Each sample transfer rack for the HotBlock™ is designed to hold and handle eighteen 50mL samples (use our 50mL digestion cups). Racks are made of polycarbonate for heat and acid resistance. Racks improve temperature and evaporation uniformity during digestion and facilitate handling of samples. Our SC100 HotBlock comes complete with two racks while our SC154 HotBlock comes with three.

All holes for cups in racks have notches to accommodate the Rak Lok style cups.
