SEM-EDX GUIDE FOR BUYERS
Chapter 1 - Price Range of the SEM-EDX Tabletop and Compact Devices
Foreword
The gap between light microscopes and traditionally expensive and large Scanning Electron Microscopes (abbreviated "SEM") has long been closed by a new generation of SEM devices. Latest systems are smaller, faster, more economical and also available in table format. The user-friendly operation allows the use outside of specialized research laboratories.
The key to a successful in-house implementation is the choice of an instrument that best fits your needs. Our guide assists the buyer in choosing with practical advice and technical information.
Tabletop, Compact Device or Large Device
Tabletop or benchtop SEMs save space and can be easily integrated into existing rooms. Compact floor-standing devices require a separate floor area, but offer a larger sample space and more options for future expansion. If there are no spatial restrictions, a tabletop device does not automatically have to be the first choice.

Tabletop SEM & compact stand unit
At the upper end of the performance class are the major research instruments, often equipped with a field emission source, ion beam and special spectroscopic detectors. In order to be able to use such devices adequately, a full-time operator with appropriate qualifications is needed.
Pricing, Automation and Extensibility
The following table gives an overview of the costs in the tabletop device class:
Model | Domestic Equipments | Stage | Mag | EUR Price |
---|---|---|---|---|
Basic Tabletop SEM | BE | XY | 100kx | 60 thousand |
Advanced Tabletop SEM | BE, SE | XY | 200 kx | 85 thousand |
XL Tabletop SEM-EDX | SE, BE, Low Vac, EDX | XY (large chamber) | 100kx | 130 k |
Automated Tabletop SEM-EDX | SE, BE, Low Vac, EDX | XY (large chamber) | 100kx | 160 thousand |
The level of technological development is an underestimated factor, especially in the market for entry-level SEM models. New providers often do not have the know-how of established manufacturers, which means that the devices are less sophisticated. This is particularly noticeable in the level of automation of the electron column alignment. Depending on the manufacturer, the corresponding adjustment is carried out completely manually by the user or fully automatically, which brings with it a considerable difference in user-friendliness.
If you are considering expanding the analytical capabilities at a later date, you should take this into account when purchasing. Many manufacturers offer a wide range of expansion options (e.g. detectors, sample holders, preparation modules, etc.).
