Real-World Testing: Putting Thermo Scientific 4 mL Screw-Thread Vials, Thermo Scientific C4015-45 Septa to the Test
First Use Experience
The initial testing took place in our environmental testing lab, focusing on VOC analysis of soil and water samples. We used the vials in conjunction with our gas chromatograph-mass spectrometer (GC-MS). The vials were loaded into a Shimadzu autosampler, which they fit perfectly, just as described.
The septa provided a tight seal, even after multiple injections, which is crucial for preventing analyte loss. We consistently achieved accurate and reproducible results, demonstrating the integrity of the vials and septa. There were no issues or surprises during the first use.
Extended Use & Reliability
After several months of continuous use, the Thermo Scientific 4 mL Screw-Thread Vials, Thermo Scientific C4015-45 Septa have proven to be exceptionally reliable. The vials exhibit no signs of degradation or cracking, even after repeated exposure to various solvents and temperature fluctuations. Cleaning is straightforward; a simple wash with lab-grade detergent and thorough rinsing is sufficient.
Compared to my previous experience with less expensive vials, these have significantly outperformed expectations. The consistent seal and high-quality glass have minimized sample loss and contamination, leading to more accurate and reliable analytical results. I have experienced no problems with these vials so far.
