Where it works

From micro tubes at high force to bottles at low speed, on one bench.

Molecular biology

DNA and RNA extraction in micro tubes at up to 30,642 × g, chilled to protect nucleic acids.

Protein work

Clarify cell lysates and precipitate proteins in 5 to 100 ml angle rotors.

Clinical samples

Switch to a swing rotor for blood collection tubes, conical tubes and bottles up to 750 ml.

Cell culture

Harvest and wash cells at low speed, then move to high speed without changing machines.

Which rotor type?

Pick the type by what you need at the end of the run.

Angle rotor

Tubes sit at a fixed angle. The fastest option; the pellet forms on the tube wall.

Swing rotor

Buckets swing out level. A flat pellet at the bottom; best for blood, layers and large volumes.

Engineered for every run

What happens inside the machine, from the first press of Start to the final spin-down.

Control and programs

Set speed or force, time and temperature on one screen, and recall stored methods so every run is repeatable.

  • LCD touch screenClear status and set-up
  • 3 run modesProgram, curve or preset
  • rpm ⇄ × gConverted in real time
  • 9 up / 10 downAcceleration and braking levels

Drive and cooling

An imported compressor with CFC-free R404A refrigerant holds the set temperature at up to 21,000 rpm, and shuts down within 3 minutes once the lid opens.

  • R404A coolingCFC-free; stops 3 min after lid opens
  • Silicone seal ringMeets GMP requirements

Safety

Imbalance, lid and overspeed protection work together, and automatic rotor recognition caps speed at each rotor's limit.

  • Imbalance, lid, overspeedThree layers of protection
  • Rotor recognitionSpeed limit set per rotor
r ≈ 62n

Speed or force: know the difference

Protocols are written in × g because force, not speed, does the separating. The same rpm gives more force in a larger rotor.

RCF = 1.118 × 10−6 × r × n²r = radius in mm · n = speed in rpm

Example: the 12 × 1.5/2.2 ml rotor at 21,000 rpm, r ≈ 62 mm, gives 30,642 × g.

Rotors

13 rotors in 2 types. Every bucket and adapter is shown with the rotor it fits.

Angle rotors

Fixed-angle rotors reach the highest speed and force. Choose by tube size; adapters fit smaller tubes.

Quick answers

The questions buyers ask most.

Can one machine handle micro tubes and large bottles?

Yes. Angle rotors run micro and conical tubes up to 21,000 rpm; swing rotors take up to 4 × 750 ml at 4000 rpm.

Which rotor for blood collection tubes?

Use a swing rotor with vacuum-tube adapters, for example 4 × 24 × 5/7 ml in the 750 ml buckets.

Should I set rpm or × g?

Either. The centrifuge converts between them in real time for the fitted rotor.

What power supply does it need?

AC 220 V, 50 Hz, 20 A circuit, 1.5 kW.
