Can I use Tungsten Carbide beads for RNA extraction protocols using QIAGEN Kits?
FAQ ID -3053

Tungsten Carbide beads react with lysis buffers e.g. buffer RLT, RLT Plus and QIAzol lysis reagent, used in QIAGEN’s RNA extraction kits. Therefore we do not recommend using the Tungsten Carbide beads with our RNA extraction kits.
