MJ Research PTC-200

This used MJ Research PTC-200 thermal cycler remains a workhorse in many laboratories thanks to its dependable Peltier based heating and cooling system and its rugged construction that has kept units in service for years past their original purchase date. The unit accepts a variety of interchangeable sample blocks, allowing labs to switch between 96 well, 384 well, and specialty formats depending on the assay being run, which makes it a flexible choice for research groups with varied workloads. Its simple keypad interface and proven thermal uniformity have made it a favorite among molecular biology labs performing routine amplification work. The PTC-200 supports gradient programming on select blocks, enabling researchers to optimize annealing temperatures across a single run rather than performing multiple experiments. This capability is especially valuable for laboratories developing new primer sets or troubleshooting difficult templates, since it saves both reagents and bench time. The heated lid design minimizes evaporation and condensation, contributing to consistent, reproducible results across long protocols. Laboratories purchasing this refurbished unit can expect a cost effective alternative to newer thermal cyclers while still achieving reliable amplification for PCR, RT-PCR, and related applications. It is well suited to teaching labs, core facilities, and smaller research groups that need dependable performance without the price tag of the latest instrumentation. This unit has been tested and cleaned prior to listing and is ready to be integrated into an active workflow.
