A device used to measure piston travel
Software embedded into the instrument's hardware. Sometimes you may receive
firmware upgrades
A measure of polymer's mass flow rate (grams extruded in 10 minutes) using a
particular orifice under specified conditions of temperature and load
A test used to obtain two different flow rates at two different shear stresses. This
may provide insight to the slope of a flow curve.
A measure of the capacity of a polymer molecule to enhance viscosity.
An instrument used to perform ASTM D-1238 testing of molten plastics and
other polymers
Measurement of the amount of extrudate accumulated for a given amount of
time. The test is completely manual and is sometimes called the "cut-n-weigh"
method
This test measures the amount of material extruded over time and a volume
extruded over a distance. A means of measuring travel is employed. In order to
run a method B test, an A/B run MUST be run first to determine the polymer's
melt density.
Measurement of the volume of material that extrudes over time. Can be
conducted only after an A/B experiment is conducted. This is a "no-cuts,"
automated test that is the most convenient for busy laboratories.
Material is forced through an orifice at a specific temperature using a specific
weight. The volume extruded in a 10minute period is an MVI, in cm/10 min.
A component used to measure the amount of time it takes the piston rod to
travel a certain distance.
An optional system allowing the user to automatically raise and lower weights
onto the piston rod. Requires 70psi shop air.
(Resistance Temperature Detector) A component that senses temperature and
changes in temperature.
A device that the optical eye uses to measure distance and time
