RapidCycler 2 Instrument The RapidCycler was the first instrument engineered to match the speed of biochemical reactions and is used by thousands of research centers worldwide. With the input of our loyal customers and key engineers, we have upgraded the original instrument to take advantage of standard 1.5 mm reaction cuvettes. These cuvettes which are also used in the Roche LightCycler® and Idaho Technology R.A.P.I.D. and HR-1™ instruments, allow researchers to conveniently transfer samples between instruments for additional analysis. The instrument's cycling system is based on heat transfer by hot air to its samples. Heating and cooling the samples with blasts of high velocity air results in nearly instantaneous temperature transactions which ensures temperature uniformity and rapid heat exchange within the sample.
