Details
Cap Only, Green
Features:
The cap is molded with an o-ring seal and a deep internal lip that fits snugly against the interior wall of the tube thus preventing the contents from coming in contact with the seal or threads, thereby reducing the chances of sample contamination. These flat caps will accommodate automatic capping machines.
Certified RNase-, DNase-, Pyrogen- and DNA-free.

SIM 凝胶、化学发光图像分析系统为科学家提供了一种新一代36Bit,Bio-1DExpress软件,Windows98/2000/XP均兼容,能够观察分析各种透明或不透明的电泳图像,如EB染色胶,蛋白胶,放射自显影、印迹、斑点印迹等,满足定性,定量分析的迫切需要。
为凝胶图像分析提供了先进,操作简便的解决方法。
为广大从事分子生物学、医院临床检验、法医物证的研究人员提供了一个快捷的解决方式。
它给出更简便、更迅速及更准确的方式以再现、收集、分析图像中的细节。
由图像拍摄、图像处理、数据分析、报告打印等组成一体,符合常规实验的操作思路,做到方便、实用、简单有助于研究人员的正确、迅速地得到凝胶电泳结果照片和分析的其迅速、强大、准确、可靠、经过实践检验,能够使工作更加容易,更加有效。
请问成像系统工作站请问那家的产品做得比较好以及专业一些呢?

样品对投射或者反射光有部分的吸收,从而照相所得到的图像上面的样品条带的光密度就会有差异。光密度于样品的浓度或者质量成线性关系。根据未知样品的光密度,通过于已知浓度的样品条带的光密度指相比较就可以得到未知样品的浓度或者质量。这就是图像分析系统定量的基础。采用最新技术的紫外透射光源和白光透射光源使光的分布更加均匀,最大限度的消除了光密度不均造成的对结果的影响。向左转|向右转
请问各位,我在显微镜下拍的100倍、400倍图片,图片右下角标尺都是200um,是什么意思?谢谢解答。
