Real-World Testing: Putting Kimble/Kontes Test Tubes 20X150ML CS500 73500 20150 Test Tubes 20X150ML CS500, Case of 500 to the Test
First Use Experience
My first deployment of the Kimble/Kontes Test Tubes was during a water quality assessment in a remote alpine region. We used them to collect stream water samples for on-site pH and turbidity measurements before transporting them to the base lab for heavy metal analysis. The tubes were subjected to varying temperature fluctuations, from freezing nights to sun-exposed daytime conditions.
The tubes performed admirably under these conditions, with no visible signs of cracking or degradation. Their uniform size and shape made them easy to handle even with gloved hands, a necessity in cold environments. There were no initial issues or surprises, just reliable performance as expected.
Extended Use & Reliability
After several months of regular use across various projects, the Kimble/Kontes Test Tubes have proven to be a consistently reliable workhorse. The glass has shown good resistance to etching and staining, even after repeated exposure to acidic solutions and organic solvents. Breakage rates have been minimal, further solidifying their value.
Durability has been excellent, with minimal chipping or cracking observed despite frequent handling and transportation in rugged field packs. Cleaning is straightforward, with standard lab detergents easily removing residue and contaminants. Compared to previous experiences with lower-quality tubes that often succumbed to breakage or chemical attack, the Kimble/Kontes tubes significantly outperform.
Breaking Down the Features of Kimble/Kontes Test Tubes 20X150ML CS500 73500 20150 Test Tubes 20X150ML CS500, Case of 500
Specifications
- Description: TEST TUBES 20X150ML CS500. This refers to the dimensions (20mm diameter, 150mm length) and the case size (CS500, meaning a case of 500).
- Unit: Case of 500. The product is sold as a case containing 500 individual test tubes.
- Material: (Inferred from general knowledge of Kimble/Kontes products) Borosilicate Glass. Borosilicate glass is known for its excellent thermal shock resistance and chemical inertness.
- ASTM Specification: Designed from ASTM Specification E890. This specification relates to disposable glass culture tubes, ensuring consistent quality and dimensions.
These specifications are critical because they directly impact the functionality and suitability of the tubes for their intended purposes. The borosilicate glass ensures the tubes can withstand temperature changes without cracking, essential for experiments involving heating or cooling. The consistent dimensions, dictated by the ASTM specification, allow for precise volume measurements and compatibility with standard laboratory equipment.
Performance & Functionality
The Kimble/Kontes Test Tubes perform exceptionally well in their intended role as containers for chemical reactions and biological samples. They are chemically inert, preventing unwanted reactions with the contents. Their clear glass construction allows for easy visual inspection of the sample.
The primary strength lies in their reliability and consistency. The only minor area for improvement might be the addition of graduation marks for approximate volume measurement. However, this is a minor issue that can be easily addressed with external markers. Overall, the tubes meet and exceed expectations for basic laboratory use.
Design & Ergonomics
The simple cylindrical design of the Kimble/Kontes Test Tubes prioritizes functionality. The glass is of good quality, providing excellent clarity and resistance to chemical degradation. While lightweight individually, the case of 500 does require sturdy storage and handling.
The tubes are easy to use, requiring no specialized knowledge or techniques. Their standard size allows for easy integration with existing laboratory setups and equipment.
Durability & Maintenance
Given their borosilicate glass construction, the Kimble/Kontes Test Tubes are reasonably durable under normal laboratory conditions.
