A laboratory centrifuge is often replaced because the equipment is ageing, faults are becoming more frequent, support is becoming difficult, or the current platform no longer fits the laboratory's requirements.
The replacement does not necessarily need to change the established method. The better starting point is to identify the conditions that the new centrifuge must continue to support: sample vessel, rotor, RCF, capacity, temperature and operating conditions.
Once these are defined, the replacement can be evaluated as a compatibility project rather than simply choosing another machine with a similar name or RPM.
Not every specification of the old centrifuge needs to be reproduced. Separate the requirements into three groups before comparing replacement equipment.
Sample vessel, required RCF, operating time, temperature and the practical batch capacity needed by the existing workflow.
Rotor compatibility, adapter requirements, acceleration and deceleration, chamber dimensions, installation space and electrical requirements.
Additional vessel formats, higher capacity, refrigeration or a wider rotor range when the laboratory has actually outgrown the old platform.
The centrifuge body is only one part of the operating system. The rotor determines how the sample vessel is positioned, how many vessels can be processed and, together with rotor radius and speed, the centrifugal force.
RPM tells you how fast the rotor turns. RCF describes the relative centrifugal force applied to the sample. Because rotor radius is part of the relationship, two centrifuges running at the same RPM can produce different RCF values.
For a replacement project, the most useful information is the RCF required by the existing method. If only RPM is recorded, provide the old centrifuge model and rotor information as well.
The selected replacement rotor must be evaluated at its own rated speed and RCF. The maximum specification of the centrifuge itself should not be treated as the operating limit of every available rotor.
A replacement is successful when the complete working configuration still makes sense, not simply when the new machine has similar headline specifications.
| Existing condition | What to record | Replacement question |
|---|---|---|
| Sample vessel | Tube, bottle, plate, volume and dimensions | Can the new rotor physically support the same vessel? |
| Rotor | Type, model, capacity and speed rating | Is there a compatible rotor, or is a new rotor required? |
| RCF | Required ×g from the method | Can the selected rotor reach the required force? |
| Capacity | Actual vessels processed per run | Will the replacement maintain the required batch size? |
| Time | Spin time and relevant handling time | Does the replacement support the operating cycle? |
| Temperature | Required operating temperature | Is a refrigerated configuration necessary? |
| Acceleration / deceleration | Whether the method depends on braking behaviour | Can the required profile be reproduced or appropriately assessed? |
| Installation | Available space, voltage and frequency | Can the new machine be installed without major changes? |
The right replacement may be a similar-capacity machine, a more flexible benchtop platform or a larger refrigerated system. The following GlanLab platforms illustrate three different replacement directions.
A practical starting point for replacement projects based around routine, medium-capacity work. The YT5A is non-refrigerated, while YT5AR provides a temperature range of −20°C to 40°C. The platform has multiple rotor configurations for tubes, microplates and larger vessels.
Review YT5A / YT5AR →
A stronger replacement option when the existing workflow covers several vessel sizes. Published rotor configurations include microtubes, PCR formats and larger tubes up to 100 mL. YT16R adds refrigerated operation from −20°C to 40°C.
Review YT16 / YT16R →
Relevant when the replacement project also needs larger batch capacity or refrigerated floor-standing operation. Published rotor options include 6 × 300 mL fixed-angle, 4 × 1000 mL swing and microplate configurations.
Review YF12R →A direct replacement is not always the best long-term decision. The laboratory may have changed since the original centrifuge was purchased.
In these cases, copying every specification of the old machine can preserve an outdated limitation. The better approach is to preserve the method-critical requirements while deliberately changing the equipment capabilities that no longer fit.
For a centrifuge replacement project, the most useful starting information is not simply the old machine's maximum RPM. Provide the existing rotor, vessel, required RCF, capacity, run time, temperature and installation conditions.
GlanLab can then assess the replacement around the actual working configuration and identify whether a direct replacement, a different rotor package or a higher-capacity platform is appropriate.
