Bad samples are probably the most avoidable source of error in the testing environment. Inconsistent sample volume and shape from test to test can introduce unnecessary variation to your results. That’s because torque is influenced by how close or how far apart the dies are – variations in volume become variations in the data. Alpha’s industry-proven, Constant Volume sample cutters offer two simple solutions to ensure identical samples – one for rheometers, one for Mooney Viscometers. Precise, accurate sample preparation means your data is more reliable. And that increases your ability to set tighter specifications and deliver superior final products.

Alpha’s Sample Cutter
Produces a constant volume rubber sample in seconds. Constant-volume samples are ideal for MDR, RPA and MV instruments where repeatability of rheometer and viscometer testing is essential. With two sample cutter options to choose from, samples fit perfectly in the corresponding sample trays.
Dual-Action Pneumatically operated Sample Press
Obtain rubber samples in seconds.
Compact Size
Ideal for efficient use of bench space and instrument placement.
Dual Hand-Safety Touch Switches
Utilizing optical sensors, two hands are required to activate the machine. This increases operator safety and makes a shield guard unnecessary.
