Acryo TL-1.5K top-loading cryocooler

Acryo TL-1.5 K is a high-efficiency top-loading 1.5K cryocooler featuring simple operation, rapid cooling, high cooling capacity and lower base temperature. When replacing samples, there is no need to heat the entire refrigerator to room temperature. The sample can be quickly replaced by sample rod. It can not only quickly cool conventional solid film samples, but also effectively cool low thermal conductivity samples or irregularly shaped samples (powders, liquids, diamond anvil cell, etc.). It is also the first choice for rapid screening of quantum device samples.

Acryo TL-1.5K have a variety of options, such as choosing GM or pulse tube refrigerator with different cooling capacities, lower temperatures, larger inner diameter sample tubes, lower vibrations, compatibility with superconducting magnets, optical windows, optical sample rods, AC magnetization inserts, rotation sample rods, vacuum type sample rods, He-3 insert and dilution refrigerator inserts, etc.
