The RFM990 is a wide range Peltier temperature controlled refractometer, that has been adapted for use with samples under flow conditions, ensuring that the sample is presented to the prism without entrapped air.

• Navigate applications with two point calibration
• Wide range with choice of four or five decimal place accuracy
• Radio frequency identification (RFID) operator identification and protection

Micro-flowcells are used to transfer volatile or limited volume low viscosity liquids as part of a single or multiple instrument analysis, incorporating an autosampler and pump within the beverage, brewing, flavours, fragrance or essential oil industries.

Macro flowcells are used where sample viscosity limits the use of micro-flowcells or for connection to a pilot plant or smallbatch process line, where a normal process refractometer may not be suitable.

Funnel flowcells may be used where larger volumes of sample are available. These cells negate the need to clean the instrument prism between sample measurements, providing a rapid sample turnaround, such as in Tare Houses of grape growers co-operatives and sugar mill receiving stations.
