Ever been in the middle of an experiment and realized your tubes are leaking or the markings are smudged? These 0.5mL microcentrifuge tubes solve that hassle right away. With a secure snap cap that clicks firmly into place, they hold everything from DNA samples to homemade essential oils without a drop escaping, even at high speeds.
Made from high-quality polypropylene, these tubes stand up to repeated centrifuging, freezing down to -80°C, and autoclaving up to 121°C. The crystal-clear walls let you see contents easily, while bold graduations at 0.1mL, 0.2mL, 0.3mL, 0.4mL, and 0.5mL make pipetting a breeze—no guessing games. They're non-pyrogenic and DNase/RNase-free, so your results stay pure whether you're in a professional lab, classroom, or home setup tinkering with biotech projects.
Picture this: you're running gel electrophoresis late at night, and these tubes keep your aliquots perfect. Or teaching kids basic science—fill them with colored water or sand to show density differences safely. At 1000 per pack, you'll have plenty for months of projects, and the flat-top caps make labeling straightforward with markers or tape.
Unlike flimsy alternatives, these hold conical bottoms for complete sample recovery, minimizing waste. They're lightweight yet tough, stacking neatly in racks or boxes to save bench space. Science enthusiasts, hobbyist biologists, teachers, and researchers all swear by them for consistent performance. Grab a pack and forget about tube failures—focus on your discoveries instead.
Compatible with most standard centrifuges and rotors, these mini lab tubes bring pro-level reliability to your workspace. Whether organizing microscopic samples or crafting custom kits, they're the quiet workhorse you didn't know you needed.
