Scientists and researchers use a diverse range of instrumentation and laboratory equipment in various scientific fields and industries, from chemistry, biology, and engineering to biotechnology, biopharmaceuticals, and more.
These pieces of equipment are crucial for conducting experiments and research and are used to measure, analyze, and manipulate various samples. In many cases, lab equipment accounts for some of the most significant investments a company will make in its lab and operations. Thus, proper maintenance and management of your investment should be a top priority.
Like all machinery, lab equipment requires regular maintenance to ensure it functions properly and safely. With properly working equipment, reliable data and accurate results can be generated, leading to wasted effort, time, and money.
Practicing proper equipment maintenance procedures, scheduling, and record-keeping is essential to protect your research and equipment investments. Taking care of your instruments ensures proper functionality and increases the span of the equipment’s useful lifecycle.
This article overviews equipment maintenance and how to maintain lab instruments and instrumentation. With diligent equipment care, you can improve quality control, meet industry quality assurance standards and extend the lifespan of your laboratory’s old and new equipment.
Laboratory equipment maintenance refers to the activities performed to ensure your equipment is in good working condition and operating safely. This includes regular equipment calibration, cleaning, lubrication, inspection, testing, and more.
On the other hand, laboratory equipment management refers to the overall management and oversight of your laboratory equipment. This includes maintaining inventory, tracking equipment usage and maintenance schedules, coordinating repairs and replacements, and ensuring compliance with regulations and safety guidelines.
Equipment management also includes ensuring that the equipment is appropriately allocated and utilized, budgeting for equipment purchases and upgrades, and identifying and addressing any equipment-related issues.
Simply put, lab equipment maintenance focuses on the upkeep of the equipment, while lab equipment management focuses on the bigger picture. Both are important for maintaining the integrity and safety of a laboratory, but they have different focuses and responsibilities.
Lab managers often rely on LIMS, or Laboratory Information Management Systems, to manage equipment and ensure operations run smoothly. With LIMS, you can automate the calibrating, maintaining, and monitoring of your equipment. This guarantees that your equipment is running at optimal performance and saves you time and effort by eliminating the need for manual tracking.
A good LIMS can also help you avoid common headaches that come with managing lab equipment. For example, it can automatically schedule regular maintenance checks, track inventory and usage, and provide real-time performance data.
This allows you to focus on your research while the system takes care of the tedious equipment management tasks. Generally speaking, investing in a LIMS can be a smart move for any lab looking to streamline its operations and improve its equipment’s lifespan.
Equipment maintenance is essential for several reasons: it leads to increased uptime, more working hours, and fewer repair costs, ultimately resulting in increased revenue. Improperly maintaining your equipment can result in operational inefficiencies that negatively impact run time, decrease output, and increase costs.
When equipment is well-maintained, it runs more efficiently, regardless of the type of machine. For example, clogged air filters can make the mechanisms of a piece of equipment work harder for the same results. Dirty oil doesn’t lubricate as well as clean oil, worn belts slip, and hoses develop leaks, resulting in increased fluid usage.
In the lab, you might experience one of your centrifuges breaking down. If it is not regularly cleaned and maintained, small particles and debris can build up in the machine over time. This can cause the centrifuge to vibrate excessively during use, potentially leading to mechanical failure. Furthermore, if the seals and gaskets on the centrifuge are not regularly checked and replaced as needed, they can become worn and damaged, allowing fluids to leak out of the machine.
Not only is the centrifuge damaged, but the lab technician using the equipment will also find themselves in a hazardous safety situation. Regular cleaning, inspection, and replacement of broken or damaged seals and gaskets would have prevented the breakdown and potentially led to increased uptime and improved efficiency, which means more hours of operation and better performance during those hours.
More uptime and better efficiency can lead to increased revenue and reduced operating costs, including the cost of running equipment, replacing or repairing parts, or potentially losing productivity to unexpected downtime. These savings can make a significant impact on a business’s bottom line. The difference is even more substantial if a company uses a large amount of equipment.
