Foreline
Traps
These rechargeable in-line traps effectively block oil back-streaming from mechanical pumps. Any mechanically pumped system, even one with a turbo pump, should have a foreline traps. The trap is placed in the foreline between the roughing pump and the diffusion or turbo pump. It uses a disposable, oxygen- free copper maze absorbent which requires no liquid nitrogen and will not hold water. Typically the maze is replaced every 1-2 years. The seamless body is available in aluminum.
Features:
- A quick change clamp for replacement of maze
- A viton O ring end cap
- A recessed screen
- Available in five pipe diameters
Replacement elements (Copper Maze) also available.
* Available in stainless steel upon special request.

Vacuum
Monitor
This vacuum monitor allows you to monitor the vacuum level in the foreline between the roughing pump and the diffusion (or turbo) pump. A high value would indicate a leak in the system or possibly an inefficient roughing pump. Comprised of a thermocouple gauge control module and cable. The unit can mount directly to the Foreline Trap via a thermocouple (TC) port supplied at no charge when ordered with a Foreline Trap. The 3-station version of the Vacuum Monitor allows the vacuum levels of several pumps to be measured.

Tungsten
Metal Wire and Boat
Properties of Tungsten:
Tungsten has the highest melting point and lowest vapor pressure of all metals, and at the temperatures over 1650°C has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids.
Tungsten is the most useful material used in vacuum evaporation technique, due to its special properties and cost factor.
