Acryo-TL-1.5K Top Loading Refrigerator
The Acryo® TL-1.5K (abbreviated as TL-1.5K) is a high-efficiency top-loading 1.5K refrigerator, featuring simple operation, fast cooling speed, large cooling capacity and lower temperature. By inserting and pulling the sample rod to change the sample, it can not only quickly cool regular solid film samples, but also effectively cool low thermal conductivity samples or irregularly shaped samples (powder, liquid, high-pressure packages, etc.). It is the first choice for rapid screening of quantum bit devices.
The TL-1.5K refrigerator offers a variety of options to meet different experimental requirements or to match the user's budget. Such as the choice of GM or PT cryocooler with different cooling capacity, lower temperature, larger inner diameter sample tubes, lower vibration, compatibility with superconducting magnets, mounting of optical windows, AC magnetic susceptibility insert, rotating sample rod, vacuum type sample rod, He-3 or dilution refrigerator inserts, etc.

TL-1.5K-MB
The TL-1.5K-MB is a low-vibration top-loading 1.5K refrigerator that utilizes a PT or GM cryocooler as the cooling source, and cold head suspension vibration damping mechanism combined with internal flexible thermal connections and rigid supports to reduce the vibration level to less than 100 nm (with a valve body separated PT cryocooler) or less than 1 ㎛ (with a GM cryocooler).
TL-1.5K-NEU
The TL-1.5K-NEU is a top-loading 1.5K refrigerator specifically designed for neutron scattering experiments. The innovative design combined with the self-constant pressure helium cycle system results in faster cooling, with an initial cooling time from room temperature to 1.5K:<270 min, and stability at the lowest temperature is ±2.5mK@1 hour.
The refrigerator is supplied with sample tubes of up to 61 mm internal diameter, which can be easily adapted to the large-size diamond anvil cell. The sample tube is filled with static exchange of helium gas, and the tail section with vanadium window is suitable for neutron scattering experiments. The top of the sample tube is integrated with a programmable motor-driven vertically oriented displacement stage and a rotary stage, which allows up and down movement of the sample rod (travel: 8 cm) and axial rotation, and the system includes two high temperature sample rods that can be operated to 800 K.
