Bioprocessing equipment maintenance 101: Your guide to smarter equipment ownership

Most bioprocessing teams have experienced it – that heart-sinking moment when equipment fails and everything comes to a standstill.

An entire batch may be compromised, pushing production schedules and wasting significant time, materials, and effort. Repairs can also be expensive and spare parts can take weeks to arrive–especially if they need to be custom made–racking up huge financial losses. In a recent analysis, pharmaceutical manufacturing downtime cost £1–£5 million per hour, with single major incidents resulting in £5–£10 million in losses1.

And it’s not just equipment failure that you need to watch out for. Equipment errors can go unnoticed, and as a result, processes can drift from their validated state, risking product quality and safety. Even small process deviations can lead to large issues.

These challenges are only being exacerbated by growing cost and time pressures. To keep production moving, it can be tempting to adopt a “run-to-failure” approach, addressing repairs only when problems can no longer be ignored. While this may save time or budget in the short term, when incidents do happen, disruption, higher repair costs, and longer periods of equipment downtime can be expected.

This is why equipment ownership and maintenance need to be proactive, rather than reactive. That means using the correct operational protocols, implementing best practices such as cleaning after use, looking beyond ad-hoc fixes and building an equipment maintenance strategy that prevents costly issues before they occur, preserving sustainable long-term production.

To help you develop an effective maintenance strategy, this article provides an overview of the key components involved, describing how these enable reliable, resilient bioprocessing. You can also find practical tips to help put your strategy into motion, including how working with a reliable service partner can make this process easier and more efficient.

Developing a smart, multi-faceted maintenance strategy

Effective maintenance requires a lifecycle approach to ensure your equipment performs well from the moment it’s installed until the end of its life (Fig 1). The following sections outline the key elements of this approach, from qualification through to staff training, preventive maintenance, spare parts, remote monitoring, and service plans.

1. Qualification (IQ/OQ)

Initial qualification and subsequent requalification throughout the equipment lifecycle provides documented evidence that systems are installed correctly, operate as intended to manufacturer specifications, and perform reliably (Fig 2). Without maintaining proper qualification, you risk failing to comply with regulatory standards and GMP requirements, as well as quality issues, product recalls, production delays, and serious safety issues.

Qualification follows several key phases:

• Installation qualification (IQ) – Confirms correct setup.
• Operational qualification (OQ) – Verifies functionality under expected and stress conditions.
• Performance qualification (PQ) – Demonstrates consistent performance in routine use.
• Requalification (RQ) – Confirms equipment remains compliant after changes, repairs, or relocation.

Top tip: Follow a lifecycle and risk-based approach

Adopt a structured lifecycle-based approach for qualification, covering IQ, OQ, PQ, and requalification after upgrades, repairs, or relocation. This approach aligns with quality by design (QbD) and International Council for Harmonization (ICH) Q8–Q10 principles, which focus on building quality into processes from the start and maintaining it over time. You should also use failure modes and effects analysis (FMEA) to identify where equipment failure would have the greatest impact on product quality, patient safety, or compliance, and focus qualification efforts accordingly.

2. Training

Training should be a core element of your maintenance strategy, as it gives in-house teams the knowledge and confidence to use equipment the right way from the very start. When operators understand how a system is supposed to work, they’re less likely to make mistakes that could affect performance or damage the equipment, helping extend its lifespan and reduce the risk of breakdowns.

It also means staff know what to look for when it comes to faults. They can spot early signs of wear or potential issues before they turn into bigger, more expensive problems. This helps keep everything running smoothly and supports consistent product quality. Training also builds capability across your organization. When teams can operate and take care of equipment themselves, there’s less need to rely on external engineers, and issues can be resolved faster.

Top tip: Prioritize training, and make sure it doesn’t stop!

Consider different formats of training that blend practical and theory-based exercises and training locations, for example on-site or at the original equipment manufacturer (OEM) training facility. This provides different insights, makes ongoing training more of a varied experience and builds strong in-house capability over time.

3. Preventive maintenance

As industry pressures increase, reducing downtime is more important than ever. Relying on reactive maintenance just isn’t enough. Companies need to shift toward a proactive, preventive maintenance approach that helps avoid problems before they occur.

