The Thermo Scientific BIOShield 1000A swing-out rotor is a windshielded swinging bucket rotor for the X4 and S4 Series centrifuges. Moreover, this rotor features integrated biocontainment certified by TÜV NORD CERT. In addition, the BIOShield 1000A reaches a maximum speed of 6,000 rpm and an RCF of 7,164 x g. As a result, this rotor delivers the highest RCF in the swing-out segment.
Furthermore, the windshielded design enables higher speeds than open swinging bucket rotors. Therefore, the BIOShield 1000A consumes less energy per run than comparable rotor bodies. Moreover, the integrated windshield prevents aerosol formation during centrifugation. As a result, you process biohazardous samples safely without separate ClickSeal lids.
Additionally, the BIOShield 1000A supports fifteen different adapter configurations. Subsequently, you can run 250 mL bottles, 50 mL conical tubes, microtubes and blood collection tubes in a single rotor. Furthermore, this rotor accommodates up to 224 microtubes of 1.5/2 mL or 112 blood tubes of 5/7 mL per cycle. In addition, you combine high RCF with flexible sample processing.
Finally, you switch the BIOShield 1000A in just three seconds thanks to Thermo Scientific Auto-Lock rotor exchange. As a result, no tools are required for a rotor change. Moreover, you switch quickly between pelleting protocols, virus research or microbiology applications where high RCF and biocontainment are essential.

Windshielded swing-out rotor with integrated biocontainment for Thermo Scientific X4 and S4 Series centrifuges. With a maximum capacity of 4 x 250 mL and 7,164 x g RCF, the BIOShield 1000A delivers the highest RCF in the swing-out segment. Equipped with TÜV NORD CERT-certified biocontainment and SlideCoat surface treatment. Ideal for microbiology, virus research and pelleting applications where safety is essential.








The BIOShield 1000A is compatible with Thermo Scientific X4T, X4TR, X4FR, S4T, S4TR and S4FR Series centrifuges. For the X4 series, this rotor reaches a maximum speed of 6,000 rpm and 7,164 x g. In addition, the S4 series reaches a maximum of 5,300 rpm and 5,590 x g. As a result, the BIOShield 1000A is not compatible with X1 or S1 Series centrifuges.
The BIOShield 1000A is a windshielded rotor with integrated biocontainment, whereas the TX-1000 and TX-750 are open swinging bucket rotors with optional ClickSeal lids. Moreover, the BIOShield 1000A reaches 7,164 x g, considerably higher than the 4,122 x g of the TX-1000 and 4,816 x g of the TX-750. Therefore, choose the BIOShield 1000A when you combine high RCF with biocontainment, and the TX-1000 or TX-750 for larger volumes per run.
The BIOShield 1000A features a windshielded design in which the buckets rotate inside a sealed housing. Therefore, aerosols remain contained within the rotor during centrifugation. Moreover, this biocontainment certification is issued by TÜV NORD CERT in Germany. As a result, you process biohazardous samples safely without separate biocontainment lids per bucket.
For the BIOShield 1000A, fifteen adapter configurations are available. As a result, you can process 250 mL bottles, 100-150 mL open-top tubes, 50 mL conical or round-bottom tubes, 15 mL DIN tubes, blood collection tubes and 1.5/2 mL microtubes. In addition, this rotor offers dedicated adapters for urine tubes and Sterilin universal tubes. Furthermore, all adapters are sold in sets of four.
No, the BIOShield 1000A is delivered as a complete windshielded rotor (SKU 75003182) without adapters. Therefore, you order the required adapters separately based on your application. Subsequently, you choose from fifteen different adapter sets for various tube and bottle formats.
A windshielded rotor such as the BIOShield 1000A has a sealed aerodynamic housing. Therefore, this rotor experiences less air resistance during rotation. Moreover, the energy input remains lower at high speeds compared to open swinging bucket rotors. As a result, you save energy per run while achieving higher RCF values.
