Agilent Infinity II Sample Thermostat G7167-60201 (Refurbished)

Efficient temperature control of analytical samples is critical to achieving reliable, reproducible chromatography results, especially for temperature-sensitive compounds. The Agilent Infinity II Sample Thermostat (G7167-60201) is a dedicated module designed to work seamlessly with the Agilent 1260 and 1290 Infinity II Multisamplers. Its purpose is to maintain the thermal stability of vials and microplates before injection, enabling optimal sample integrity from storage through to analysis.

The G7167-60201 employs an advanced micro-compressor-based refrigeration system that provides both active cooling and heating across a broad temperature range. Air is drawn from the Multisampler's central chamber, cooled, and evenly distributed throughout the sample hotel to ensure consistent and precise thermal conditions across all stored containers. This design avoids the thermal gradients and inconsistencies that can affect retention times, peak shapes, and quantitation.

Condensation generated during cooling is safely channeled into a dedicated waste bottle, making the system clean, self-contained, and easy to maintain. Whether you're working with biological samples, temperature-sensitive pharmaceuticals, or any application requiring tightly regulated sample conditions, the Infinity II Sample Thermostat enhances reliability and throughput in LC workflows.
