Automatic Micro Liquid Dispenser Manufacturer

Our Position in Automatic Micro Liquid Dispensing

Automatic dispensing is the part of our liquid-handling family that delivers measured micro-volumes repeatedly from a stored supply instead of drawing each aliquot by hand. The model listed in this category is the Qiujing X8 automatic micro liquid dispenser, engineered around high efficiency, low operating noise and safe handling for routine bench work.

Each unit is treated as a complete liquid path rather than a single instrument, so the configuration decision covers the reservoir, the delivery head, the nozzle and the consumables that touch the reagent.

• Reservoir format: bottle-top mounting, or a separate reservoir feeding the dispensing head, selected against the reagent container and bench layout.
• Dispensing pattern: single aliquots, repeated equal aliquots across a long series, or continuous delivery.
• Triggering: manual push-button control for short runs and hands-free triggering for serial work.
• Wetted path: materials chosen against the reagent chemistry, cleaning agent and sterilisation routine.
• Consumables: tips and tubing matched to the nozzle so every liquid contact point is defined.

Where Automatic Dispensing Fits in the Workflow

Dispensers take over the bench tasks that repeat the same volume dozens or hundreds of times: filling microplate wells, adding buffer or media to sample tubes, preparing serial dilutions, distributing standards and controls, and aliquoting reagent before analysis. Configurations in this family span working volumes from roughly 0.2 µL up to 100 mL depending on the model, nozzle and reservoir, so one platform concept can serve a molecular biology bench and a millilitre-scale reagent station.

The applications we configure for most often are drawn from the sectors our instruments already serve:

• Industrial R&D and quality control: repeated reagent addition for performance testing and incoming inspection.
• Food and environmental testing: sample pretreatment, spiking and aliquot preparation across batches.
• Life science research: plate filling, dilution series and reagent distribution for molecular and cell work.
• Medical testing and biotechnology: standards, controls and sample aliquots where the same volume is repeated all day.
• Universities and institutes: teaching benches and shared equipment rooms where a simple, quiet unit is preferred.

Liquid-Handling Range We Supply

The dispenser does not stand alone in a laboratory. Our pipetting range and supporting instruments cover the transfers before and after the dispensing step, so a bench can be equipped from one supplier with matched consumables.

Where a project needs single transfers at microlitre scale alongside the dispenser, our micropipettes are specified with matching tips so the whole bench follows one consumable standard.

Configuration Choices Built Into Each Unit

Configuration starts from the working point, not from a catalogue number. We fix the following variables with you and record them in the order specification.

• Volume range and nozzle: the smallest and largest aliquot define the delivery head and nozzle bore.
• Dispensing mode: single shot, repeated equal aliquots, or continuous flow, with the corresponding control option.
• Wetted materials: tubing, seals and head materials selected for aqueous buffers, acids, solvents or detergents.
• Autoclavable parts: removable components are confirmed for the sterilisation routine you run, including cycle count expectations.
• Electrical configuration: the unit is supplied for the destination power standard and plug type.
• OEM/ODM scope: branding, colour, labelling, manual and packaging arranged around your market requirements.

Critical Specifications Confirmed Before Quotation

The parameters below decide the unit we propose and the verification method applied before dispatch. Values are confirmed per model and per working point rather than assumed from a general data sheet.

Controls, Bench Integration and Operator Safety

Each dispenser is a bench instrument: it needs a level surface, a stable power point of the correct standard, and clearance for the reservoir and tubing run. Where the dispenser feeds a wider workflow, we confirm the interface before the order is released so that triggering, cycle time and mounting match the surrounding equipment.

• Triggering options: push-button, hands-free or remote trigger, depending on how the operator handles tubes or plates.
• Mounting: freestanding bench placement or bracket-mounted positioning beside the reservoir.
• Operator safety: routing that avoids splash, over-pressure in closed containers and accidental contact with the nozzle.
• Noise: low operating noise is a stated design objective of the X8, which matters in shared rooms and open laboratories.
• Priming and purging: the sequence is defined in the manual and repeated at start-up and before reagent changes.

Materials, Cleaning and Serviceability

Wetted components are selected for the reagent and for the cleaning routine that follows it. Removable parts intended for autoclaving are confirmed at configuration stage, and the cleaning procedure is documented so that accuracy is restored after every reagent change rather than degrading quietly.

• Routine cleaning: flushing and rinsing sequences for aqueous and solvent-based reagents.
• Wear parts: nozzles, seals and tubing are supplied as replaceable items to keep units in service.
• Consumables: tips matched to the nozzle maintain a consistent liquid contact surface.
• Service: technical consultation covers operation guidance and troubleshooting for units in the field.

Quality Control, Documentation and Acceptance

Production runs under full-process control: raw material inspection, in-process testing and finished-product inspection are applied before an instrument is released. The company holds CE certification and an ISO 13485 quality management system, with medical device notification, export sales and Class I production record certificates maintained for the applicable product lines.

Acceptance follows a defined path for instrument projects:

1. Sample confirmation against the agreed specification before bulk production.
2. Functional checks and volume verification at the working point.
3. Final inspection of assembled units, accessories and consumables.
4. Documentation pack with the shipment, covering operation and maintenance instructions.

• Batch size and required aliquots per hour.
• Reservoir format and available bench footprint.
• Contacts, other equipment and possible automation tie-in.
• Destination country, power standard and plug type.
• Cleaning, autoclave and contamination-control routine.
• OEM/ODM scope, branding, packaging and documentation language.
• Order quantity, delivery schedule and sample requirements.

Frequently Asked Questions

What does Qiujing manufacture in this category?

We manufacture the automatic micro liquid dispenser line, currently led by the Qiujing X8 model, together with micropipettes, macropipettes and the consumables used with them. Production, assembly and testing take place in our own facility in Shanghai, and the range is supplied under CE certification and an ISO 13485 quality management system with OEM/ODM options.

Can the dispenser be configured for a specific reagent and volume?

Yes. We review the volume range, liquid properties, chemical compatibility and throughput target, then confirm the delivery head, nozzle, tubing, wetted materials and control type. If the reagent is unusual, sample testing is arranged before the configuration is frozen.

Do you support OEM/ODM customization?
