Specimens of interest to researchers are sometimes incompatible with the strict sample requirements of an electron microscope and may require several preparation steps before their intimate structure can be observed and resolved. They may be outgassing when placed in the vacuum of the EM, or be charging up under the electron beam and cause image artifacts or they might be simply too big or too thick to fit in the EM chamber. We offer a portfolio of different products to address these issues. Some of these products are multi-functional and may appear in more than one category.
When a high throughput of sample preparation is required in a lab, automation of sample preparation is very important. Not only in terms of high volume of samples prepared, but also for reproducibility and reliability of the preparation methods.
Metal coating or carbon evaporation is often an unavoidable step before visualizing your specimen in a SEM or TEM. We selected a variety of products from leader manufacturers capable to fit all your needs.
Hydrated samples cannot be placed directly under vacuum and have to be fixed or dried gently in order to preserve their structure. Critical point drying or freeze drying are two methods that can be used for many biological specimens (see also here). Our equipment represent the perfect choice for preparing and stabilizing your samples.
Hydrated samples cannot be placed directly under vacuum and have to be fixed or dried gently in order to preserve their structure. Plunge freezing or high pressure freezing are two methods that can be used for many biological specimens (see also here). Compared to drying method, this technique preserves the specimens in a state much closer to the native state. The disadvantage is that samples have to be kept at cryogenic temperatures for the duration of the analysis.
Glow discharge from a plasma can be used to modify surfaces, for example to enhance polymer bonding, or on TEM support films and grids to render them hydrophilic and facilitate wetting. Different types of surface modifications can be brought about with different gas mixtures or chemicals used for the creation of the plasma. A plasma of the appropriate composition and energy can be used to gently remove contamination from your samples or to selectively etch layers or to reduce organic material to ashes.
Argon milling is a very effective polishing method used to thin a TEM sample to electron transparency or to remove/avoid mechanical damage on the surface of SEM samples, which is essential for EBSD.
Products for preparing surfaces by mechanical polishing or for extracting samples from bulk materials.
Selection of cutting edge technologies and equipment for preparing specimens before examination on electron microscopes. Our portfolio includes a full range of products from microtomes and cryo-fracture equipment.
