OFITE 4-Unit HTHP Filter Press, 175 mL

Product Description


The new 4-Unit HTHP Filter Press from OFITE is ideal for high-volume laboratory testing. It accommodates four 175-mL HTHP filter press cells.

Each cell has a separate electronic temperature controller and two separate pressure regulators (drive pressure and back pressure). This allows each cell to be heated and pressurized independently, while still sharing a single pressure source.

A variety of test cells are available for drilling mud or cement.
