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.
