Analytical Instruments Series Manufacturer

Shanghai Qiujing Biochemical Reagent & Instrument Co., Ltd. manufactures and supplies analytical instruments for laboratories that make decisions from measured data — immunoassay reading, cell counting, conductivity and related bench measurement — together with the pipetting and sample-handling equipment used in the same workflows. Our brand was established in 1988, and our quality management system holds CE and ISO 13485 certification.

A China Analytical Instruments Series Manufacturer in Shanghai

We are an Analytical Instruments Series Manufacturer, building this family at our Shanghai site for laboratories, environmental testing bodies, industrial quality-control departments and medical testing laboratories. The series sits inside our wider Laboratory Instruments programme, which also covers centrifuges, magnetic stirrers, water baths, balances, photometers and pH meters, so a complete bench can be equipped from one production source.

Analytical instruments are grouped by the setting they serve rather than by one principle of measurement: laboratory experiments and research, environmental pollution monitoring, process and on-site measurement, maintenance and working-environment checks, medical examination, automation and information-processing systems, and bio-related analysis. Configuration work here starts with that setting — the sample, the matrix, the operator and the decision the reading has to support.

The Analytical Instruments Series Range

Three instruments carry the series today, each matched to a different measurement job rather than to a single industry.

Application Fit Across Laboratory, Environmental and Industrial Work

The table below maps our current analytical range and the complementary measurement instruments we build to the workflows they serve. Where a project needs both measurement and sample preparation, we configure the bench as one package.

Reading conductivity on site and reading an immunoassay plate in a food testing laboratory are different jobs, and we keep the configuration work separate: field instruments prioritise display readability, internal storage and printing, while plate-based instruments prioritise assay protocol, temperature stability and result handling.

Critical Specifications and Configuration Choices

• Measurement parameter and working range — matched to expected sample values and the resolution your method requires.
• Sample format and volume — plate-based immunoassay, cell suspension, or liquid sample for conductivity and pH.
• Temperature behaviour — the P902 applies automatic temperature compensation; ELISA reading and cell counting depend on stable ambient and sample temperature.
• Data handling — touch-screen or LED display, built-in mass storage, wireless Bluetooth printing, or output into your laboratory records.
• Calibration and reference materials — standard and buffer solutions, calibration intervals and check procedures.
• Utilities and bench layout — stable supply, level surface, clearance from vibration and heat sources.

Sample Preparation and Supporting Instruments

Analytical results depend on what happens upstream. Our Micropipette range, macropipettes and automatic micro liquid dispenser cover the volume steps that feed an ELISA plate, a cell suspension or a conductivity sample, and our pipette tips are produced without heat sources, bagged, racked and low retention to keep transferred volumes consistent.

Complementary measurement instruments complete the same bench. The Laboratory pH Meter Series covers buffer and sample pH checks alongside conductivity, while our photometer series handles routine colorimetric measurement for laboratories that need both absorbance and immunoassay capability.

Quality Control, Documentation and Acceptance

Raw-material inspection, in-process testing and finished-product inspection run through production, so each instrument is checked against the same performance points before it is packed. Our quality management system is certified to ISO 13485 and our instruments carry CE marking; sample units can be supplied so your laboratory verifies performance and compatibility before a bulk order is released.

• Operating instructions and shipment documentation for the delivered configuration.
• Sample units for performance and compatibility verification.
• Technical consultation, operation guidance and troubleshooting support after delivery.

Installation, Utilities, Operator Safety and Maintenance

All three instruments are bench-top units. We confirm supply voltage, bench space and ambient conditions before shipment, and the installation notes that travel with the instrument cover levelling, connection and first-run checks.

• Power — stable single-phase supply at the voltage confirmed for your destination.
• Environment — level bench, away from vibration, direct heat and strong draughts.
• Electrodes and sensors — rinse and store as instructed; replace on the interval set by your calibration records.
• Cells and optics — keep clean and dry, using only the cleaning agents named in the instructions.
• Operator safety — follow the shipped instructions for reagent handling and dispose of assay waste under local laboratory rules.

OEM/ODM Customization, Packaging and Delivery

OEM/ODM work is part of the series: product design changes, specification adjustment, appearance customization and packaging solutions are handled from your drawings or samples, with the specification frozen after sample confirmation. Standard production lead time is 10 working days, and the delivery schedule for a specific order is fixed once model, quantity and customization scope are settled. Instruments are packed for export shipment and dispatched to overseas destinations.

Information We Use to Configure Your Solution

A proposal is built from the working point, not from a catalogue number alone. These are the inputs that let us fix the model, the options and the acceptance checkpoints.

With the application, sample details and target quantities in hand, our technical team returns a configured specification, a sample arrangement and a delivery plan for the confirmed instruments.

Questions From Project and Procurement Teams

Which analytical instruments do you supply today?

The Analytical Instruments Series covers the QJ-MR-60 touch-screen enzyme-linked immunosorbent assay analyzer for food safety testing and environmental monitoring, the QJ-cell automatic cell counter for split cell counting, and the P902 conductivity measuring instrument with automatic temperature compensation and wireless Bluetooth printing. Backing equipment from our pipetting, centrifuge, mixer, balance, photometer and pH meter ranges comes from the same production site.

How is the ELISA analyzer matched to a specific assay?

We work from the assay you run — the detection arrangement, the plate workflow and the way results are recorded — and confirm those points before the order is released. Where a requirement falls outside the standard configuration, it is handled through our OEM/ODM process rather than by adapting the instrument after arrival.

What does the P902 offer for field and on-site conductivity work?

The P902 uses an LED display with built-in mass storage and wireless Bluetooth printing, and applies automatic temperature compensation so conductivity readings track changes in sample temperature. That combination suits environmental monitoring, water quality checks and process measurement where results are recorded away from the bench.

Can we receive sample units before a bulk order?

Yes. Samples are provided for performance and compatibility verification, and the specification is finalised after your confirmation. Volume pricing, minimum order quantity and delivery are then set against the confirmed configuration.

How is quality controlled, and what travels with the instruments?

Production follows raw-material inspection, in-process testing and finished-product inspection under a quality management system certified to ISO 13485, with CE marking on our instruments. The shipment carries the operating instructions and documentation for the delivered configuration, and our team supports operation guidance and troubleshooting after installation.

What supporting equipment can be supplied in the same order?

Pipettes, macropipettes, the automatic micro liquid dispenser, pipette tips, centrifuges, mixers, water baths, balances, photometers and pH meters can be grouped into one shipment, so a laboratory receives a matched bench instead of assembling it from separate purchases.
