Real-World Testing: Putting Kimble/kontes Disposable Plain Centrifuge Tubes, Kimble Chase 73785 50 to the Test

First Use Experience

I first put the Kimble/kontes Disposable Plain Centrifuge Tubes, Kimble Chase 73785 50 to the test during a water quality assessment in a remote mountain stream. The tubes were used to collect water samples for sediment analysis. I needed to separate suspended solids from the water to measure turbidity and analyze the sediment composition.

Despite some light rain and muddy conditions, the tubes were easy to handle and fill, even with gloved hands. The screw caps sealed tightly, preventing any leaks during transport. The conical bottom proved very useful in concentrating the sediment at the bottom of the tube, facilitating accurate measurements.

There were no immediate issues, and the tubes performed exactly as expected. The borosilicate glass held up well despite being jostled around in my backpack.

Extended Use & Reliability

After several weeks of repeated use in diverse environments, the Kimble/kontes Disposable Plain Centrifuge Tubes, Kimble Chase 73785 50 have proven to be remarkably reliable. They’ve been used in temperatures ranging from near-freezing to well over 90°F, and in environments ranging from arid deserts to humid wetlands.

The tubes show no signs of significant wear and tear beyond the occasional smudge or scratch. The caps continue to seal tightly, preventing leaks even after multiple uses (before being disposed of, of course!). Cleaning is straightforward – a simple rinse with distilled water is usually sufficient to remove any residue.

Compared to my previous experience with lower-quality plastic tubes, these Kimble/kontes tubes are a significant upgrade. The superior chemical resistance and structural integrity of the borosilicate glass make a noticeable difference in the accuracy and reliability of my results.

Breaking Down the Features of Kimble/kontes Disposable Plain Centrifuge Tubes, Kimble Chase 73785 50

Specifications

The Kimble/kontes Disposable Plain Centrifuge Tubes, Kimble Chase 73785 50 have the following specifications:

  • Capacity: 50mL. This is an ideal volume for a wide range of sample collection and analysis applications.
  • Material: Borosilicate glass. Borosilicate glass provides excellent chemical resistance and thermal stability, crucial for reliable results.
  • Bottom Shape: Conical. The conical bottom concentrates sediment for efficient separation and analysis.
  • Cap Type: Phenolic screw type with PTFE-faced rubber liner. These caps ensure a tight, leak-proof seal, preventing contamination and sample loss.
  • Maximum RCF: 2980 g. This rating indicates the maximum centrifugal force the tubes can withstand, ensuring they won’t break during centrifugation.
  • Glass Type: Meets Type I, A, or B glass requirements per ASTM E438. Adherence to these standards guarantees the quality and purity of the glass.

These specifications are critical because they directly impact the accuracy, reliability, and safety of sample collection and analysis. Using inferior tubes can lead to inaccurate results, sample contamination, or even breakage during centrifugation, which could jeopardize an entire project.
