The CD 250<\/a> 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 \u00b0C to 105 \u00b0C. With the correct carriage design and sample, extend temperature ranges to below -40 \u00b0C or up to 150 \u00b0C. 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 \u662f\u4e00\u4e2a\u72ec\u7acb\u7684\u652f\u67b6, \u53ef\u6839\u636e\u9700\u8981\u4e3a\u5404\u79cd\u8bd5\u5242\u76d2\u6216\u5176\u4ed6\u6837\u54c1\u63d0\u4f9b\u6e29\u5ea6\u63a7\u5236\u3001\u5e72\u6c14\u51c0\u5316\u548c\u78c1\u6405\u62cc\u3002\u8fd9\u79cd\u591a\u529f\u80fd\u6027\u662f\u901a\u8fc7 cd 250 \u7684\u6e29\u5ea6\u63a7\u5236\u5854\u5185\u7262\u56fa\u5730\u5b89\u88c5\u5728 cd 250 \u5185\u7684 cuvette \u6258\u67b6\u6765\u5b9e\u73b0\u7684\u3002\u7acb\u65b9\u8f66\u53a2\u53ef\u7528\u4e8e\u51e0\u79cd\u7c7b\u578b\u7684\u7acb\u65b9, \u5305\u62ec\u6b63\u65b9\u5f62\u3001\u957f\u65b9\u5f62\u6216\u5706\u67f1\u5f62\u7684\u5207\u5272\u673a, \u4ee5\u53ca\u5176\u4ed6\u6837\u54c1, \u5982\u5c0f\u677f\u6216\u8584\u819c\u3002\u5176\u4ed6\u8f66\u53a2\u53ef\u6839\u636e\u9700\u8981\u8fdb\u884c\u4f4e\u6210\u672c\u8bbe\u8ba1\u3002\u7194\u878d\u7a97\u53ef\u4ee5\u653e\u7f6e\u5728\u6837\u54c1\u6216\u7acb\u65b9\u7684\u6bcf\u4e00\u4fa7, \u4ee5\u6700\u5927\u9650\u5ea6\u5730\u51cf\u5c11\u5bf9\u6d41\u635f\u5931\u3002\u4f7f\u7528 cd 250 \u4e3b\u8981\u7528\u4e8e\u5438\u6536\u6d4b\u91cf, \u4f46\u6839\u636e\u6258\u67b6\u8bbe\u8ba1, \u53ef\u572890\u5ea6\u7684\u6fc0\u53d1\u4e0b\u589e\u52a0\u4e00\u4e2a\u5149\u5b66\u7aef\u53e3, \u7528\u4e8e\u89c2\u5bdf\u8367\u5149\u6216\u5149\u5316\u5b66\u6fc0\u53d1\u3002\u4f7f\u7528 cd 250 \u57280\u00b0c \u81f3105\u00b0c \u7684\u751f\u7269\u8303\u56f4\u5185\u5de5\u4f5c\u3002\u901a\u8fc7\u6b63\u786e\u7684\u6258\u67b6\u8bbe\u8ba1\u548c\u6837\u54c1, \u5c06\u6e29\u5ea6\u8303\u56f4\u6269\u5c55\u5230-40\u00b0c \u4ee5\u4e0b\u6216\u9ad8\u8fbe150\u00b0c\u3002\u4f7f\u7528\u83dc\u5355\u6309\u94ae\u64cd\u4f5c tc \u534a\u6e29\u5ea6\u63a7\u5236\u5668, \u901a\u8fc7\u53ef\u9009\u7a0b\u5e8f t-app \u8fdb\u884c\u63a7\u5236, \u6216\u7f16\u5199\u81ea\u5df1\u7684\u7a0b\u5e8f\u8fdb\u884c\u63a7\u5236\u3002<\/p>\n
