Images showing the resolution that can be attained using this holder in the 3200FS both untilted and at high tilt are located here. ![]() ![]() However, because of the narrow construction of the blade that holds the grid, it is easy to damage (bend) this holder or the copper piece that clamps the grid into place, and users need to be aware that significant damage can be done to the holder. It will be the holder that most users initially learn to load when using the 3200FS. It is one of the easiest of the holders/retainers to use. This holder normally stays with the 3200FS. High Tilt Room Temperature Retainer (EM-21311 HTR): This very narrow, high tilt retainer is capable of ±YY° tilt in the 1400plus. Images showing the resolution that can be attained using this holder in the 3200FS both untilted and at the tilt limits are located here. This holder is normally kept with the 1400plus and is the first specimen holder that people will learn to use when training on the 1400plus starts. This retainer is quite easy to load (an image of the open holder can be found here) and should be used when recording data that does not require extreme tilt. Quick Release Room Temperature Retainer (EM-11610 QR1): This wide retainer is capable of tilting ☒5° in the 1400plus. This holder is normally kept with the 3200FS and we currently try to keep a replica diffraction grating grid (a so called waffle grid, used for magnification calibrations) in this holder at all times. This retainer should be used when recording data that does not require significant tilt. Standard Single Tilt Room Temperature Retainer (EM-21020): This wide retainer is capable of tilting ±XX° in the 1400plus. We currently have the following retainers: ![]() Additional images of this holder are here. The smallest amount of tilt for any of the retainers seems to be ☑5° and tilt ranges of at least ☖0° are possible with some retainers and holders. These specimen holders can be tilted around the x-axis ( i.e., the long axis of the specimen rod) and the amount of tilt is limited only by the size of the gap in the polepiece of either our 1400plus or 3200FS and the width of an individual retainer. Such specimen rods must be used with various JEOL "retainers" (the grid-holding attachement at the end of the rod). We have three identical JEOL specimen rods which are referred to as the "Common Specimen Holder," part EM-21010 (SCSH). However, please do keep in mind that we have established a holder cleaning protocol that must be followed before a holder that has been used in the 1400plus can be used in the 3200FS, and that some of these holders normally live with a particular microscope. Holders Available for the JEOL JEM 1400plusĪlthough all the holders that can be used in the JEOL JEM 1400plus can also at least potentially be used in the JEOL JEM 3200FS, some of the holders described here are essentially reserved for use in the 1400plus (and note that most of the information shown here is duplicated on the 3200FS holder page). ![]()
