Tabletop Form Factor of the Phenom SEM

There has been a lot of interest in tabletop SEMs due to their ease of use, lower cost, and minimal lab space requirements compared to floor model SEMs.

The Phenom SEM provides significant value considering the small amount of lab space it occupies. It can be setup on standard lab furniture such as a lab bench or portable tabletop, and can even reside on an office desk.

Regardless of whether you have an open tabletop with lots of room beneath, a desktop with drawers on either side of your chair, or a standard lab benchtop, there is plenty of room for the pre-vacuum pump & power supply underneath.

No site surveys are required for tabletop SEMs, either. While full-size SEMs are very susceptible to their environment, tabletop SEMs are mostly immune to vibration or electromagnetic interference, thanks to the miniaturized components.

The power required for the SEM is simply a standard 120V/15A receptacle, providing even more freedom to move the SEM out of a lab and onto a classroom desk, a mobile lab unit, factory floor, or even at a public venue for outreach programs.

The max power consumption is only 250-400 W — similar to a desktop computer.

On a typical tabletop 72” wide by 24” deep (183 x 61 cm) there is ample space for the SEM, computer, keyboard and monitor, with additional room left over for sample mounting.

Tabletops and desktops tend to be of similar size, although many times desktops are deeper and provide even more sample preparation space.
