Does "bulk" mean 10 bags of 50 tubes? Also are the racks made of styrofoam?

Asked by: Gidget89
Thank you for your question. There are 25 tubes per bag; 20 bags per case in the "bulk" format. If you purchase the racked tubes (rather than "bulk") then they are provided with a paperboard rack.

Your website (ordering information section) lacks critical information. For eg 15 ml bulk tubes SC-200250, there is no info on the # of tubes in this pack size. Another eg, Autoradiography film. 2 catalogue numbers, no info on size, customer has to guess

Rated 5 out of 5 by from Wonderful tubes! We have been using the 50 ML tubes for centrifuge and storage. They are durable and economical.

Rated 5 out of 5 by from Great product with an unbeatable price. This 50 mL tube works perfectly for centrifuge and sample storage in the freezer.

Rated 5 out of 5 by from Awesome tubes, not the most stringent QC It's been my experience where I have found tubes in a rack whose caps are more loose than expected. I've also found some that appear scuffed or dropped even though the packaging looks intact. Other than that, these are cheapest tubes in rack our company has been able to find.

Rated 5 out of 5 by from Our Go-To Choice Our company buys these quite often and they are by far one of the cheapest, although the biggest upside is the fact that there is free shipping and the Styrofoam they come in makes it quite easy to hold in the lab.

Rated 5 out of 5 by from Conical tubes I've been using this product since I began working in a brewing lab almost 4 years ago and they're great. Easy to open and close, and very simple to label with a permanent marker.
