Picture this: you're in the middle of a crucial HPLC run, and you realize your samples might be degrading under lab lights. That's where these amber 2ml autosampler vials come in—they're your reliable shield against light exposure that can ruin delicate compounds.
These 9-425 vials are the standard size for most HPLC and GC systems, ensuring seamless compatibility with your autosampler. The rich amber glass filters out UV light while letting you see your sample clearly. Graduations etched right on the vial let you measure volumes down to 0.2ml increments without needing extra tools, and the flat write-on spot accepts any marker for smudge-free labeling that stays put even in busy labs.
No more worrying about evaporation or leaks. The 9mm blue ABS screw caps come pre-assembled with PTFE/Rubber septa that pierce cleanly for needle injections and reseal tightly afterward. Made from robust materials, they withstand repeated use, making this 100-pack a smart buy for high-volume testing or stocking your lab bench.
Whether you're running pharmaceutical assays, environmental analysis, or educational experiments, these vials handle it all. Students love how easy they are to use during organic chemistry labs; pros appreciate the consistency in chromatography results. They're also great for smaller setups like home distillation monitoring or essential oil storage where light protection matters.
Handling feels solid—the vials nest neatly without scratching, and the screw threads engage smoothly every time. At this quantity, you're set for months of work without interruptions. Users rave about how they cut down on sample prep time, letting you focus on the science, not the supplies.
Invest in quality that pays off in accurate data and fewer reruns. These Membrane Solutions vials have earned their spot as a lab staple for good reason.
