How to Evaluate Extraction Equipment for EU GMP Readiness
Evaluate EU GMP readiness by inspecting four things: product-contact surfaces and cleanability, the documentation package offered with the system, the qualification path from IQ through PQ, and how the control system records and protects batch data. Ask for evidence of each in writing before ordering, not after delivery.
A fifth check — the supply chain behind the equipment — decides whether you stay in a validated state once you are running. Below is the sequence we would use. For the requirements these checks are testing against, see the EU GMP equipment guide. If the extraction method itself is still open, hydrocarbon vs ethanol vs CO2 for EU GMP facilities sets out how the compliance burden differs before any specific system is on the table.
Step 1: Walk the product-contact path
Physically trace where product travels, from material loading to collection. At each stage ask three questions: what is this surface made of, how does it drain, and how is it cleaned and inspected?
Look for sanitary connections rather than threads in product-contact areas, drainable low points, and an absence of dead legs. Then ask how cleaning effectiveness will be demonstrated — a procedure with defined acceptance criteria, not an assurance that the system "cleans well." Collection vessels, sight glasses and sample points deserve particular attention, since they are easy to overlook and awkward to clean.
Run it across the whole train rather than the extractor alone. A hydrocarbon platform such as the 15.HX puts material columns, a collection vessel and a solvent tank in the product path; a 50.FF falling film evaporator and a 12.CF cartridge filtration system extend that path downstream. Every added vessel is another set of surfaces someone has to clean, inspect and prove clean.
This is the check that rewards the most preparation, because it is the one you cannot fix later. Our guide to cleanability and sanitary design covers what to look for joint by joint.
Step 2: Ask for the documentation list in writing
Request the actual document list for the configuration you are quoting, not a general statement about GMP support. You are looking for material certificates on product-contact stainless, weld documentation where applicable, component and instrumentation records, and the qualification protocols.
Documentation packages to support IQ/OQ/PQ and facility turnover are available, and scope varies by model and configuration — which is exactly why the list should be confirmed with engineering before ordering rather than assumed. A catalogue model such as the 20.EX has a published specification you can quote against; a platform configured per order, such as the 75.HX, does not, so its document list has to be agreed in writing rather than inferred from a web page. If a supplier cannot produce the list before purchase, treat that as the answer.
Step 3: Map the qualification path
Work through how the system will actually be qualified:
- IQ — is the installation specification clear enough to verify against? Are utilities, components and drawings defined?
- OQ — does the equipment have testable operating ranges, with alarms and interlocks that can be challenged?
- PQ — can the system demonstrate consistent performance on your material, at your intended output?
The question underneath all three is whether the equipment has defined, measurable specifications. Anything that cannot be measured against acceptance criteria cannot be qualified, and vague performance claims become your problem at PQ.
Keep design intent separate from qualification evidence while you work through it. The 20.EX is documented as designed to support EU-GMP facility compliance, which tells you what the machine was built for; it does not qualify anything on your behalf. The protocols, the runs and the acceptance criteria remain yours to write and execute.
Step 4: Test the control system's record-keeping
Under Annex 11, the control system is in scope. Ask to see it, not just read about it. Check for individual user accounts and access control, an audit trail that captures changes to critical process parameters, reliable timestamping, and batch data that exports into your records rather than being transcribed by hand.
Manual transcription is worth flagging specifically: it is both a recurring labour cost and a data-integrity weakness. Ask what each control system captures and retains: our 80.TF documents a networkable touchscreen HMI with real-time data monitoring and remote support, but real-time monitoring is not the same as an attributable, retained batch record. For that platform, the 30.TF or anything else you are comparing, confirm what is logged, where it is stored and who can alter it.
Step 5: Check the support and supply chain
A validated state is something you maintain, not something you achieve once. Under GMP, substituting a product-contact component is a documented change that can put cleaning validation in question.
So evaluate the supplier as well as the machine: lead times on critical spares, consistency of machine parts and filter media, field service availability, and whether engineering support is reachable when something is unclear at two in the afternoon on a production day.
A practical evaluation checklist
Before you shortlist, confirm you can answer yes to each:
- The product-contact path is fully traceable, drainable and cleanable to a defined procedure
- The document list for your exact configuration is confirmed in writing
- IQ, OQ and PQ each have testable specifications and acceptance criteria
- The control system has access control, an audit trail and exportable batch data
- Critical spares and consumables have a known, consistent source
- The supplier describes equipment as supporting site certification, not as being certified itself
That last point is a useful integrity check on any vendor conversation. Equipment is never EU GMP certified; sites are. If the distinction is unfamiliar, GMP vs EU GMP for extraction facilities sets out what each term actually commits a supplier to.
FAQ
What is the single most important thing to check?
The product-contact path. Documentation gaps can be closed after the fact and qualification protocols can be written, but surfaces, welds, drainability and dead legs are built into the machine. If cleanability is wrong at delivery, the remedy is usually replacement rather than remediation.
Can a supplier tell me their equipment is EU GMP certified?
They should not, because no such certificate exists for equipment. Certification is issued to sites following inspection by a competent authority. A credible supplier describes equipment as designed and documented to support your site's certification, and can show you the documents that back the claim.
What documentation should I ask for before ordering?
Ask for the document list specific to your configuration rather than a general capability statement: material certificates on product-contact stainless, weld documentation where applicable, component and instrumentation records, and the qualification protocols. Scope varies by model and configuration, so confirm it with engineering in writing before the order rather than after.
When should I start the qualification conversation?
Before purchase. Annex 15 expects qualification to be planned rather than reconstructed, and the specifications you will qualify against have to exist in the quote. Starting at delivery means writing acceptance criteria around whatever arrived, which is both slower and weaker.
How much does the control system really matter?
More than most buyers expect at the quoting stage. Under Annex 11 it is in scope, and manual transcription of batch data is both a recurring labour cost and a data-integrity finding waiting to happen. Confirm what is captured, how long it is retained and who can alter it — real-time monitoring on a screen is not the same as a retained, attributable record.
Talk to engineering before you specify
Most of these checks are quick when asked early and costly when asked late.
