Technical specifications

• Brand: Varian
• Reference / model: RAD-21
• Model: Sapphire
• Manufacture date: December 2013

Additional product details

• This unit features a 12° tungsten-rhenium-molybdenum target with dual focal spots (0.6 mm and 1.2 mm), providing the versatility to switch between high-detail extremity imaging and high-power abdominal or chest radiography.
• Manufacturer: Varian Medical Systems (Varex Imaging)
• Tube Type: RAD-21
• Housing
• Anode Heat Capacity: 300 kHU
• Maximum Voltage: 150 kV
• Focal Spots: 0.6 mm (Fine) / 1.2 mm (Large)
• Target Angle: 12°
• Target Material: Tungsten-Rhenium-Molybdenum
• Dual Focal Spot Precision: The 0.6 mm focal spot is ideal for orthopedic work where fine bone detail is required, while the 1.2 mm spot provides the power needed for bariatric or deep-tissue imaging.
• Standard Integration: As a widely used Varian model, the RAD-21 is compatible with a vast array of OEM and third-party X-ray generators and stands, simplifying the replacement process.
• Status: Used – Harvested System Subcomponent.
• Extraction Note: This tube was professionally removed from a decommissioned imaging system. It was handled with care to preserve the integrity of the housing, bellows, and high-voltage receptacles.
• Functional Assessment: Being sold in "As-Removed" condition. While the tube was operational at the time of extraction, it is the buyer’s responsibility to perform a professional vacuum check and "seasoning" (warm-up) procedure per manufacturer protocols prior to clinical use.
• Serial Numbers: Housing: H216053 | Insert: 76783-Y3.
• ✔ Primis "Safe-Arrival" Guarantee We guarantee the tube will arrive without physical damage to the housing or oil leaks. Due to the sensitive nature of vacuum-sealed imaging components, the buyer is responsible for verifying internal gas/vacuum integrity upon installation by a qualified physicist or biomeds.
