CS204-FMX-19OP
The Omniplex: CS204-FMX-19OP is a top loading optical cryostat with the ARS manufactured DE-204 for high cooling power and fast cooldown. The helium vapor is particularly useful for cooling samples that do not conduct heat well.
The ARS Omniplex systems feature large optical access, quick sample change, fast initial cooldown (90 minutes to 20 K), and adjustable radiation baffles to optimize sample temperatures.
The Omniplex: CS204-FMX-19OP comes with 4 window ports and with warm and cold windows. A variety of options allow this system to be customized to fit the researcher's needs, including custom tail pieces, load-lock gate valves and low vibration interfaces.
The sample stick can use any of the standard ARS sample holders, as well as receive a second set of temperature control instrumentation for fine tuning of the sample temperature.
