Cleaning-in-Place (CIP) Systems for Life Sciences and Biopharma

Cleaning-in-Place (CIP) is an automated cleaning method used to clean internal product-contact surfaces of process equipment without dismantling or manual intervention. In life sciences and biopharma facilities, CIP is now standard wherever cleanliness must be demonstrated and documented under GMP and regulatory expectations.

CIP systems reduce cross-contamination risk, remove product residues, and control bioburden and endotoxins, helping to maintain product quality and patient safety. Because cycles are automated and recipe driven, they provide repeatable, validated, and traceable cleaning performance that supports both batch release and inspection readiness.

Core principles of CIP in life sciences

At its core, a CIP process pumps a defined sequence of rinses and cleaning solutions through closed equipment trains such as bioreactors, fermenters, vessels, and transfer lines. This cleaning is carried out in place, removing the need to break sterile boundaries or dismantle complex assemblies between batches.

Most modern CIP designs follow the TACT model, which balances Time, Action (turbulent flow or spray impact), Chemical concentration, and Temperature to achieve the required level of cleanliness. Optimising these parameters shortens cycle times while ensuring all product-contact surfaces reach the target cleaning conditions.

Typical applications in biopharma

CIP is widely applied to bioreactors, fermenters, media and buffer preparation vessels, and product hold tanks in upstream and downstream bioprocessing. It is also used for filtration skids, chromatography systems, filling lines, and associated transfer pipework, hoses, and valves in aseptic and high-care areas.

Multi-product facilities rely on robust CIP programmes during product changeovers, between campaign runs, and after maintenance interventions to prevent cross-contamination between different molecules or batches. In hybrid facilities that combine single-use technologies with stainless steel systems, validated CIP and SIP cycles are key to making re-usable equipment practical and compliant.

Regulatory and GMP context

In regulated life science manufacturing, CIP underpins compliance with GMP by delivering documented, reproducible cleaning results to pre-defined, risk-based residue limits. Automated recording of time, temperature, flow, and conductivity or chemical concentration provides the evidence required for validation, ongoing verification, and inspections.

Regulators expect manufacturers to use science- and risk-based approaches to cleaning validation, including worst-case studies, soiling trials, and periodic requalification of CIP cycles. CIP systems and connected equipment are typically designed to ASME BPE and related sanitary standards to remove deadlegs, ensure full coverage, and support cleanability claims.

Benefits over manual cleaning

Manual cleaning of complex stainless steel bioprocess equipment is labour-intensive, variable, and difficult to validate consistently across shifts and campaigns. CIP replaces this with automated, documented cycles that deliver the same, validated result every time, reducing reliance on operator technique.

Key benefits include reduced downtime through shorter, optimised cleaning cycles, improved safety by limiting operator exposure to chemicals and confined spaces, and lower overall cleaning costs through controlled use and recovery of chemicals and water. By minimising residue and bioburden risk between batches, CIP directly supports product quality and reduces the likelihood of deviations or batch rejections.

Suncombe’s experience with CIP

Suncombe is a specialist in cleaning and critical process systems and has supplied CIP solutions to the biopharma sector, laboratories, and research institutes for decades. Its portfolio includes PureCIP and MobileCIP systems that can be integrated with PureVessel bioprocess vessels to provide pre-validated CIP and SIP cycles.[9][11][^8]

These pre-validated combinations allow each vessel to be recognised by the automation system, which then selects the appropriate cleaning and sterilisation recipe and generates an electronic or paper batch report compliant with 21 CFR Part 11. The approach supports hybrid facilities where reusable stainless steel equipment must coexist with single-use technologies while maintaining sterility and avoiding cross-contamination.

Mobile CIP & Static CIP System – The Differences

Clean In Place systems may be fixed in one location or mobile so as to facilitate several points of use. They may be designed as “total loss” systems, where the washing media is used once only before passing to drain or “recovery” systems, which recycle some of the washing media for part of the cycle.

Mobile CIP & WIP System

A mobile CIP system is a total loss Clean-in-Place system, where the entire system is equipped with wheels to move to its point of use. Its special design and development meet the ASME BPE standards essential to the BioPharma industry. Mobile CIP & Wash-in-Place (WIP) can be operated manually or automatically to clean processing equipment such as tanks, vessels, vats, fermenters, mixers, processors, pipework, valves, isolators, mills, coaters, filters, pumps, dryers, and fillers. Our Mobile CIP product range features multiple variants, namely CIP Trolley, CIP Washer, Mobile CIP®, and MobileCIPOneTM offering unique benefits to each client.

Static CIP System

Effective cleaning of equipment and piping systems is easy when using a Static CIP system. Our Static CIP systems services in the UK are designed to clean and sanitise equipment and piping in place without the need for time-consuming disassembly. Our Static CIP system design facilitates the cleaning of hard-to-reach areas within the processing equipment. These systems are designed to minimise the use of water and chemicals while keeping precise control over the cleaning parameters including the cleaning solution concentration and contact time. Optimise your operational efficiency by reducing downtime through our automatic, efficient, and precise Static CIP systems.

CIP in hybrid and multi-use facilities

In hybrid bioprocess facilities, stainless steel vessels and equipment remain attractive for their robustness, heat transfer, and lifecycle cost, but require reliable CIP and SIP strategies to manage cleaning complexity. Pre-validated CIP solutions allow operators to gain the benefits of re-usable systems without compromising on compliance or sterility assurance.

By combining modular, certified vessels with application-specific CIP equipment, manufacturers can standardise cleaning across multiple assets, simplify validation, and generate consistent electronic batch records for every cleaning cycle. This is particularly valuable in multi-product sites, where rapid changeovers and predictable, validated cleaning are essential to meeting production schedules and regulatory expectations.

Cleaning-in-Place systems have become a cornerstone of controlled manufacturing in life sciences and biopharma, enabling automated, validated cleaning of complex stainless steel equipment without dismantling. By tightly controlling and documenting each step of the cleaning recipe, CIP reduces cross-contamination risk, supports product quality, and underpins GMP compliance.

Vendors with deep experience in both process and cleaning system design, such as Suncombe, can help life science organisations implement CIP solutions that integrate with hybrid facilities, simplify validation, and provide confidence that every batch starts from a proven, clean state.

How a CIP cycle works

A typical CIP cycle for a bioreactor or vessel starts with a pre-rinse using purified water to remove bulk residues and wet the surfaces. This is followed by an alkaline wash, often based on sodium hydroxide, circulated or sprayed at elevated temperature to dissolve and remove product, media, and biofilm soils.

Depending on product and residue type, the sequence may also include an acid wash to remove mineral or inorganic deposits, intermediate rinses to prevent carryover, and a final rinse with purified or WFI water to meet conductivity or TOC endpoints. Air blows or drain and dry steps can then prepare equipment for sterilisation-in-place (SIP) or for the next production batch.

Design considerations for effective CIP

Effective CIP starts at the equipment design stage, where vessels, piping, valves, and instruments must be configured for cleanability as well as process performance. Typical requirements include correctly placed spray devices, self-draining pipework, minimal deadlegs, and hygienic, crevice-free connections.

CIP systems themselves must be sized to deliver sufficient flow, pressure, and temperature to all points in the circuit while avoiding cavitation or stagnation. Programmable logic controllers (PLCs) are used to automate the sequence, interlocks, and data capture, and to provide flexible, recipe-based cleaning for different products or equipment trains.
