LVEM 5 Benchtop Low Voltage TEM

The LVEM 5 is a highly versatile and powerful imaging system in an extremely compact package and is the only benchtop TEM currently available. Depending on the configuration it can alternate between TEM, SEM, STEM and ED modes without needing to realign the column or adjust the sample. This versatility combined with small form factor allow you to have your imaging exactly where you need it for maximum efficiency.

The miniturised design and ease-of-use of Delong’s benchtop 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.

Multiple EM Modes in the Same Instrument

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)

While the low voltage design enables surface and transmission imaging i.e. TEM and SEM/STEM on the same instrument on the same region of interest. Furthermore, the lower accelerating voltage provides higher contrast in low Z samples.

Life Science Benefits from Low Voltage

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

Low Cost of Ownership

With low establishment costs and virtually no preventative maintenance and servicing needs, the LVEM 5 is extremely cheap to maintain. In fact, the purchase of one of these systems can be cheaper than ongoing maintenance of older instruments.

Ideal for particulate materials

Can save time by using this as a pre-screening instrument before sending to HR-TEM or core imaging facilities
