MBraun QUANTIpure Sublimation Purification System DSU Series
- Sublimation refinement - Everything started with the redefinition of sublimation refinement - The QUANTIpure -
- Sublimation - This term refers to the phenomenon where a substance transitions directly from the solid phase to the gas phase without passing through the liquid phase. Conversely, it also refers to the phenomenon of transitioning from the gas phase to the solid phase, but these are generally referred to as deposition, solidification, or recrystallization. - Conditions for the Occurrence of Sublimation - Common substances exhibit three states: solid, liquid, and gas, which are determined by temperature changes. The boundary temperatures are defined by the "vapor pressure" of each substance. Since the phase change temperature is dictated by vapor pressure, by altering the environmental conditions (reducing pressure), sublimation can occur in many substances without passing through the liquid phase. - Applications of Sublimation and Sublimation Purification Devices - Many compounds have their own specific sublimation and solidification temperatures. By utilizing this temperature difference, it is possible to significantly separate mixed compounds. This phenomenon is applied in sublimation purification devices. Taking advantage of the property that allows direct phase transition from solid to gas, it is widely used for the high purification of "insoluble" substances that are difficult to dissolve in solvents.

basic information
The key technologies of the sublimation purification device are "vacuum (reduced pressure)" and "temperature control." As long as there is a heating sublimation section and a collection harvesting section within the vacuum container, it is necessary and sufficient as a device component, and there is no need for continuity in between. This shift in thinking became the starting point for the QUANTIpure system, which achieves both ultra-high purity and ultra-high yield. By changing the lateral movement of the train sublimation device to vertical movement, the installation floor area is significantly reduced. Since it is sufficient to secure the area of the heating sublimation section and the collection harvesting section as part of the device configuration, the size of the device is inevitably minimized. - It can operate with one-third of the floor area of a horizontal device of the same capacity. - The average annual processing capacity of the device has approximately twice the capability, achieving an effective floor area utilization efficiency of 6 to 7 times. *Both are our calculated values.
