Products Serological pipettes from Zhejiang Liquan Biotechnology Co., Ltd. enable clean, accurate liquid transfer for cell culture, IVD workflows, pharmaceutical R&D, and teaching labs. We manufacture 1, 2, 5, 10, 25, and 50 mL sizes in high-clarity polystyrene with color-coded sleeves and crisp graduations. Sterile, RNase/DNase-free and nonpyrogenic options support sensitive work. Choose individually wrapped or bulk packs to fit your bench practice. Production follows ISO13485 and ISO9001, with lot-level traceability for quality control.
Graduation layouts include reverse and negative scales for fast read-down from full volume. Solvent-resistant inks and precise alignment improve legibility at 20°C. Optional polyester plugs help protect controllers from aerosol or liquid ingress.
Rigid barrels ensure a secure fit with standard manual or motorized controllers and smooth, consistent flow. Each item can be supplied with LOT and expiry details for inventory and audit needs.
Accuracy is verified against industry norms at full volume. Reverse graduations simplify setting and help control residual volume. High-contrast markings support confident meniscus reading.
Disposable polystyrene provides excellent transparency and smooth wetting. Sterile versions are gamma processed with supporting documents available. Non-sterile options serve routine or teaching applications.
Use these graduated transfer pipettes for media changes, cell suspensions, buffer preparation, serial dilutions, and sample handling. Universal shafts fit widely used pipette controllers in biosafety cabinets and production suites.
Select capacity, sterility, graduation style, and plug type to match your protocol and environment.
| Volume | Typical Use | Notes |
|---|---|---|
| 1 mL | Enzyme additions, small aliquots | Fine graduations for precision |
| 2 mL | Reagent additions | Quick identification by color |
| 5 mL | Wash steps, buffers | Balanced speed and control |
| 10 mL | Routine media transfer | Common in tissue culture |
| 25 mL | Media prep, supernatant removal | Reverse/negative graduations |
| 50 mL | Bulk handling | Maximize throughput |
Pick plugged formats for contamination control or unplugged versions for economy. Choose individually wrapped for aseptic entry or bulk packs for speed at high-throughput benches.
With in-house mold design, plastic molding, and R&D, Liquan supports private label and customization. We tailor graduations, ink, branding, plug type, and packaging to your specification, and align documentation to program needs. Stable capacity and ISO13485 controls support consistent supply.
