### ⭐⭐⭐⭐⭐ Seem to be great!
*by S***. on February 19, 2022*

I'm not using these in an actual centrifuge. I bought them for pre-measuring out oxy shock powder for my hot tub. They work wonderfully for this. The lids fit tightly and stay put, graduation markings are solid and easy to read, and they're very inexpensive. This ticks all of the boxes for my needs.
