Product Overview
The Roundfin RD-2290 Cryostat is a state-of-the-art instrument designed for high-performance frozen sectioning in pathology, biomedical research, and clinical diagnostics. It integrates rapid cooling, precise temperature control, and intelligent operation to ensure optimal sample preservation and superior slice quality. Engineered for efficiency and user safety, the RD-2290 streamlines the entire workflow from sample freezing to sectioning.
At its core, the RD-2290 is powered by an international brand Secop dual-compressor system delivering powerful, reliable, and quiet refrigeration. The instrument provides five-point separate cooling to the freezing chamber, freezing table, blade holder, specimen head, and tissue flattener for uniform and stable temperatures. The Peltier (semiconductor) assist cooling reaches an ultra-low -65 °C on the freezing table, enabling fast freezing in just 15 minutes.
