Let’s Dive into Kimble/Kontes Scintillation Vials, Borosilicate Glass, with Screw Cap VW74504 20, Case of 500
The Kimble/Kontes Scintillation Vials, Borosilicate Glass, with Screw Cap VW74504 20, Case of 500 represent a cornerstone in laboratory research, essential for accurate and reliable liquid scintillation counting. Manufactured by Kimble/Kontes, a name synonymous with quality labware, these vials are designed to meet the stringent demands of scientific applications. With their consistent dimensions, durable borosilicate glass construction, and secure screw-cap closures, they offer researchers a dependable solution for handling radioactive samples. A case of 500 promises consistent results, making research faster and easier.
My work in environmental remediation often involves analyzing trace amounts of contaminants in water and soil samples. Liquid scintillation counting is crucial for detecting and quantifying these radioactive isotopes. Finding vials that consistently deliver low background counts and prevent sample leakage has been a constant struggle.
The promise of Kimble/Kontes quality was enticing. The vials arrived meticulously packed in cellular trays, 100 per tray, within the case of 500. The first thing I noticed was the uniformity of the vials; each one appeared flawless, a testament to Kimble/Kontes‘ commitment to precision.
I’ve used cheaper plastic vials and other glass options with varying results. Some suffered from high background counts due to plastic leaching, others leaked even with careful cap tightening, and some were simply inconsistent in their dimensions. The Kimble/Kontes vials seemed a cut above, promising a blend of reliability and precision that the others lacked.
My initial reaction was relief and cautious optimism. Finally, a product that seemed to address the core issues I’ve faced in my work, offering a solution rather than another compromise. I was eager to put them to the test and see if they lived up to the Kimble/Kontes reputation.
Real-World Testing: Putting Kimble/Kontes Scintillation Vials, Borosilicate Glass, with Screw Cap VW74504 20, Case of 500 to the Test
First Use Experience
I first tested the Kimble/Kontes Scintillation Vials in our laboratory while processing samples from a contaminated industrial site. The testing involved adding scintillation cocktail to the samples within the vials and measuring the resulting light output using a liquid scintillation counter. The vials were used in ambient lab conditions, approximately 70°F with moderate humidity.
The performance was immediately noticeable. The vials were easy to handle, the screw caps provided a tight, secure seal preventing any leakage, and the borosilicate glass minimized background counts. I found the vials easy to label and organize within the counter’s sample carousel.
The only surprise was the initial tightness of the caps. They required a bit more effort to open initially, which, while ensuring a secure seal, necessitated a more deliberate opening procedure. This was a minor inconvenience but one worth noting for users who might be handling large numbers of samples quickly.
Extended Use & Reliability
After several months of consistent use, the Kimble/Kontes Scintillation Vials have proven to be remarkably reliable. The borosilicate glass shows no signs of degradation or leaching, maintaining consistent low background counts. The screw caps continue to provide a secure seal, preventing any sample loss or contamination.
The vials are easy to clean with standard laboratory detergents and are autoclavable for sterilization. Compared to my previous experiences with cheaper vials that cracked or developed leaks over time, these vials have demonstrated exceptional durability. They have clearly outperformed my expectations, offering a long-term, reliable solution for scintillation counting.
