The 5mL individually packaged sterile serological pipette belongs to small-caliber high-precision laboratory liquid transfer consumables, which is the universal standard specification for daily operation in life science labs, pharmaceutical testing institutions, hospital clinical labs, food inspection and microbiology research rooms. Compared with 1mL ultra-small pipettes and 10mL medium pipettes, the 5mL model balances ultra-fine 0.1mL graduation accuracy and moderate liquid volume transfer capacity, perfectly matching high-precision quantitative demands of cell passage, reagent formulation, bacterial suspension inoculation, ELISA reagent adding and small-volume supernatant collection.
The whole tube is printed with dense black graduation lines with 0.1mL minimum scale interval, marked as “5mL in 1/10mL” on the outer packaging. All scale printing uses high-adhesion solvent-resistant ink, which will not fade, smudge or fall off after long-term contact with complete medium, PBS buffer, ethanol, weak organic solvents and diluted acid solutions, guaranteeing consistent reading accuracy for repeated batch testing experiments. A light blue circular ring is set at the top connecting end, following the international unified color marking rule for serological pipettes; lab technicians can rapidly distinguish it from orange 10mL, red 25mL, blue 50mL and yellow 100mL pipettes to prevent wrong selection in busy laboratory workflows.
Each pipette is separately sealed in breathable sterile peel pouch, with production batch number, expiry date, STERILE certification and Non-pyrogenic logo printed on the package for complete batch traceability. All finished products are sterilized by EO gas in Class 100,000 dust-free purification workshops, and each batch undergoes strict sterility inspection and bacterial endotoxin testing before delivery, reaching cell-grade aseptic level suitable for sensitive mammalian cell culture experiments. This pipette adopts globally recognized blow-out calibration standard: the tiny residual liquid retained at the tapered tip must be manually blown out via a pipette controller to achieve the accurate 5mL nominal volume, fully complying with international laboratory volumetric pipetting operation specifications.

First, ultra-fine scale for superior quantification precision. The 0.1mL minimum graduation greatly improves the accuracy of small-volume liquid preparation, minimizing systematic errors in biochemical detection, microbial counting and cell culture medium proportion configuration.
Second, strict aseptic control for sensitive experiments. Independent sealed packaging eliminates secondary pollution risks during transportation and storage; non-pyrogenic and non-cytotoxic properties will not inhibit cell viability in transfection, cloning and drug screening experiments.
Third, stable chemical inertness of raw material. Medical PS material does not dissolve or precipitate harmful substances when contacting most common lab aqueous reagents, effectively protecting precious biological samples from contamination.
Fourth, user-friendly packaging and structural design. The tearable single sterile bag can be opened without sharp blades, complying with GMP cleanroom sterile operation guidelines. The slim tapered tip can extend deep into centrifuge tubes, cell culture flasks, EP tubes and narrow-neck reagent bottles for splash-free stable liquid transfer.
Fifth, powerful universal compatibility. It can be directly fitted with almost all mainstream manual pipette fillers and electric pipette pumps on the market without extra adapters, featuring tight sealing and smooth suction-liquid discharge performance.
This 5mL sterile serological pipette is widely applied across multiple professional industries: cell subculture and small-scale medium replacement in biotechnology laboratories, reagent adding for ELISA and biochemical kits in pharmaceutical testing labs, bacterial suspension transfer and agar medium dispensing in microbiology laboratories, teaching experiment solution preparation for university life science majors, clinical serum aliquoting in hospital inspection departments, sample pretreatment for cosmetic efficacy testing, and standard liquid configuration for food safety and pesticide residue detection institutions.
A1: Absolutely not. It is a single-use disposable lab consumable. High-temperature autoclaving will cause tube deformation, scale peeling and sterility failure, leading to cross-contamination of experimental samples, so reuse is prohibited.
A2: The light blue ring is the international color code for 5mL serological pipettes, designed for quick visual identification of different volume specifications to avoid operational errors.
A3: Yes. The product is EO sterilized, non-pyrogenic and passed cytotoxicity test, fully safe for cell passage and small volume liquid transfer in cell culture experiments.
A4: It means the minimum graduation value of this pipette is 0.1 milliliter, supporting precise quantitative adjustment per 0.1 mL unit.
