![]() Each cassette holds up to 12 grids, which must be “clipped” with supporting rings to increase rigidity and facilitate automated handling.at least two of Thermo Fisher Scientific's newer cryo-EM products use an autoloading system, where a capsule is loaded with a cassette in a special cassette/capsule loading station. ![]() Cryo-EM instrument manufacturers have been upgrading their sample handling hardware to facilitate loading and measurement of much larger numbers of samples.H01J2237/204- Means for introducing and/or outputting objects.H01J2237/2001- Maintaining constant desired temperature.H01J2237/20- Positioning, supporting, modifying or maintaining the physical state of objects being observed or treated.H01J2237/00- Discharge tubes exposing object to beam, e.g.H01J37/185- Means for transferring objects between different enclosures of different pressure or atmosphere.H01J37/18- Vacuum locks Means for obtaining or maintaining the desired pressure within the vessel.G01N23/20033- Sample holders or supports therefor provided with temperature control or heating means.G01N23/20025- Sample holders or supports therefor.characterised by X-ray source, detector or optical system Accessories therefor Preparing specimens therefor G01N23/20008- Constructional details of analysers, e.g.for investigating non-crystalline materials by using reflection of the radiation by the materials for investigating crystal structure by using scattering of the radiation by the materials, e.g. X-rays or neutrons, not covered by groups G01N3/00 – G01N17/00, G01N21/00 or G01N22/00 by using diffraction of the radiation by the materials, e.g. ![]() G01N23/20- Investigating or analysing materials by the use of wave or particle radiation, e.g.G01N23/00- Investigating or analysing materials by the use of wave or particle radiation, e.g.G01N1/42- Low-temperature sample treatment, e.g.G01N1/28- Preparing specimens for investigation including physical details of (bio-)chemical methods covered elsewhere, e.g.G01N1/00- Sampling Preparing specimens for investigation.G01N- INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES.H01J37/20- Means for supporting or positioning the objects or the material Means for adjusting diaphragms or lenses associated with the support. ![]() for the purpose of examination or processing thereof
