When your workflow includes semi-automated and fully-automated platforms for high throughput, Thermo Scientific? tubes allow robust storage and tracking of sample volumes ranging from 7μL to 12mL in 384-, 96-, 48- and 24-place arrays. We have storage formats available for temperatures down to VPLN, and multiple sealing options including ScrewTop caps and septa seals. Solid, one-piece construction means there are no labels to fall off and tubes made from medical-grade resins are supplied free of RNAse, DNAse, endotoxins and cytotoxins and SAL down to 10-6.
