External Heating Block - It's All About the Flow

As an accessory to DMA HP, the External Heating Block from Anton Paar keeps samples warm throughout the entire density measurement process, also in the filling- and sample tube. A common laboratory heating plate, often already available in the lab, provides the necessary heat.

The DMA HP density meter, which has been specially designed for the measurement of samples with high melting point, manages sample temperatures up to 200°C.

Especially oils and waxes must be measured at temperatures high enough for the materials to remain fluid and not to harden in the supply lines.

The supply lines to the measuring cell are heated to a temperature that allows for hassle-free sample filling. Time-savings are enormous, since dilution and cooling is no longer necessary. And because there are no more complicated conversions but measurements at the desired sample temperature instead, density determinations with DMA HP and the External Heating Block combined provide more accurate measuring results than other methods.

As opposed to the work-extensive pycnometer method or time-extensive dilution and conversion, DMA HP combined with the External Heating Block guarantees accurate, fast measurement and cleaning.
