The 2mL individually packaged sterile serological pipette fills the volume gap between 1mL micro pipettes and 5mL medium-capacity pipettes, being one of the most frequently used general specifications in biological laboratories, pharmaceutical R&D labs, hospital clinical testing rooms and food safety inspection departments. With a delicate 0.02mL minimum graduation, it balances trace quantification accuracy and moderate liquid transfer volume, perfectly matching daily operations such as partial medium change for adherent cell lines, multiple reagent blending, quantitative transfer of bacterial suspensions, supernatant collection after centrifugation and standard solution preparation for biochemical assays.
The pipette body is injection molded with high-transparency medical polystyrene resin, featuring high structural rigidity and clear liquid level observation effect. Operators can directly check the liquid meniscus inside the tube during suction and discharge to avoid reading deviation. The dense black graduation lines run through the whole tube, marked “2mL in 1/50mL” on the outer package to indicate 0.02mL scale interval. All scale marks are printed with high-adhesion solvent-resistant ink, which will not dissolve or fade when exposed to cell culture medium, PBS buffer, ethanol and weak organic solvents, guaranteeing long-term reading stability for repeated experimental batches. A green circular ring is set at the top connector following the international unified color marking system for serological pipettes; lab staff can rapidly distinguish it from yellow 1mL, blue 5mL, orange 10mL pipettes to prevent wrong picking in busy experimental workflows.
Each unit is sealed separately in breathable peelable sterile packaging, with batch number, expiry date, STERILE mark and Non-pyrogenic logo printed on the pouch for complete batch traceability. All finished goods are EO gas sterilized in Class 100,000 dust-free purification workshops, with each batch undergoing sterility inspection and bacterial endotoxin testing before delivery. It reaches cell-grade aseptic level and can be safely applied to sensitive mammalian cell culture and low-toxicity biological experiments. This pipette adopts globally accepted blow-out calibration standard: the residual tiny liquid retained in the tapered tip must be fully blown out by a pipette controller to achieve accurate 2mL nominal volume, complying with international volumetric pipetting operation specifications.

Moderate volume with high precision: 0.02mL fine scale greatly reduces manual operation errors in medium proportioning and microbial counting.
Strict aseptic performance: Independent sealed package avoids secondary pollution during storage and transportation; non-cytotoxic and non-pyrogenic properties will not affect cell viability in transfection and drug screening tests.
Stable chemical compatibility: Medical PS material is inert to most aqueous laboratory reagents, preventing sample contamination caused by material precipitation.
Humanized operation design: Tearable sterile bag does not require sharp cutting tools, complying with GMP cleanroom operation standards; slender tapered tip can reach deep into cell culture flasks, centrifuge tubes and reagent bottles for splash-free liquid transfer.
Wide equipment compatibility: Directly compatible with all mainstream manual pipette fillers and electric pipette pumps on the market, with tight sealing and smooth suction & discharge performance.
This 2mL serological pipette is widely used for cell partial medium replacement in biotechnology labs, reagent distribution for pharmaceutical detection kits, quantitative inoculation in microbiology labs, teaching experiment liquid preparation for universities, clinical sample aliquoting in hospital laboratories, cosmetic safety testing sample pretreatment and pesticide residue detection standard liquid configuration.
A1: Not allowed. It is a single-use disposable consumable. High temperature and pressure sterilization will cause tube deformation and scale falling off, leading to cross-contamination of samples.
A2: Green ring is the international color code for 2mL serological pipette, used for fast visual identification of volume specifications.
A3: Yes, EO sterilized, non-pyrogenic and cytotoxicity tested, safe for cell passage and medium changing operations.
A4: It means the minimum graduation of the pipette is 0.02 mL for precise quantitative liquid transfer.
