VWR VWR-VS-23S Premier Solid Door Laboratory Refrigerator, Microprocessor Precision Control, Patented Forced-Draft Airflow, Self-Closing, 23 cu. ft.

The VWR Premier Solid Door Laboratory Refrigerator (VWR-VS-23S) is engineered with advanced variable speed compressor technology and precise microprocessor controls to deliver exceptional energy efficiency, performance, and temperature stability in clinical and research environments. With a generous 23 cubic foot (651 L) capacity, this single-door upright laboratory refrigerator provides highly secure and reliable cold storage while optimizing workflow efficiency in busy lab settings.

Constructed for demanding laboratory use, the cabinet features a durable white powder-coated steel exterior. It is equipped with a single swing solid door that is self-closing, right-hinged, and non-reversible. The solid door design provides superior thermal insulation and complete opacity for light-sensitive material storage, reinforced by a positive magnetic gasket to prevent ambient heat infiltration. The entire cabinet structure is foamed-in-place with EPA-compliant, high-density urethane foam to ensure optimal thermal performance. For security, a physical keyed access lock is standard, and the door is compatible with optional automated electronic digital locks such as Pyxis, Omnicell, and AcuDose RX.

The interior layout is designed for organized and flexible workflows. It features four adjustable shelves that can be repositioned in precise 1/2” increments to seamlessly accommodate varied sample sizes, media, or diagnostic kits. Switch-controlled interior LED lights are safety shielded to protect delicate materials from direct exposure. For mobility and easy placement, the unit is mounted on sturdy swivel casters with locking front casters. A 3/4" probe access port is pre-drilled on the rear wall, allowing users to integrate independent validation probes or data loggers without altering the cabinet structure.

Thermal performance is managed by a precise microprocessor temperature controller switchable between Celsius and Fahrenheit with a fine 0.1°C / 0.2°F resolution. Operating within an adjustable range of 2°C to 15°C, the unit features patented airflow technology alongside a forced-draft circulation system that actively eliminates hot spots, providing a maximum cabinet air temperature variation of +/- 1.5°C. The automatic cycle defrost framework operates cleanly without compromising internal stability. A product simulator bottle filled with glass bead media houses the display probe to accurately represent actual sample-level temperatures.

Monitoring and system safety are supported by a clear digital temperature display and a comprehensive system of protective audible and visual alarms. The system alerts users to high/low temperature shifts, sensor errors, power failure events, and door ajar conditions. Integrated battery backup ensures uninterrupted temperature display and alarm functionality during power losses. The unit also features standard remote alarm contacts for facility-wide monitoring systems.

Running on EPA SNAP-compliant R600a natural hydrocarbon refrigerant, this energy-efficient refrigerator minimizes your laboratory's carbon footprint while meeting or exceeding strict ENERGY STAR® v2.0 standards, consuming less than 1.2 KWh/day. It operates at an ultra-quiet noise pressure level of 40 dBA or less installed.
