Frequently Asked Questions
Is the LVEM5 suitable to use as a teaching tool?
|Yes. The system is both functionally versatile, introducing students to the basics of TEM, SEM and STEM and versatile enough to allow for hands-on experience with an electron microscope and results.|

Is the LVEM5 really an electron microscope?
|Yes. The LVEM5 is a Transmission Electron Microscope (TEM) which can be optionally equipped with detectors that add Scanning Electron Microscopy (SEM) and STEM (Scanning Transmission Electron Microscopy).|

What are the distinguishing factors of the LVEM5?
|There are many notable features of the LVEM5 that differentiate it from standard electron microscopes. The benchtop footprint is – by far – the smallest available for TEM or SEM, and the installation requirements are minimal (no cooling water, no special electrical source). The fact that in this small design there can be both TEM, SEM and STEM modes is also a first. In terms of operations, the TEM mode has much higher contrast than standard, higher voltage TEM.|

What is the benefit of the system for life science researchers?
|Aside from the common advantage that all LVEM5 users share – namely a local EM with an affordable initial costs and operating costs – for life scientists, the increased TEM image contrast is very advantageous. Normally, staining would be required with other systems but with the LVEM5 ultra-high contrast is achieved without staining.|

Does one have to acquire all modes, TEM and SEM and STEM?
|No. The LVEM5 is at its core a TEM so TEM alone is the base model. SEM and/or STEM can be optionally added depending on your research goals. For detailed ultrastructure TEM is required and for surface detail a scanning mode should be acquired.|

Who else makes a benchtop TEM?
|Again, no one. The convenience, practicality and affordability of the LVEM5 is unique to the Delong design. We welcome you to search for a competitive alternative, but we’re sure we will see you back here.|

Can you give some examples of specimen types that have been successfully imaged with the LVEM5?
|Practically every sample type that is imaged by classical TEM can be imaged by LVEM, often with better results. Only heavy elements (metals) and those that cannot be thinly sectioned are precluded from imaging by the LVEM5.|

How complicated is the LVEM5 to operate?
|Like all sophisticated, high tech equipment the LVEM5 requires proper training. That being said, the actual operations of the system are intuitive and basic. The user interface allows control of all internal parameters in a simple manner and mechanical adjustments needed for alignment are easily acquired with training and practice. And our after sales support is very responsive so if you have any questions, we will be available to help you out with any questions that you may have.|
