VWR SCBMF-3020 General Purpose Upright Laboratory Freezer Overview
The VWR SCBMF-3020 is designed to provide dependable frozen storage for laboratories that require consistent performance without the complexity of specialty freezers. Its upright configuration makes organizing high sample volumes straightforward while providing easy access to stored materials during routine laboratory operation.
Unlike household freezers, the SCBMF-3020 incorporates features expected in laboratory environments, including digital temperature control, alarm systems, probe access for independent monitoring, remote alarm capability, and a locking door for sample security. These features help laboratories maintain dependable storage conditions while supporting quality assurance and good laboratory practices.
Common Applications
The VWR SCBMF-3020 is commonly used to store laboratory reagents, vaccines, biological specimens, enzymes, antibodies, pharmaceutical products, clinical samples, environmental samples, diagnostic materials, quality control standards, and other research materials requiring dependable frozen storage between -15°C and -25°C.
Its large interior capacity also makes it an excellent choice for centralized sample storage, departmental freezers, or laboratories replacing multiple smaller storage units with a single laboratory-grade freezer.
Ideal Laboratory Types
The SCBMF-3020 is well suited for biotechnology laboratories, pharmaceutical manufacturers, academic research facilities, hospital laboratories, clinical laboratories, environmental testing laboratories, industrial quality control facilities, public health organizations, and government research laboratories.
Laboratories seeking dependable frozen storage with generous capacity and straightforward operation will appreciate the freezer's practical design and laboratory-specific features.
Temperature Recovery & Uniformity
Reliable frozen storage depends on maintaining stable cabinet temperatures throughout daily laboratory operation. The SCBMF-3020 utilizes a forced-air laboratory refrigeration system designed to distribute cold air evenly throughout the storage chamber while recovering efficiently after routine door openings.
Because the freezer uses a manual defrost system, stored materials are not subjected to the periodic warming cycles associated with many frost-free freezers. Laboratories can instead schedule defrost maintenance when it best fits their workflow while maintaining consistent storage conditions during normal operation.
Typical Stored Materials
The VWR SCBMF-3020 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 ultralow temperature freezer.
