First Use Experience

I first tested the Kimble/Kontes KIMAX Centrifuge Tubes during a water quality assessment project in a remote alpine region. The primary goal was to collect water samples from various sources (streams, lakes, snowmelt) and separate sediment for later analysis. I needed to do preliminary separation on site.

The tubes performed admirably in a variety of conditions. Despite fluctuating temperatures ranging from below freezing to sunny afternoons, the KIMAX glass showed no signs of stress or cracking. The stoppers held firm, even when the tubes were jostled during transport in my pack.

The conical bottom made sediment collection a breeze. After allowing the samples to settle, the graduated markings allowed for easy and accurate measurement of sediment volume. There was no need to guess the amount of sediment present; I could read the measurement clearly, making my preliminary assessments more accurate.

My only initial concern was the fragility of the glass in a field environment. However, with careful handling and proper padding in my pack, I experienced no breakages during the first few days of testing. That said, I would love to see Kimble/Kontes produce some ruggedized cases.

Extended Use & Reliability

After several weeks of continuous use, the Kimble/Kontes KIMAX Centrifuge Tubes continued to impress. They became an integral part of my field sampling workflow, allowing me to efficiently process samples on-site and reduce the number of trips back to base camp. They saved valuable time and manpower.

The glass showed no signs of clouding or etching, even after repeated exposure to various water and soil types. The graduated markings remained clear and legible, a testament to the quality of the ceramic enamel printing.

Maintenance was straightforward. After each use, the tubes were easily cleaned with water and a brush. Occasional sterilization with isopropyl alcohol ensured no cross-contamination between samples.

Compared to using improvised methods for sample separation (e.g., plastic bottles, makeshift filters), the Kimble/Kontes KIMAX Centrifuge Tubes offered a significant improvement in accuracy, efficiency, and reliability. They outperformed my expectations and proved to be a valuable asset for field research. The glass stopper also proved to be more reliable than standard test tube caps.

Specifications

The Kimble/Kontes KIMAX Centrifuge Tubes boast several key specifications that contribute to their performance and suitability for field use. Each tube has a volume of 15mL, suitable for small sample sizes. The stopper size is 13, providing a secure seal without being overly difficult to remove.

The dimensions are 17mm (O.D.) x 136mm (L), compact enough for easy packing yet large enough for meaningful sample collection. The Kimble Chase No. is 45153 15, important for ordering replacements or additional tubes. The graduated markings are in 0.1mL increments, allowing for precise measurements.

The use of KIMAX borosilicate glass is crucial for durability and chemical resistance. This ensures the tubes can withstand temperature fluctuations and contact with various substances without degrading or affecting sample integrity. The pennyhead ST glass stoppers offer an airtight seal, preventing leakage and contamination.

Performance & Functionality

The primary function of these centrifuge tubes is to allow for sample separation and measurement. The conical bottom facilitates the settling of solids, while the graduated markings enable accurate volume readings. The ST glass stopper, while not intended for use during centrifugation, effectively seals the tube for transport and storage after processing.

These tubes excel at what they are designed to do. The clear glass and precise markings ensure accurate measurements, while the durable construction allows for repeated use in demanding environments. The 15mL capacity is ideal for many field sampling applications.

However, they are glass, so they are inherently vulnerable to breakage if dropped or mishandled. The stoppers are also susceptible to damage if not handled with care. While the design is functional, it lacks any features specifically tailored for outdoor use, such as a protective coating or shock-absorbing sleeve.

Design & Ergonomics

The Kimble/Kontes KIMAX Centrifuge Tubes are designed for functionality and precision. The KIMAX borosilicate glass provides excellent clarity and chemical resistance, while the conical bottom aids in sediment collection. The glass stopper ensures a tight seal.
