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

Asked by: Umesh
Thank you for your inquiry. We are aware of the formatting issue with our labware section of the new website and are working to resolve it as quickly as possible, we appreciate your patience and reaching out to us. For our UltraCruz® Centrifuge Tube, Conical, 15 ml, bulk sc-200250, the quantity is 500/case. The same quantity for the UltraCruz® Centrifuge Tube, Conical, 15 ml, racked sc-200249. For the autoradiography film, the products are UltraCruz® Autoradiography Film, Blue, 5" x 7" sc-201696 and UltraCruz® Autoradiography Film, Blue, 8" x10" sc-201697.
