I believe pic solutions would sell you one, there was one in another lab in Colorado. I believe they returned it though. They key was the Lewa liquid pump, although it was too low in flow. (One flow formula for co2 is minimum 1kg/min flow per liter of vessel size) Those pump parameters work well to pull multiple fractions in a timely manner. The downside is that a liquid pump will need a diaphragm pump to return the vapor co2 through condensor and back to liquid pump supply. Or just run open like most co2 systems were designed for and eliminate worrying about supplying btu’s to condense which is the achilles heel of many systems. The sfc system is the one to covet or one scaled larger. I don’t believe evolab has an exclusivity on the sfc gear.
