Pipetting Equipment Supplier

Shanghai Qiujing Biochemical Reagent & Instrument Co., Ltd. designs and manufactures precision liquid handling instruments in Shanghai. We operate as a China Pipetting Equipment Supplier across three working scales: manual and electric micropipettes, large-volume macropipettes and the X8 automatic micro liquid dispenser. These instruments are applied in assay set-up, sample preparation, reagent dispensing, serial dilution and quality-control testing in life science, medical testing, pharmaceutical, food, environmental and industrial laboratories.

The Qiujing brand has been dedicated to pipette research, development and production since 1988, with the Chinese and English trademarks registered in 1992. Our manufacturing is supported by CE and ISO 13485 certified quality management, an in-house test laboratory and a full-process inspection routine that covers raw material selection, in-process testing and finished-product testing.

Our Pipetting Range: Micropipettes, Macropipettes, Automated Dispensing

Range Match by Working Scale and Application

Micropipette: Micro-Volume Transfer and Plate Work

Air-displacement micropipettes are the working basis for most bench routines. Volume is set on the thumb wheel, the tip seals on the shaft, and the piston stroke draws and delivers the liquid. In our range this is offered as single-channel instruments for tube and vial work, and as 8-channel and 12-channel formats for microplate rows and columns where repeatability across channels matters more than speed of setting.

• Qiujing Lucky Series Single Channel Micropipette: ergonomic body, accurate and reliable handling for routine bench volumes.
• Qiujing Lotus Series Single Channel Fully Autoclavable Micropipette: revised internal structure with an ergonomic shape that reduces hand fatigue during long operating sessions.
• Qiujing Eco Series Micropipette Electric Pipettor: three working modes — pipetting, mixing and separating — with continuous separation of more than 3000 cycles and a digital display.
• Lucky Series 8-Channel and 12-Channel Micropipettes: multi-channel transfer for plate-oriented workflows requiring high efficiency and repeatability.
• Qiujing Airy Series Miniature Micropipette: compact format where bench space and short transfer distances are the constraint.
• Qiujing Sturdy Series Stepmate Stepper Pipette: continuous adjustable separation for repeated delivery from one filling step.

Macropipette: Large-Volume Transfer and Reagent Preparation

Where a micropipette becomes impractical, the macropipette range handles measured transfer from 0.25 mL to 5 mL and up to the 10 mL class. Typical tasks include preparing buffers and media, splitting culture volumes, adding bulk reagent to tubes or bottles, and transferring viscous or foaming solutions where a controlled delivery rate matters more than a very small volume increment.

• Qiujing E-flow Series Electric Large Capacity Pipette: motorised operation with adjustable separation speed for operators who repeat large-volume delivery through a shift.
• Qiujing H-Flow Series Manual Large Volume Pipettes: an economical and practical liquid controller for general preparation work.
• Qiujing Bustle Series Adjustable Quantitative Pipettor: adjustable dosage injector for workflows that combine several fixed delivery volumes.

Automatic Micro Liquid Dispenser X8

The X8 automatic micro liquid dispenser addresses the other end of the workflow: the same volume delivered again and again, without the operator resetting an instrument each time. It combines high efficiency, low operating noise and a safety-oriented design, which suits laboratories filling multiwell plates, dispensing into tube racks, or preparing dilution series where a single mis-set volume changes the whole batch.

Materials, Sterilisation and Handling Care

Contact parts, shaft sealing and tip fit determine how repeatable a pipette stays after months of use. Our autoclavable models are built for laboratories that sterilise between sessions rather than relying on chemical disinfection alone, and tip selection is treated as part of the pipetting configuration rather than an accessory decision.

• Fully autoclavable micropipette options for aseptic and cell-culture environments.
• Low-retention, racked and bagged pipette tips with a smooth inner wall, and tip specifications covering heat source, endotoxin, DNase and RNase control.
• Sealing and piston assemblies matched to the volume band so that small-volume channels are not pushed beyond their design range.
• Ergonomic body and reduced operating force on high-frequency models to limit hand fatigue during long sessions.

OEM/ODM Configuration, Integration and Delivery Support

We build pipetting ranges for laboratories, distributors and instrument brands, so configuration work is part of normal production rather than a special request. Our team takes the working volume band, channel format, sterilisation requirement and user interface preference, then proposes a model or a customised build.

• Requirement consultation: product parameters, application scenario, order volume and customisation requirement.
• Solution and sample confirmation: a targeted technical proposal, with samples for performance verification before specification sign-off.
• OEM/ODM scope: product design, specification adjustment, appearance customisation and packaging solutions, including branded supply for distribution programmes.
• Production and delivery: precision manufacturing under full-process quality control, standard lead time of 10 working days, safe packaging and global shipment.

Quality System, Documentation and Acceptance

Quality management at Qiujing is documented and certificate-backed. The company holds CE and ISO 13485 quality system certification, together with an EU Medical Device Notification certificate, a Certificate of Export Sales for Medical Devices and a Class I Medical Device Production Record Certificate. These documents support acceptance in regulated purchasing programmes and are issued with the commercial paperwork for confirmed orders.

On the production side, every instrument passes raw material inspection, in-process testing and finished-product inspection before packing. Tests are performed on our own test equipment, which also supports sample verification when a customer needs to confirm performance against an internal specification before a bulk release.

Information We Use to Configure Your Solution

Send the volume band, liquid description, format and target quantity and we will return a model recommendation, a customisation position and a delivery schedule. Where a specification cannot be fixed from the first set of data, we offer a sample for verification before the order is finalised.

Frequently Asked Questions

Which pipetting ranges does Qiujing manufacture?

We manufacture three ranges: micropipettes with single-channel, 8-channel and 12-channel formats; macropipettes for 0.25 mL to 5 mL and up to 10 mL liquid handling; and the X8 automatic micro liquid dispenser for repetitive micro-volume dispensing.

Which micropipettes can be autoclaved?

The Qiujing Lotus Series Single Channel Fully Autoclavable Micropipette and our fully autoclavable micropipette model are designed for sterilisation by autoclave. We confirm the sterilisation routine during configuration so that seals and internal parts match your cycle.
