Dry-Ice & LN2 Cooled Foreline Traps

Liquid Nitrogen Cold Trap

IS™ cold traps are on the “cold thimble” design. The surface of the cold

thimble containing liquid nitrogen at -187°C, being exposed to the vac-

uum system, rapidly condenses molecules in the vapor phase. This

action provides the trapping effect and cryopumping especially for water vapor

the most common condensable in vacuum systems. Pumping speed for water

vapor at the trapping surface is 95 liters/sec. per sq. inch. The vapor pressure

for water vapor at the cold thimble is reduced to 10

-21

Torr, “theoretical,” produc-

ing a low base vacuum. Other gases found in vacuum processes will be subli-

mated or liquefied at the cold trapping surface. This effect provides a convenient

trapping or collecting mechanism.

Dry-Ice Cooled Foreline Trap

ry-ice and alcohol is all that is needed to cool this cold trap to -100°C, thus trapping most volatile

materials. Holds 3 quarts of dry-ice slurry (dry-ice and alcohol). Holding time is approximately 20 hours depending on vacuum

throughput. The Polycarbonate “Bonnet” flange allows viewing of the trapped (frozen) gas on the cold bucket itself. Defrost and

clean-up is easily accomplished.

For durability and ease of cleaning, the outer body and cold well are electro-

polished ID/OD 304 stainless steel. Viewing ring and lid are clear acrylic plastic.
