3H Tritium Solutions
Tritium is a radioactive isotope of hydrogen. It is used in medical applications (e.g. drug labelling), in luminescent light sources for watches and optics, and as a tracer in geological groundwater monitoring.
Nuclear fusion uses it alongside the other hydrogen isotope, deuterium, for power generation experiments. Tritium is also being explored for battery applications—another promising field of research.
In all these applications, safe and precise handling of tritium gas is essential.

Isotope Handling Equipment
Isotope Handling Equipment
Tritium Valves & Fittings
Specially designed and manufactured tritium valves and components. Based on our long experience in tritium handling.
Tritium Ultra Syringe Pump
Custom-specific syringe pumps with magnetically driven pistons.
Protium/ Deuterium/ Tritium Ultra Syringe Pump
The pump plunger is magnetically driven. The design contains no rotary seals to the environment, resulting in a hermetically sealed system.
The pump housing is vacuum-vented to an external bypass system or scrubber, in case traces of gas pass the plunger seals. This enables closed-loop gas handling.
Multiple syringe pumps can be combined to create a continuous gas flow system, similar to a piston pump. The loading and pressure cycle can be precisely controlled. Real-time process data can be integrated into the pump control to dynamically adjust the gas flow according to actual process conditions.
Benefits of the smolsys Syringe Type Pump System
- Accurate, process-controlled pressurization
- Stable gas flow or pressure (from mbar to bar)
- Slow-moving components
- High temperature stability
- Maximum safety in isotope gas handling
Tritium Custom Equipment
Custom isotope loading vessel, double-walled, with anti-permeation coating.

Requirements Engineering and Process Development
Requirements Engineering and Process Development

By far the most difficult and time-consuming step in a project is identifying and refining the exact requirements.
This is where we support you—guiding you through an in-depth requirements engineering process.
At the end stands a clear picture of exactly how all processes and equipment need to be built and function.
We offer this service for tritium, gas/vacuum handling, and machine building in nuclear and medical applications.

Custom Machine Building and Automation
Custom Machine Building and Automation

In addition to engineering and building automated machines and systems, we can integrate our own off-the-shelf tritium handling products, such as face-sealed all-metal bellows valves and other high-vacuum components, magnetically driven syringe pumps for high-pressure applications, and our new in-line tritium concentration sensor.
Applications:
- Mobile radioisotope handling laboratories
- High-temperature heating
- Automation of hydrogen gas handling systems

Plug & Produce Isotope Labs
Plug & Produce Isotope Labs

The modular labs can be adapted to existing pre- or post-processes without the need to repeat full radiation safety assessments or licensing and risk analyses. If required, access control, personnel monitoring, and air/environment surveillance systems can be added. All system data can be integrated into existing production or security control systems and, if requested, accessed via the cloud (if requested). Fire safety is set to EI 90 by default.
The RMC Method of Tritium handling: Fusion Science and Technology




Our approach
«Plug & Produce» production units – the most efficient and safe way we know.
Working with tritium for decades, we learned that we need something that protects personnel while ensuring that tritium release to the environment is kept to the lowest achievable level. Also, since we work in private industry rather than in a science lab, we knew that processes need to be cost-effective, and machines and automation systems reliable.
We found that the best way to combine these requirements is what we call a «Plug & Produce» pop-up production cell. It consists of a self-contained unit (a specialized lab container) that includes the critical process, machinery, and measurement systems. The unit itself creates a protected environment. Conditions inside are predictable and continuously monitored. Tritium-in-air concentrations (T₂ and HTO), temperature, airflow, air quality, oxygen levels, humidity, and any other parameter need to run a controlled and reliable process.
The benefits of our smolsys Plug & Produce production units:
- Maximum flexibility
- Shortest time to production
- Easy monitoring of safety and performance indicators
- Fast setup as an additional safety zone
- Fully transportable
- Pre-established compliance with regulatory requirements
- Clearly defined and specified interfaces to ist surrounding environment
- Easy adaptation to changing needs—no retrofitting of existing facilities required
- Built-in safety: EI 90 fire protection and advanced ventilation system with 25-fold air exchange per hour

GASEOUS TRITIUM LIGHT SOURCES

GTLS (Gaseous Tritium Light Sources) are widely used in exit signs, watches, and gun sights. smolsys Ltd. offers custom manufacturing of Gaseous Tritium Light Sources (GTLS) according to your specifications. GTLS are manufactured from glass capillaries whose inner walls are coated with a phosphorescent pigment. The capillaries are then pressure-filled with tritium gas. The gas acts as an energy source, providing the power for the lights. GTLS can be manufactured in different colors and brightness levels. They provide self-powered light for decades and withstand harsh environmental conditions. We test and certify GTLS according to MIL-SPEC and ANSI standards.
