Microcentrifuge with PCR Plate and Strip Rotor

What is the Microcentrifuge with PCR Plate and Strip Rotor?

A microcentrifuge with PCR plate and strip rotors spins 96-well PCR plates, 8-strip tubes and 0.2 mL tubes at up to 2,000 to 3,000 x g. It is used in qPCR and sequencing library workflows to remove bubbles and collect liquid before thermal cycling.

Overview

PCR workflows rely on consistent liquid volumes and bubble-free wells, and this variant is built for that purpose. Plate rotors hold one or two 96-well PCR plates in swing-bucket carriers, while strip rotors hold 8 to 16 8-strip tubes. Maximum speed is about 3,000 to 6,000 rpm, corresponding to 1,000 to 3,000 x g, enough to collect volumes from walls and lids and dislodge bubbles. Electronic controls set speed and time from 10 seconds to 99 minutes, and acceleration or deceleration profiles prevent splashing in 10 microliter reactions. Some units accept deep-well plates, microtiter plates and sealing film. Low-profile chambers fit on crowded benches. Because samples are sealed with optical film, rotor seals for biohazards are less common. The unit typically weighs 6 to 12 kg.

How does it work?

A microcentrifuge spins a small, lightweight rotor directly coupled to a brushless DC motor, reaching top speed in 10 to 30 seconds. Fixed-angle rotors hold tubes at 45 degrees, which shortens the sedimentation path and gives rapid pellet formation on the tube wall. The rotor is made of aluminum or engineering plastics and has a sealed lid option for biosafety. RCF equals 1.118 x 10^-5 times rotor radius in centimeters times rpm squared, and most models let the user enter either value. Short-spin or pulse functions run while a key is held. An imbalance sensor and lid lock stop the motor if the load is uneven or the lid opens. Refrigerated versions add a compact compressor. PCR strip rotors and colored tube adapters handle small sample formats.

What are the key features?

• Swing-bucket plate rotor holds one or two 96-well PCR plates
• Strip rotor accommodates 8 to 16 8-strip tubes or 0.2 mL tubes
• Acceleration profiles prevent splashing of small reaction volumes
• Low-profile chamber fits on crowded benches next to thermal cyclers
• Adjustable speed and time set from 10 seconds to 99 minutes

What are the technical specifications?

A typical microcentrifuge with pcr plate and strip rotor configuration offers maximum speed of 3,000–6,000 rpm, maximum RCF of approx. 1,000–3,000 x g, plate capacity of 2 x 96-well PCR plates, strip capacity of 8–16 x 8-strip tubes, timer range of 10 s–99 min and acceleration profiles of 3–9 selectable. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Microcentrifuge with PCR Plate and Strip Rotor is used in qPCR plate preparation, sequencing library preparation, bubble removal from reaction plates and high-throughput sample collection. Across the wider Microcentrifuges class, laboratories also deploy it for DNA and RNA spin-column purification, PCR tube pulse spins and protein precipitation.

Which standards and certifications apply?

Relevant standards and methods include IEC 61010-1, IEC 61010-2-020, IEC 61326-1, ISO 15189, CLSI MM13 and GB 4793.1. Certification candidates for this model are CE, ISO 9001 manufacturing and RoHS; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Keep the lid clean and free of residue, since dried sample or salts can cause rotor corrosion and imbalance. Wipe the chamber and rotor with 70 percent ethanol or mild detergent, and autoclave rotors only if rated. Tubes should be balanced in opposing positions, with matched volumes and tube types. Inspect the rotor for cracks, pitting or deformation at least every six months and retire it at the stated lifetime. Verify speed and timer annually with a tachometer. Keep aerosol-tight lids closed when handling pathogens. Place the unit on a flat bench away from edges, because vibration can cause walking during unbalanced runs.

How do I select the right Microcentrifuge with PCR Plate and Strip Rotor?

Choose this variant for plate-based PCR and library workflows, not for pelleting or precipitation. It differs from tube-based siblings by rotor geometry and lower RCF. In the RFQ, list plate and strip formats, including skirt type and height, and any need for deep-well plate compatibility.

How does it compare with other Microcentrifuges variants?

Choose by RCF first: spin-column work typically needs 10,000 to 14,000 x g, while RNA and protein precipitation often calls for 12,000 to 21,000 x g. Decide whether refrigeration is necessary; ambient models suffice for DNA spin columns and quick spins, but RNA, enzymes and long spins benefit from 4 C. Rotor capacity matters, with 12, 24 and 30 tube positions common. Look for interchangeable rotors, aerosol-tight lids, PCR strip adapters, programmable timers, and quiet operation below 55 dB(A). For high-throughput settings, consider units accepting 96-well plates or PCR strips. Verify that tubes are rated for the RCF and confirm the unit is compact enough for shared benches and biosafety cabinets.
