Osmomat 090 The cell unit OSMOMAT® 090 includes the cell thermostat with osmotic cell and pressure transducer, the precision amplifier with integral digital zero adjustment and auto zero and the electronics for temperature control of the cell including power supply as well.
The GONOTEC membrane osmometer OSMOMAT® 090 consists of an osmotic cell, which is located in a cell thermostat. The osmotic cell is divided into two sections by a semi-permeable membrane. In the lower, hermetically sealed half, which is filled with pure solvent, a precision pressure metering system is installed. The upper cell half, positioned above the semipermeable membrane, is designed as a meander- shaped channel system with a large surface. A funnel tube and a discharge enable rinsing and filling of the cell with solvent resp. polymer solution. Due to the osmotic pressure difference between solvent and solution, a vacuum, which is representative for the concentration of the osmotic actively soluted particles, is generated in the lower cell half.
The cell units OSMOMAT® 090 is only working with a control unit SA or B.
