A modular high-pressure cell

The BETSA® Membrane – Diamond Anvil Cell (M-DAC) is a modular high-pressure cell, available in a wide range of configurations to match your experiment — from low, room and high temperature to a large temperature range, and from low to ultra-high pressure.

It is suited to a broad range of techniques: visible spectroscopy, single-crystal and powder X-ray diffraction, Raman and infrared, radial diffraction, Brillouin and X-ray spectroscopy, laser heating and amagnetic experiments.

Composition & materials

Composed of: standard anvils, conical anvils, diamond window, cover, piston, cylinder, dowels, rockers, seats, external adjustment (bridles) and internal adjustment (adjustment screws).

DAC body material: Inconel, Inconel high-temperature, beryllium copper (CuBe2).

Screws and other parts: hardened steel, steel, brass, beryllium copper (CuBe2), Inconel high-temperature, stainless steel.

Seats and rocker: Inconel, Inconel high-temperature, beryllium copper (CuBe2), tungsten carbide (WC), titanium diboride (TiB2, 1200 °C continuous), zirconia (ZrO2).

Membranes & clamping

Designed to receive BETSA® membranes: soldered, soldered HT, with screw, lateral soldered, and cover.

Clamp screw (optional): membrane and/or combined with screw; clamping by manual screw (2 left / 2 right); manual screw (4 right) and/or gearbox screw.

Other features: holes can be drilled for access next to the sample to set up thermocouples or electrical connectors for electrical measurements.
