In molecular biology laboratories, many tasks require fine motor control and high acuity vision. For example, lab technicians with visual impairment experience difficulty loading samples into the small wells of a horizontal agarose gel. We have developed a 3D-printable gel loading system which allows technicians with low-contrast vision to load gels correctly. It includes a casting tray, a bridge, and a modified comb. The system provides a high-contrast visual field to improve visibility, and the bridge allows pipette tips to be inserted at the correct location and only to the correct depth. The necessary computer files for printing this device are freely available to increase the accessibility of molecular biology laboratories to people with visual impairment.

用于凝胶电泳的 3D 打印辅助移液系统，适用于视力低下的技术人员。

在分子生物学实验室中，许多任务需要精细的运动控制和高敏锐度的视觉。例如，有视力障碍的实验室技术人员很难将样品装入水平琼脂糖凝胶的小孔中。我们开发了一种 3D 可打印凝胶加载系统，该系统允许具有低对比度视力的技术人员正确加载凝胶。它包括一个铸造托盘、一个桥和一个改进的梳子。该系统提供了一个高对比度的视野以提高可见度，并且桥接器允许将移液器吸头插入正确的位置，并且只能插入正确的深度。免费提供打印此设备所需的计算机文件，以增加分子生物学实验室对视力障碍人士的访问。
