Ultraviolet–visible (UV–vis) spectroscopy represents one of the most popular analytical techniques in chemical research labs. A variety of vendors provide instruments that are suited for the analysis of liquid samples at moderate concentrations. However, to accommodate more specialized experiments, expensive accessories are required and often do not fit the specific needs of experimental scientists. In this work, we present a generalized adapter that can be 3D printed and used with existing spectrometers to enable a wide array of experiments to be performed. In the case of liquid samples, we provide a method for dramatically reducing the price of a quartz cuvette with minimal impact on performance. Through simple modification of the design, cuvettes with various path lengths can be prepared. Additionally, we illustrate the ability to turn any sample container into a working cuvette to simplify experimental protocols, prevent contamination risks, and further reduce costs. This strategy also enables gaseous and solid samples to be evaluated easily and reproducibly. Furthermore, we demonstrate how this concept can be extended to interface additional instrumentation with a commercial UV–vis spectrometer. All of the digital designs are provided under a creative commons license to enable other researchers to modify and adapt the designs for their unique experimental requirements.

用于低成本和多功能光谱实验的3D打印紫外可见比色皿适配器

紫外可见光谱是化学研究实验室中最流行的分析技术之一。许多供应商提供了适用于分析中等浓度液体样品的仪器。但是，为了适应更专业的实验，需要昂贵的附件，并且通常不符合实验科学家的特定需求。在这项工作中，我们提出了一种通用适配器，该适配器可以进行3D打印并与现有的光谱仪配合使用，以进行各种各样的实验。对于液体样品，我们提供了一种在不影响性能的情况下大幅降低石英比色皿价格的方法。通过简单的设计修改，可以制备出具有各种光程长度的比色皿。此外，我们展示了将任何样品容器变成工作比色皿的能力，从而简化了实验规程，防止了污染风险并进一步降低了成本。这种策略还可以轻松，可重复地评估气态和固态样品。此外，我们演示了如何将这个概念扩展到与商用紫外可见光谱仪对接附加仪器的接口。所有数字设计均根据知识共享许可提供，以使其他研究人员能够根据其独特的实验要求修改和调整设计。我们演示了如何扩展该概念，以将其他仪器与商用UV-vis光谱仪对接。所有数字设计均根据知识共享许可提供，以使其他研究人员能够根据其独特的实验要求修改和调整设计。我们演示了如何扩展该概念，以将其他仪器与商用UV-vis光谱仪对接。所有数字设计均根据知识共享许可提供，以使其他研究人员能够根据其独特的实验要求修改和调整设计。
