The BIO-1 pipette delivers exceptional solvent and acid-alkali resistance thanks to its unique structural design. Its lower part can be directly subjected to high-temperature and high-pressure sterilization, and each unit is strictly calibrated in accordance with the ISO 8655 standard, balancing durability and accuracy. In terms of detailed design, it is equipped with a telescopic conical nozzle and a pulley-type tip ejector, making tip attachment and ejection more convenient and smooth. The core components are precision-machined from metal screws, with a part accuracy of up to 0.001mm, providing extraordinary accuracy for various liquid transfer tasks. Additionally, models with a volume of 10μl and above are fitted with hydrophobic filters, which reduce the risk of contamination from internal components of the pipette. Covering a single-channel volume range from 0.1μl to 10ml, the BIO-1 pipette meets the pipetting needs of multiple laboratory scenarios, achieving an efficient integration of performance and applicability.
