Thermo Scientific™ TSX Series high-performance -30°C auto defrost freezers are designed with features that support sample protection and sustainability objectives for the storage reagents, pharmaceuticals, vaccines, biological and other commonly used laboratory and clinical materials such as primers, siRNA molecules and fetal bovine serum (FBS) requiring -30°C. The Series’ V-drive technology is designed to provide temperature uniformity that continually adapts to user patterns, offering significant energy savings without compromising protection.

Certified to NSF/ANSI 456 Vaccine Storage* standard, the TSX series can help you meet regulations and guidelines from the CDC, World Health Organization, and other Health Ministries on vaccine storage and handling.

The TSX Series delivers the performance and quality you need, in addition to the low sound, low energy, and exceptional user experience you deserve.

*For NSF/ANSI 456 compliance, units must be ordered with a certificate of calibration (6916-2)
