MultiScan MS 20

The MultiScan MS 20 is the measuring device for the automatic optical stability and aging analysis of liquid dispersions, in particular suspensions and emulsions, and the comprehensive characterisation of time- and temperature-dependent destabilisation mechanisms. It consists of a base unit and up to six connected ScanTowers with temperature-controlled sample chambers. The base unit of the MS 20 features an integrated touch screen that displays status information and can be used to control important base functions. Additionally it is possible to register the studied samples, fast and conveniently, with the built-in or optional handheld barcode scanner. The ScanTowers of the MS 20 can be individually controlled and operated at different temperatures. Electric heating, with liquid counter cooling, allows for measurements in a temperature range of -10 °C to 80 °C.

Features of MultiScan MS 20

• docking ports for six ScanTowers
• built-in barcode scanner for an easy and specific sample registration and documentation
• integrated touch screen for basic operation and control of all connected scan towers
• measurements at temperatures ranging from -10 °C to 80 °C (temperatures below 4 °C require an optional thermal insulation sleeve)
