Microplate rotors

Parallel plate processing for high-throughput laboratories

Microplate rotors allow you to centrifuge multiple microplates or deep-well plates simultaneously in one run. Whether you are performing ELISA protocols, pelleting cells in cell culture plates, removing condensation from PCR plates or processing large numbers of samples in parallel: a microplate rotor delivers significant time savings and reproducible results. At Poly Temp Scientific we offer dedicated microplate rotors from Thermo Scientific and Fiberlite, with capacity up to 28 standard microplates or 8 deep-well plates per run.

A microplate rotor is a specialised centrifuge rotor designed to process multiple microplates or deep-well plates simultaneously. As a result, these rotors are indispensable in high-throughput screening, ELISA protocols, molecular biology, drug discovery and pharmaceutical research. In addition, they offer significant time savings compared to centrifuging individual tubes, because up to 28 plates or 8 deep-well plates can be processed per run. Therefore, these models are widely used in pharmaceutical R&D laboratories, clinical diagnostics, genomics facilities and cellular biology.

At Poly Temp Scientific we offer dedicated plate-rotors from Thermo Scientific and Fiberlite, perfectly matched to the Thermo Scientific X1, X4, S1 and S4 Series centrifuges. Furthermore, all our rotors feature Auto-Lock rotor exchange for fast, safe rotor swap without tools. In addition, most models come with optional ClickSeal biocontainment lids, certified by Public Health England (Porton Down, UK) or TÜV NORD CERT GmbH, for safe processing of biohazardous samples in 96-well or 384-well format.

For maximum capacity on the X4 and S4 Series we offer the HIGHPlate 6000 rotor, with capacity for 10 microplates per run at 6,168 x g. Additionally, the Fiberlite H3-LV is available, a carbon fiber microplate rotor that reaches up to 28 standard plates or 8 deep-well plates per run at 2,593 x g. This rotor is ideal for high-throughput screening and automation, where large numbers of plates need to be processed in parallel. For more compact setups on X1, S1, X4 and S4 models we supply the M-20, with capacity for 6 microplates per run at 2,272 x g.

In addition to these dedicated plate-rotors, several swing-out rotors also accept microplate carriers, allowing you to flexibly switch between tube and plate processing on the same rotor. The TX-1000 processes up to 24 plates per run via 4 carriers of 6 standard microplates each or 4 carriers of 2 deep-well plates each. The TX-750 offers 16 plates per run via 4 carriers of 4 standard microplates each, and the M10 (C Series) processes 4 standard plates or 2 deep-well plates per run. These rotors can be found in our swing-out rotors category.

Applications for microplate centrifugation

Plate-rotors are used for centrifuging cell culture plates after transfection or drug incubation, sedimenting cells after a wash step in ELISA protocols, collecting content after pipetting or dispensing, quick-spinning PCR plates to remove condensation and processing filtration plates or magnetic bead plates for nucleic acid isolation. Additionally, models with biocontainment lids enable safe processing of infectious samples in BSL-2 environments.

Frequently asked questions about microplate rotor

What is a microplate rotor?

It is a centrifuge rotor designed to process multiple microplates or deep-well plates simultaneously in a centrifuge. Instead of individual tubes, the plates are placed in dedicated holders or carriers, allowing you to centrifuge up to 28 standard 96-well plates in one run. Therefore, these rotors are essential in high-throughput screening, ELISA protocols and molecular biology where large numbers of samples are processed in parallel.

Which plate-rotor has the highest capacity?

The Fiberlite H3-LV has the highest capacity in our range, with 28 standard plates or 8 deep-well plates per run at 2,593 x g. This rotor is suitable for the X4 Series centrifuges and is ideal for high-throughput screening and automation. For applications requiring higher RCF values, the HIGHPlate 6000 offers capacity for 10 plates per run at 6,168 x g, also for the X4 Series.

Which rotor fits my Thermo Scientific centrifuge?

For the X4 and S4 Series we offer the HIGHPlate 6000 (10 plates), the Fiberlite H3-LV (28 plates) and the M-20 (6 plates). For the more compact X1 and S1 Series, only the M-20 is suitable. On the C Series compact centrifuges you can use the M10 swing-out rotor (4 plates or 2 deep-well plates). Additionally, swing-out rotors such as the TX-1000 (24 plates) and TX-750 (16 plates) accept microplate carriers for flexible plate processing.

What is the difference between a microplate rotor and a swing-out rotor with carriers?

A dedicated plate-rotor (such as the HIGHPlate 6000 or H3-LV) is specifically designed for plate processing and often offers higher plate capacity per run. A swing-out rotor with microplate carriers (such as the TX-1000 or TX-750) offers flexibility because you can use the same rotor for tubes and bottles. Therefore, the choice depends on your workflow: dedicated model for maximum throughput and plate volumes, swing-out variant with carriers for laboratories that process both plates and tubes.

Can I centrifuge deep-well plates in a microplate rotor?

Yes, most models support deep-well plates. The Fiberlite H3-LV processes 8 deep-well plates per run, while the HIGHPlate 6000 is designed for both standard and deep-well formats. Additionally, swing-out rotors with microplate carriers also accept deep-well plates: the TX-1000 processes 8 deep-well plates (2 per carrier), the TX-750 4 deep-well plates and the M10 (C Series) 2 deep-well plates per run. Always check the maximum plate height (typically 60 mm) before ordering.

What is the maximum RCF of a plate-rotor?

These rotors typically reach lower RCF values than fixed-angle rotors because the plate holders take up more space and the samples sit further from the rotor axis. The HIGHPlate 6000 delivers the highest RCF in our range with 6,168 x g on the X4 Series. The Fiberlite H3-LV reaches 2,593 x g and the M-20 delivers 2,272 x g. For most plate applications such as ELISA, cell culture and quick spins, these RCF values are more than sufficient.
