Scanning electron microscope with low vacuum mode, EDX analytics system and EM sample preparation (critical point dryer and high vacuum coater)

拜罗伊特大学生物系电子显微镜重点实验室支持所有需要透射或扫描电子显微镜的生命科学工作组。此外，重点实验室开展自己的研究项目，并在一个中央项目中支持超区域DFG研究单位FOR 2092。重点实验室的扫描电镜已于2016年退役，因为它技术过时，容易受到干扰，因此无法再经济地操作。将原有的电子显微镜替换为此处使用的设备，以保留重点实验室的扫描电子显微镜和能量色散x射线光谱学。此外，它打算用最先进的临界点干燥机和高真空镀膜机取代过时的样品制备设备。所要求的设备的必要性主要是基于这样一个事实，即近年来几个新的工作组加入了生物系，其当前和计划的研究项目（例如SFB 1357）需要大量使用扫描电子显微镜。许多项目需要非常耗时的测量，例如对形态特征的量化或对方法的开发和改进。由于拜罗伊特大学现有的扫描电子显微镜的使用率很高，因此无法提供必要的测量时间。因此，这里应用的设备对于当前和未来的研究项目的实现至关重要。

The Key Lab Electron Microscopy of the biological department at the University of Bayreuth supports all working groups in life sciences that require transmission or scanning electron microscopy. In addition, the Key Lab carries out its own research projects and supports the supra-regional DFG research unit FOR 2092 in a central project. The scanning electron microscope in the Key Lab was decommissioned in 2016 because it was technically outdated and highly prone to interference and could therefore no longer be operated economically. The original electron microscope is intended to be replaced by the device applied for here, and thus to keep scanning electron microscopy and the energy dispersive X-ray spectroscopy available in the Key Lab. Additionally, it is intended to replace the outdated sample preparation equipment with the state-of-the-art critical point dryer and the high vacuum coater applied for here. The necessity for the requested device is mainly based on the fact that several new working groups have joined the biology department in recent years, whose current and planned research projects (e.g. SFB 1357) require intensive use of scanning electron microscopy. Many projects require very time consuming measurements, e.g. for the quantification of morphological features or to the development and refinement of methods. Due to the very high utilization of the scanning electron microscopes already available at the University of Bayreuth, the necessary measuring time cannot be provided. Therefore, the device applied for here is of utmost importance for the realization of current and future research projects.
