Notes
* Lifetime for Revco units can vary between 8-14 years
** The subtotal for the Stirling does not include the Medical Device Surcharge or the shipping rate
*** Average space cost can vary between $400-$600 per sqft in large modern lab buildings
**** Energy savings mode for the Stirling unit is when set at -70degC, but there is a separate mode for the Revco
units in which the range of temp is larger
