The EdvoCycler™ is a standalone classroom PCR machine that is easy to use! The 0.2 ml tube block has room for up to 25 student samples and comes pre-programmed with all Edvotek PCR kit protocols. These programs may be modified or deleted, plus there’s extra memory for more. The vivid 7-line LCD displays all program parameters simultaneously on a single screen. A heated oil-free lid makes operation a snap. Proudly made in the USA
