Laser Die Swell and Melt Cutter System
Bohlin Instruments (Cirencester, Glos, England), which recently acquired the Rosand rheology product range, has now introduced two new options for the Rosand RH2000 bench-top capillary rheometer, which is available in both twin and single bore configurations.
Together with a new software package, Flowmaster version 8, the laser die swell measurement option allows die swell to be accurately quantified under a wide range of flow conditions, to the same level of accuracy as the floor standing Rosand RH7 capillary system.
The melt cutter option is available for use with or without the laser die swell unit. When used in conjunction with the laser unit, the fully automated melt cutter ensures that the extrudate tension is controlled during the die swell measurement, thus preventing thinning of the melt under tension. Alternatively, without the laser unit, die swell can be quantified directly by the cutter system using an in-built cut interval timer.
Both options are available as a retrofit to existing RH2000 customers.
