Preiser Scientific Inc. products

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).

The Preiser Air Drying Oven provides for the partial drying of coal to bring it to near equilibrium with room temperature before further reduction and division in accordance with ASTM D3302. Oven is often used for drying float/sink samples.

Every stage of the cycle, including water-fill, heating, sterilization, exhaust and drying, are microprocessor-controlled and completely automatic with these electronic models. The digital display continuously shows you temperature, pressure and running time. Four fully adjustable, single-button programs make these sterilizers easy to use and ensure reproducible runs. The handy battery backup ensures that all parameter settings and controls are retained in the event of a power failure.

The market-leading Plastometer is used to determine the fluidity of coking coal.  The Plastometer represents a completely new instrument design.  The Plastometer uses a commercial PC linked to an instrument specific interface and control box. Inter-unit cabling uses reduced size connections and a USB link to the host PC.  The Plastometer head unit and solder pot retains the market leading proven assemblies outfitted with advanced component mounting and other mechanical improvements.  The instrument interface box is equipped to allow single, double, triple or quadruple instrument  operation of a mix of desired Dilatometer and/or Plastometer instrument types which can be specified at time of purchase.  The Plastometer is 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, providing critical data necessary for the  thorough analyses of coking coals.
