SPL 15 ml Conical Centrifuge Tubes Sterilized with PP Racks,DNase/RNase - Free, 25 Tubes x Rack (1 Rack)

Great Product.

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.

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.
