02 // Vacuum Pressure Tiers
We grade our product by particle density (how many atoms remain in the box) and mean free path (how far a particle travels before it hits another — critical for Phase Flash deposition and beam transport).
Pressure: 1 to 10−3 Torr. Atoms: ~1013 per cm³ (trillions).
Mean Free Path: Micrometers. Atoms still colliding constantly.
Use: Mechanical grip, Vapor-Lock seals, suction systems, basic insulation. Standard rotary and scroll pumps.
Pressure: 10−3 to 10−9 Torr. Atoms: ~109 per cm³ (billions).
Mean Free Path: 10 cm to 100 km. Gas stops flowing like a fluid and starts behaving like individual ballistic particles.
Use: Metallic Sciences arc remelting, crystal growth, basic Phase Flash processes. Requires turbomolecular pumps.
Pressure: 10−9 to 10−12 Torr. Atoms: ~105 per cm³ (hundred thousand).
Mean Free Path: Thousands of kilometers. An atom in this box will travel from London to New York before encountering another atom.
Use: Aetheric Sciences photonic processors, particle accelerators, MBE. Surfaces stay atomically clean for hours. Requires ion pumps + titanium sublimation.
Pressure: < 10−12 Torr. Atoms: < 10,000 per cm³. Residual populations measurable by individual-molecule detection.
Mean Free Path: Exceeds tens of thousands of kilometers. Particles traverse the chamber without collision.
Use: Antimatter storage and quantum state preservation. If one hydrogen atom hits your antimatter, it annihilates. Requires cryogenic cooling + getter walls. Call for quote.
