The Versa 20 is a standalone version of a versatile cuvette holder for absorbance measurements mounted on a simple base with a hole pattern for attachment to an optical breadboard. With optical ports on each side of the cuvette, use the Versa 20 for absorbance measurements or other experiments in which laser beams or other light is passed through the cuvette from one side to the other. The Versa 20 is ideal for work in the biological range of 0 °C to 110 °C, either to observe absorbance spectra at precisely maintained temperatures, or for temperature ramping, to observe how absorbance changes with temperature. To work at cold temperatures, purchase a Windowed Jacket, purge with dry gas and work down to -40 °C. For even more demanding work, purchase the extended temperature option and run the Versa 20 up to 150 °C or down to below -40 °C. The lowest effective temperature for working with the Versa 20 will depend on the conditions in the laboratory and how well the cuvette holder isolated from the ambient environment. To control the Versa 20, use the menu button on the TC 1/Single Temperature Controller, run Quantum Northwest’s program T-App, or write your own program for control.versa 20 是一个独立版本的多功能立方支架, 用于吸收测量, 安装在一个简单的底座上, 带有孔图案, 可连接到光学面包板上。在 cuvette 的每一侧都有光学端口时, 使用 versa 20 进行吸收测量或其他实验, 在这些实验中, 激光束或其他光从一个侧面传递到另一侧。versa 20 是在0°c 至110°c 的生物范围内工作的理想选择, 可以在精确保持温度下观察吸收光谱, 也可以观察温度的变化, 以观察吸收率如何随温度变化。要在低温下工作, 请购买风式夹克, 用干气清洗, 工作温度降低到-40°c。对于要求更高的工作, 请购买延长温度选项, 并在150°c 或-40°c 以下运行 versa 20。使用 versa 20 的最低有效温度将取决于实验室的条件以及与周围环境隔离的 cuvette 支架的情况。要控制 versa 20, 请使用 tc 半温度控制器上的菜单按钮, 运行昆腾西北的程序 t-app, 或编写自己的程序进行控制。
