A LVEM5 multi-modal benchtop electron microscope will soon be installed at the Syracuse Biomaterials Institute at Syracuse University. The LVEM5, capable of imaging in TEM SEM and STEM modes will be used in the research and development of new and exciting biomaterials. Additionally, the group hopes to take advantage of the low voltage imaging capabilities of the tool.
A LVEM5 electron microscope will soon be installed at Pacific Northwest National Laboratory (PNNL), Chemical & Materials Sciences Department. PNNL is one of the U.S. Department of Energy’s (DOE’s) ten national laboratories, managed by DOE’s Office of Science
Delong America is pleased to announce that we will have the LVEM5 benchtop electron microscope on display at booth 553 at the Microscopy and Microanalysis 2010 conference in the beautiful city of Portland, Oregon.
The LVEM5 is the only multi-modal desktop EM on the market. It is able to operate in transmission modes as a TEM and in scanning modes as a SEM or STEM. Users are able to obtain all three types of information from the same sample and even the same area of interest. The LVEM5 is also capable of preforming electron diffraction.
The LVEM5 is capable of 2nm resolution in TEM mode and 3nm resolution in SEM mode, so you can see even your smallest of particles
The LVEM5 benefits from a 5kv electron source that means that you can visualize light weight materials such as polymers or biological tissues without the need for heavy metal stains. This is a huge advantage for users who want to get a greater understanding of their materials, and not their stain.
Please feel free to come by and schedule a demo to see this unique instrument for yourself. We are looking forward to meeting with you at the conference.

A LVEM5 multi-modal benchtop electron microscope will soon be installed at the University of Texas of the Permian Basin. The instrument will be shared among several science departments and used for both high-level research and education.
Led by Dr. Emilien Pelletier, the Institut des Sciences de la Mer de Rimouski at the Université du Québec à Rimouski has obtained an LVEM5 benchtop electron microscope to help them study the short-term and long-term effects of nano-materials on the marine environment.
Dr. Pelletier is the Canada Research Chair in Marine Ecotoxicology. The overall objective of the chair is to understand the impact of natural and anthropogenic stresses on the short-and long-term high-latitude coastal ecosystems to contribute to the conservation, protection and sustainable development of cold coastal marine resources.
One of the key focuses of the lab is to study nanotoxicology as it applies to cold coastal environments. This is an emerging discipline that incorporates studies on the environmental fate and toxic effects of nano-materials on human and marine species such as phytoplankton, bivalves and echinoderms.
Currently the researchers are using the LVEM5 in TEM, SEM and STEM modes to examine marine animals that have been exposed to various nano-materials to better understand how these materials are being absorbed and incorporated into their shells.

Undergraduate biology students at Lehigh University are using the LVEM5 to evaluate bacteriophages obtained from local soil samples. Starting with a tube of dirt collected from a location of their choice, each student underwent the process of isolating and purifying their bacteriophages from plaques on bacterial lawns. Plaques were selected and purified by repeated plating and observation.

We have found that the LVEM can provide high contrast images of a wide variety of samples, including dendrimers
There is a rather informative entry on Wikipedia (Click Here) detailing the Low Voltage Electron Microscopy (LVEM) technique. The entry goes through the advantages and limitations of the technique. The most notable advantages of LVEM are increased contrast, the elimination of the heavy metal staining procedure, and the ability to have TEM, SEM and STEM in the same instrument. We are proud to say that the LVEM5 is currently the only Low Voltage Electron Microscope available commercially today.
