With motorized lid cover and Silver heating block. The Mastercycler ep family of thermal cyclers are thermoblocks with extremely fast heating and cooling speeds and unique heated lid technology (ESP-Electronic Sample Protection), which avoids the preheating of samples and minimizes unspecific annealing. The gradient option of each Mastercycler ep system features our SteadySlopeï¿½ technology to ensure that the heating and cooling ramp rates are identical in both gradient and normal operation-that means you can expect identical temperature control characteristics in both optimization and routine experiments, as well as a reliable transfer of the optimization results to the routine application. Programming with the Control Panel is easy and intuitive; so much so that novice users can get started quickly and safely. 115V/ 50-60Hz. Sample capacity: 96 x 0.2 ml PCR tubes or 1 PCR plate 8 x 12. Temp control range of 4-99 degrees C. Heating rate approx. 6 degrees C/s., cooling rate approx. 4.5 degrees C/s.
