Does the Kimble/Kontes Vial Scint Pe Pe Cap 7MLCS1000 58502 7 Deliver?

The Kimble/Kontes Vial Scint Pe Pe Cap 7MLCS1000 58502 7, manufactured by Kimble/Kontes, is a crucial component for scintillation counting in laboratory settings. These vials, designed for holding and analyzing radioactive samples, boast a 7mL capacity and come with polyethylene (PE) caps. The promise of reliable and consistent results hinges on the quality and integrity of these seemingly simple vials.

My own work in environmental radiation monitoring led me to seek out a reliable and consistent vial for liquid scintillation counting. I needed vials that could withstand various solvents, maintain sample integrity over extended periods, and provide consistent background counts. After struggling with inconsistent results from cheaper alternatives, I decided to invest in the Kimble/Kontes Vial Scint Pe Pe Cap 7MLCS1000 58502 7.

Upon unboxing, the immediate impression was one of quality control and precision. The vials felt sturdy, with consistent wall thickness and perfectly fitting caps. Compared to generic vials I had previously used, the Kimble/Kontes vials exhibited superior clarity and a more uniform construction.

I previously experimented with Wheaton scintillation vials and some cheaper, no-name brands. The Wheaton vials were good, but significantly more expensive. The generic vials, while affordable, resulted in fluctuating background counts and occasional leakage issues, making them unreliable for critical analysis. The Kimble/Kontes Vial Scint Pe Pe Cap 7MLCS1000 58502 7 seemed to strike a balance between quality and cost.

My initial impression was cautiously optimistic. While the price was considerably higher than the budget options, the visible quality gave me hope that I could finally achieve consistent and dependable results in my scintillation counting experiments. The uniform design and snug-fitting caps suggested a level of precision that I hadn’t experienced with other vials, which raised my expectations.

Real-World Testing: Putting Kimble/Kontes Vial Scint Pe Pe Cap 7MLCS1000 58502 7 to the Test

First Use Experience

I tested the Kimble/Kontes Vial Scint Pe Pe Cap 7MLCS1000 58502 7 in my lab, analyzing water samples for tritium and carbon-14. The samples were prepared using standard scintillation cocktails and then loaded into the Kimble/Kontes vials for counting in a liquid scintillation counter.

The vials performed flawlessly under various laboratory conditions, including room temperature, refrigerated storage, and exposure to different solvents. The PE caps provided a tight seal, preventing any leakage or evaporation of the scintillation cocktail, even after prolonged storage. The vials were easy to handle and load into the scintillation counter, with no noticeable issues related to size or shape variations.

The ease of use was immediately apparent. The caps screwed on smoothly and securely, unlike some cheaper vials where the threads were misaligned or the caps were too loose. There were no unexpected issues during the first use; background counts were stable and consistent, and the overall counting process proceeded smoothly.

Extended Use & Reliability

After several weeks of continuous use, the Kimble/Kontes Vial Scint Pe Pe Cap 7MLCS1000 58502 7 consistently delivered reliable and reproducible results. There were no instances of leakage, discoloration, or any other degradation that could compromise the accuracy of the measurements. The vials demonstrated excellent chemical resistance, with no signs of reaction or compatibility issues with commonly used scintillation cocktails.

The vials have proven to be exceptionally durable. Even after repeated use and cleaning, the vials maintained their structural integrity and clarity. The caps also held up well, with no cracking or deformation.

Maintaining the vials is straightforward. They can be easily cleaned with mild detergents and rinsed with deionized water. Autoclaving is possible for sterilization if needed, although I typically prefer to avoid autoclaving the PE caps due to potential deformation.

The Kimble/Kontes Vial Scint Pe Pe Cap 7MLCS1000 58502 7 far outperforms my previous experiences with cheaper vials. The consistent background counts, leak-proof design, and robust construction have significantly improved the reliability and accuracy of my scintillation counting experiments. The investment in quality vials has paid off in terms of reduced errors and increased confidence in the results.

Breaking Down the Features of Kimble/Kontes Vial Scint Pe Pe Cap 7MLCS1000 58502 7

Specifications

• Capacity: 7mL This is a standard volume for many liquid scintillation counting applications, providing sufficient sample volume for accurate measurements.
• Cap Material: Polyethylene (PE) PE offers good chemical resistance to many common solvents used in scintillation cocktails, preventing degradation and contamination of the sample.
• Vial Material: Not explicitly specified, but typically borosilicate glass for scintillation vials Borosilicate glass is known for its low background radiation and excellent chemical inertness.
• Application: Liquid Scintillation Counting Specifically designed for use in liquid scintillation counters for measuring radioactive decay.
• Case Quantity: 1000 Packaged in bulk for laboratories that perform a high volume of scintillation counting.

These specifications are important because they directly impact the accuracy, reliability, and efficiency of the scintillation counting process. The correct capacity ensures sufficient sample volume, while the chemical resistance of the materials prevents contamination and degradation. The low background radiation of the vial material is crucial for minimizing errors in low-level radioactivity measurements.

Performance & Functionality

The Kimble/Kontes Vial Scint Pe Pe Cap 7MLCS1000 58502 7 performs its job exceptionally well, providing a reliable container for radioactive samples in liquid scintillation counting. The tight seal of the PE cap prevents leakage and evaporation, ensuring sample integrity over time. The consistent background counts contribute to the accuracy of the measurements.

The vial’s strengths lie in its consistent quality, leak-proof design, and chemical resistance. A minor weakness could be that the PE caps might not be suitable for all types of organic solvents, but they are generally compatible with most common scintillation cocktails. Overall, it meets and exceeds my expectations.
