M-DAC Types
Membrane – Diamond Anvil Cell — a modular BETSA® range, from low to ultra-high pressure.
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.
