Laboratory Instruments Supplier

Precision Laboratory Instruments Manufactured in Shanghai

Shanghai Qiujing Biochemical Reagent & Instrument Co., Ltd. develops and manufactures precision laboratory instruments for chemistry, biology, environmental, clinical and industrial laboratories. Our brand has been active in the laboratory instrument sector since 1988, and the range now covers 44 instruments across eleven instrument families, supported by pipetting products and laboratory consumables.

We work both as a catalogue supplier and as an OEM/ODM partner, so our position is a China Laboratory Instruments Supplier that can ship a defined model or build to a customer specification. Each family is therefore engineered around a working point rather than a single fixed configuration.

Our Laboratory Instruments Range

The table below shows how the eleven instrument families in this range map onto routine laboratory work. Models, control types and vessel formats are confirmed at quotation stage.

Application Fit Across Laboratory Types

Instrument selection follows the sample and the result that has to be produced, not the bench it stands on. These are the environments our range is configured for most often.

• Industrial R&D and quality control: product development, performance testing and incoming inspection in electronics, new materials, chemicals and manufacturing.
• Food and environmental testing: sample pre-treatment, component detection and data analysis for food safety, environmental monitoring and contract analysis.
• Universities and research institutes: teaching experiments and research across chemistry, biology, medicine and materials science.
• Life science research: molecular biology, cell research and microbial analysis, including plasmid extraction and protein work.
• Medical testing: clinical testing, disease screening and sample processing where repeatability matters.
• Biotechnology and pharmaceuticals: drug development, sample preparation and production-process monitoring with stricter accuracy and repeatability demands.

Critical Specifications Behind Each Model

Separation: centrifuges and rotor selection

Centrifuge configuration is set by tube format, working volume and the separation result rather than by headline speed alone. Our mini centrifuge family uses a PI high-frequency, full-range control scheme running on AC100–240V / 50–60Hz input, which keeps the same unit usable on different mains supplies. The Serene benchtop micro high-speed refrigerated models are applied in molecular biology, plasmid extraction and protein preparation, while the benchtop 2-4B low-speed unit works at 4000 rpm under microcomputer control for routine separations.

Stirring, mixing and temperature control

For magnetic stirring we confirm stirring volume, viscosity and whether heating is required. The Top Magic TOP1/TOP1H single-channel and TOP4/TOP4H four-channel units carry LCD displays with adjustable speed and time, and the TOP380 and Mini Star models use DC brushless motors. Liquid-volume mixing is covered by the mixer range, where a vortex unit can bring 40 ml of liquid into full rotation in about five seconds. The electric cantilever mixers add six-segment program control for dispersion and dissolving work.

Measurement: balances, pH meters and photometers

We match readability and repeatability to the smallest quantity the method actually weighs or reads, then align electrode type, wavelength requirements and sample handling with the client's procedure. The photometer and pH meter families are specified together with the reference standards and calibration routine the laboratory already uses, so the instrument slots into an existing workflow.

Configuration, Controls and OEM/ODM Customization

Standard models already cover heated and unheated operation, single and multi-position stirring, and mini or benchtop footprints. Where a standard model does not fit, we run the requirement through our development process.

• Product design and specification adjustment against drawings or submitted samples.
• Appearance, branding and packaging customization for distributor and private-label programmes.
• Control-parameter programming for speed, time and temperature profiles.
• Sample units built for performance and compatibility verification before the full order.

Quality Control, Documentation and Acceptance

Our quality management system is certified to ISO 13485 and we hold CE certification for the instrument range. Production is controlled at three checkpoints — incoming raw material inspection, in-process testing and finished-product inspection — supported by an in-house test laboratory, so accuracy and stability are verified on the unit that is shipped, not only on a reference sample. Our certification documentation includes EU Medical Device Notification certificates, a Class I Medical Device Production Record Certificate and a Certificate of Export Sales for Medical Devices.

Acceptance is usually confirmed on sample performance for the specific application, with the agreed specification recorded on the order before production begins. This keeps the delivered configuration identical to the approved sample.

Installation, Utilities, Safety and Serviceability

• Benchtop units are placed on a level, vibration-free surface; balances and centrifuges are particularly sensitive to nearby vibration and air movement.
• The mini centrifuge control scheme accepts AC100–240V / 50–60Hz, which simplifies deployment across different regions.
• Refrigerated centrifuges need clearance for heat rejection, and heated stirrers, water baths and metal baths need their hot surfaces treated as part of normal lab practice.
• After-sales support covers product consultation, operation guidance and troubleshooting for the operating life of the equipment.

Frequently Asked Questions

Which laboratory instruments does Qiujing manufacture?

We manufacture eleven instrument families: centrifuges, magnetic stirrers, laboratory mixers, electric cantilever mixers, water baths, metal baths, balances, photometers, pH meters, preparation instruments and analytical instruments, together with micropipettes, macropipettes, an automatic micro liquid dispenser and laboratory consumables.

Do you provide OEM/ODM customization?

Yes. We adjust specifications against customer drawings or samples, and we also handle appearance and packaging customization, including private-label programmes for distributors. A sample is confirmed before series production so the delivered units match the approved configuration.

Which certifications support the instrument range?

Our quality management system is certified to ISO 13485 and the range carries CE certification. Our documentation set also includes EU Medical Device Notification certificates, a Class I Medical Device Production Record Certificate and a Certificate of Export Sales for Medical Devices.

Can you supply samples before a bulk order?

Yes. We provide samples so the performance, dimensions and compatibility of the selected model can be verified against your application before the order is placed in production.

What lead time do you quote?

Standard lead time is 10 working days. It extends for customized specifications, larger quantities or multi-family orders, and we confirm the schedule with the order details.

Can instruments, pipettes and consumables be ordered together?

Yes. Laboratory instruments, pipetting products and laboratory consumables are supplied through the same channel, so a laboratory setup can be consolidated into one order with one delivery schedule.
