Forensic Audit: structural Purity Intelligence
01
Laminar Stabilization "Pneumatic Capacitor" Authority
Specifically engineered by Applied Materials (AMAT) as a high-integrity flow capacitor for precision gas delivery sticks. This monolithic reservoir acts as a mechanical dampener, smoothing the pressure pulsations from roughing pumps and preventing MFC (Mass Flow Controller) oscillation. Mandatory for maintaining a perfectly laminar gas baseline in sensitive ALD, CVD, or mass spectrometry ion sources where signal jitter is a project-killing risk.
02
UHP Electropolished Internal Matrix Matrix
Internal wetted surfaces feature a factory-applied electropolish finish (Ra < 15 μin). This mirror-grade passivation removes microscopic surface irregularities, dramatically reducing the effective wetted surface area. This architecture facilitates the absolute suppression of moisture adsorption and hydrocarbon outgassing, ensuring that process gases maintain semiconductor-grade purity across the stabilization axis.
03
Forensic Audit: Verified NOS - "Virgin" Sealing State
Confirmed unissued New Old Stock (NOS/NOB) condition from strategic instrumentation reserves. Forensic visual audit under 10x magnification confirms the primary **1/4" Male VCR® (9/16-18 UNF)** sealing bead and the **KF25 (NW25)** quick-flange interface are verified **factory-sharp and unswaged**. Zero history of metallurgical gasket compression, thread galling, or atmospheric oxidation. Ready for immediate UHP commission reaching the 1 × 10-10 Torr floor.

TOP RATED PROTECTION: This listing qualifies for Free 30-Day Domestic Returns. Per eBay Seller Protection policy for Top Rated Plus members, any item returned in a condition different from the original shipment (including but not limited to: **new swage witnesses on the VCR bead**, scratches to the electropolished bore, or evidence of system installation) will result in a 50% deduction from the refund to account for the total loss in technical utility and the transition from NOS to USED status. Technical utility verified prior to shipment.
