Thermo Fisher Centrifuges for Research & Clinical Workflows

Thermo Fisher (Thermo Scientific) centrifuges provide reliable separation across micro-volume prep, routine clinical work, and high-throughput lab workflows. This Collection page brings models, rotors/adapters, and compatible consumables together in one place—and, as an iRight distributor page, helps you evaluate options and request a quote quickly.

Thermo Fisher Centrifuges Overview & Iright Distributor Support

Modern lab and clinical protocols depend on accurate g-force, temperature control, and rotor compatibility. Here you’ll find micro, benchtop, and refrigerated units alongside compatible rotors and tubes, so you can map capacity and ×g ranges to your SOPs. iRight can assist with selection, documentation, and post-purchase support.

Centrifuges apply relative centrifugal force (RCF, ×g) to separate cells, blood components, nucleic acids, proteins, and microbes. Thermo Scientific units cover microvolume spins (e.g., Pico™ 17), versatile bench workhorses (e.g., Sorvall™ ST 8 series), and compact clinical units (e.g., Medifuge™) with biocontainment lid options and intuitive controls.

Centrifuge Use Cases: Cells, Blood, DNA & Microbiology

Different applications emphasize different parameters—RCF targets, tube formats, and whether you need refrigeration. Use this section to connect your sample type and throughput to an appropriate unit/rotor combination before you compare specs or SKUs.

For cell harvest and organelles, moderate ×g and gentle ramps protect viability; a benchtop centrifuge with fixed-angle rotors is typical. Serum/plasma prep benefits from swinging-bucket clarity with blood collection tubes. DNA/RNA precipitation and PCR cleanup favor microcentrifuges at up to ~21,000 ×g with airtight lids. Microbial pelleting often uses larger capacities and fixed-angle rotors for culture tubes or bottles. When available, set and read ×g (not RPM) because rotor radius changes the actual force applied.

Centrifuge Selection Guide: Capacity, RCF/RPM & Temperature

Once you know your sample and container, narrow choices by capacity per run, target ×g, and whether cold-sensitive materials require a refrigerated model. Remember that the same chassis can span multiple tasks when you swap rotors and adapters.

When protocols are specified in RPM, convert to RCF (×g) using rotor radius or use an RCF/RPM calculator/resource from Thermo Fisher so force remains consistent across rotors.

Model Families: Micro, Benchtop, Refrigerated & Floor Units

Below are concise snapshots of representative Thermo Scientific models and what they’re built to do. Use them as capability anchors, then match rotors and tubes in the next sections; detailed model pages and manuals carry full specifications.

• Microcentrifuges (e.g., Pico™ 17): Compact, fast, and purpose-built for 1.5–2.0 mL workflows, frequently supplied with a 24-place or 18-place rotor and safety lids. Excellent for nucleic acid and protein preps. 

• Benchtop general purpose (e.g., Sorvall™ ST 8 / ST 8R): Day-to-day workhorses accepting a wide range of rotors—swinging-bucket for blood tubes and plates, fixed-angle for pellets. ST 8R adds refrigeration for temperature-sensitive samples.

• Clinical compact (e.g., Medifuge™): Small footprint with the unique DualSpin™ hybrid rotor that switches between fixed-angle and swinging buckets, helpful for mixed tube formats in clinics and core labs.

Rotors & Adapters: Fixed-Angle, Swing-Bucket & Plate Options

Choosing the right rotor unlocks the instrument’s range. This section highlights popular Thermo Scientific rotor systems and adapters so you can align tube/plate formats with capacity and biocontainment where needed.

The TX-1000 4 × 1000 mL swinging-bucket rotor processes up to 4 L in a general-purpose footprint and accepts multiple adapter sets, including microplate carriers or 250 mL bottle adapters. This versatility lets one benchtop unit pivot between blood tubes, plates, and culture bottles.

Microcentrifuge rotors with ClickSeal™ biocontainment lids are available on Pico/MicroCL models for secure high-g spins of 1.5–2.0 mL tubes. For refrigerated micro spins, MicroCL 21R ships with a 24-place ClickSeal rotor.

Consumables Fit: Centrifuge Tubes, Bottles & Deep-Well Plates

Consumables affect recovery, clarity, and safety. Select tube materials and formats that match g-force, chemicals, and temperature. Standardizing on compatible, traceable tubes can simplify QC and audits across teams.

Thermo Scientific Nunc™ Conical PP Centrifuge Tubes are widely used with bench units and rotors—available in 15 mL and 50 mL, bulk or racked packaging. Representative catalog numbers include 339650 (15 mL, bulk) and 339653 (50 mL, racked). Documented options support sterile configurations and recyclable racks for traceability.

Tip: When a protocol states RPM only, convert to ×g for your installed rotor radius, or set ×g directly on models that support it to ensure consistent force across labs.

FAQs: RCF vs RPM, Serum Spin Settings, Biocontainment

Procurement often triggers the same technical questions. The brief notes below aim to reduce back-and-forth and speed internal approvals; consult manuals or application notes for method specifics.

1. RCF vs RPM—what should I follow?

Follow RCF (×g) because it controls the actual force on samples; RPM varies with rotor radius. Use Thermo Fisher conversion resources or calculators when method sheets list RPM. 

2. Do I need a refrigerated unit?

If your materials are temperature-sensitive (e.g., live cells, certain proteins/enzymes), choose a refrigerated model such as ST 8R to maintain sample integrity during longer spins. 

3. What is a biocontainment lid and when is it required?

ClickSeal™ biocontainment lids on micro rotors provide aerosol containment for high-g spins and are recommended when working with risk-bearing samples or when your safety plan requires sealed runs. 

4. Can I run plates in a benchtop centrifuge?

Yes—use swinging-bucket rotors with plate carriers or TX-1000 microplate adapters for proper support and drainage.
