Bioreactors, chromatography skids and single-use systems proven before GMP campaign start
Commissioning, qualification and validation software for biologics drug substance where bioreactors, chromatography skids, TFF systems and single-use assemblies all have to be qualified before the first cGMP campaign.
A biologics drug substance facility runs upstream cell culture through bioreactors and downstream purification through chromatography, TFF and virus filtration skids, increasingly built around single-use technology that changes assembly-to-assembly. Deskely holds every bioreactor, skid, single-use assembly and clean utility tie-in in one register with IQ, OQ, PQ and GAMP 5 automation qualification gates built in.

The problem
A 2,000 L bioreactor train and a purification suite, and a spreadsheet cannot show which skid still has an open automation qualification exception.
A drug substance facility strings together seed bioreactors, production bioreactors, harvest and clarification skids, chromatography columns, TFF and virus filtration systems, each supplied by a different vendor with its own FAT, and increasingly assembled from single-use components that change lot to lot.
When bioreactor IQ/OQ records, chromatography skid automation qualification and single-use assembly verification sit in separate vendor and engineering files, nobody can confirm before a cGMP campaign start whether the whole train, not just the individual skids, is actually qualified.
Deskely tags every bioreactor, skid, automation recipe and single-use assembly type individually, so campaign readiness is reported from the full train's evidence rather than a skid-by-skid assumption.
Setting up the register
Bioreactors, skids and automation recipes are tagged assets matched to the process flow diagram and control narrative.
Process flow diagrams, P&IDs and control narratives are parsed into a reviewed register, so every bioreactor, chromatography skid and TFF system carries its URS, its automation recipe reference and its vendor FAT data from day one.
IQ and OQ protocols are templated once per skid type under GAMP 5 categorisation, including automation recipe qualification for DeltaV or PLC-based control systems, and instantiated across every bioreactor and skid in the train.
Single-use assembly (SUA) verification — gamma dose confirmation, integrity testing and extractables/leachables documentation — is held as its own record type, distinct from the fixed skid it is installed into, because SUAs change with every lot.
Execution
SIP/CIP cycle verification, automation qualification and PQ are proven skid by skid before the train is released to a cGMP campaign.
Clean-in-place and steam-in-place cycles are verified against each vessel and skid, with thermal mapping, chemical residue testing and cycle repeatability captured against the specific tag rather than a generic utility log.
Automation qualification proves recipe logic, interlocks and alarm management perform as specified across the bioreactor and purification train, with any deviation from the control narrative logged as a finding against the specific automation tag.
Performance qualification runs, including engineering batches, are executed against the qualified train, with in-process data, single-use assembly lot records and deviations tracked to closure before the campaign readiness review.
Campaign readiness and release to GMP manufacturing
The campaign starts from a qualified train, not a collection of individually FAT-passed skids.
Campaign readiness review draws on the qualification status of every bioreactor, skid, automation recipe and SUA type, so the evidence a quality unit needs before the first cGMP batch is an export rather than a cross-functional scramble.
The handover pack for manufacturing and MSAT includes as-built P&IDs, control narratives, qualification summaries and SUA specifications keyed to the train, giving the operating team the same record used to qualify it.
Every signature carries a name, role and timestamp, which is what a quality unit, an FDA pre-approval inspection team and the site's process validation lead expect before a biologics train is declared fit for cGMP production.
Single-use assembly change control
Every new SUA lot is a new component in a qualified train, and a gamma dose or extractables deviation on one bag set cannot be allowed to silently ride into a cGMP batch.
Fixed skids stay the same from campaign to campaign; single-use assemblies do not. A tubing set, bag or filter capsule arrives with its own gamma irradiation certificate, integrity test result and extractables/leachables documentation, and any one of those can differ from the last lot without anyone noticing at the point of use.
On a paper-based programme, SUA lot records are filed by purchase order rather than by the skid position they were installed into, so tracing a downstream deviation back to a specific bag set means asking operators to remember which lot they opened on a given shift.
Deskely records each SUA lot against the exact skid position and batch it was used in, so a gamma dose or integrity exception raised weeks later can be filtered straight to the batches and equipment positions that lot touched, instead of triggering a plant-wide quarantine while the trail is reconstructed.
The upstream and downstream dossier
The evidence chain behind a bioreactor harvest that a QP will actually accept.
Biologics drug substance runs on single-use and stainless trains where cell viability, titre and impurity clearance depend on equipment qualified to hold set-points for days at a time. The dossier links bioreactor, chromatography skid and buffer prep qualification to the clearance and cleaning data that support batch release.
Bioreactor and fermenter IQ, OQ, PQ reports
Temperature, pH, dissolved oxygen and agitation hold set-point across a representative run.
Before first GMP campaign.
Chromatography and TFF skid qualification protocols
Column packing integrity, flow rates and pressure limits are demonstrated for the purification step.
Before process validation batches.
Viral clearance and cleaning validation swab/rinse results
Residual host cell protein, DNA and cleaning agent are below acceptance limits between campaigns.
After cleaning validation runs and periodically thereafter.
Single-use assembly integrity and extractables/leachables reports
Bags, tubing and connectors do not compromise product quality or sterility.
Vendor qualification and lot-specific verification.
Clean-in-place/steam-in-place cycle qualification records
Vessels and lines reach and hold the temperature and chemical exposure needed to clear bioburden.
Before first product contact.
Traceability matrix entries linking URS to DQ to PQ
Every user requirement is demonstrably tested and closed before batch release.

How it runs
From vendor FAT to cGMP campaign start.
Drug substance programmes reward a register that treats the bioreactor and purification train as one qualified system, because a campaign start reviews the whole train, not a single skid.
