Laboratory Centrifuge Series Manufacturer

Shanghai Qiujing Biochemical Reagent & Instrument Co., Ltd. manufactures the Laboratory Centrifuge Series inside a broader laboratory instrument portfolio that also covers pipetting, mixing, water baths, balances, photometers and pH measurement. The range runs from compact mini centrifuges built for rapid micro-volume spins through benchtop low-speed units for gentle pelleting to refrigerated micro-high-speed benchtop models used in molecular biology, clinical sample preparation and industrial quality control.

Our brand was established in 1988 and the quality system is certified to ISO 13485 with CE conformity on the instruments we ship internationally. As a China Laboratory Centrifuge Series Manufacturer and OEM/ODM production partner, we configure drive control, rotors, tube adapters and documentation around the working point a laboratory actually runs.

Our Centrifuge Range at a Glance

Seven current centrifuge platforms cover the routine spectrum of laboratory separation work. Each family is defined by format, control scheme and separation task rather than by a single fixed specification, so rotor and adapter selection is finalized with the order.

Where Centrifugation Fits in the Workflow

Centrifugal separation accelerates the settling of substances that differ in mass. In practice, that covers a defined set of preparative steps our customers run every day:

• Removing cellular elements from blood to obtain cell-free plasma or serum for analysis.
• Concentrating cellular elements and other biological fluid components for microscopic examination or chemical analysis.
• Eliminating chemically precipitated proteins from an analytical specimen.
• Separating protein-bound or antibody-bound ligand from free ligand in immunochemical and related assays.
• Resolving two liquid phases of different density, and extracting solutes from aqueous into organic solvents.
• Separating lipid components such as chylomicrons and lipoproteins from other plasma or serum fractions.

Sector demand shapes the configuration: life science and molecular biology laboratories work in micro-tubes and need refrigerated running, medical testing and diagnostic centres prioritise repeatable serum and plasma preparation, biotech and pharmaceutical groups need documented throughput, and food, environmental and industrial quality-control laboratories need dependable everyday separation. University and research institute teaching laboratories generally standardise on the mini and low-speed formats. Our Laboratory Instruments range covers the adjacent bench equipment these same workflows require.

Specifications We Confirm Before Production

Speed alone does not define a centrifuge. The proposal is built from the separation the sample needs, then translated into hardware:

Rotors, Adapters and Bench Integration

Rotor choice determines the tube formats a machine can accept and the acceleration profile the sample experiences. We select fixed-angle or swing-out geometry, matching adapters and the tube loading pattern with the application, and we confirm that the rotor's rated envelope covers the speed the protocol requires. Tube and tip supply is handled through our Laboratory Consumables range so that containers, adapters and instrument are dimensionally consistent.

• Control side: the mini platforms use a PI high-frequency, full-range wide-power-supply scheme that accepts AC100-240 V / 50-60 Hz; the 1-16N / 2-4B benchtop pair uses microcomputer control. Both are confirmed against the destination power environment.
• Bench side: footprint, lid clearance, ventilation space and the load-bearing surface are checked against the intended location before shipment.
• Operator side: balanced loading, tube rating limits and lid-closure behaviour are covered in the operating documentation supplied with each unit.
• Workflow side: for laboratories that record run parameters, programme storage, display format and timer resolution are fixed at configuration.

Where a protocol calls for a refrigerated run, the chamber is commissioned together with the rotor set. For example, the Qiujing Serene Series Benchtop Micro High-Speed Refrigerated Centrifuge 2-165LT is specified around the temperature setpoint and tube format the molecular biology workflow requires, not around a catalogue default.

Quality Control and Delivery Documentation

Manufacturing runs under a full-process quality system, from raw material inspection through in-process testing to finished-product inspection, supported by our in-house test laboratory. The company holds ISO 13485 certification and CE conformity, together with EU medical device notification, Class I medical device production record and export sales documentation for the applicable products.

Shipments travel in protective packaging suited to the rotor and instrument mass. Each unit is accompanied by its operating and maintenance documentation; where a customer requires acceptance records, configuration checklists or language-specific manuals, these are agreed during the quotation stage rather than assumed afterwards.

Maintenance, Spares and Support

Centrifuges reward simple discipline: rotors inspected for corrosion or scoring, adapters and tubes replaced when they deform, chambers and lids cleaned according to the sample type, and speed control checked against the protocol at planned intervals. Our maintenance guidance covers these routines for every platform.

• Spare rotors, adapters and commonly replaced parts can be quoted alongside the instrument so service intervals are planned in advance.
• Technical consultation, operation guidance and troubleshooting support continue after delivery for overseas partners.
• For multi-unit installations we coordinate rotor identification and labelling so a laboratory can track which rotor belongs to which protocol.

OEM/ODM Customisation and Project Inputs

Our engineering route runs through requirement consultation, solution and sample confirmation, precision manufacturing, then global delivery with after-sales support. Standard lead time is 10 working days, with minimum order quantity depending on model and customisation scope. OEM/ODM work covers specification adjustment, appearance and branding, and packaging solutions; samples can be supplied for performance verification before a bulk order is released.

Frequently Asked Questions

Which centrifuge models does Qiujing manufacture?

Seven platforms: Whirlwind Series Mini Centrifuge W40, W70 and W100; Cyclone Series Mini Centrifuge C70 and C120; Centrifuge L50; Serene Series Benchtop Low Speed Centrifuge 2-040NT; Serene Series Benchtop Micro High-Speed Refrigerated Centrifuge 2-165LT and 3-165LT; and the Benchtop High Speed / Low Speed Centrifuge 1-16N / 2-4B.

Can you supply a refrigerated centrifuge for plasmid extraction and protein work?

Yes. The 3-165LT is used for plasmid extraction and protein preparation, and the 2-165LT for molecular biology separations that need a controlled chamber temperature. Rotor and adapter configuration is fixed against your tube format and temperature setpoint.

Do the mini centrifuges run on both 110 V and 220 V supplies?

The Whirlwind Series uses a PI high-frequency, full-range, wide-power-supply control scheme rated for AC100-240 V / 50-60 Hz input, which suits laboratories in different power regions without a separate voltage variant. We still confirm the destination supply when the order is configured.

Can we order centrifuges under our own brand and packaging?

We operate OEM/ODM lines that cover specification adjustment, appearance and branding, and packaging solutions. Sample verification is available before bulk production, and the standard lead time after specification confirmation is 10 working days.

What information do you need to prepare a centrifuge quotation?

Send the sample type, tube format, required speed or RCF, run time, temperature requirement, batch size, power environment, control expectations and any branding or documentation requirements. With those inputs we return a configured model, rotor and adapter set, accessories and a delivery schedule.
