Should your lab pay more for a refrigerated centrifuge, or is a non-refrigerated model enough? This is one of the most common questions in centrifuge purchasing. The wrong choice can increase cost, slow down workflow, or fail to match temperature-sensitive samples.
The answer depends on your sample type, run speed, run time, target temperature and daily workload. A refrigerated model is useful when temperature control matters. A non refrigerated centrifuge is more economical when the workflow is short, routine and performed at room temperature.
This guide compares refrigerated vs non refrigerated centrifuge options from a practical buying perspective, helping labs avoid overbuying while still protecting workflows that genuinely need cooling.
A refrigerated centrifuge controls chamber temperature during centrifugation. Its main value is not that it is “more advanced,” but that it supports workflows where temperature is part of the protocol.
For labs working with proteins, enzymes, cells, blood components or molecular biology samples, controlled temperature may be necessary depending on the SOP and reagent requirements.
During centrifugation, rotor movement and air friction may increase chamber temperature. For short routine spins, this may not matter. For long runs, high-speed operation or temperature-sensitive samples, heat build-up can become a workflow risk.
This is why cooling should be judged by actual running conditions, not by equipment appearance or catalog positioning.
Refrigeration does not mean every sample is automatically safer. If the protocol does not require low-temperature centrifugation, a non-refrigerated model may be enough.
The correct decision starts with one question: does your sample or protocol require controlled temperature during centrifugation?
Protein and enzyme-related workflows are often more temperature-sensitive. Some protocols require low-temperature centrifugation to support sample handling or maintain activity during processing.
This does not mean every protein or enzyme sample must use a refrigerated centrifuge. The final decision should follow the protocol, reagent instructions and laboratory SOP.
Molecular biology workflows may also require temperature control, especially RNA-related work, nucleic acid extraction or reagent-sensitive preparation. Many of these workflows use microtubes, spin columns or small-volume tubes.
For labs mainly handling microtube-based DNA/RNA preparation, a micro centrifuge may be enough if cooling is not required. If the protocol requires low temperature, a refrigerated model should be considered.
Cell pellets, plasma, serum and certain blood components may also need controlled temperature depending on the application. Some workflows can be performed at room temperature, while others need cooling.
Before choosing a centrifuge, confirm sample type, tube type, required RCF, spin time and temperature requirement.
A non refrigerated centrifuge is often enough for short spins, low-speed separation and room-temperature workflows. If the sample is not temperature-sensitive and the run time is short, refrigeration may not provide clear value.
Examples include simple clarification, routine tube separation and basic teaching laboratory work.
Non-refrigerated centrifuges are usually more economical, easier to maintain and simpler to operate. They have fewer cooling-system components, which can reduce maintenance concerns.
For labs with limited budgets or basic sample processing needs, a non-refrigerated model may be the better purchasing decision.
Do not buy a refrigerated model only because it sounds more professional. If the protocol does not require cooling, the lab may spend more on equipment, power use and maintenance without improving workflow.
When buying a refrigerated centrifuge, do not only look at the lowest temperature in the catalog. The key question is whether the machine can maintain the required temperature during your actual run.
Buyers should confirm temperature range, control accuracy, rotor compatibility, room temperature conditions and performance during expected speed and run time.
Some workflows require the chamber and rotor to be cooled before samples are loaded. In this case, pre-cooling becomes important.
Before buying, ask whether the centrifuge supports pre-cooling, how long it takes to reach the target temperature and whether the rotor can remain at the required temperature before operation.
The longer and faster the run, the more important temperature control may become. High-speed operation can increase heat generation, especially in molecular biology, protein processing or other temperature-sensitive workflows.
If your lab often performs long high-speed runs, a high speed centrifuge with refrigerated options may be more suitable than a standard room-temperature model.
A refrigerated centrifuge usually costs more because it includes a compressor, cooling system and temperature control components. This cost is justified when temperature control is required, but unnecessary for many short routine workflows.
Cooling systems require more attention. Buyers should consider ventilation space, dust cleaning, compressor condition, cooling efficiency, noise and heat dissipation.
These points are not reasons to avoid refrigerated centrifuges. They are practical factors that should be included in the purchasing decision.
Room temperature, airflow and bench space can affect cooling performance. The machine should be placed in a suitable environment with enough ventilation.
International buyers should also confirm voltage, plug type, frequency, warranty, spare parts and after-sales support.
Sample / Process | Temperature Sensitivity | Run Speed / Time | Cooling Need | Suggested Type |
Routine short spin | Low | Low speed / short time | Usually not necessary | Non refrigerated centrifuge |
Serum / plasma separation | Depends on SOP | Low to medium speed | Depends on protocol | Non-refrigerated or refrigerated |
Protein preparation | Medium to high | Medium/high speed or longer run | Often needed if protocol requires low temperature | Refrigerated centrifuge |
Enzyme-related samples | High | Depends on protocol | Often considered | Refrigerated centrifuge |
RNA-related workflows | Medium to high | Microtube / high-speed steps | Depends on protocol | Refrigerated micro centrifuge |
Cell pellets / components | Medium to high | Depends on sample | Often considered | Refrigerated centrifuge |
High-speed long run | Higher heat risk | High speed / long time | Often recommended | High speed refrigerated centrifuge |
Budget routine lab work | Low | Short routine operation | Usually not necessary | Non refrigerated centrifuge |
This table is a buying guide, not a universal protocol. The final choice should follow sample requirements, reagent instructions, tube type and laboratory SOP.
Do not only ask for the price of a refrigerated centrifuge. First tell the supplier what samples you process, such as proteins, enzymes, DNA/RNA samples, cells, blood components or routine laboratory samples.
This helps the supplier judge whether cooling is necessary.
The supplier needs to know required RPM or RCF, run time, target temperature, tube type, rotor type and number of samples per run.
If pre-cooling is required, mention it clearly. If the run is long or high-speed, this information is especially important.
For international orders, confirm voltage, frequency, plug type, cooling system, warranty, spare parts, manual and after-sales support.
A refrigerated centrifuge depends more on cooling performance and technical support than a simple non-refrigerated model.
A good recommendation should not always push the more expensive option. If your workflow does not require cooling, a non-refrigerated centrifuge may be more practical.
A refrigerated centrifuge is the right choice when your samples or protocols require temperature control during centrifugation. It is especially useful for temperature-sensitive workflows, long runs and high-speed operation.
However, in the comparison of refrigerated vs non refrigerated centrifuge, refrigerated does not always mean better. For routine short spins, room-temperature protocols and budget-sensitive labs, a non-refrigerated model may be the smarter purchase.

A refrigerated centrifuge controls chamber temperature during centrifugation. A non refrigerated centrifuge usually runs near ambient conditions and may warm during operation.
No. It depends on sample sensitivity, run speed, run time and protocol. Routine short spins may not need cooling.
It is often considered for temperature-sensitive proteins, enzymes, RNA-related workflows, cells, certain blood components, long runs or high-speed operation.
For simple, short and room-temperature workflows, a non refrigerated centrifuge may be more economical and easier to maintain.
