Laboratory Micropipette Manufacturer

Precision Micropipettes Manufactured in Shanghai

Shanghai Qiujing Biochemical Reagent & Instrument Co., Ltd. is a China-based Laboratory Micropipette Manufacturer located in Songjiang District, Shanghai. We research, develop and produce precision micropipettes for research institutes, clinical testing laboratories, biopharmaceutical quality control, food and environmental testing, industrial R&D and teaching laboratories, supplying them as standard models or as OEM/ODM configurations built to a customer specification.

Our brand dates to 1988, with Chinese and English trademarks registered in 1992. In-house production, assembly and testing technology supports a pipette range covering 0.1 µL to 10 mL, together with the quality system work behind CE and ISO 13485 certification and a number of technical patents.

• Single-channel variable-volume micropipettes in ergonomic and fully autoclavable bodies
• 8-channel and 12-channel multichannel micropipettes for plate-format work
• Electronic pipettor with pipetting, mixing and separating modes
• Miniature and repeating stepper formats for confined benches and serial aliquoting

Our Micropipette Range

Each family below is an air-displacement micropipette with a disposable tip, a volume-setting mechanism and a plunger stroke matched to the model's working volume. Selection normally follows the liquid handled, the number of samples processed per session and the sterilization route used in the laboratory.

Where volumes above the micropipette range or automated plate dispensing are required, the same platform continues through our Macropipette range and the Automatic Micro Liquid Dispenser, which sit alongside the micropipettes in our pipetting family.

Channel Format and Configuration Logic

Working volume and samples per session decide the format before anything else. We confirm the working point and the plate or tube format first, then match a single-channel, multichannel, electronic or stepper body to the protocol instead of adapting a protocol to the pipette afterwards.

Single-channel manual

Lucky and Lotus single-channel models handle one sample at a time with a variable volume setting, which suits method development, reagent preparation and teaching routines. Lotus and the fully autoclavable model are built for steam sterilization, while the standard body prioritizes light plunger force for long bench sessions.

Multichannel 8 and 12

• 8-channel bodies transfer eight tips at once for 96-well plate filling and plate assays
• 12-channel bodies cover a full plate row where row-by-row repetition would slow throughput
• Tip spacing, tip cone fit and ejection force are matched to the plate and tip you specify

Electronic and repeating formats

The Qiujing Eco Series electric pipettor runs pipetting, mixing and separating modes with a digital display, supporting more than 3,000 continuous dispensing steps for long aliquoting sequences. The Sturdy Series Stepmate stepper pipette delivers continuous adjustable steps when one volume must be repeated across many receptacles.

Where the Range Fits

Micropipettes carry high-precision liquid handling across the laboratory workflows our customers run daily. The format and volume range are chosen against the liquid and the number of transfers, not against a single preferred model.

• Life science research: molecular biology, cell culture and protein work, where sterile tips and autoclavable bodies matter
• Medical and clinical testing: sample processing and assay preparation, where repeatability between operators is critical
• Biotechnology and pharmaceutical QC: drug development, sample preparation and in-process checks with documented verification
• Food and environmental testing: sample pretreatment and component detection across many small volumes
• Industrial R&D and quality control: electronics, new materials and chemicals testing with precise data collection
• Universities and institutes: teaching benches and research groups needing durable, low-maintenance instruments

Materials, Autoclavability and Tip Compatibility

Air-displacement micropipettes draw liquid through a disposable tip, so tip cone geometry, seal condition and plunger feel determine how consistently a volume is delivered. Our autoclavable models are built for repeated steam cycles without losing setting stability.

• Fully autoclavable bodies for laboratories that sterilize instruments between batches
• Ergonomic body geometry and controlled plunger force for high-frequency operation
• Matched tips with smooth inner walls, low retention and no heat source, endotoxin, DNase or RNase
• Bagged and racked tip formats supplied through our laboratory consumables line
• Foam-forming, high-vapour-pressure and high-viscosity liquids need tip and technique matched during configuration

Accuracy, Repeatability and Quality Control

Every unit passes through the same staged controls from incoming components to packed product. Our in-house test laboratory checks volume delivery at the relevant working point, and records are kept inside the ISO 13485 quality system.

OEM/ODM Customization

We support distributors and laboratory brands with OEM and ODM work based on drawings, samples or a defined specification. Customization runs through requirement consultation, solution and sample confirmation, precision manufacturing, then global delivery with after-sales support.

• Product design adjustments and specification changes for a specific volume range or application
• Appearance customization, including body colour and printed branding
• Packaging solutions matched to your market, with retail or bulk configurations
• Sample units for performance verification before formal production

Information We Use to Configure Your Solution

A proposal is prepared from the working point, the liquid and the production target rather than from a catalogue number alone. The table shows the inputs our sales and technical team work from when specifying a micropipette order.

Delivery, Operation Guidance and Maintenance

Pipettes are packed for safe transport and shipped internationally, with documentation prepared for the order. After delivery our technical team supports product consultation, operation guidance and troubleshooting for overseas partners.

• Routine care covers cleaning of the outer body, inspection of the tip cone and checking the seal for wear
• Autoclavable models follow the sterilization cycle agreed during configuration
• Field complaints and application questions are handled through our sales and technical contact, including spare component supply where applicable
• Operator training materials and usage guidance are provided for multi-operator laboratories

Frequently Asked Questions

What volume range do your micropipettes cover?

The micropipette range spans a minimum of 0.1 µL to a maximum of 10 mL across single-channel, multichannel, electronic, miniature and stepper formats.

Which model should be used for 96-well plate work?

The Lucky Series 8-channel and 12-channel micropipettes are the plate-format choices; we confirm tip spacing and the plate you use so ejection and sealing stay consistent.

Are your micropipettes autoclavable?

The Lotus Series and the fully autoclavable model are built for steam sterilization. For other bodies, we confirm the sterilization route during configuration so the correct model is supplied.

Do you provide OEM/ODM micropipette manufacturing?

Yes. We work from drawings, samples or a written specification and cover product design, specification adjustment, appearance customization and packaging solutions, with samples supplied for verification before production.

What certifications support your quality system?

Our quality management system holds CE and ISO 13485 certification, and the company has secured a number of technical patents supporting micropipette production and testing.

What is the standard lead time and delivery scope?

Standard models normally ship on a lead time of about 10 working days after order details are confirmed. Orders are packed for safe transport and shipped internationally, with operation guidance and troubleshooting support provided after delivery.
