1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errors“Laboratory automation equipment” can mean anything from a liquid handler to an integrated sample-preparation and analysis system, so the validation and maintenance details depend on the intended use, instrument, and regulatory setting. There is no single checklist or service interval for every platform. A sound approach is to define what the system must do, qualify it for that use, check its performance over time, maintain it on a justified schedule, and control failures and changes before returning it to service.
1. Define the system’s intended use and scope
Start by writing down the tasks the automation system performs and the results, decisions, or records that depend on it. Define the system boundary broadly enough to include relevant modules, instruments, software, interfaces, data flows, and connected equipment—not just the robot or instrument chassis.
Identify which functions are critical. Depending on the application, these might include sample identification and tracking, liquid transfer, temperature control, timing, mixing, plate movement, instrument communication, calculations, alarms, or generation and retention of results. Consider what could happen if each function failed or produced an incorrect output.
Name the governing quality or regulatory framework before setting acceptance criteria. A clinical laboratory, drug manufacturer, medical-device manufacturer, and research laboratory may have different applicable requirements. FDA Part 11 is not a blanket rule for all automation software: its guidance concerns electronic records created, modified, maintained, archived, retrieved, or transmitted under FDA record requirements.

2. Turn intended use into testable requirements
Write requirements before testing. They should describe the conditions in which the equipment will be used and what acceptable performance looks like. Include only criteria that matter to the actual workflow, but make each critical requirement observable and verifiable.
- Operating range and environmental conditions, such as temperature, humidity, utilities, and workspace constraints.
- Accuracy, precision, capacity, or throughput requirements where relevant to the method.
- Required workflow functions, including alarms, error handling, sample or plate tracking, and recovery from interruptions.
- Interfaces and data handling: what information is exchanged, how errors are detected, and what records must be available and protected.
- Acceptance limits, test conditions, and the evidence that will demonstrate each requirement has been met.
FDA inspection guidance cautions that a process and its parameters must be developed and established before process validation can demonstrate consistent operation. In the manufacturing-validation context it addresses, FDA describes installation qualification this way: “Installation qualification should be conducted for equipment used in a validated process to assure that the equipment has been properly installed, meets the device manufacturer’s specifications and requirements for it, and is capable of operating in the range required for the process being validated.”
3. Qualify installation and operation
Installation qualification (IQ)
Record the installed configuration and verify that the equipment is installed in the required location and conditions, matches relevant manufacturer specifications, and is suitable for the intended process range. Capture equipment identifiers, modules, software or firmware versions where applicable, utilities, and any installation deviations or unresolved issues.
Operational qualification (OQ)
Verify that the equipment and its controls operate as specified across the functions and ranges that matter to the intended use. Use predefined tests and acceptance limits; document the test conditions, results, deviations, and resolution. Decide with the manufacturer or qualified service staff who will perform IQ and OQ, and ensure the person doing the work has appropriate competence and follows the laboratory’s procedures.
CLSI QMS23-Ed2, published June 19, 2019, addresses performance qualification, function checks, calibration verification, and preventive maintenance for general laboratory equipment. Its publication page describes coverage of 20 types of general equipment. CLSI says IQ and OQ are typically completed by a manufacturer technical service engineer; QMS23 focuses on ongoing checks rather than providing IQ/OQ procedures. It is a professional guideline, not a universal legal mandate or a complete checklist for every automated platform.
4. Establish performance qualification and routine checks
Performance qualification (PQ) asks whether the complete system performs acceptably in the laboratory’s actual workflow. Test representative tasks under defined conditions, including the relevant instruments, software, interfaces, consumables, and operators. Use the acceptance criteria established in advance and retain the initial results as a baseline for future comparisons.
Rank #3
- Used Book in Good Condition
Set routine function checks, calibration verification, and preventive maintenance using manufacturer instructions, intended use, equipment criticality, usage, risk, and applicable rules. A maintenance or calibration interval cannot be set responsibly without knowing the equipment and its operating context.
For example, FDA’s balance Q&A says the frequency of external performance checks should reflect use, process criticality, and tolerance. That advice is specific to balances; it does not establish a universal interval for laboratory automation. An automatic calibration routine may not replace an external performance check where the applicable procedure or risk assessment calls for one.

Use equipment-specific procedures and a schedule justified for that equipment and setting. Distinguish among maintenance, function checks, calibration, and calibration verification: they serve related but different purposes, and one activity should not be assumed to replace another. Follow the current manufacturer manual and applicable laboratory procedures.

