Select Master Bond adhesive systems have played a vital role in the assembly of cryostat cooling devices. These specially formulated compositions possess excellent temperature stability and enable samples within the cryostats to sustain extremely low cryogenic temperatures using common cooling medium such as liquid nitrogen (LN2), liquid helium (LHe). Employed in multiple aerospace, medical, research, science applications including superconduction, cooling and infrared devices, low temperature physics, sensitive measurments are readily achieved with state of the art equipment.

Master Bond compounds are job proven systems and have been used for closed-cycle cryostats, continuous-flow cryostats, bath cryostats and multi-stage cryostats. These vessels are typically assembled with non-magnetic materials and utilize copper, aluminum for thermal shielding. They are carefully engineered to prevent leaks, maintain vacuum integrity and meet customer handling interface needs with lifting bugs, mounting flanges. Thermocouple gauges assure vacuums are properly monitored.

Superconducting magnet medical devices such as magnetic resonance imaging (MRI) are used by doctors/health care professionals to scan a wide variety of medical conditions. This is done by radio waves and a magnetic field. Through the use of wires inside the machine that must be around zero degrees, liquid helium must continuously soak the wires. Biological microtome is another important example of how cryostats are vital for microscopic examination of uniform sections of tissue. Cryostat cut frozen sections can result in speedy, accurate diagnosis in sections as thin as one micrometer. Only a short time period is needed for relevant clinical information shortening significantly tissue biopsy preparation. This has resulted in identifying the patient's systems and prompt actions to treat the conditions.
