QNW 支架 光学支架 CD250样品池支架 精密温控样品池支架

The CD 250 is a standalone holder that provides temperature control, dry gas purging and magnetic stirring as needed to a wide range of cuvettes or other samples. This versatility is accomplished using a cuvette carriage which firmly mounts within the temperature controlled tower of the CD 250. Cuvette carriages are available for several kinds of cuvettes, including those that are square, rectangular or cylindrical, as well as other samples such as small plates or films. Other carriages can be inexpensively designed as needed. Fused silica windows may be placed on each side of the sample or cuvette to minimize convection losses. Use the CD 250 primarily for absorbance measurements, although depending on the carriage design, an additional optical port at 90 degrees to the excitation may be available for observation of fluorescence or photochemical excitation. Use the CD 250 for work in the biological range of 0 °C to 105 °C. With the correct carriage design and sample, extend temperature ranges to below -40 °C or up to 150 °C. Operate the TC 1/Single Temperature Controller using the menu button, control via optional program T-App, or write your own program for control.cd250 是一个独立的支架, 可根据需要为各种试剂盒或其他样品提供温度控制、干气净化和磁搅拌。这种多功能性是通过 cd 250 的温度控制塔内牢固地安装在 cd 250 内的 cuvette 托架来实现的。立方车厢可用于几种类型的立方, 包括正方形、长方形或圆柱形的切割机, 以及其他样品, 如小板或薄膜。其他车厢可根据需要进行低成本设计。熔融窗可以放置在样品或立方的每一侧, 以最大限度地减少对流损失。使用 cd 250 主要用于吸收测量, 但根据托架设计, 可在90度的激发下增加一个光学端口, 用于观察荧光或光化学激发。使用 cd 250 在0°c 至105°c 的生物范围内工作。通过正确的托架设计和样品, 将温度范围扩展到-40°c 以下或高达150°c。使用菜单按钮操作 tc 半温度控制器, 通过可选程序 t-app 进行控制, 或编写自己的程序进行控制。
