An Introduction to Tribo-Rheometry: Quantifying Friction Tribology complements rheology, providing information on solid-solid interactions that adds insight to the bulk fluid measurements of rheology. Tribology is especially concerned with quantifying the coefficient of friction as a function of sliding speed and load force, under dry or lubricated conditions. This provides useful information about lubrication, wear,…
DetailsAn Introduction to Lifetime Testing by Thermogravimetry Lifetime testing by thermogravimetry (TGA) is a well-established, powerful technique for predicting the long-term aging characteristics of a material in a short experimental time. Multiple techniques and models are presented and compared for lifetime testing, including Modulated TGA™, and a survey of the current ASTM methods and the…
DetailsAn Introduction To High Pressure Rheology High pressure rheology explores phenomena that are not accessible at ambient laboratory conditions. Three of the advantages of using a pressure rheometer cell include a controlled environment for volatile fluids, saturating fluids with soluble constituents, and exploring new phase space using a combination of temperature and pressure.

The AHT Automated Hardness Tester streamlines the measurement of Shore A hardness for cured rubber materials. This fully programmable, automated system measures the hardness of cured rubber materials according to all international standards for Shore A hardness. Each measurement involves the determination of a user-defined number of single point Shore A values. The individual readings, mean and median of this set are reported for each sample.
