Options for Special Requirements
A comprehensive list of optional features provides for the testing of a wide range of materials. These include:
|
|
LCR7000
|
LCR7000 capillary rheometer with load cell, with cleaning and operating tools, and one tungsten carbide orifice.
|
Corrosion-resistant alloy barrel for testing corrosive materials such as PVC
Tungsten carbide dies with a broad range of diameters and L./D ratios provide a wide range of measurement capability
Laser micrometer for accurate measurements of die swell as the extrudate exits the die
|
|
LCR7001
|
LCR7001 capillary rheometer with load cell, barrel-mounted pressure transducer, and long barrel, includes cleaning and operating tools and three tungsten carbide orifices.
|
Corrosion-resistant alloy barrel for testing corrosive materials such as PVC
Tungsten carbide dies with a broad range of diameters and L./D ratios provide a wide range of measurement capability
A melt pressure transducer mounted just above the die, eliminates frictional and barrel pressure effects
Laser micrometer for accurate measurements of die swell as the extrudate exits the die
