OfiTE MB HTHP Instruction Manual Download Page 3

The OFITE Model MB HTHP Filter Press is designed to test drilling fluids
and cement under elevated temperatures and pressures.  This simulates
various downhole conditions and provides a reliable method for determin-
ing the effectiveness of the material being tested.  The complete assembly
consists of a controlled pressure source, regulators, a high pressure cell, a
system for heating the cell, a pressurized collection cell able to maintain
proper back pressure in order to prevent flashing or evaporation of the fil-
trate, and a suitable stand.
