        Acryo TL-4K top-loading cryocooler

        Acryo TL-4K is a top-loading 4K cryocooler, which can effectively cool low thermal conductivity samples or irregularly shaped samples (powders, liquids, pressure cells, etc.). It allows rapid sample exchange while the cryocooler is in operation. A variety of options are available to meet different experimental requirements or match users' budgets, such as GM cryocoolers or pulse tube cryocoolers with different cooling capacities, lower base temperature, larger sample tube inner diameter, lower vibration, compact tail sections compatible with magnets, optical windows, AC susceptibility inserts, rotation sample rods, vacuum sample rods, and single-shot 1.5K options.
