Small but Powerful
4 Imaging Modes
Ultra-High Contrast
No Staining Required
State-of-the-Art
High Value over Cost
All the buy valium online modes you need in a single electron microscope
Maximize your research scope and budget value with 4 distinct imaging modes, with seamless transition between TEM, STEM, SAED and SEM.
Valium No Prescription
The TEM mode lets you take full advantage of the low acceleration voltage and the associated ultra-high contrast. The image is formed on a YAG screen and can be observed with a binocular or a CCD camera for data storage. View gallery
Selected Area Electron Diffraction (SAED)
Thanks to a seamless transition buy valium from transmission electron microscopy to selected area electron diffraction, you can quickly measure electron diffraction patterns and investigate sample constitution, consistency and purity. View gallery
Scanning Transmission Electron Microscopy (STEM)
When viewing stained samples or when the samples order valium are thicker than that required by TEM, STEM is a good alternative. Enjoy the seamless transition to STEM mode. View gallery
Scanning Electron Microscopy (SEM)
For surface characterization, the built-in backscattered electron detector let you analyze sample topography and composition. View gallery
20x more contrast generic valium than on conventional TEMs
Take pictures with ultra-high contrast thanks to LVEM5’s low voltage electron beam
At low energy, the electron beam interacts more strongly with the sample and provides more contrast. The LVEM5 5 kV electron beam energy was carrefully choosen to obtain buy valium no prescription high electron scattering while keeping low electron absorption.
The contrast is up to twenty times higher than on classical 100 kV TEMs. The LVEM5 lets you observe low atomic number atoms as Carbon, Nitrogen, Oxygen or Phosphore. You can routinely work with unstained biological samples.

Reduce your sample preperation time. Preserve your health from hazardous stains. Observe
real contrasts.
The electron beam interacts more strongly with high atomic number atoms. Sample preparators routinely stain biological and polymer samples with high-atomic number material to get sufficient contrast.
Most of the time, the LVEM5 produces images with sufficiently high contrast to let you work with unstained samples. With the LVEM5, you can simplify your sample preperation protocole, increase your productivity and reduce health hazards related to stain exposure.
Staining may also alter your sample and induce staining artefacts. With the LVEM5, you measure your samples in their natural, inherent state and can guarantee the quality of your measurements.
