Assimilation Traps

A Rechargeable In-Line Trap to Help

Prevent Backstreaming

T

he Assimilation Traps are similar to our Coaxial Foreline

Traps in that they are used between the rough vacuum

pump and the diffusion (or turbo) pump to prevent

backstreaming of oil into the diffusion pump. In addition, these traps

prevent particulate matter from entering the vacuum pump.

Assimilation Traps have the added feature of a replaceable

filtering element. This allows easy replacement once it becomes

contaminated, clogged, or corroded. A variety of different filtering

mediums are available for specific applications described below.

The quick clamp seal incorporates a viton gasket to provide a good

vacuum seal. In addition to the elements listed, the user could incor-

porate his own medium into the assimilation trap for special appli-

cations. For example, if a lot of acidic compounds were to be

pumped by the vacuum pump, NaOH or other basic compounds

could be used in the trap to neutralize acids, and

aluminum oxide filtering material could be used for high efficiency fil-

tering. For applications such as lyophilizing

(freeze drying), water

trapping media such as Drierite® could be used. Activated carbon

could also be used to trap organic molecules and keep them from

contaminating the vacuum pump oil.

Features:

•

Replaceable element in a wide variety

of materials

•

Prevents backstreaming

•

Wide variety of connections

Assimilation Trap Elements

The standard element is coarse OFHC (oxygen free hard

copper). Optional filtering elements are available as described

below.

Coarse grade OFHC copper elements are standard. They

provide a large surface area for condensing oil vapors. The pure

copper surface attracts hydrocarbons due to its high affinity for that

type of compound. Coarse grade stainless steel is for applications

where a copper element is not desirable due to the reactivity of cop-

per with certain chemicals.

Trapping elements should be replaced every 6 months.
