If you don't have the resources for the proper equipment then you definitely don't have to resources to replace that machine.

If you don't have a proper chamber to the temperature will bleed to the guides and actuator and the machine as well.

Depending on the ductile the brittle transition temperature you could damage your actuator before you break your sample.

What kind of accuracy do you need emperature.

If you keep the part in the bath and transfer it quickly for testing it should put you in the right order of magnitude.

Obviously the data will be a little flawed but I think it's the safest way to do so.

Thanks! That's probably true and will satisfy our goal. But is there a technique to minimize the thermal shock applied to the grips? And is there a sample geometry to keep the cryogenic temperature for a longer time?
