Centrifuge Tubes 200 Pack 2ml Polypropylene Clear Graduated Mirco Test Tubes with Snap Cap for Sample Storage Container No-Leak

These centrifuge tubes have been perfect for my laboratory and scientific projects. The 200-pack provides excellent value and ensures I always have tubes on hand. The 2mL capacity is ideal for small sample volumes and fits perfectly in standard centrifuge rotors. The polypropylene construction is high quality - durable and chemical resistant. The graduated markings are clear and accurate, making it easy to measure precise volumes. The snap caps seal tightly and securely, preventing leaks even at high centrifuge speeds. I appreciate that they're sterile and individually packaged which is important for maintaining sample integrity. The tubes are autoclavable which allows for sterilization and reuse when needed. The clarity of the plastic makes it easy to see sample contents and check for proper separation. The writing surface on the tube allows for easy labeling with permanent markers. These work perfectly for DNA extraction, protein precipitation, and general sample storage. Essential for anyone doing laboratory work, whether professional or hobbyist. Great quality at a reasonable price.

Perfect for my chemical experiments!

I'm using these for pyro deployment charges in model rockets. They work great. Honestly, if I were looking to use these for clinical purposes where their being sterile and clean was absolutely necessary, I should rethink my profession of choice because choosing to buy from China instead of a reputable source means I don't care about what I'm doing.

They said that they would ship within one day but they did not. Actually they took like 5 days. Other than that these have really come in handy. Other than one or two being faulty or something and leaking a little bit, they work perfectly and make my life much easier

I primarily use this for gluing 3D printed projects together, the little tubes keep the mess confined, can be sealed so the odors don't linger forever once completed, and measuring lines help with keeping the 1:1 ratio pretty accurate.

Geocachers, if you need one of these to put in signposts these are great. Perfect size.
