On the basis of 50mL, people designed the original 25mL centrifuge tube. As we know, usually we need an adapter to use the tube, which makes the use process more cumbersome and increases the use budget. Our team noticed this issue. After repeated tests, here’s a solution: a new 25ml centrifuge tube (doesn’t need for an adapter).
Frosted design on the lid simulates the writing feel on paper, which makes writing smoothly.
The circular drop on the lids for easy labeling.
Thread extension is ergonomically designed to reduce the fatigue of screwing the lid.
