Vacuum pick-up tools are ideal for picking up lightweight and flat items without touching them by hand or with sharp tools. Delicate items or surfaces won't be scratched. Can be used for coverslips, Si substrates, quartz substrates, small components, parts, samples and TEM grids (if fine needles are used)
The lifting capacity of the vacuum pick-up tools depends on:
The lifting capacity and lifting time both increases when surfaces are flat and smooth (polished). Vacuum pick-up pens will not work on porous surfaces. The components of the vacuum pick-up tools generally are a body to generate vacuum, interchangeable vacuum needle tips and vacuum cups which fit on the needles to increase lifting capacity. The Vacuum pens include a standard male Luer-slip connection on which the interchangeable needles with a blunt tip will fit.
Choice of two Micro-Tec vacuum pick-up tools offered are ESD safe to avoid static discharge:
The fine needles for picking TEM grids are also separately available for use on other vacuum pick op pens. The 30 and 27 gauge needles fine on the 400-500um wide rim which is used on most TEM grids.
