Fourth State

We offer Ozone and NOx gas generators, based on patented Air Plasma (fourth state of matter) technology.

These gases have antimicrobial, bioactive and chemical effects, applicable to many industries.

Before Fourth State, we designed plasma thrusters for space propulsion. Inspired by research in plasma medicine and agriculture, but dissatisfied with existing approaches, we realised we could apply our skills to challenges on Earth.

Our mission is to make the benefits of these Reactive Oxygen and Nitrogen Species (RONS) accessible – anywhere, anytime – with just air and electricity.

Compared to other sources of RONS (chemicals, compressed gas cylinders and other plasma technologies), our in-situ generators are:

• Easy: user-friendly, highly-automated, modular, portable
• Effective: precise, robust, broad-capability, value-for-money
• Safe: risk-managed, rigorously-tested, shielded, interlocked
• Sustainable: long-life, serviceable, decentralised, low-material

We’re here for businesses and researchers wanting to:

• Know: use RONS precisely for research or chemistry
• Clean: combat AMR pathogens, biofilms and viruses
• Treat: improve patient health outcomes and wellbeing
• Grow: increase process yields, quality and efficiency

and customers can get started today with:

• Modular OEM components: ModuNOx™
• Fully-integrated laboratory equipment: NOxLab™

Our technology was developed and validated in the UK (with leading universities & grant funders), is manufactured in the UK to ISO9001 (BSI-audited), and has been independently tested by the National Physical Laboratory (calibration services available on request).
