廠牌型號：SFT-10
工作原理：
超臨界流體萃取分離過程是利用超臨界流體的溶解能力與其密度的關係，即利用壓力和溫度對超臨界流體溶解能力的影響而進行的。當氣體處於超臨界狀態時, 成為性質介於液體和氣體之間的單一相態, 具有和液體相近的密度, 粘度雖高於氣體但明顯低於液體, 擴散係數為液體的10～100倍; 因此對物料有較好的滲透性和較強的溶解能力, 能夠將物料中某些成分提取出來。

The SFT-10 is a robust, high precision carbon dioxide pump designed to deliver liquid carbon dioxide at pressures up to 10,000 psi (68.9 MPa). It may be used to deliver both liquid and supercritical CO₂ to new and existing SFE equipment, including SFT’s model 110 SFE. It provides the capability to perform supercritical fluid reaction chemistry (SFR) when used to deliver carbon dioxide to one of SFT’s HPR Series™ high pressure chemical reactors.

The SFT-10 incorporates a high performance, dual piston pump which rapidly produces the pressures required for supercritical fluid and other high pressure applications. Software safeguards protect from accidental over pressurization. The pressure set point is controlled from a push button display located on the control module’s front panel.
