 LIQUID HELIUM RESEARCH DEWARS
A liquid helium
reservoir dewar with surrounding liquid nitrogen shield and variable
temperature insert defines the most popular research dewar. The sample is fast change, top
loading and can be manipulated while operating. Typical operating
temperature range is between 1.4K and 325K.
High efficiency CN-E models offer very low liquid helium loss rates.
Typical optical configurations offer miniscule, 0.025 - 0.040 l/hr,
liquid helium loss rates! |
SUPERCONDUCTING MAGNET SYSTEMS
Most popular are split coil optical systems.
The SM6 model leads the industry in efficiency and standard
features, such as large optical solid angle and full length
radiation shielding for the sample tube allowing high temperature
operation with low liquid helium consumption.
Standard solenoids are available with magnetic fields
to 17T, cryogen free or LHe styles. Combining a bucket dewar with a
top loading superconducting magnet and variable temperature insert
is typical and a powerful research tool! |
BUCKET DEWARS
CRYO manufactures both stainless steel and
epoxy-fiberglass styles that are available in a range of sizes and
styles with vapor cooled shields or liquid nitrogen shielding. |
RC102 & RC110 CRYOGENIC WORKSTATIONS
Continuous flow variable temperature sample in vacuum
cryostats. If sample in vacuum, portability, low cost, fast cooldown
and easy for graduate students to operate are desirable features,
the RC102 can do them all. Operating range is 1.4K to 325 with a
1000K extended temperature option. A transfer line with flow control
is supplied. Just stick the line in the storage dewar open the flow
valve and have the sample at approximately 4K in 8 minutes! |
RC152 CRYOGENIC WORKSTATIONS
Continuous flow variable temperature sample in vapor
cryostats. Quick sample change, high power handling and efficient
vapor cooling are just some of the features.
Standard operating temperature is <2K to 325K with
continuous flow. 1.4K temperature is accessed in one shot mode,
i.e., flow off. An
exclusive buffer volume design can provide extended low temperature operation
at 1.4K. The 1.5K option extends the continuous operating
temperature down to 1.5K with a 16cfm pump - a world record low for
continious flow operation!

Operating down to less than 300 mK, these helium 3
systems can be integrated into our cryostats, superconducting magnet
systems or inserted into standard storage (transport) dewars. |
LIQUID NITROGEN RESEARCH
DEWARS
Sample in vacuum pour fill cryostats.
If sample in vacuum, LN2 cooling, portability, lowest cost, fast
cooldown and easy for graduate students to operate are desirable
features, the LN102 g & LN110 can do them all. Operating temperature
range is 65K to 1000K. Our thermal link design simplifies operation
and provides sophisticated specifications. Our unique VP (VariPower)
design allows adjusting the cooling power externally for highest
efficiency and experimental versatility. Refill while holding the
sample setpoint temperature for unlimited 'run' time; no need to
remove the thermal link or crown assembly for filling or emptying!
Sample in exchange gas cryostats offer quick
change top loading samples. Samples are cooled by immersion is
static exchange gas. The liquid nitrogen reservoir surrounds the
central sample tube. Load your samples into this tube filled with
exchange gas and samples will immediately begin cooling. The
exchange gas thermally couples the sample to the liquid nitrogen.
The thermal coupling to the liquid nitrogen is controlled by
adjusting the amount of exchange gas in the sample tube. Ultra high
temperature stability is a characteristic of sample in exchange gas
systems.
Sample in vapor cryostats offer quick
sample change, high power handling and efficient vapor flow cooling.
Liquid nitrogen flows from the reservoir to a vaporizer/heat
exchanger located at the bottom of the sample tube. The LN2 flow
rate is controlled by a needle valve located in the reservoir. The
temperature is adjusted by adding heat to the hi-power heater in the
vaporizer/heat exchanger. |

CLOSED CYCLE CRYOGENIC WORKSTATIONS
CRYOGEN FREE
10K Refrigerators
Using a refrigerator (no cryogens), these systems provide a quick
and easy way to reach low temperature down to 8K. Systems can be
configured with sample in vacuum or top loading sample in exchange
gas.
4K Refrigerators
Using a refrigerator (no cryogens), these systems provide a quick
and easy way to reach low temperature down to below 4K. Systems can
be configured with sample in vacuum with a selectable cooling power
of 0.1W to 1.5W of cooling power at 4.2K! A popular configuration is top loading
sample in exchange gas with an exclusive CRYO option that provides
sample temperatures down to 1.5 K!
3He Insert and 4K Refrigerator
A low vibration pulse tube refrigerator condenses
helium 3. An internal charcoal adsorption pump is used to lower the
vapor pressure above the He, lowering the temperature to
approximately 300 mK!
4K Refrigerator with
conductively cooled superconducting magnet
Available in split coil or standard solenoid designs. One
refrigerator design with sample variable temperature. Other
configurations include Room Temperature Bore or vacuum lock for flow
cryostat. |
