Description

A Rechargeable In-Line Trap to Help Prevent Backstreaming

The 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 incorporate his own medium into the assimilation trap for special applications. 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 filtering. 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.

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 copper with certain chemicals.

Trapping elements should be replaced every 6 months.
