The LightCycler® 2.0 Sample Carousel (20 µl) has 32 positions to hold LightCycler® Capillaries (20 µl). The LightCycler® 2.0 Instrument positions capillaries (fitted into the sample carousel) precisely above the detection unit. The carousel is manufactured with a special plastic material (Peek), that is not only resistant to the temperature changes that occur during the thermal cycling process, but also maintains shape and dimensions during the process, a prerequisite for precise positioning and reproducible detection. Each LightCycler® 2.0 Sample Carousel (20 µl) is labeled with a unique bar code for reliable identification. Compatibility: The LightCycler® 2.0 Sample Carousel (20 µl) is only compatible with the LightCycler® Capillaries (20 µl) used with the LightCycler® 2.0 Instrument.
