VWR SCBAF-2020 General Purpose Laboratory Freezer Overview

The VWR SCBAF-2020 is designed for laboratories that need dependable frozen storage without the complexity of specialty or ultralow temperature equipment. Its large upright cabinet provides organized storage for frequently accessed laboratory materials while maintaining consistent temperatures appropriate for many routine laboratory applications.

Unlike residential or commercial freezers, laboratory freezers are engineered to provide more consistent temperature control, durable construction, and features such as locking doors, alarm systems, and digital temperature monitoring. These characteristics help laboratories protect valuable samples while supporting regulatory compliance and good laboratory practices.

Common Applications

The VWR SCBAF-2020 is commonly used to store laboratory reagents, biological specimens, vaccines, pharmaceutical products, enzymes, antibodies, buffers, quality control materials, clinical samples, environmental samples, and other laboratory materials requiring dependable storage at approximately -20°C.

Its generous storage capacity also makes it a practical choice for laboratories replacing aging commercial freezers with equipment designed specifically for scientific environments.

Ideal Laboratory Types

The SCBAF-2020 is well suited for biotechnology laboratories, pharmaceutical facilities, hospital laboratories, clinical laboratories, academic research institutions, environmental testing laboratories, public health organizations, industrial quality control laboratories, and government research facilities.

Its combination of large storage capacity, dependable performance, and straightforward operation makes it an excellent choice for laboratories seeking reliable day-to-day frozen storage.

Temperature Recovery & Uniformity

Maintaining stable temperatures during routine laboratory use is essential for preserving sample integrity. The SCBAF-2020 utilizes a laboratory-grade refrigeration system designed to provide consistent cabinet temperatures while recovering efficiently following normal door openings.

Because the freezer features a manual defrost system, stored materials are not exposed to the periodic warming cycles associated with many automatic defrost freezers. This allows laboratories to maintain stable storage conditions while scheduling defrost maintenance at convenient intervals.

Typical Stored Materials

The VWR SCBAF-2020 is commonly used to store:

Vaccines
Biological specimens
Laboratory reagents
Enzymes
Antibodies
Laboratory buffers
Pharmaceutical compounds
Diagnostic reagents
Quality control materials
Environmental testing samples
Clinical specimens

Materials requiring storage below -40°C or long-term preservation at ultralow temperatures should instead be stored in an appropriate ultralow temperature freezer.

Testing Procedures for Used and Refurbished Laboratory Freezers

Cold Storage Reliability from American Instrument Exchange

At American Instrument Exchange, every used and refurbished laboratory freezer we offer undergoes a comprehensive multi-point testing protocol to ensure optimal performance, temperature stability, and long-term reliability. Our rigorous testing procedures are designed to meet the demanding standards of biomedical, pharmaceutical, research, and clinical environments—so you can trust your freezer to protect your valuable samples and materials.

Why Testing Refurbished Laboratory Freezers Is Critical

Before any laboratory freezer is placed back into service, it must be carefully tested for:

Consistent temperature control and uniformity across internal zones
Compressor functionality and refrigeration system performance
Seal integrity and insulation efficiency to prevent temperature loss
Electrical safety and alarm system operation

Thorough testing minimizes the risk of temperature excursions, equipment failure, and product loss—especially for temperature-sensitive items like reagents, biological samples, and vaccines.

Our structured testing protocol ensures that all used and refurbished laboratory freezers meet or exceed manufacturer specifications and industry expectations.
