The Nees-Institu for Plant Biodiversty applies for a Scanning Electron Microscope with energy.-disperive X-ray spectroscopy (EDX) and a kryo-setup as a replacement for an older modell SEM (Leo 1450). SDcanning electron microscopy is - next to modern phylogenetics - a crucial technique for the research carried out at the Nees Institute and is emploeyd in a wide range of projects on taxonomy, morphology and systematics. In biology, scanning electron microscopy is the crucial instrument for investigating the (functional) morphology of biological surfaces, such as leaf surfaces with their trichomoes, cuticular waxes and epiphyllous bacteria, bones and generally small structures be it fruits, flowers, the gametophytes/sporophytes of early land plants, teeht, mouth parts of insects or other invertebrates. The requetsed special features of the new instrument additionally permit the thes tudy of biological objects without previous dehydration (Kryo-SEM) resp. permit the investigation of the chemcial make-up with a combination of material contrast (BSE) and x-ray spectroscopy (EDX). The Nees Institute has operated a unit for scanning electron micrscopy for the past decades. SEM is widely used in our own research, but also in the research of other working groups in the Fachgruppe Biologie and the agriculatural faculty and international collaborations. The machines currently available at the Nees Institute are long past their prime, but one of them will be kept up and runing mainly for teaching purposes. Access to the unit for Scanning Electron Microscopy at the Nees Institute is regulated by the user regulation of the "virtual Centre for Advanced Imaging in the Biology Section (AImBioS). This governs both access by other working groups, Institutes and extrenal users to the unit and ensures a high usage rate.

植物生物多样性的需要-Incuberu申请扫描电子显微镜与能源。disperive X射线光谱（EDX）和kryo装置作为旧型号SEM（Leo 1450）的替代品。SDCanning电子显微镜技术是Nees研究所进行的研究的关键技术，仅次于现代遗传学，并广泛应用于分类学，形态学和系统学的项目中。在生物学中，扫描电子显微镜是研究生物表面（功能）形态的重要工具，例如具有毛状体的叶表面，表皮蜡和叶附生细菌，骨骼和通常小的结构，例如水果，花，早期陆地植物的配子体/孢子体，teeht，昆虫或其他无脊椎动物的嘴部。新仪器所需的特殊功能还允许在没有预先脱水的情况下对生物物体进行研究（Kryo-SEM）。允许使用材料对比（BSE）和X射线光谱（EDX）的组合来研究化学组成。在过去的几十年里，Nees研究所一直在经营一个扫描电子显微镜的单位。SEM广泛用于我们自己的研究，也用于Fachgruppe Biologie和农学院其他工作组的研究以及国际合作。尼斯研究所现有的机器早已过了全盛时期，但其中一台将继续运行，主要用于教学目的。进入Nees研究所的扫描电子显微镜单元受“生物科高级成像虚拟中心”用户条例的管制。这就控制了其他工作组、研究所和外部用户对该单位的访问，并确保了高使用率。
