Lab Grown Diamonds

Achieve more consistent, repeatable diamond production with ultra-low flow MFCs

Alicat^® offers high stability and repeatability that gives engineers confidence their recipe was executed exactly as needed. By supplying precise mass flow control for vacuum applications with low flow rates, mixed gases are unnecessary, delivering better diamonds at a lower cost.

Mass flow and pressure controllers for lab grown diamond CVD processes

Control growth rates by creating a precise balance of carbon, hydrogen, and oxygen. Replicate successful recipes across thousands of batches.
Mass flow meters and controllers come with Gas Select to switch between methane, argon, oxygen (or 95 other gases) without any loss of accuracy.
Pressure controllers designed for CVD processes are equipped with a fast-acting proportional control valve which rapidly responds to maintain a stable pressure in chamber.

Applications and use cases

Building CVD diamond machines with flow and pressure regulation

To produce high quality lab-grown diamonds using any CVD method, manufacturers depend on Alicat’s devices to ensure precise gas mixtures of hydrogen, methane, and carrier gases. Learn how combustion-flame assisted, filament-assisted thermal, and plasma-enhanced CVD processes for lab grown diamonds can be enhanced with Alicat mass flow and pressure instruments.

Lab-grown diamond manufacturing with laser-plasma CVD

Plasma-enhanced CVD is the most popular current technique for making lab-grown diamonds. Laser-plasma CVD is a lesser-known subtype existing since the 1990’s which operates at ambient and positive pressures and has higher theoretical diamond growth rates than previous subtypes. Alicat instruments help you design better laser-plasma CVD systems for improved diamond growth.
