The BRI-160 DAC is a diamond anvil cell of a particular shape, such that it can be adapted to a commercial microscope. Due to the constraints imposed by its use under a microscope, the access to the pressure regulation system is lateral, operated by a long wrench which operates a screw flange in a direct drive pressure system. This transmits the force  to the diamond anvil's seats to generate high pressure on the  sample. A Belleville spring allows a smooth pressure control.

Diamond Anvil Cell technology is nowadays within the reach of even the smallest physics or chemistry laboratory. The simplicity of this device and its affordable price permit any interested scientist to perform measurements at pressures in the 100 GPa range and above. By combining the DAC with different investigation techniques, from the simplest ones, as microscope visual observation, through optical or Infrared spectroscopy, Raman spectroscopy, to synchrotron x-ray scattering, researchers all around the word continues to investigate the changes under pressure of virtually any material. LOTO-eng manufactures a variety of types of DAC, among which, for sure, the one suitable for your purpose. LOTO-eng specialists will help you to identify the most suitable DAC cell, accessories and loading technique to meet your needs, in accordance with your scientific goal and your budget.

The BX9-HT0 DAC is a diamond anvil cell for high temperature studies. In this model the sample pressure is generated by a gas membrane. It is a DAC with a high-performance heating method, using resistive heaters. One heater is mounted on the external body of the DAC and uses 200 W electrical power to reach sample temperatures up to 800 K. It is suggested to operate the cell inside a vacuum chamber, to prevent the oxidation of materials. Alternatively, to prevent oxidation, it is possible to use the cell in inert gas atmosphere.

The cell body material, with low thermal expansion, ensures that it can be used up to temperatures of 800 K. A K-type thermocouple mounted close to diamonds is used to control the temperature. A Rhenium gasket allows stable operation of DAC.

To realize the experiment at high temperature it is necessary to monitor the sample pressure to ensure that it do not drop as temperature ramps up. By a remote pressure device the membrane is under constant He gas pressure during the high temperature experiment, providing a continuous constant load, independent of temperature.

The LOTO-eng Spark Eroder / EDM Machine is the right machine to drill the gasket useful in the DAC cell experiments.
The gasket can be made in different materials such as Steel BeCu Tungsten etc. The gasket support can be customize to accept a large kind of diameters, from 3mm to 18mm.
The SPARK Eroder, an Electro Discharge Machine / EDM, realize a manufacturing process whereby a desired shape (hole) is obtained using electrical discharges (sparks).
Material is removed from the workpiece (gasket) by a series of rapidly recurring current discharges between two electrodes (tip and gasket) separated by a dielectric liquid and subject to an electric voltage.
SPARK Eroder is an automatic machine system designed with innovative concepts and solutions with decisive advantages to use in DAC’s cell utility for a fast and easy drilling of the gasket.
The duration and the efficiency of the ablation process depend on several factors which:
- power and voltage of the current emitted from the tip
- types of materials used for the tip and types of materials for the gasket
- type of dielectric liquid.

The EDM machine uses an owner and interactive software for managing the advance of the tip, controlling the level of discharge.
Thanks to the feedback circuit, the tip is kept upon the gasket, at the right distance, until the whole drilling process is complete.
The user can easily monitor the whole process thanks to a camera placed below the working area that sends the images to the managing software. The software permit to control the tip (tungsten wire from 50-to 500 microns) during the process. Moreover the software control the alignment step that is very important to have success during the gasket preparation.

LOTO-eng developed an Hiper Micro Holes software that  contains many powerful features that make it even easier to and more fun to work with his Spark Eroder Machine. Throughout an easy control panel you can see all the features necessary to control the hole and give potentiality to have success.

The managing software is equipped with a panel for the video output of the camera, so that the operator can control the alignment of the main components, tip and gasket, and visualize the finished work.

The sample can be illuminated, for visual quality inspection, by using a LED source placed on the camera.

How it works?

Hiper Micro Holes Software provides to control cycle to our spark eroder machine designed to dig a precise micro holes to support scientific research in high pressure field.

The EDM machine use an owner and interactive software for managing the advance of the tip, controlling the level of discharge. Thanks to the feedback circuit, the tip is kept upon the gasket, at the right distance, until the whole drilling process is complete. The user can easily monitor the whole process thanks to a camera placed below the working area, that sends the images to the managing software.The software permit to control the tip (tungsten wire from 50-to 400 microns) during the process. Moreover the software control the alignment fase very important to have success during the gasket preparation.
