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 是一個獨立版本的多功能立方支架, 用于吸收測量, 安裝在一個簡單的底座上, 帶有孔圖案, 可連接到光學(xué)面包板上。在 cuvette 的每一側(cè)都有光學(xué)端口時, 使用 versa 20 進行吸收測量或其他實驗, 在這些實驗中, 激光束或其他光從一個側(cè)面?zhèn)鬟f到另一側(cè)。versa 20 是在0°c 至110°c 的生物范圍內(nèi)工作的理想選擇, 可以在精確保持溫度下觀察吸收光譜, 也可以觀察溫度的變化, 以觀察吸收率如何隨溫度變化。要在低溫下工作, 請購買風(fēng)式夾克, 用干氣清洗, 工作溫度降低到-40°c。對于要求更高的工作, 請購買延長溫度選項, 并在150°c 或-40°c 以下運行 versa 20。使用 versa 20 的最低有效溫度將取決于實驗室的條件以及與周圍環(huán)境隔離的 cuvette 支架的情況。要控制 versa 20, 請使用 tc 半溫度控制器上的菜單按鈕, 運行昆騰西北的程序 t-app, 或編寫自己的程序進行控制。
