Size and weight
Where it works
High force and large capacity for research and bioprocess labs.
Clarify large lysate volumes at high force before chromatography.
Plasmid and genomic DNA preparation, from micro tubes to 500 ml bottles.
Differential centrifugation to separate nuclei, mitochondria and membranes under steady cooling.
Collect cells or particles from litres of culture with high-capacity and continuous-flow rotors.
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.
Engineered for every run
What happens inside the machine, from the first press of Start to the final spin-down.
Control and programs
Speed or force, time, temperature and ramp profile are set together. Stored programs keep high-speed methods consistent across users.
- Digital LCDSimple, clear operation
- Essential controlsRotor, speed or × g, time, temperature
- 9 up / 9 downAcceleration and braking levels
- Economical choiceHigh speed without extras you do not need
Drive and cooling
A high-torque AC variable-frequency motor and a Tecumseh compressor with CFC-free R404A refrigerant hold temperature even at full speed.
- AC variable-frequency motorHigh torque, electronic lid lock
- Tecumseh R404A coolingCFC-free refrigeration
- Silicone seal ringMeets GMP requirements
Safety
Electronic lid lock plus overspeed, over-temperature and imbalance detection, each with an automatic alarm, for safe running at high force.
- 4 safety alarmsLock, overspeed, over-temperature, imbalance
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.
Example: the 24 × 1.5/2.2 ml rotor at 25,000 rpm, r ≈ 93 mm, gives 64,983 × g.
Rotors
9 rotors in 1 types. Every bucket and adapter is shown with the rotor it fits.
Two values: GL-25M / GL-21M.
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.
What is the difference between GL-25M and GL-21M?
GL-25M reaches 25,000 rpm and 64,983 × g and takes the 4 × 1000 ml rotor. GL-21M reaches 21,000 rpm and 50,400 × g, up to 6 × 500 ml.
How does it differ from the H2500R series?
The GL series uses a simpler digital LCD panel instead of a touch screen, at a lower price. Speed, force and cooling are the same class.
Are swing and continuous rotors available?
Yes. See the extra rotors list under Rotors, including continuous-flow and microplate rotors.
How is it delivered?
Duty paid (DDP). The crate is 889 × 960 × 1450 mm; net weight is 290 kg without rotor.
Free DDP shipping
Delivered duty paid, with no surprise import charges.
1-year warranty
Major defects under warranty are covered by a full refund or replacement.
30-day returns
