Product Description,Dual Bulb Pipette,Exact Volume Transfer Pipettes.

If you are sourcing an Exact Volume Transfer Pipette for a self-test kit line, a POC diagnostic assembly, or a clinical/molecular biology lab, the decision usually comes down to three things: dispensing consistency batch after batch, material compliance you can document for your own customers, and a supplier who can hold your tooling and specs long-term rather than a one-off trade order. That is the sourcing logic this page is built around.

ApsNesswell manufactures this Exact Volume Transfer Pipette  as a single-piece, disposable liquid transfer tool. Squeeze the upper bulb to draw liquid up the stem, squeeze again to dispense: no calibration, no graduation reading, no separate pipette tip. It removes the training step that a conventional micropipette requires, which is exactly why it is the standard liquid-transfer component built into most rapid antigen, fertility, and home-testing kits worldwide.

Feature,Plastic Pasteur Pipette,Dual Bulb Pipette.
Pasteur pipettes, available in both plastic and glass materials, serve as a staple in laboratories for transferring small volumes of liquids with precision. These slender, tapered tools are named after the famous Scientist Louis Pasteur and are indispensable for tasks requiring careful manipulation of liquid samples.
Plastic pasteur pipettes offer the advantage of being disposable, reducing the risk of cross-contamination, while glass pasteur pipettes can be sterilized and reused, providing an eco-friendly option. Sterile pasteur pipettes ensure that samples remain uncontaminated during transfer, a critical factor in sensitive experiments.

– Dual bulb pipettes are used to deliver a fixed, small, measured volume of liquid.
– Simply squeeze the upper bulb to fill, and squeeze again to dispense the precise volume.
– Also known as exact volume pipettes, these space-saving, economical, single-piece,disposable liquid transfer devices are a quick and easy alternative to conventional pipettes and tips.

Built for Repeatable Accuracy

• Material: Low-density polyethylene (LDPE), non-toxic, chemically resistant to acids, alkalis, and most biological reagents — safe for both diagnostic samples and lab chemical transfer.
• Single-piece, unbreakable design: No separate bulb or tip to fit, reducing both your assembly-line handling steps and your packaging cost per unit.
• High-clarity body: Transparent construction for visual confirmation of sample or reagent fill.
• Sterile and non-sterile formats: Bulk poly-bag packing for non-sterile stock orders, individually wrapped for sterile diagnostic-kit inclusion.

Full Specification Range

Application

• Rapid/POC diagnostic kit manufacturers — antigen, pregnancy, ovulation, and other lateral-flow self-test kits that need a fixed-volume sample dropper untrained end-users can operate correctly on the first try.
• Clinical and molecular biology labs — fast, tip-free reagent or sample transfer where a full micropipette is unnecessary overhead.
• Veterinary and agricultural testing — field or barn-side sample collection where breakage risk with glass tools is a real operating cost.
• Water, environmental, and food-safety testing — chemical-resistant single-use transfer for reagent addition in the field or in QC labs.

Why B2B Buyers Source This Exact Volume Transfer Pipette From ApsNesswell

• Manufacturer, not a trading middleman on this line. We produce this pipette in-house, which means we control the mold, the resin batch, and the wall-thickness tolerance that determines dispensing accuracy — the variable most private-label buyers actually care about but rarely get visibility into.
• A wider volume range than most standard catalogs. Our lineup runs 50µL to 650µL across 11 fixed volumes, while most standard exact-volume pipette ranges on the market stop around 300–400µL. If your kit needs a larger fixed draw (reagent addition, buffer dispensing), you likely don’t need a second supplier for that.
• Mold-based OEM and private label. Volume, stem length, printing, and packaging format can be customized against your own mold specification — relevant if this pipette will carry your own kit brand rather than ours.
• One-stop consumable sourcing. Because we also supply the adjacent items your lab or kit-assembly line typically orders in the same PO, you can consolidate freight and supplier vetting instead of managing multiple factories for one shipment.
• Sample-first evaluation. Free samples are available within a reasonable quantity so your QC team can validate dispensing accuracy before committing to a production order.

Sourcing FAQ

Is this Exact Volume Transfer Pipette  available sterile?
Yes. Non-sterile stock is bulk poly-bag packed; sterile units are individually wrapped for direct inclusion in a diagnostic kit assembly line.

Can the volume or stem length be customized?
Yes, against a new mold. Share your target volume and length and we’ll confirm mold lead time and MOQ.

What’s the sample process before a bulk order?
Free samples are provided within a reasonable quantity so you can verify dispensing accuracy and material feel before placing a production PO.

What are the typical lead time and payment terms?
Standard stock orders ship in 5–35 working days depending on quantity and customization; T/T, PayPal, and L/C are accepted, with other terms negotiable for established buyers.

How is this shipped internationally?
Sea freight is recommended for large-volume orders; DHL/FedEx by air or express is available for smaller, time-sensitive shipments.
