Standard systems are offered with
inserts that offer temperatures to less than 10 mK, with cooling powers in
excess of 500 µWatts at 100 mK, and are supplied with thermometry at the 1 K
condensing pot, at the still and at the mixing chamber. Please refer to the
ultra low temperature brochure or to our web site (http://www.janis.com/p-dr.html).
These are supplied with a complete gas handling system with precisely
optimized He-3/He-4 mixture. Superconducting magnets with special cancellation
coils that drop the field in the region of the mixing chambers, as well as
carefully designed sample holders that practically eliminate eddy current
heating, are included as part of the standard systems. Both high field magnets
and split pair solenoids are available and special windows for specific types
of electromagnetic radiation are included as required.
