ExactaCoat Inert

ExactaCoat™ Inert Glovebox Coating System

Ultrasonic Thin-Film Coating in an Oxygen- and Moisture-Controlled Glovebox

Many advanced materials can’t be coated in ambient air; even trace oxygen or moisture can alter material properties or prevent thin-film deposition from working at all.

The ExactaCoat™ Inert combines Sono-Tek’s ExactaCoat laboratory coating platform with a fully integrated inert atmosphere glovebox, producing uniform thin-film coatings in oxygen- and moisture-controlled environments below 1 ppm. It’s the glovebox variant of the ExactaCoat platform, built specifically for materials that the standard open-air ExactaCoat can’t process.

Designed for research laboratories, universities, and advanced materials development, the ExactaCoat Inert delivers the same programmable ultrasonic spray coating control as the standard ExactaCoat, inside a controlled atmosphere.

Typical research applications include semiconductor materials, lithium-ion and solid-state battery components, advanced packaging, perovskite solar cells, organic photovoltaics, OLED displays, organic electronics, and other oxygen-sensitive nanomaterial coatings.

With more than 1,000 Sono-Tek coating systems installed at universities and research institutions worldwide, the ExactaCoat platform is an established standard for laboratory thin-film process development.

Built for Oxygen- and Moisture-Sensitive Research

Unlike the standard ExactaCoat, the Inert version operates inside a fully enclosed stainless steel glovebox that maintains oxygen and moisture concentrations below 1 ppm.

The system continuously recirculates and purifies the inert atmosphere while monitoring oxygen and moisture levels in real time. Automatic regeneration, pressure control, and dual antechambers let researchers load samples and materials without disrupting the controlled environment.

Compatible with nitrogen, argon, or helium atmospheres, the ExactaCoat Inert enables reliable processing of air-sensitive materials that can’t be coated under normal lab conditions.

Ultrasonic Atomization Inside a Controlled Atmosphere

At the core of the ExactaCoat Inert is Sono-Tek’s ultrasonic spray nozzle, producing micron-sized droplets that create uniform thin films with minimal overspray. Unlike pressure spray systems, ultrasonic atomization is gentle and highly controllable — reducing material waste while improving coating consistency, even inside a sealed glovebox environment.

Researchers can precisely control:

• Film thickness
• Spray width
• Flow rate
• Deposition rate and deposition rate
• Motion path
• Coating uniformity

The programmable three-axis servo motion platform provides micron-level positioning accuracy, giving repeatable results from early research through pilot-scale development.

Key Features:

• Fully integrated inert atmosphere glovebox with <1 ppm oxygen and moisture
• Programmable XYZ coating platform
• Windows® software with recipe storage and process control
• Continuous oxygen and moisture monitoring
• Automatic chamber regeneration and pressure control
• Dual antechambers for sample transfer without breaking atmosphere
• Stainless steel glovebox construction
• Brushless servo-driven motion system
• Compatible with nitrogen, argon, or helium environments
• Non-clogging ultrasonic spray technology
• Uniform thin-film deposition with minimal overspray
• Configurable with multiple ultrasonic nozzle designs

The ExactaCoat Inert can be configured with Sono-Tek’s complete family of ultrasonic spray nozzles, allowing researchers to optimize coating performance for virtually any application.
