Eppendorf invented the microcentrifuge tube in 1963. Eppendorf tubes® have shown to be reliable companions for your daily work. The Eppendorf Fast PCR Tube Strips made of Polyethylene transfer heat faster than the tubes made of traditional plastics. The Fast PCR Tube Strips are particularly suited to scientists using Fast PCR Reagent Kits, scientists trying to speed up protocols or cyclers with high heating and cooling rates – such as the Eppendorf Mastercycler X50 family.