Preventive maintenance means inspecting equipment regularly, replacing parts on a planned schedule, and carrying out servicing based on expected use and performance. This keeps systems operating within specification, reduces the risk of sudden failures, supports compliance requirements, and helps extend equipment lifespan. It also makes costs and downtime easier to plan for.

However, preventive maintenance only works when it is well organized and consistently carried out. Without this structure, maintenance can slip, small issues may go unnoticed, and equipment can drift out of specification. As systems become more automated and interconnected, maintaining this consistency becomes even more important.

Top tip: Build a proactive, digitally supported maintenance model

Create a clear maintenance calendar that sets out daily, weekly, monthly, and annual tasks, and assign responsibilities so nothing is missed. Make sure your schedule follows OEM maintain validated performance and support compliance.

4. Spare parts planning

Having the right spare parts on hand can make all the difference. Even a small missing component can halt production and delay schedules. With many critical parts having long lead times or custom manufacturing requirements, relying on last-minute sourcing is risky. Yet on the other hand, stocking too many spares ties up budget on items that may sit unused.

A strategic approach is needed to balance risk without unnecessary spending. This means understanding which components are truly critical to uptime, ensuring they are always available, and avoiding unnecessary stockpiling of lower-priority items. By holding the right parts, facilities can minimize downtime, manage costs more effectively, and improve overall operational resilience.

Top tip: Optimize your spare parts inventory

Use a centralized inventory system to gain full visibility of stock levels, locations, and documentation. Apply data analytics and ABC/XYZ analysis to identify which parts are critical and need to be kept on hand, and which lower-priority items can be ordered as needed. Finally, conduct regular audits and reviews to remove obsolete stock and keep records accurate. This ensures critical parts are always available while avoiding unnecessary spending on items that are rarely used.

5. Remote support

With the industry facing several challenges, keeping equipment running reliably has never been more important. Tighter budgets make downtime more costly, continuous production leaves less room for disruption, sustainability goals push teams to reduce environmental impact, and digitalization demands strong data security and traceability. In this fast-paced environment, remote equipment monitoring is becoming a valuable tool for reducing downtime and maintaining compliant operations.

Remote monitoring provides real-time, data-driven visibility into how equipment is performing. Continuous health checks help teams spot early signs of wear, drift, or component fatigue, so preventive maintenance and spare parts planning can happen at the right time. This minimizes unplanned downtime and keeps production running smoothly.

When an issue does occur, remote troubleshooting allows engineers to diagnose problems and guide on-site teams through fixes, often restoring uptime within hours, without waiting for a site visit. This lowers repair costs, speeds recovery, reduces travel-related emissions, and avoids unnecessary disruption.

Remote support platforms are also designed with data integrity and security in mind. Encrypted data transfer, controlled user access, and automated audit trails help maintain compliance while still providing real-time operational insight.

Top tip: Integrate remote monitoring and troubleshooting into routine operations

Connect equipment to your remote monitoring platform and set clear alerts so you know as soon as something starts to drift.

Keep everything in one place with a centralized dashboard, so your team can quickly check equipment status and service history. When an issue comes up, use remote support tools first to diagnose the problem and try to fix it remotely, only requesting an on-site visit if needed. Over time, use the performance trends you collect to plan preventive maintenance and make sure the right spare parts are available.

6. Plans for maintenance and repairs

Service plans offer a more reliable and cost-effective approach to equipment support, compared to ad-hoc requests. Instead of reacting to problems one at a time, service plans provide ongoing access to vendor expertise, scheduled preventative care, and priority response when an issue does arise.

One of the biggest benefits of service plans is that they make costs easier to manage. When support is built in upfront, you avoid surprise repair bills or last-minute call-out fees, and maintenance costs are more predictable over time. It also saves the administrative burden of raising purchase orders for each repair or health check and provides peace of mind in terms of response and repair timelines.

Because no two facilities operate the same way, with different usage levels, regulatory pressures, production schedules, and in-house expertise, having the flexibility to tailor service plans is essential.

Top tip: Customize service plans to your operational needs

Not every system needs the same level of coverage. Start by assessing each instrument’s criticality, usage intensity, regulatory requirements, and the impact downtime would have. High-criticality or high-throughput equipment may benefit from faster response times, scheduled preventive maintenance, remote monitoring, and fast access to certified engineers. Lower-risk systems may only require basic support. Aligning service plans to the real demands of your workflow ensures you’re investing where it matters most.
