Part 8 public contract with a vacuum concentrator with a cold trap
for proteomic work;
One of nitrogen's roles on Earth is to help form a low-temperature layer in the atmosphere that water can't get past, called a cold trap
8226; Plans for polar cold trap
craters, skylights, and peaks investigations
This allows operation without any cold trap
, and thus reduces the total cost of ownership.
homogenizer, washers, vacuum concentrator with a cold trap

Polycold is a leading manufacturer of low- temperature refrigeration systems including water-vapor cryopumps, cryocoolers, cold trap
chillers and gas chillers.
Assembling thousands of ions in a cold trap
produces the equivalent of a one-component plasma -- a collection of charged particles, all with the same mass and charge, embedded in a uniform, oppositely charged background.
This combined data led the science team to conclude the water is not uniformly distributed within the shadowed cold traps
, but rather is in pockets, which may also lie outside the shadowed regions.
Water ice deposits in such cold traps
remain covered by a thin layer of lunar rock.
New is details of hot and cold traps
, runners and trainers - plus other stats.
The sun never reaches these so-called cold traps
, so the water is locked up as ice, explains Spudis.
We find that areas of the crater floors at the poles that are in permanent shadow from the Sun, which are potential cold traps
for water or other volatiles, do not give rise to strong radar echoes like those associated with thick ice deposits in the polar craters on Mercury,' wrote the scientists.
