Double-door laboratory freezers for professional deep-freeze storage

Double-door laboratory freezers are specifically designed for laboratories that need to store large quantities of samples, reagents or biological materials at defined sub-zero temperatures. The two-door design enables structured separation of different sample categories and minimizes temperature increase in the closed section when one door is opened. This contributes to the stability of storage conditions and energy efficiency.

These units are used in research institutes, university laboratories, hospitals, blood banks and the pharmaceutical industry. Wherever large volumes need to be stored under controlled deep-freeze conditions, double-door laboratory freezers offer a practical solution.

Technical features of the units offered

The available GRAM BioPLUS forced-air freezers operate at -25°C and are available in two volume variants: with 1270 liters and 1400 liters usable capacity. Both models feature an stainless steel interior and a white exterior surface. The units are equipped with 4 castors, which facilitates installation and positioning in the laboratory.

A key feature is the variable interior configuration, which enables flexible adaptation to different sample containers and storage requirements. The forced-air technology ensures uniform temperature distribution throughout the entire interior and prevents local temperature fluctuations.

Selection criteria for double-door laboratory freezers

When selecting a double-door laboratory freezer, the required volume should first be determined. This depends on the number and type of samples to be stored as well as the expected sample growth. Temperature requirements depend on the stored material: many biological samples, enzymes and reagents require temperatures between -20°C and -30°C.

Other important criteria are the interior design and the flexibility of the configuration. A variable interior configuration allows adaptation to different rack systems, boxes or sample containers. Mobility through castors can also be advantageous when laboratory spaces are frequently reconfigured. The choice between stainless steel and coated surfaces influences hygiene, cleaning effort and longevity.

Fields of application and uses

Double-door laboratory freezers are used in molecular biological research, clinical diagnostics, microbiology and pharmaceutical development. They serve for the storage of DNA and RNA samples, proteins, antibodies, cell cultures, blood products, vaccines and temperature-sensitive chemicals.

In biobanks and sample archives, they enable long-term storage of large collections under controlled conditions. In quality control laboratories, reference materials and retention samples are stored safely. The two-door design supports organizational separation by projects, sample types or responsibilities.

Frequently asked questions about double-door laboratory freezers

Below we answer the most important questions regarding selection, use and operation of double-door laboratory freezers.

For which applications are double-door laboratory freezers particularly suitable?

Double-door laboratory freezers are ideal for laboratories with high sample volumes that require structured separation of different sample categories. They are suitable for biobanks, research institutes, clinics and pharmaceutical laboratories where large quantities of biological samples, reagents or temperature-sensitive substances need to be stored.

What temperature is required for storing biological samples?

The required storage temperature depends on the sample type. Many enzymes, antibodies and biological reagents are stored at -20°C to -30°C. The GRAM BioPLUS models offered operate at -25°C and thus cover a typical range for storing biological materials that do not require ultra-low temperature storage.

What does variable interior configuration mean for laboratory freezers?

A variable interior configuration enables flexible adaptation of shelves, drawers or holders to different sample containers and storage systems. This allows the use of various rack formats, cryoboxes or other storage systems and facilitates reorganization when requirements change in everyday laboratory use.

What advantages does forced-air technology offer?

Forced-air technology ensures uniform distribution of cold air throughout the entire interior. This prevents local temperature fluctuations and ensures all samples are stored under comparable conditions regardless of their position in the cabinet. This increases storage reliability and reproducibility of experimental results.

Why are some laboratory freezers equipped with castors?

Castors significantly facilitate positioning and realignment of the unit in the laboratory. This is particularly advantageous during renovations, cleaning work or reorganization of laboratory space. The GRAM models offered feature 4 castors that enable flexible installation despite the high weight.

How do the available models differ?

The two GRAM BioPLUS forced-air freezers offered differ in usable volume: model RF1270 offers 1270 liters, model RF1400 offers 1400 liters storage capacity. Both operate at -25°C, feature a stainless steel interior, white exterior surface, 4 castors and variable interior configuration.

Where can I obtain advice on selecting the appropriate unit?

For expert advice on selecting the suitable double-door laboratory freezer, you can contact specialized laboratory equipment suppliers. They will consider your specific requirements regarding volume, temperature, interior configuration and other parameters and support you in deciding on the appropriate model.
