Shanghai Qiujing Biochemical Reagent & Instrument Co., Ltd. builds the benchtop hardware that carries a sample from raw material to a measured result. Our brand was established in 1988, and Qiujing has developed precision micropipettes, mixers, centrifuges, baths and preparation instruments for laboratories working in industrial R&D and quality control, food and environmental testing, life science research, medical testing and biopharmaceutical production.
Sample preparation converts an as-received specimen into a state an analytical method can accept: digestion, homogenization, grinding, filtration, drying and temperature-controlled incubation. Our preparation range covers the thermal, agitation and separation side of that workflow. We supply it as a China laboratory preparation instruments manufacturer with OEM/ODM engineering, CE and ISO 13485 quality systems, and an established export business serving overseas laboratory distributors and end users.
The current Laboratory preparation instruments manufacturer family is anchored by the Qiujing YKJ-16 intelligent digester, a benchtop unit with a colour LCD interface, adjustable temperature and time parameters and thermal insulation built for a stable hold step. Around it, we supply the companion equipment that a preparation bench needs, so a single order can equip a complete workflow rather than a single station.
| Product family | Role in sample preparation | Main selection variables |
|---|---|---|
| YKJ-16 intelligent digester | Temperature- and time-controlled digestion of solid and semi-solid samples | Programme steps, vessel format, hold stability, fume handling |
| Water baths | Reagent warming, thawing, water-bath incubation | Bath volume, temperature range, uniformity, lid and rack type |
| Metal baths | Dry-block digestion and incubation of small tubes | Block format, well count, tube diameter, heating rate |
| Vortex, magnetic stirrer and electric mixer series | Resuspension, homogenization, dissolution of powders and viscous samples | Speed range, orbit or stirrer diameter, sample volume, viscosity, gasket wear |
| Laboratory Centrifuge Series | Clarification, phase separation, cell and precipitate recovery | Rotor and bucket type, relative centrifugal force, tube format, run time |
| Micropipettes, macropipettes, automatic micro liquid dispenser | Reagent addition, aliquotting, serial dilution before analysis | Volume range, single or multichannel, accuracy and repeatability, autoclavability |
| Balances, pH meters, photometers | Gravimetric preparation and verification of prepared solutions | Readability, capacity, measuring range, resolution, calibration routine |
| Pipette tips and consumables | Contamination-controlled transfer of samples and reagents | Filtered or unfiltered, racked or bagged, low retention, nuclease-free status |
The Qiujing YKJ-16 is built around the two parameters that decide digestion reproducibility: temperature and time. Both are set on the colour LCD interface, so a validated programme can be repeated by different operators without manual intervention. Insulation around the working zone holds the set point through the digestion step instead of letting the block cool while vessels are being loaded.
We configure the unit around the digestion chemistry that will actually be run. Acid digestion of food, feed or environmental solids, ambient-pressure wet digestion before spectrometric measurement and temperature-controlled extraction each place different demands on vessel selection, loading pattern and programme length. Share the digest volume, acid or solvent system and the target hold time, and we will match the instrument configuration and vessel set to the method. Full model data is listed on the Qiujing YKJ-16 intelligent digester specification sheet.
Preparation bench pairing: a digester is usually ordered together with a Laboratory Water Baths Series unit for cooling and post-digestion temperature steps, a centrifuge for clarification, and pipetting equipment for volumetric make-up. We quote these as one configuration when the workflow is known.
Preparation equipment is used differently in each environment we serve, and the delivered configuration follows that difference.
Digestion and bath performance is governed by a small set of variables. We confirm these against the method rather than against a catalogue number alone.
Preparation instruments are bench units, so integration work is mostly electrical and environmental. We size the power configuration to the destination market, and our benchtop equipment is engineered around wide-range switching supply designs — the Qiujing Whirlwind mini centrifuge series, for example, runs from AC100–240 V / 50–60 Hz input, and we apply the same approach to preparation hardware where the market requires it.
Installation planning covers bench footprint and clearances, ventilation for acid digestion work, fume-extraction expectations at the customer site, and a stable level surface for units with moving vessels. Operator-facing controls are kept simple: parameter entry on the LCD, an unambiguous run state, and physical separation between the hot working zone and the operator's hands. We supply operating and safety instructions with each unit, and our technical team covers operation guidance and troubleshooting during after-sales support.
Qiujing works under a documented quality management system with CE and ISO 13485 certification, and holds EU medical device notification, medical device export sales and Class I medical device production record certificates. Our in-house test laboratory supports development and finished-product verification, and we hold technical patents covering product design work.
Production is controlled at three checkpoints — incoming raw material inspection, in-process testing and finished-product inspection — with the results recorded against the order. For preparation instruments, acceptance at the customer site normally covers visual inspection and packing integrity, an insulation and earth-continuity check, a no-load run to confirm control response, and a repeatability run on the agreed set point using the customer's own vessels. We supply the documentation set needed for that acceptance before shipment.
A preparation instrument proposal is only as good as the process detail behind it. We use the following project inputs to build the configuration, the bill of auxiliary items and the quotation.
We run OEM/ODM projects from requirement consultation through solution and sample confirmation, precision manufacturing and global delivery, with after-sales support covering product consultation, operation guidance and troubleshooting. Customisation covers product design, specification adjustment, appearance and packaging — relevant to distributors building a local brand and to end users needing a bench that matches an existing method.
Standard production lead time is 10 working days; the schedule for a configured or customised unit is confirmed once the specification is frozen. Units ship with operating instructions and the agreed test records, packed for international transport, and spare parts and consumable accessories are quoted with the instrument so that the bench stays serviceable after commissioning.
We manufacture and supply the intelligent YKJ-16 digester together with the companion equipment a preparation bench needs: water baths, metal baths, vortex and magnetic mixers, electric mixers, centrifuges, balances, pH meters, photometers and the pipetting and consumable items used before and after the thermal step.
Yes. Send the sample matrix, acid or solvent system, vessel format, target temperature and hold time, and we will confirm the programme structure and vessel set. Where a method uses several temperature stages, the programme is segmented accordingly and the customer's own vessel geometry is taken into account when configuring the working zone.
We do. OEM/ODM scope includes specification adjustment, appearance and enclosure customisation, branding and packaging design, supported by our R&D team. Projects start from drawings, samples or a written functional requirement, and we confirm the specification on a sample before formal production.
Orders are produced under our CE and ISO 13485 certified quality system with incoming material inspection, in-process testing and finished-product inspection recorded against the build. Certificates covering EU medical device notification, medical device export sales and Class I medical device production records are held by the company, and the relevant test documentation accompanies the shipment.
Samples are available for performance and compatibility verification before bulk orders. Standard production lead time is 10 working days; configured or customised units are scheduled after specification confirmation, and the delivery window for a specific model, quantity and destination is stated in the quotation.
The preparation method and sample matrix, expected daily throughput, vessel format, supply voltage for the destination market, any OEM/ODM requirements and the documentation or training scope needed. With those inputs we return a configuration covering main unit, auxiliary bench equipment, consumables and spare parts in a single proposal.
