These disposable serological pipettes are fabricated from medical-grade polystyrene for single-use liquid measurement and transfer in clinical, research, and industrial testing laboratories. Each pipette is pre-sterilized via gamma irradiation and supplied individually wrapped, eliminating cross-contamination risk for sensitive experimental workflows. The design supports use with standard pipette aids and manual pipette pumps for volumes ranging from 1mL to 50mL. These consumables support consistent throughput for commercial procurement in diagnostic laboratories, pharmaceutical manufacturing, and food testing facilities.
Volume accuracy is rated at ±0.5% with precision of ±0.3% at the nominal full volume, measured according to ISO 8655-5 standards for graduated pipettes. Dual-sided graduation marks are printed with fade-resistant ink for readability from multiple operator positions. The tapered tip design supports clean dispensing without droplet retention.
Polystyrene construction provides clarity for visual meniscus reading and chemical compatibility with aqueous solutions, dilute acids, and biological buffers. Gamma irradiation sterilization achieves a Sterility Assurance Level (SAL) of 10⁻⁶ per ISO 11137 standards. Each unit is individually sealed in peelable packaging to maintain sterility until point of use.
The inner bore surface undergoes hydrophobic treatment to minimize liquid adhesion. Measured liquid recovery exceeds 99% for aqueous solutions tested at 20°C, reducing sample loss for precious or trace-volume specimens in analytical and clinical testing applications.

All pipettes include a fiber plug at the upper end to prevent over-aspiration and aerosol contamination of pipette controllers. The widened top collar forms a secure fit with all standard pipette pump and electronic pipette aid connectors on the market.
Clinical laboratories use these pipettes for antibody titer determination, antigen quantification, and ELISA sample preparation. Precise serum and plasma dilution ratios support consistent immunoassay results for diagnostic testing and disease screening operations.
Microbiology and cell culture facilities apply the pipettes for media dispensing, bacterial inoculation, and cell suspension transfer. Pre-sterilized packaging supports direct use within aseptic workflows, reducing preparation time for high-throughput culture operations.
Biochemistry and molecular biology laboratories utilize the pipettes for reagent distribution, sample dilution, and lysate transfer during protein extraction, PCR setup, and nucleic acid purification. Single-use format eliminates carryover between sample batches.
Pharmaceutical manufacturing and quality control departments use these pipettes for content uniformity testing, impurity analysis, and standard solution preparation. Documented sterilization and calibration specifications support compliance requirements for regulated industrial production environments.
University and independent research laboratories deploy the pipettes for routine liquid handling tasks including standard curve preparation, titration procedures, and chromatography sample loading. The range of available volumes covers most general experimental requirements.
Production occurs within Class 100,000 cleanroom facilities to minimize particulate contamination during assembly. Each production lot undergoes 100% leak testing and dimensional verification before packaging.
Lot-specific test reports are available upon request for volume orders, including sterilization batch records and dimensional verification data. This documentation supports quality management system requirements for accredited testing and manufacturing facilities.
Materials meet USP Class VI biocompatibility standards for plastic components used in laboratory and medical applications. The manufacturing facility operates under ISO 13485 quality management system guidelines for medical device production.
