Description: The TSV and TSG series are both designated for general-purpose laboratory storage of non-critical reagents, media, and samples, with a focus on sustainability and efficiency. Key features across the two series include the use of SNAP-compliant, environmentally friendly hydrocarbon refrigerants, digital or adjustable temperature controls, and robust designs. The TSV series offers manual defrost freezers (TSV05FPSA, TSV18FPSA) and convertible refrigerator/freezer options, while the TSG series features whisper-quiet operation ($\le 60\text{ dBA}$), adaptive (auto) defrost, ENERGY STAR certification, and advanced digital microprocessor alarms with battery backup across its larger models (e.g., TSG25FSSA, TSG49FSSA).
