Capillary extrusion rheometer for test
work
Celsum Technologies has supplied a top-of-the-range ACR 2100 capillary extrusion rheometer to Gammadot Rheology, to allow testing of materials over a wide range of shear rates and temperatures
Celsum Technologies has supplied a top-of-the-range ACR 2100 capillary extrusion rheometer to Gammadot Rheology Testing and Consultancy Services in order to allow testing of materials over a wide range of shear rates and temperatures A capillary extrusion rheometer is a very accurately controlled piston-driven extruder which allows the test material to be expressed at a series of user-defined speeds through precision-engineered orifices or dies, and the pressure generated at each speed is recorded

New strain gauge amplifier housing from Celsum
The new ILE is a compact, robust, precision-engineered, stainless steel EMC-shielded housing that will accept either an InCell analogue strain gauge conditioning amplifier or a DCell digital converter
The characteristic graph or rheogram is useful for predicting processing behaviour and may also be used to deduce information about the specimen chemical and physical nature.
As such, it is an extremely useful tool for analysing and trouble-shooting processing problems.
Said Roy Carter, MD of Celsum , "We are extremely pleased to be able to help Gammadot to enhance their established range of rheological testing services with the addition of this fine instrument.

The ACR 2100 rheometer has a maximum pressure capability of 30,000 psi (2,100 bars) and maximum temperature of 450C, allowing many types of materials to be tested under realistic processing conditions.
As well as shear viscosity, the ACR 2100 may be used to determine extensional viscosity, pressure coefficient of viscosity, no-flow temperature, and other process-relevant parameters".
Mark Edwards, Principal of Gammadot, said "I am delighted that we have a new capillary rheometer to add to our current suite of test equipment.
This will expand the range of contract research and testing services that we can offer our customers, and will greatly assist our development".
Other products from Celsum Technologies include the T2SR Temperature and Time Scanning Rheometer, extrusion dies, MXR2 Extensional Rheometer, the CTPT and CTPVT Workability Testers for fresh cement and concrete, and a wide range of signal conditioning and process control instrumentation, radio modems, accelerometers, pressure and force sensors, dataloggers, and an array of other instruments.
Gammadot offers comprehensive rheological and materials characterisation support to the plastics and rubber industries.
Services cover the application of rheology to quality control, failure analysis and process optimisation issues, to providing accurate materials property data (viscosity, PvT and thermals) for flow simulation software packages such as Moldflow and Sigmasoft 3D.
