Eppendorf PCR Tubes designed for use in most thermal cyclers with heated lids. Thin wall, tight seal, and high transparency provide reproducibility. Available in 0.2 mL and 0.5 mL sizes. A contamination shield prevents contact with the inner lid surface. 0.5 mL tubes feature a unique lid design to allow for maximum capacity in universal blocks of Eppendorf Mastercyclers.
