Laboratory Balance Series Manufacturer

Shanghai Qiujing Biochemical Reagent & Instrument Co., Ltd. is a China-based Laboratory Balance Series manufacturer, producing benchtop electronic balances alongside our pipetting, mixing, centrifuge, bath and photometry ranges. The series is organised around weighing accuracy rather than cabinet size: 0.0001 g and 0.001 g for analytical work, 0.01 g and 0.1 g for preparation, formulation and control weighing.

Our balances are used in chemistry, biology and materials science laboratories, in university teaching, in food and environmental testing, and on industrial quality-control benches. Since the Qiujing brand was established in 1988 we have manufactured laboratory instruments in Shanghai, and the balance range is built on the same production and inspection sequence we apply across the instrument line.

Our Available Balance Range

Readability Bands and Where Each Fits

Critical Specifications We Confirm Before Production

Balance enquiries become a firm specification only when the working point is fixed. These are the parameters we lock down with you before a unit is scheduled:

• Capacity paired with readability, tested against both the heaviest container load and the lightest sample weighed in routine work.
• Repeatability and linearity expectations stated at the actual working point, not only at full capacity.
• Stabilisation time and display update behaviour where throughput per shift is a constraint.
• Pan dimensions and weighing chamber clearance for the largest flask, beaker or sample boat used.
• Calibration approach: external weight class, routine check interval and the interval your quality system records.
• Units and weighing modes the method genuinely calls for.
• Destination power supply, plug type and the language required on labels and documentation.

Configuration, Data Output and Workflow Integration

Some benches need nothing more than a stable four-decimal display. Others need the weight to arrive in a batch record, a worksheet or a LIMS entry, and that is a configuration decision we settle early rather than after delivery. We ask where the reading goes, who transcribes it, and how often.

• Whether results are read on screen, printed, or passed to a downstream system, and which interface the receiving system expects.
• Cable routing, bench cut-outs and how the balance sits relative to the PC or terminal.
• Trigger method for printing or capture, so operators are not removing hands from the sample container.
• Whether the unit is installed inside a fume hood, a weighing room or a mobile bench.

Where a balance sits in a wider bench workflow, we coordinate it with the rest of our Laboratory Instruments range — magnetic stirrers, mixers, water baths and centrifuges — so power, footprint and sample flow are planned together rather than item by item.

Installation Conditions and Operating Discipline

A balance only holds its class when the site supports it. High-resolution weighing is sensitive to air movement, vibration and thermal drift, so installation is part of the specification.

• Rigid, low-vibration bench; not on a shared bench with a centrifuge, vacuum pump or compressor.
• Position away from doors, windows, direct sunlight and air-conditioning outlets.
• Levelling checked with the integral level indicator every time the unit is moved.
• Warm-up period allowed before calibration-sensitive work begins.
• Stable mains supply; shared laboratory circuits benefit from local suppression.
• Chamber and draft shield handled calmly, with anti-static measures for powders and plastic vessels.
• Cleaning routine and a stored check weight kept with the instrument.

Quality Control and Acceptance

Every balance passes incoming raw-material inspection, in-process testing and finished-product inspection before packing, supported by our in-house test laboratory at the 24,000 m² Shanghai production base. Our quality management system holds CE and ISO 13485 certification, and our technical team maintains patents supporting the instrument line.

Sample units are available for performance verification before a bulk order. Specifications are finalised after your confirmation and before formal production begins; standard lead time is 10 working days, adjusted for quantity and customisation scope.

OEM/ODM, Documentation, Packaging and Support

• OEM/ODM: product design, specification adjustment, appearance and packaging customisation based on your drawings or samples.
• Documentation and training: operation guidance and technical consultation for laboratory staff, in the language agreed for the project.
• Packaging and delivery: packing arranged for the sensitivity of the instrument and the shipping mode, prepared for global shipment.
• After-sales: product consultation, operation guidance and troubleshooting support for overseas partners.

Information We Use to Configure Your Solution

Frequently Asked Questions

Which readability should we specify for our laboratory?

Start from the lightest sample weighed in routine work. The Qiujing Precise Series Balance 0.0001 g / 0.001 g covers analytical and standard weighing, while the Qiujing Basic Series Balance 0.1 g / 0.01 g / 0.001 g and the Qiujing Accura Series Balance 0.1 g / 0.01 g / 0.001 g handle preparation, formulation and control weighing. Give us the sample type and range and we will confirm the class and capacity.

Do you build balances under our own brand?

Yes. We provide OEM/ODM service covering product design, specification adjustment, appearance and packaging, working from your drawings or samples, and we finalise the specification with you before production starts.

Can we verify a sample before committing to a bulk order?

We supply samples for performance verification. You check the unit against your own weighing routine and environment, and only then do we lock the production specification.

What is the typical lead time and delivery scope?

Standard lead time is 10 working days, adjusted where quantity or customisation changes the build. Instruments are packed according to their sensitivity and shipped to overseas destinations with the documentation agreed for the order.

How is accuracy maintained after delivery?

Each unit leaves after raw-material, in-process and finished-product inspection under our CE and ISO 13485 certified quality system. After delivery, our technical team supports calibration practice, operating questions and troubleshooting for as long as the instrument is in service.