While some experts may disagree about how many different types of maintenance there are, it’s possible to categorize maintenance into a few common types. These can include:
There may be troubleshooting and maintenance issues your laboratory staff can tackle in-house that include simple preventative maintenance procedures. However, more complicated equipment maintenance procedures and repairs will most likely require the help of a certified technician, whether they work for a third-party or for the equipment’s manufacturer.
Preventive maintenance (PM) is scheduled in advance and aims to prevent equipment failures before they occur. This includes regular inspections, cleaning, and replacement of worn or damaged parts. The goal of preventive maintenance is to extend the life of the equipment and minimize downtime.
It is often planned and scheduled at regular intervals, from weekly to monthly to annually. By performing preventive maintenance, equipment can be kept in good working condition, in turn improving productivity and reducing repair costs.
Predictive maintenance (PdM) uses data and analytics to predict when equipment will fail. This allows for repairs or replacements to be made before a failure occurs.
Predictive maintenance uses tools like sensors and monitoring devices to collect data on equipment performance, which is then analyzed to identify potential issues. PdM can help determine which equipment should receive maintenance before it breaks down, reducing downtime and repair costs.
Corrective maintenance (CM) is used to fix equipment that has already broken down or is not functioning correctly and is typically unplanned. It includes repairs, troubleshooting, disassembly, adjustment, replacement, and realignment.
This type of maintenance is often performed due to equipment failure or when an unexpected breakdown occurs, either due to a lack of a maintenance plan or because a piece of equipment fails before its scheduled inspection or maintenance. It is more expensive than preventive maintenance.
Some labs often rely on CM more than any other type of equipment maintenance. However, solely relying on corrective maintenance instead of a balance of preventive and corrective maintenance has drawbacks.
While corrective maintenance can be effective for quickly fixing equipment that has easily accessible and replaceable parts, it can also lead to unexpected and costly downtime. It is generally recommended that 80% of maintenance efforts focus on preventive measures and 20% focus on corrective actions.
Condition-based maintenance (CBM) is based on the equipment’s condition, using data and monitoring to determine when exactly care is going to be needed, and is similar to predictive maintenance. However, it doesn’t rely on scheduled maintenance. Instead, it uses monitoring and data to identify when equipment is likely to fail and schedule maintenance at that time.
While condition-based and predictive maintenance are often compared due to some similarities, there are some key distinctions between the two. Specifically, the method of measurement that is used.
Predictive maintenance involves using specific formulas and sensor readings (such as temperature, vibration, and noise) to determine when maintenance is needed. Maintenance tasks are then executed based on the analysis of these parameters, making predictive maintenance more of an exact form of care as it anticipates future maintenance requirements.
On the other hand, condition-based maintenance relies solely on real-time sensor readings. Once a reading exceeds an established threshold, maintenance personnel are dispatched to address the issue. This approach means that lab equipment maintenance is only performed when necessary, unlike predictive maintenance, which anticipates future maintenance requirements.
Run-to-failure maintenance (RTF) is the opposite of preventive maintenance and involves waiting for equipment to fail before performing any repairs or replacement. It is a deliberate and considered strategy designed to minimize total maintenance costs.
The run-to-fail method involves having spare parts and personnel readily available to replace failed components and ensure equipment availability. This approach should not be mistaken for reactive maintenance, as a deliberate plan is in place to allow the asset to operate until failure. This strategy is helpful for any equipment that does not pose a safety hazard in the case of failure or breakdown and does not considerably impact production when it breaks down.
RTF is not usually recommended, as it increases the chance of equipment failure and downtime (in fact, it almost bets on failure happening), and it can be more expensive and time-consuming in the long run.
Repairs and maintenance are both essential for equipment to function optimally. However, there are some differences between these two terms.
Repairs are actions taken to restore the proper functionality of the equipment. They are meant to bring something broken back to optimal working conditions. The extent of repairs needed depends on the type of equipment failure that has occurred. Some repairs can be more expensive than others, and the cost will depend on the root cause of the failure.
