Are you homogenizing samples for collecting RNA? We now offer RNase free beads in all 6 sizes of stainless steel that we carry (in addition to all 4 sizes of zirconium oxide and 2 common sizes of glass beads). Also, to help you aliquot beads into sample tubes, we also introduced spoons in RNase free versions (MSP01 – 100 ul and MSP05 – 500 ul).
