A Bomb Calorimeter is a type of constant-volume calorimeter used in measuring the heat of combustion of a particular reaction. Bomb Calorimeter is used to determine the Calorific Value of Coal and other kinds of solid and liquid fuels.

Constructed in compliance with ASTM D-3402 (similar model available to conform to ISO 556), the coke drum tumbler provides the means for determining the relative measure of the resistance of coke to degradation by impact and abrasion.

To determine the CRI/CSR of Coke. Complies with ASTM D5341. Advanced designed Coke Reactivity Applied Test System in conjunction with the Coke Strength Tumbler Test procedure provide a high quality, precision system for determining CRI and CSR.

Used for the determination of the Free Swelling Index of coal by the electric furnace method as designated by ASTM Standard D-720. The Free Swelling Index test is a rapid, small-scale, empirical method for measuring the free-swelling properties of coal.

The Preiser Scientific Ash Fusion System is designed to determine ash cone deformation temperatures in coal and coke ash per ASTM Standard D-1857 and ISO Standard 540 (CO/CO2 reducing atmosphere option). Single and Dual Furnace options availiable. The analysis software allows the user to manually review and generate reports of completed tests.

Preiser Dilatometer series of test instruments is used to determine expansion and contraction characteristics of coal. The fully automatic system is designed around ASTM D-5515 and ISO Standards 349 and 23873 for the Audibert-Arnu method of analysis. Dilatometer and Plastometer Expansion Kits allow the basic Dilatometer to become a multi instrument.

Preiser Scientific’s Grindability Tester is a compact precision built instrument designed specifically for the determination of the relative “hardness” or abrasive potential of coal. Unit is constructed in strict accordance with ASTM Designation D-409 and conforms to procedures proposed by ISO for the determination of the HGI of coal and coke.

The Plastometer series of test instruments, used for the determination of plastic properties of coal by the Gieseler constant-torque method. It is designed to meet the ASTM Standard D-2639 and ISO 10329, providing critical data necessary for the thorough analyses of coking coals. Dilatometer and Plastometer Expansion Kits allow the basic Plastometer to become a multi instrument.

prepASH the Brand name of the TGA from Precisa, combining high performance, ease of operation, precision, and integrity of measurement for efficient use of time and accuracy/traceability in all measurements. Combining furnace, high precision balance, and automation, the prepASH Series enables a huge reduction in workload through the simultaneous analysis of moisture, ash, and volatiles content for up to 29 samples.
