Micro-Tec vacuum pick-up tools
Micro-Tec vacuum pick-up tools
Introduction
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 vacuum generated in the vacuum pick-up tool
- the material surface
- the size of the pick -up cup; see lifting capacity table.
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:
- Micro-Tec ESD safe mini vacuum pick-up tool with a bulb type vacuum pump with 15 gauge straight and 45 degrees needles and 4 / 6 / 9.5mm rubber vacuum cups
- Micro-Tec ESD safe heavy duty vacuum pick-up pen with a high performance piston type vacuum pump with 16 gauge straight and 45 degrees needles and 4 / 6 / 9.5mm rubber vacuum cup
- Micro-Tec B126 ESD safe battery operated vacuum pen with built-in pump with straight / bent 16 gauge needles and 4 / 6 / 10 mm rubber vacuum cups and 2 sets of straight / bent fine needles (30 and 27 gauge) for TEM grid handling. The EM-Tec B126 vacuum pen with the built-in battery operated micro vacuum pump allows for precise handling of parts and TEM grids. It is light-weight and not restricted by a vacuum hose. Equipped with the 30 or 27 gauge fine needles it is also called vacuum tweezers. It operates on a standard 1.5V type AAA battery.
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.
