Bio-Rad Opticon 2

This is a used Bio-Rad Opticon 2 continuous fluorescence detection system, a workhorse real-time PCR instrument that has served countless labs performing gene expression and quantification assays. The unit has been in regular laboratory use and shows expected cosmetic wear, but it remains fully operational for standard qPCR workflows. The Opticon 2 offers continuous, real-time fluorescence monitoring across a 96-well thermal block, enabling researchers to track amplification in real time rather than relying solely on endpoint analysis. Its optical system supports common fluorophores used in SYBR Green and probe-based chemistries, making it suitable for a wide range of applications including gene expression profiling, pathogen screening, and genotyping work in academic and clinical research settings. Because of its straightforward interface and dependable Peltier thermal cycling, this Opticon 2 is well suited to teaching labs, core facilities, and smaller research groups that need a proven, budget-friendly real-time PCR platform. It represents a cost-effective alternative to newer systems while still delivering the core quantitative PCR functionality most labs require.