There are two main types of failure: complete and partial. Complete failure refers to situations where the equipment is entirely unavailable for use and cannot fulfill its intended purpose until it is repaired. A total failure generally leads to unplanned downtime and emergency maintenance, which can be costly.
Partial failure refers to situations where the equipment is still functional to some degree, but it is either unsafe or not working as effectively as it should. It is generally recommended to resolve partial failures as quickly as possible, as doing so will prevent the failure from leading to a complete breakdown at an inconvenient time.
In contrast, maintenance preserves equipment’s functionality, performance, and safety over its lifetime. The primary objective of maintenance is to prevent major or unplanned repairs from occurring by keeping assets in good working condition. Preventative maintenance is performed regularly to ensure that equipment remains in optimal condition, as many equipment failures can be prevented through regular equipment maintenance.
There are often different maintenance procedures for different pieces of equipment. These can be based on the exact type of the instrument and its usage. The procedure can include cleaning, lubrication, inspection, testing, calibration, and more.
The manufacturer will often include or provide recommendations for maintaining the equipment. However, each piece of equipment should have a detailed maintenance schedule in place, and these schedules should be followed and recorded to ensure regular maintenance is performed. This can include a set of instructions or steps that are followed to perform maintenance on a specific piece of equipment.
The different types of maintenance procedure documentation varies and can be as simple as a checklist of tasks to be performed or as complex as a detailed process with troubleshooting steps and diagrams. This can include:
Whatever form of documentation you have access to should outline the tasks that need to be done, the tools and materials required, and any safety precautions that need to be taken. It should be designed to ensure that the maintenance is performed correctly and efficiently, to prolong the equipment’s life, and prevent breakdowns.
Equipment maintenance schedules outline when and how often equipment should be inspected, maintained, and repaired. They ensure equipment is kept in good working condition and minimize potential equipment failures and unexpected downtime. These schedules can vary depending on the type of equipment, how it is used, and the environment in which it operates.
There are several factors to consider when setting up equipment maintenance schedules, including:
Consider these factors when you create a maintenance schedule. It should include the type of maintenance required, the frequency, and the person or team responsible for performing the maintenance. The program should also have a plan for addressing any issues that arise between scheduled maintenance.
Equipment maintenance schedules are not set in stone, however. They should be reviewed periodically and updated as necessary to account for changes in equipment usage, age, or environmental factors.
Keeping detailed records and logs of the maintenance performed on an instrument is an essential step to properly maintaining equipment. You will want to include any repairs or issues that arise, calibration and testing results, and additional information regarding replacement parts or upgrades made to the equipment. Assigning responsibility to a specific individual or team for maintaining equipment maintenance logs can help ensure they are accurate and up-to-date.
These records allow for a clear understanding of your equipment’s maintenance history and identify patterns or issues that may need to be addressed. Well-kept records can be used as a reference in case of equipment failure.
For example, keeping track of calibration and testing results can provide valuable information about the equipment’s performance over time. This information can be used to detect any changes in performance, which indicates a problem that needs to be addressed. Records of repairs and issues that arise can be used to identify common problems and track the repairs’ effectiveness.
Moreover, keeping detailed records of equipment upgrades and replacements can be helpful in understanding the equipment’s maintenance history, providing information on how often parts are replaced, how long they last, and even identifying whether the equipment is reaching the end of its useful life.
Having maintenance records on hand can also be beneficial in case of equipment failure. If properly documented, the record or records will provide valuable information for the technician working on the equipment. Records can also be used to demonstrate that the equipment was properly maintained, which is vital in the case of warranty or insurance claims.
Establishing a system for keeping and updating these records regularly is also essential. A robust LIMS can help you with your record keeping. However, other methods exist for keeping and maintaining maintenance records for all your equipment. These can include:
Laboratory equipment is essential for conducting experiments and research in various fields. But regular maintenance and general care are necessary to keep the equipment functioning correctly and safely.
Regular maintenance can also prevent costly repairs and replacements.
