Cryo to RT

A helium pressure varying from 0 to 200 bars applies onto a membrane that is in contact with the MDAC piston and will transmit it forces up to 10 kN.

A micro-valve attached to the membrane allows to disconnect the cell from its pressure controller while maintaining the pressure in the membrane.

Cryogenic Gas Loading System

This equipment makes it easy to load cryogenic gases for all of your experiments in quasi-hydrostatic conditions.

It can handle any gas except H2, He and Ne. It suits any type of DAC. It includes a safety valve to secure the loading.

Overview:

The Cryogenic Gas Loading System is composed of a thin stainless steel tank in order to ease the heat transfer from the liquid N2 towards the gas that has to be liquefied.

A Ø65mm laminated glass window allows to easily observe the inside of the device.

A tool for measuring your gasket thickness

MEJ01 Other

The MEJ01 was designed to ease the measurement of

the indented gaskets thicknesses.

There is no risk of deforming the gaskets with the steel points.

Mechanical features:

- Resolution: 0,001 mm - 0.00005”

- Mechanical aperture 6.35mm - 1/4”

- XY setting of the lower point.

- Interchangeable conical points.

- Conical point tip size: Ø 0.50 mm

- External sizes:

W= 65mm.

D=120mm.

H=190mm.

External Heating System

The EHS is used to work at high temperature.

A ring around the MDAC heat all the parts to apply an homogeneous temperature at the sample.

The EHS allow to control and measure the temperature with two sensors.

Features:

-Power: 2300 W

-Voltage: 110-230 Vac 50 Hz

-Maximum temperature: 650-700 °C

Gluing and aligment machine

GAM Features Other

The Gluing & Alignment Machine [GAM] makes it easier the gluing of your diamonds on seats, on rockers and even on drilled diamonds.

This machine can also measure the thickness of indented gaskets; control the MDAC alignment and the loading quality. It is made on the same mechanical structure than our EDM.

High accuracy in centering and very easy operation makes the GAM the best tool to prepare your high pressure experiments.

Features

-Centring accuracy : < 5µm.

-Lighting: retro light using an ultra-bright LED.

-Centering microscope*

-Observation microscope*

-Size: 19 cm wide., 33 cm deep., 42 cm high.

Various additional options allow

- Maintain your DAC to align your diamonds.

-Add a mini resistive furnace to accelerate the glue

polymerization.

-Measure your indented gasket thickness.

-Load samples and ruby in your DAC.

Example of use: diamond gluing

The [GAM] operation is similar to that of the [MH20M] EDM:

1- Drive both the holding rod and the microscope to the reference point using the rotary head, and the [GL100] XY stage.

2- Put the diamond in place and align it using the second XY stage while looking through the centering microscope.

3- Rotate again the head by 90° to place the holding rod on the culet center.

4- Move up the Z stage to press down the diamond, and glue it.

Other characteristics

The [GAM] positioning block can accept parts that

are up to 20mm in height and 30mm in diameter .

The positioning is highly reproducible and can be

adapted to receive parts of any other DAC type .
