VWR SCUCFS-0420 Overview

The SCUCFS-0420 was designed for laboratories requiring dependable frozen storage without unnecessary complexity. Rather than incorporating advanced electronic controls and monitoring systems, this freezer emphasizes reliability, ease of operation, and cost-effective performance for everyday laboratory applications.

Its freestanding cabinet is ideal for laboratories where frozen materials need to remain close to the workspace. The drawer-based interior helps organize samples while minimizing the amount of cold air lost during retrieval, making routine access more efficient throughout the workday. Because this model is designed for freestanding installation, adequate ventilation around the cabinet helps ensure consistent cooling performance and long equipment life.

Common Applications

The VWR SCUCFS-0420 is commonly used for storing:

• Laboratory reagents

• PCR reagents

• Restriction enzymes

• Antibodies

• Buffers

• Laboratory standards

• Pharmaceutical products

• Environmental testing samples

• Quality control materials

• Research specimens requiring -20°C storage

Its compact footprint makes it especially useful in laboratories where dedicated frozen storage is needed directly within the work area.

Ideal Laboratory Types

The SCUCFS-0420 is well suited for:

• Biotechnology laboratories

• Pharmaceutical laboratories

• Academic research laboratories

• Clinical laboratories

• Environmental testing laboratories

• Industrial quality control laboratories

• Government laboratories

• Teaching laboratories

Laboratories requiring dependable frozen storage for routine research materials will appreciate the freezer's compact size, straightforward controls, and reliable performance.

Workflow & Space Efficiency

Keeping frequently used frozen materials close to the laboratory bench improves efficiency by reducing trips to centralized cold storage. The SCUCFS-0420's compact footprint fits comfortably beneath laboratory countertops while the four pull-out drawers simplify sample organization and retrieval.

The manual defrost refrigeration system also eliminates the warming cycles associated with automatic defrost freezers, making it a practical choice for many temperature-sensitive laboratory reagents while providing dependable long-term operation.

Typical Stored Materials

The VWR SCUCFS-0420 is commonly used to store PCR reagents, restriction enzymes, antibodies, laboratory standards, pharmaceutical compounds, environmental samples, research reagents, buffers requiring frozen storage, quality control materials, and other frozen laboratory supplies maintained between -15°C and -25°C.

Applications requiring storage below -80°C, including stem cells, long-term tissue preservation, and cell banking, are better suited for dedicated ultralow freezers or cryogenic storage systems.

Refurbishment & Testing Process

Every VWR SCUCFS-0420 received by American Instrument Exchange undergoes a comprehensive inspection and performance evaluation before shipment. Our technicians verify temperature accuracy using calibrated digital probes, inspect the refrigeration system, test the thermostat, evaluate the door gasket and locking mechanism, inspect the storage drawers, replace worn components as necessary, and thoroughly clean the freezer before delivery.

Laboratories outfitting complete cold storage systems frequently purchase laboratory refrigerators, laboratory freezers, ultralow freezers, biosafety cabinets, and centrifuges from American Instrument Exchange.

Shipping & Installation Considerations

The VWR SCUCFS-0420 ships by freight from American Instrument Exchange. Before delivery, laboratories should verify available undercounter space, electrical service, doorway clearances, and adequate ventilation around the cabinet. Because this model is designed for freestanding installation, sufficient airflow around the sides and rear of the cabinet is essential for dependable long-term operation.
