Just what I needed. Great sturdy centrifuge tubes.

Good, low cost conical tubes with strong, reusable racks. I like them as well as Fisher's nunc tubes and they are a fraction of the price. They are sterile and do not leak when used in a vortex mixer

These tubes are great. They have worked perfectly for growing my Chlorella vulgaris algae without contamination. The rack they come with is not extremely sturdy but is very convenient and works fine. I would give five stars but when the package arrived one of the lids from one of the tubes was off inside the package so I was unable to use that tube for sterile application. Overall a great product especially for the price!

This is the fifth time I have ordered this product and it always comes as delivered and works well doing research. Reasonably priced and good quality.

Came quickly and made well. No molding edges or trash still attached. Look good enough to be glass and the rack is handy. In total transparency, I use these in the oil patch " to grind out" or test for water in an oil sample. The centrifuges were always hand crank or grinders so ended up called a grind out machine.😀

Affordable solution for yeast ranching! Make a yeast starter, and pour the slurry into the tubes. Works great!

The tubes definitely met my needs. They were clean inside, with easy to use caps and a convenient stand, as well as good optical clarity. I'd buy them again.

The caps screw on tightly preventing leakage. For the money, these tubes work very well. I will definitely purchase again.

Came with the holder broken in 2 places; 1 well on each side. I can still use it just fine, just 2 less usable wells. Overall quite sturdy, even while missing 2 corners. Tubes look great. Could not reach any form of customer support because I'm forced to go through Amazon bot chat and no options exist to just give feedback directly via message to the seller like I've done in the past; only to seek a return/return&replacement, which is not worth my energy since its still usable, but it should be known when an item arrives damaged. So I'm leaving this review. Not my ideal way of letting a seller know.
