Description
The PolyScience FT‑25 Flow-Through Cooler (Model F25N0A101B) provides powerful, cryogen-free cooling at a fixed –25 °C. Designed for integration with heated or refrigerated circulating baths, this unit features 3/8″ FPT inlet/outlet connectors, a 120 V/60 Hz power supply, and continuous operation capabilities up to 30 °C ambient.
Delivering 117 W cooling at –20 °C and U.S. standard 322 W at 0 °C, it supports efficient heat management in solvent recovery, freeze-point determination, lyophilization, and rapid cool-down processes. Despite its robust cooling power, it remains portable at 73 lb, compact at 17″ × 14″ × 14″, and easy to integrate into existing lab setups with anti-freeze circulating systems.
