-changer. They have significantly reduced the risk of sample loss and contamination, and they have streamlined my workflow by eliminating the need for frequent replacements. They clearly outperform the previous equipment I was using.
Breaking Down the Features of Kimble/Kontes KIMAX Centrifuge Tubes, Graduated, Conical-Bottom, with Screw Caps, Kimble Chase 45200 10 Heavy-Duty Tubes
Specifications
The Kimble/Kontes KIMAX Centrifuge Tubes, Graduated, Conical-Bottom, with Screw Caps, Kimble Chase 45200 10 Heavy-Duty Tubes boast the following specifications:
- Volume: 10 mL. This is ideal for smaller sample volumes, which are common in environmental science.
- Dimensions: 17 mm O.D. x 116 mm L. The size is compact enough to fit in most standard centrifuges.
- Cap Size: 15-415. The screw cap provides a secure and leak-proof seal.
- Material: KIMAX borosilicate glass. This glass offers excellent chemical resistance and thermal stability.
- Graduations: Calibrated to contain. Precise markings ensure accurate volume measurements.
These specifications are crucial for ensuring accurate and reliable sample processing. The KIMAX glass is particularly important for withstanding the forces of centrifugation and the corrosive effects of various chemicals. The graduated markings ensure that volumes can be measured precisely, minimizing errors in downstream analyses.
Performance & Functionality
The Kimble/Kontes KIMAX Centrifuge Tubes excel in their primary function: separating substances by density using centrifugal force. The conical bottom facilitates the collection of solids at the bottom of the tube, and the graduated markings allow for precise removal of the supernatant.
The tubes are exceptionally reliable. They have consistently withstood high centrifugal forces without any signs of cracking or breaking. The screw caps provide a secure seal, preventing leaks and contamination.
One slight weakness is the lack of a marking spot large enough to clearly label each tube with a permanent marker in fine detail. A larger marking area would improve organization and tracking.
Overall, the Kimble/Kontes KIMAX Centrifuge Tubes meet and exceed my expectations. Their durability, accuracy, and ease of use make them an invaluable tool for my field research.
