Sourced against the requirement PDF (27 machine positions, 3 lines). Manufacturer shortlist verified live — every entry has a live website and a product portfolio matching the listed positions. Verification = existence + portfolio match only; not an in-house-capability, credit, or GMP check. Gaps (esp. 0.22 µm sterile filtration) flagged honestly.
Coverage matrix — which of the 27 positions each supplier covers
Critical sourcing gaps (verify separately)
N4 — 0.22 µm Sterile Membrane Filtration System: NONE of the 10 verified filling-line makers are confirmed to supply a pharma-grade sterile filtration skid (housing, membrane, integrity test, SIP/CIP, SS316L, documentation). Source from a dedicated filtration specialist.
S3 — Sanitary Transfer Pump: not confirmed in any of the 10 portfolios; usually a pump specialist (sanitary centrifugal / positive-displacement).
S4 — Cartridge Filtration Unit: not confirmed; related to N4 sourcing.
S1 / N1 — SS Jacketed Manufacturing Vessel w/ Agitator: Lianhe (SUP-0009) offers jacketed SUS316L tanks but an agitated jacketed manufacturing vessel is not explicitly confirmed — verify.
In-house vs outsourced: require every shortlisted supplier to state which machines are made in-house vs sourced. Several integrate lines that may blend own + third-party equipment.