Record enough information to reconstruct what happened and assess its effect. A practical quality-system record set commonly includes:
- Equipment identity and the relevant module or configuration.
- Date, task performed, person responsible, and service provider where applicable.
- Test or calibration conditions, results, acceptance status, and any deviations.
- Repairs, parts or settings changed, follow-up actions, and evidence supporting return to use.
- Relevant software, firmware, or configuration changes and their review.
Record requirements vary by regulatory setting. For drug CGMP equipment, FDA says equipment should be designed to facilitate its intended use, cleaning, and maintenance, and that cleaning and maintenance should occur at suitable intervals to prevent malfunctions or contamination that could affect product quality. In clinical laboratories, CLIA rules require documented maintenance and function checks as described below.
A paper logbook can be a practical aid if the laboratory’s record-control procedures permit paper records. A generic logbook is not a validated electronic record system, and the laboratory’s requirements determine whether paper documentation is acceptable.

6. Respond to failures before returning equipment to service
If a check fails, a result is out of tolerance, or the equipment behaves unexpectedly, document the issue and stop or restrict affected use as appropriate to the risk. Do not assume that a later successful automatic routine alone resolves the concern.
- Identify the affected equipment, function, workflow, and time period. Assess what has been run since the last acceptable check and whether results, samples, product, or records may be affected.
- Investigate the cause and document the evidence. Consider equipment condition, settings, consumables, software, interfaces, operator actions, and recent service or changes as relevant.
- Correct the problem and perform checks appropriate to the failure and affected requirements.
- Document the results and the decision authorizing return to service. Notify or assess affected stakeholders and results under the laboratory’s procedures.
FDA’s process-validation inspection guidance notes that an out-of-calibration finding after validation calls result validity into question. Its balance Q&A likewise explains that batches between successive external verifications could be affected if an auto-calibrator is later found to have a problem. These examples reinforce the need to assess the interval since the last acceptable verification; the balance-specific guidance should not be treated as a universal rule for every automation platform.

Review changes before relying on prior qualification. This includes moving equipment, major repairs, replacement parts, software or firmware updates, configuration changes, and workflow changes. Determine which requirements and tests are affected, perform proportionate verification or requalification, and document the rationale and results.
FDA says that movement of equipment calls for a new IQ in the process-validation context described in its inspection guidance. That is not a blanket statement about every laboratory system; use the governing requirements and the equipment’s change-control procedures to decide the necessary scope of requalification.

Its software-validation page states that the September 24, 2025 Computer Software Assurance guidance supersedes Section 6 of the older software-validation guidance, which covered automated process equipment and quality-system software. The page also states that the Quality Management System Regulation (QMSR) became effective February 2, 2026 and incorporates ISO 13485:2016 by reference. Medical-device manufacturers should consult the current QMSR and current FDA guidance rather than relying on superseded Section 6 text.
How requirements differ by laboratory setting
| Setting or source | What it addresses | Practical implication |
|---|---|---|
| CLIA clinical laboratories | Federal CLIA rules require manufacturer-defined maintenance and function checks at least as often as specified for unmodified equipment. For equipment that is modified or developed in-house, or when manufacturer protocols are absent, the laboratory establishes protocols supporting accurate and reliable results. | Use the applicable manufacturer protocols for unmodified equipment; establish and document laboratory protocols in the circumstances specified by the rule. The cited federal text comes from the final rule published January 24, 2003; verify current requirements for the laboratory. |
| Drug CGMP | FDA equipment Q&A addresses design for intended use, cleaning and maintenance, cleaning validation, and balance calibration checks. The Q&A includes answers issued on different dates. | Apply the relevant CGMP requirements and attribute dated Q&A advice to its specific subject. Balance-specific external-check advice is not a general automation interval. |
| Medical-device manufacturing | FDA’s software-validation page identifies the QMSR effective date of February 2, 2026, and the September 24, 2025 Computer Software Assurance guidance’s relationship to older guidance. | Use current QMSR requirements and current guidance for software and automated process equipment. |
| Electronic records under FDA rules | Part 11 guidance concerns electronic records maintained under FDA regulatory requirements and recommends risk-based decisions about validation extent. | Determine whether the records and underlying predicate-rule requirements apply; do not assume all automation software is subject to Part 11. |
| General laboratory equipment | CLSI QMS23-Ed2 offers professional recommendations on PQ, function checks, calibration verification, and preventive maintenance. | Use it as a relevant guideline where appropriate, not as a universal legal requirement or a platform-specific validation package. |
Choosing who performs qualification and service
Manufacturer technical service may perform IQ/OQ, while qualified internal staff may be appropriate where laboratory procedures, training, and competence support the work. For routine maintenance or calibration service, assess the provider against the laboratory’s needs rather than treating a service label as proof of suitability.
Quick Recap
- Experience with the specific platform and relevant methods.
- Technical competence and traceable service or calibration records.
- Clarity about parts, settings, software, and configuration changes made.
- Response time and parts access appropriate to the system’s criticality.
