Reliable Imaging Performance for Clinical Radiography
The Varian RAD-21 Sapphire Imaging Tube is a premium replacement X-ray tube engineered to deliver high-quality diagnostic imaging in general radiography and radiographic suite applications. Designed for heavy-use environments, this rotating anode tube features a dual focal spot configuration — typically 0.6 mm and 1.2 mm — that enables both fine detail visualization and robust, high-throughput imaging workflows. Its tungsten-rhenium-molybdenum target with a 12° angle enhances image quality while supporting efficient heat handling and long service life.

Optimized for High-Volume Rad Rooms
Built to operate reliably up to 150 kV, the RAD-21 Sapphire tube is suited for a range of radiographic exams, from chest and extremity studies to fluoroscopic spot-film imaging. Its high thermal capacity of approximately 300 kHU (~212 kJ) lets it withstand frequent exposures, making it ideal for busy hospital imaging departments, outpatient clinics, and high-demand radiology suites. As a direct replacement for GE Proteus XR/A rad room systems, this tube supports sustained performance and consistent imaging output.

Trusted OEM Replacement for Long-Term Clinical Use
Whether you’re updating diagnostic equipment or servicing an existing GE Proteus XR/A radiography suite, the Varian RAD-21 Sapphire Imaging Tube offers durable construction and dependable performance backed by industry-standard design. Its compatibility with high-frequency generators and rotating anode technology ensures that facilities can maintain uptime and image clarity without compromise. A popular choice among biomedical engineers and imaging technicians, this tube supports smooth integration into existing workflows and helps clinicians deliver reliable patient care.
