A-4-38 Rotor Configuration

The centrifuge is supplied with an A-4-38 rotor and adapters for blood collection tubes with diameters of 13 and 16 mm. This configuration allows compatible tubes to be used for sample preparation and separation procedures in laboratory research.

The actual number of tubes that can be accommodated, their length, maximum volume and permissible operating speeds must be verified according to the specific adapters and containers used. Dimensional compatibility does not automatically establish approval for clinical diagnostic applications.

Refrigeration System and Temperature Control

The 5702 R refrigerated centrifuge allows temperatures to be set between -9 °C and +40 °C. Standby cooling enables the refrigeration system to remain active during waiting periods, while the Fast Temp function is designed to reach the selected temperature quickly.

These features can support the handling of temperature-sensitive samples. The actual temperature reached by the samples also depends on the load, centrifugation duration, rotational speed and ambient conditions.

FAQ – Frequently Asked Questions

• What is the 5702 R refrigerated centrifuge with A-4-38 rotor used for?
The 5702 R refrigerated centrifuge is a laboratory instrument designed for sample preparation and separation through low-speed centrifugation. It is particularly suitable for cell culture applications and research laboratories processing low to medium sample volumes. Its configuration with an A-4-38 rotor and adapters for 13 and 16 mm blood collection tubes allows compatible containers to be used for controlled sample processing. During centrifugation, rotation generates centrifugal force, promoting the separation of sample components according to their physical characteristics and the selected operating conditions. The integrated refrigeration system provides an adjustable temperature range from -9 °C to +40 °C, which is useful when experimental protocols require temperature control. Two programmable memory buttons, adjustable acceleration and braking settings, and the Fast Temp function help organize frequently repeated procedures. The centrifuge is classified as a General Lab Product intended for scientific research. This classification does not automatically establish authorization for clinical diagnostic applications.

• Which tubes are compatible with the A-4-38 rotor of the 5702 R centrifuge?
The 5702 R centrifuge is supplied with an A-4-38 rotor and adapters for blood collection tubes with diameters of 13 and 16 mm. This configuration is designed to accommodate compatible containers for sample preparation and separation in laboratory research. However, tube compatibility cannot be determined by diameter alone. The tube length, bottom shape, material, filling volume and maximum permitted centrifugation speed must also be considered. Operators must follow the manufacturer's rotor balancing instructions and operating limits. The maximum number of tubes that can be processed simultaneously depends on the actual adapter configuration. In laboratories handling biological samples, selecting the correct tubes and accessories contributes to operational safety and procedural consistency. The presence of blood collection tube adapters does not automatically mean that the instrument is certified for clinical diagnostic use. Before starting a centrifugation procedure, the compatibility of the rotor, adapters and sample containers should always be checked against the manufacturer's technical documentation.

• What are the advantages of the refrigeration system in the 5702 R laboratory centrifuge?
The 5702 R refrigeration system provides an adjustable temperature range from -9 °C to +40 °C, offering greater flexibility than a non-refrigerated laboratory centrifuge. Temperature control is particularly valuable when handling biological samples that are sensitive to thermal variations or when experimental protocols specify defined operating temperatures. The Fast Temp function is designed to help the instrument reach the selected temperature quickly, while standby cooling allows the refrigeration system to remain active between centrifugation cycles. These features can improve the organization of laboratory workflows and support consistent sample preparation conditions. It is important to distinguish between the temperature selected on the instrument and the actual temperature reached by the sample. Sample temperature may vary depending on the load, rotational speed, cycle duration and ambient conditions. For temperature-sensitive research procedures, operators should verify the required parameters and evaluate actual performance under the intended operating conditions. The refrigeration system therefore provides useful control capabilities without guaranteeing that every sample will immediately reach the displayed temperature.

• What is the maximum speed of the 5702 R centrifuge, and how are acceleration and braking adjusted?
The 5702 R refrigerated centrifuge has a specified speed range of 100 to 4,400 rpm, with the actual maximum permitted speed depending on the installed rotor. Rotational speed should be selected according to the sample type, container, rotor and requirements of the laboratory protocol. In addition to speed adjustment, the 5702 R allows acceleration and braking settings to be modified. This capability is useful for procedures in which rapid changes in rotational speed could affect the distribution or separation of sample components. The instrument also includes two programmable memory buttons for storing the parameters of two standard centrifugation procedures, allowing frequently used settings to be recalled quickly. When evaluating separation performance, it is important to consider relative centrifugal force, expressed as RCF, which depends on both rotational speed and rotor radius. Consequently, rpm alone should not be considered a universal measure of centrifugation effectiveness. The maximum operating speed and permissible load must always comply with the specifications of the installed rotor and adapters.

• Is the 5702 R refrigerated centrifuge suitable for cell culture, biotechnology and pharmaceutical research laboratories?
The 5702 R refrigerated centrifuge is particularly suitable for laboratories performing cell culture procedures and processing low to medium sample volumes. Its relevant features include low-speed centrifugation, adjustable refrigeration from -9 °C to +40 °C, an A-4-38 rotor with adapters for 13/16 mm collection tubes and the ability to store two operating programs. Adjustable acceleration and braking settings allow operation to be adapted to specific experimental requirements, while standby cooling and the Fast Temp function support temperature management. The centrifuge can be considered for research applications in biology, biotechnology, life sciences and pharmaceutical research, provided that the samples and containers are compatible with the installed configuration. As a General Lab Product, its declared intended use is scientific research. Any application in regulated pharmaceutical processes requires a separate assessment of equipment suitability, qualification requirements and potential validation procedures. Clinical diagnostic approval or compliance certification under GMP or GLP standards must not be assumed solely from the equipment's technical characteristics or intended research use.
