Low vibration thermostat

Ultra-low vibration sample chamber

On the air flotation platform, the vibration isolation structure between the refrigerator and the sample chamber is designed to achieve ultra-low vibration of the sample chamber.


Installation base: passive air flotation platform

Minimum temperature: ≤3.0K

Z-axis vibration:<100nm

X/Y axis vibration:<100nm

Parameter Details

In order to meet the needs of users' customized systems, we can provide the following additional upgrade options on the basis of conventional cryogenic systems. You need to specify in advance when placing an order.


01/ Precise temperature control

Through the use of a combination of passive and active temperature control methods, the precise temperature control requirements between 3K and 60K are realized.

HeaterHTR-50
Temperature control range

3K~60K

Optimal temperature control accuracy±0.5mK


02/ Magnetically shielded sample chamber

The shielding cavity is made of special permalloy that maintains high permeability at low temperatures to achieve the magnetic shielding effect on the cavity.
