Scientific communities are drawn to the open source model as an increasingly utilitarian method to produce and share work. Initially used as a means to develop freely-available software, open source projects have been applied to hardware including scientific tools. Increasing convenience of 3D printing has fueled the proliferation of open labware projects aiming to develop and share designs for scientific tools that can be produced in-house as inexpensive alternatives to commercial products. We present our design of a micropipette that is assembled from 3D-printable parts and some hardware that works by actuating a disposable syringe to a user-adjustable limit. Graduations on the syringe are used to accurately adjust the set point to the desired volume. Our open design printed micropipette is assessed in comparison with a commercial pipette and meets the ISO 8655 standards.
科学界越来越倾向于将开源模式作为一种生产和分享成果的实用方法。开源项目最初被用作开发免费软件的手段，如今已应用于包括科学工具在内的硬件领域。3D打印便利性的提高推动了开放式实验室器具项目的发展，这些项目旨在开发和分享科学工具的设计，以便内部制造，作为商业产品的廉价替代品。我们展示了一种微量移液器的设计，它由3D可打印部件和一些硬件组装而成，通过将一次性注射器驱动到用户可调节的限度来工作。注射器上的刻度用于将设定点精确调整到所需体积。我们的开放式设计打印微量移液器与商用移液器相比进行了评估，并符合ISO 8655标准。
