LVEM 25E Low Voltage TEM

25kV compact low voltage TEM

The LVEM 25E is a compact low voltage TEM featuring all in one TEM, SEM, STEM, ED and EDS design with performance equivalent to larger systems.

Key Features
- Compact design - Designed to be located where imaging is required
- High resolution - 1.0nm TEM/ 2.0nm SEM / 1.0nm STEM
- Full self-contained - On casters for easy relocation
- Simple installation - No special facilities required - e.g. dedicated room, anti-vibration isolation, power supply or cooling
- 25kV FEG source - High brightness and spatial coherency → high contrast
- Permanent magnet lenses - Simplifies design and reduces size
- 5 in 1 design - 25kV TEM, 10 & 15kV STEM, 15kV SEM, ED & EDS
- Simple to use
- Low cost of ownership

The LVEM 25E’s all-in-one design combines 3 imaging modes (TEM, SEM and STEM) with 2 analytical modes (EDS and ED). With excellent resolving power and high contrast, this system is ideal for imaging at the nanoscle, especially low Z materials thanks to the low voltage. The simple to use intuitive software allows switching between modes and operation by users of any skill level.

The unique design of Delong’s instruments incorporates TEM, SEM and STEM into one instrument. This allows you to glean complimentary data sets from the same sample i.e.:

Topography/elemental surface contrast (SEM)
Amplitude/phase transmission (TEM/STEM)
EDS Data

The compact design and ease-of-use of Delong’s TEMs makes TEM imaging and analysis a real possibility for any lab. The operation is so simple with no need for routine operations such as beam alignment and as such there is no need for an experienced TEM operator. Furthermore, the unique design requires virtually no ongoing maintenance.

Life Sciences Benefit from Low Voltage TEMs

The advantage of low accelerating voltage in life sciences and biology is it eliminates the need for staining so you can visualise proteins and other low Z materials in their natural state i.e. no need for using heavy metals and other toxic agents

Simple Installation and Low Cost of Ownership

With low establishment costs and virtually no preventative maintenance and servicing needs, the LVEM 25E is extremely cheap to maintain.

Meanwhile, one plug installation and special installation requirements mean that the LVEM 25E can be easily installed in virtually any laboratory.
