Thermo Scientific TSV20FPSA11 Convertible Refrigerator/Freezer

The Thermo Scientific TSV20FPSA11 Convertible Refrigerator/Freezer is a versatile laboratory cold storage solution that allows users to operate the unit as either a laboratory refrigerator or a general-purpose laboratory freezer with the touch of a button. Offering 20 cubic feet (567 L) of storage capacity, the TSV20FPSA11 provides laboratories with the flexibility to adapt storage space as research needs change without purchasing two separate units. Operating as either a refrigerator from 2°C to 8°C or as a freezer from -12°C to -30°C, this convertible system is ideal for biotechnology companies, pharmaceutical manufacturers, hospitals, universities, clinical laboratories, and industrial research facilities.

The TSV20FPSA11 combines Thermo Scientific's dependable laboratory refrigeration technology with a simple electronic control system that allows operators to switch between refrigeration and freezer operation. Positive forced-air circulation, automatic defrost, environmentally friendly natural refrigerant, adjustable shelving, and a field-reversible door provide dependable performance while maximizing flexibility for laboratories with changing storage requirements.

Many laboratories pair the TSV20FPSA11 with ultra-low freezers, biosafety cabinets, centrifuges, and additional laboratory refrigerators to create a complete laboratory cold storage workflow.

Overview

The Thermo Scientific TSV20FPSA11 is designed for laboratories that require maximum flexibility from a single piece of equipment. Rather than dedicating valuable floor space to separate refrigerator and freezer units, the TSV20FPSA11 can easily be configured to meet current storage needs. This makes it an excellent solution for start-up laboratories, pilot facilities, research groups with evolving projects, or organizations seeking adaptable laboratory infrastructure.

The refrigerator/freezer utilizes positive forced-air circulation to maintain uniform temperatures throughout the cabinet, while electronic controls allow users to quickly change operating modes when laboratory requirements change. Automatic defrost simplifies routine maintenance, and the field-reversible door provides additional installation flexibility.

Common Applications

When configured as a refrigerator, the Thermo Scientific TSV20FPSA11 is commonly used for storing laboratory reagents, cell culture media, vaccines, biological specimens, pharmaceutical products, antibodies, enzymes, and quality-control materials between 2°C and 8°C. When operating in freezer mode, it provides dependable storage for enzymes, biological samples, tissue specimens, reagents, chemical standards, and other laboratory materials requiring temperatures between -12°C and -30°C, making it an excellent all-purpose cold storage solution for laboratories with changing workflows.

Why Choose the Thermo Scientific TSV20FPSA11?

The greatest advantage of the TSV20FPSA11 is flexibility. Laboratories are not locked into a single operating mode and can easily convert the unit from refrigerator to freezer—or back again—as storage needs evolve. This versatility reduces equipment costs, conserves valuable floor space, and provides laboratories with greater long-term adaptability than purchasing dedicated single-purpose equipment. Combined with Thermo Scientific's dependable refrigeration technology, the TSV20FPSA11 offers an excellent balance of performance, flexibility, and value.

Typical Stored Materials

The Thermo Scientific TSV20FPSA11 is commonly used to store laboratory reagents, biological specimens, vaccines, media, proteins, antibodies, enzymes, pharmaceuticals, diagnostic kits, calibration standards, frozen biological samples, tissue specimens, chemical standards, and other laboratory materials requiring either refrigerated or frozen storage.
