Lab folks, this one's for you!

These Scientific microcentrifuge tube racks are seriously handy for keeping your 5.0ml tubes organized and accessible.

Each rack holds 25 tubes with numbered wells so you can actually remember which tube is which - no more guessing games during important experiments.

They're made from durable polypropylene that can handle pretty much anything you throw at it - autoclaving for sterilization?
No problem.
Need to freeze them at -90°C?

They've got you covered.

And you're getting a pack of 5 racks, which is perfect for setting up multiple experiments or having backups ready to go.
The bright red color makes them easy to spot in a busy lab, and the compact design doesn't take up much bench space.
Whether you're in research, clinical work, or teaching labs, these reusable racks will save you time and frustration.
They're stackable too, so storage is a breeze.
The wells are perfectly sized for standard 5.0ml tubes, holding them securely without being too tight.
For the price, you're getting quality lab organization that stands up to heavy use and repeated sterilization cycles.
