Centrifuge capacity is often compared by maximum millilitres per run. That number describes the rotor envelope, but it does not tell a laboratory how many real samples can be completed during the busiest part of the day.
A useful capacity plan starts with peak workload, actual vessels per run, full cycle time, protocol concurrency and acceptable downtime.
These variables determine whether one larger centrifuge, two parallel units, or a main centrifuge plus a dedicated secondary unit is the more efficient equipment architecture.
Maximum capacity, maximum speed and maximum RCF describe equipment capability. Throughput describes how many usable samples the laboratory can actually complete in a defined period. The two should not be treated as the same metric.
The period most likely to create a queue determines whether the installed centrifuge capacity is sufficient.
A laboratory processing 400 samples per day can have very different equipment needs depending on how those samples arrive.
If the workload is distributed evenly across an eight-hour day, a moderate-capacity platform may be sufficient. If 250 samples arrive within a two-hour morning window, the same daily volume creates a much higher peak processing requirement.
Capacity planning should therefore record daily volume, peak-window volume and maximum acceptable waiting time as separate values.
A rotor described as 1200 mL does not automatically tell a buyer how many real laboratory samples it can process. Tube, bottle, bucket and adapter combinations determine the usable batch size.
Clinical laboratories may need to know how many blood collection tubes can be processed in one run. Research laboratories may care about the number of 15 mL or 50 mL conical tubes. Cell-processing workflows may instead use bottles or larger vessels.
For capacity planning, the more useful value is: actual vessels per run using the intended rotor and adapter.
Two protocols requiring different centrifugal force cannot occupy the same machine at the same time even if rotor capacity remains available.
A long protocol can block shorter workflows and create queues unrelated to nominal rotor capacity.
Refrigerated and ambient workflows may create separate operating requirements during the same peak window.
Routine batches can occupy a large centrifuge when an urgent or short-spin sample needs immediate access.
Appropriate when sample type, protocol and arrival pattern are highly standardized and larger batches can be accumulated without delaying the workflow.
Appropriate when continuous arrivals, multiple protocols or uptime requirements make simultaneous processing more valuable than the largest possible single batch.
Appropriate when one workflow represents most of the sample volume, while a smaller proportion requires special vessels, refrigeration, microtubes, plates or rapid priority access.
The useful comparison is not simply small versus large. Different GlanLab platforms support different combinations of batch size, rotor flexibility, temperature control and installation requirement.
A useful reference for laboratories needing a flexible medium-capacity platform. YT5AR adds refrigerated operation where temperature-controlled workflows are required.

A broad rotor platform covering microtube, PCR, larger tube, microplate and higher-capacity configurations. It is relevant where several workflows need to share one centrifuge platform.

A refrigerated floor-standing platform for larger batches, with fixed-angle, swing and microplate rotor options.

|---|---|---|
| Equipment | One primary instrument | Multiple instruments |
| Rotor / Adapter | More centralized | Some configurations may need duplication |
| Space | May require more floor space for a large platform | May require additional bench positions |
| Electrical | Higher requirement may be concentrated in one installation | Demand is distributed across several instruments |
| Maintenance | One equipment system | More service points |
| Downtime | Greater single-point-of-failure risk | Remaining units can preserve partial capacity |
| Batch efficiency | Strong when large uniform batches are available | Strong when workload can be divided or arrives continuously |
| Idle capacity | Large rotor may run partially loaded during quiet periods | Only the number of units required can be used |
Provide the sample vessel, daily and peak sample volume, required RCF, full cycle time, temperature requirements, simultaneous protocols, available space and acceptable downtime. GlanLab can then compare large-capacity, parallel and mixed-platform configurations.
