The Thermo Scientific HAEMAFlex 6 and HAEMAFlex 8 swing-out rotors are dedicated windshielded swinging bucket rotors for the Cryofuge 8 blood bank centrifuge. Moreover, both rotors feature Eco-Spin technology for energy savings of up to 64 percent. In addition, these rotors reach RCF values of 7,295 x g and 7,144 x g respectively. As a result, you process blood bags efficiently on one shared bucket system.
Furthermore, you choose between the HAEMAFlex 6 for 6 x 550 mL blood bags and the HAEMAFlex 8 for 8 x 550 mL. Therefore, your rotor adapts to your throughput needs without changing the bucket system. Moreover, you can later upgrade easily from the HAEMAFlex 6 to the HAEMAFlex 8 using the same buckets and adapters. Additionally, this flexibility offers a future-proof investment for growing blood banks.
In addition, both rotors support four bucket configurations with more than ten adapter options. Subsequently, you process single, double, triple, quad or quint blood bags ranging from 250 to 550 mL. Moreover, this rotor also offers adapters for platelet-rich plasma (PRP) and buffy coat bags of 250 mL. As a result, you combine blood separation, plasma processing and component isolation in a single rotor.
Finally, the windshielded design with Eco-Spin technology provides substantial energy savings. Therefore, these rotors consume up to 64 percent less energy than comparable non-windshielded rotors. As a result, you reduce not only operational costs but also the environmental impact of the blood bank laboratory.

Order three sets of bucket and adapter for use with the HAEMAFlex 6 rotor and four sets for use with the HAEMAFlex 8 rotor.
Windshielded swing-out rotors for the Thermo Scientific Cryofuge 8 blood bank centrifuge. The HAEMAFlex 6 offers 6 x 550 mL at 7,295 x g RCF and the HAEMAFlex 8 offers 8 x 550 mL at 7,144 x g RCF. Both rotors feature Eco-Spin technology for up to 64 percent energy savings. Suitable for blood separation, plasma processing and component isolation via four bucket configurations.








The HAEMAFlex 6 and HAEMAFlex 8 are both compatible with the Thermo Scientific Cryofuge 8 blood bank centrifuge. Moreover, the HAEMAFlex 6 reaches a maximum speed of 5,000 rpm and 7,295 x g. In addition, the HAEMAFlex 8 reaches a maximum of 4,600 rpm and 7,144 x g. As a result, you choose between higher speed or larger capacity on the same platform.
The HAEMAFlex 6 offers a capacity of 6 x 550 mL and reaches 7,295 x g, whereas the HAEMAFlex 8 offers a capacity of 8 x 550 mL and reaches 7,144 x g. Moreover, both rotors work with the same bucket system. Therefore, you can upgrade easily from the HAEMAFlex 6 to the HAEMAFlex 8 without purchasing new buckets. In addition, choose the HAEMAFlex 6 for regular to medium throughput and the HAEMAFlex 8 for maximum capacity.
Eco-Spin is the windshielded technology of Thermo Scientific in which the rotor has a sealed aerodynamic housing. Therefore, the rotor experiences less air resistance during rotation. Moreover, this technology saves up to 64 percent energy compared to comparable non-windshielded rotors. As a result, you reduce both operational costs and the environmental impact of the blood bank laboratory.
For the HAEMAFlex 6 and HAEMAFlex 8, four bucket types are available: oval single, single with filter pack, single round and the standard configuration. Moreover, each bucket type offers multiple adapter options for blood bags from 250 to 550 mL. In addition, you process single, double, triple, quad and quint blood bags via dedicated adapters. Furthermore, dedicated adapters are available for platelet-rich plasma (PRP) and buffy coat bags.
For the HAEMAFlex 6, you order three sets of bucket and adapter (6 buckets total). Conversely, for the HAEMAFlex 8, you order four sets of bucket and adapter (8 buckets total). Moreover, all buckets and adapters are sold in sets of two. As a result, you configure the rotor based on your specific blood bank application.
Yes, the HAEMAFlex 6 and HAEMAFlex 8 are designed for clinical blood bank applications on the Cryofuge 8 centrifuge. Moreover, the Cryofuge series complies with the European IVDR directive for in-vitro diagnostics. In addition, this configuration supports regular blood separation, plasma processing and component isolation. As a result, these rotors are ideal for accredited blood banks and transfusion centres.
