Hettich EBA 270 centrifuge – 6 × 15 ml with swing-out rotor
The Hettich EBA 270 is a compact laboratory centrifuge for physician offices, small laboratories and clinical sample preparation. Its integrated 6-place swing-out rotor accepts tubes up to 15 ml, swings out to 90° and operates from 500 to 4,000 rpm with a maximum RCF of 2,254 × g.
Hettich lists standard blood collection tubes and urine tubes up to 15 ml as typical applications. According to the manufacturer, the 90° swing-out rotor is particularly suited to blood collection tubes containing separating gel.

Why the design determines the separating layer
Rotor designs guide the vessels differently during operation. The illustration shows the geometric difference between swing-out and angled rotors. Select a design.
During operation, the tube swings out to 90°. Centrifugal force then acts upon it. along the tube axis, and the boundary between the phases forms exactly perpendicular to it. If the tube is then positioned vertically again, this boundary is already in place. horizontal Nothing needs to flow back, nothing gets smudged. How individual samples appear after the run also depends on the sample, container, rotational speed, and runtime.
In an angle rotor, the tube remains at a fixed angle. Centrifugal force acts upon it. oblique to the tube axisThe heavy phase adheres to the outer wall during operation, with the interface positioned perpendicular to the tube. As soon as the rotor stops and only gravity is acting, The deposited material runs back down the wall.until the boundary is horizontal again. The extent to which this rearrangement affects a specific sample depends on the sample, the container, the rotational speed, and the runtime.
Schematic representation of the physical principle. Which phases form and how sharply they separate depends on the sample, rotational speed, and transit time.
Interactive · Loading
Six seats, but not every booking works.
A rotor must be loaded symmetrically, otherwise the imbalance detection will deactivate – and in the worst case, the bearing will be damaged. Tap the slots you want to fill.
No seat occupied
Select the seats you want to fill. The computer checks whether the numbers cancel each other out.
Opposite seats: 1–4, 2–5, 3–6
The geometric symmetry is checked. Additionally, opposite positions must be loaded with the same mass according to the manufacturer's instructions. Use identical container types and observe the specifications in the device manual.

Operation & Purpose
What needs to be clarified before the first run
Operational
Read the manual before first use. Operation by trained personnel only. Manual and data sheet are available for download below.
Load symmetrically. Use the same tubes, the same fill level, and place them opposite each other. Do not exceed the maximum fill level.
Only open the cover when the rotor has stopped. The lock only releases after that; the emergency release is intended for power outages, not for everyday use.
Set up securely. Level, load-bearing surface, safety distance all around according to the manual, grounded electrical outlet.
Protective equipment. Wear gloves and safety goggles when handling biological material; do not allow any liquid to enter the centrifuge chamber.
After the run. Check the centrifuge chamber and rotor, remove any breakage immediately, clean and disinfect according to the manual and hygiene plan.

Practical questions
Frequently Asked Questions
My protocol specifies × g – what speed should I set?
The calculator above will determine this. Background: The relative centrifugal acceleration depends on the rotor radius, which is why the same rotational speed results in different g-values on two different devices. For rotor 2315, the radius is 12.6 cm; 3,300 min⁻¹.−1 This results in approximately 1,534 × g. For other devices, the RCF/RPM calculator.
Why am I not hitting my target value exactly?
Because the rotational speed changes in increments of 100 rpm−1 The calculator can be adjusted. It therefore displays the nearest adjustable speed and the resulting calculated RCF value. The deviation depends on the selected target value.
What distinguishes a swing-out rotor from an angled rotor?
In a swing-out rotor, the vessels move to a horizontal position during operation; in an angled rotor, they remain at a fixed angle. The graphic above illustrates the geometric principle. The separation achieved with a specific sample also depends on the sample, the vessel, the rotational speed, and the runtime.
Which tubes are intended for the EBA 270?
Hettich lists standard blood collection tubes and urine tubes up to 15 ml. According to the manufacturer, the integrated 90° swing-out rotor is particularly suited to blood collection tubes containing separating gel. Compatibility of a specific tube depends on dimensions, adapters and the manufacturer’s specifications.
How should the 6-place rotor be loaded correctly?
The rotor must be loaded geometrically symmetrically and with equal mass in accordance with the manufacturer’s instructions. The device manual, rotor loading plan and the specifications for the tubes and adapters used are decisive.
How is the EBA 270 classified for regulatory purposes?
Hettich classifies the EBA 270 as a Class A in vitro diagnostic device under Regulation (EU) 2017/746. Its intended purpose covers sample preparation in in vitro diagnostic procedures. For other uses, the intended purpose of the system being used is decisive.
How loud is the Hettich EBA 270?
Hettich specifies a maximum noise level of ≤ 51 dB(A). The dimensions are 326 × 400 × 239 mm and the weight is approximately 14 kg.
Which settings is the Hettich EBA 270 designed for?
Hettich lists small laboratories and physician office laboratories as typical settings. The EBA 270 is a compact centrifuge intended for sample preparation in in-vitro diagnostics; the specific use must match the manufacturer’s intended purpose and the tubes being used.
What is included in the delivery?
