Equipment Management Overview

Equipment management is a crucial aspect of a quality management system in laboratories.
It ensures reliable, accurate, and timely testing, contributing to overall laboratory performance.
A robust equipment management program reduces test result variations, enhances technologist confidence, lowers repair costs, extends instrument lifespan, minimizes service disruptions, promotes worker safety, and increases customer satisfaction.
The laboratory director is responsible for overseeing the equipment management program, ensuring appropriate training for personnel, and proper instrument operation and maintenance procedures.
A designated individual with expertise in equipment maintenance and troubleshooting can effectively manage the program.

Selecting and Acquiring Equipment

When selecting equipment, consider its suitability for the laboratory's services, performance characteristics (accuracy and reproducibility), facility space requirements, budget constraints, reagent availability, ease of operation, language compatibility, local retailer support, warranty coverage, and safety considerations.
Laboratory managers should provide input on equipment selection even when purchasing decisions are made by central bodies or donors.
Consider purchasing, renting, or leasing based on factors like repair costs and potential savings for multiple equipment needs.
Before purchasing, ensure the manufacturer provides wiring diagrams, software information, parts lists, an operator's manual, installation and staff training, a trial period, and maintenance contract options.
Verify that the laboratory can provide necessary physical requirements like electricity, water, and adequate space for equipment placement (considering door and elevator access).

Getting Equipment Ready for Service

After installation, assign responsibility for maintenance and operation, establish a system for parts and supplies tracking, implement a written calibration and performance verification plan, establish a scheduled maintenance program (daily, weekly, monthly), and provide operator training only to authorized personnel.
Calibrate instruments during initial service and determine recalibration frequency based on stability and manufacturer recommendations.
Utilize manufacturer-supplied or purchased calibrators.
Before testing patient specimens, evaluate new equipment for accuracy and precision.
Validate new equipment and techniques by comparing results with previous methods to ensure expected outcomes.
Perform periodic function checks (temperature monitoring, wavelength calibration) to verify equipment performance.

Implementing an Equipment Maintenance Program

Preventive maintenance includes regular cleaning, adjustments, and part replacements based on scheduled intervals (daily, weekly, monthly, yearly).
Following manufacturer recommendations maximizes equipment efficiency and lifespan, preventing inaccurate results, delays, productivity loss, and high repair costs.
Create written policies and procedures for equipment maintenance, including routine maintenance plans for each instrument specifying frequencies.
Develop record-keeping formats, logs, and forms for maintaining records.
Train staff on equipment use and maintenance, emphasizing their specific responsibilities.
Maintain an inventory log of all equipment, including instrument type, make, model, serial number, purchase date, vendor information, documentation availability, warranty expiration, and a unique inventory number.
Conduct inventory checks regularly to assess equipment condition (functional, partially functional, non-functional) and plan repairs or retirement.
Keep an inventory record of frequently used spare parts, including name, number, average usage, minimum stock, cost, and date of storage and usage.

Troubleshooting, Service, Repair, and Retiring Equipment

Operators should be trained to troubleshoot equipment problems to minimize disruption in testing operations.
Begin troubleshooting by repeating preventive maintenance procedures, then use manufacturer-provided flowcharts to identify the source of the issue.
Consider factors like sample quality, reagent integrity, water or electrical supply, and equipment operation when troubleshooting.
If in-house troubleshooting fails, arrange for backup instruments, request manufacturer replacement, or send samples to a nearby laboratory.
Never use faulty equipment.
Seek assistance from the manufacturer or technical experts.
Establish a procedure for scheduling manufacturer-performed service.
Ensure repairs are handled by the manufacturer when required by warranty terms.
Develop policies and procedures for retiring outdated or non-functional equipment, including disposal procedures.
Salvage usable parts from retired equipment and prioritize safe disposal of any biohazards.

Equipment Maintenance Documentation

Well-defined policies and procedures for equipment maintenance are essential components of a quality system.
Maintain comprehensive documentation including inventory logs, manufacturer-provided information, and detailed records of all maintenance and repair activities.
Each major equipment piece should have its own maintenance document, while smaller, commonly used equipment can be managed collectively.
Dedicated logbooks for each instrument should document preventive maintenance activities, function checks, calibrations, manufacturer-performed maintenance, and any equipment problems encountered, including corrective actions taken, resolution details, and any resulting changes to procedures.
Utilize charts, logs, checklists, graphs, and service reports for record-keeping purposes.
Ensure logbooks are readily available for review throughout equipment lifespan.

Summary

A well-organized equipment management program is crucial for all laboratories.
It encompasses equipment selection, preventive maintenance, and troubleshooting procedures.
Comprehensive documentation, including inventory logs, manufacturer guidelines, and maintenance records, is essential.
A robust equipment management program ensures reliable performance and high confidence in test result accuracy.

Centrifuge

Centrifuges are instruments that spin samples at high speeds, forcing the heavier particles to the bottom of the container.
The rotor holds the tubes and rotates during operation.
Centrifuges are used to separate cellular components of blood from serum or plasma and to centrifuge urine to obtain urine sediment.
Clinical centrifuges are used for urinalysis or serum separation.
Clinical centrifuges can be large floor models or small benchtop models.
Clinical centrifuges usually have a speed capacity of 0 to 3000 rpm and hold tubes ranging in size from 5 to 50 mL.
It is important to balance tubes in a centrifuge rotor for safety and proper operation.
Tubes should be evenly filled and matched in weight when placed opposite each other in the rotor.
Capped tubes should remain capped during centrifugation to prevent contamination and dehydration.
Do not exceed the manufacturer’s recommended maximum speed.
If the centrifuge begins to shake or wobble, it likely means it is not balanced properly and should be stopped immediately.

Pipette

Micropipettes come in different sizes and are used for precise liquid transfers.
The adjustable wheel or plunger sets the desired volume.
It is crucial to stay within the volume range of the respective pipette to avoid contamination or inaccurate measurements.
Proper pipetting technique ensures accurate volume transfer.
Before drawing up liquid, a sterile tip is added to the pipette.
The plunger is pressed to the first stop and the pipette tip is dipped 3-4 mm into the liquid.
The plunger is released slowly and in a controlled manner.
To dispense liquid, the pipette tip is held against the side of the tube at a 30-40 degree angle or dipped beneath the surface of the liquid already in the tube.
The plunger is pressed to the second stop to ensure all the liquid is expelled.
The tip is discarded into the trash after each pipetting event using the ejector.

Serial Dilution

Serial dilution is used to create solutions with progressively lower concentrations.
The dilution factor is determined by the desired final concentration and initial concentration.
Multiple dilutions can be performed in a series of tubes for accurate results.
A 10X dilution means 1 part of the solution and 9 parts of the diluent.
For a 15X dilution, it is 1 part of the solution and 14 parts of the diluent.
Serial dilution requires more preparation but provides accurate dilutions with precise technique.

Sterilization

Sterilization refers to the complete removal of all microorganisms.
Autoclaving is used to sterilize media and containers, utilizing high-pressure saturated steam at 121°C for 15 to 20 minutes.
Autoclave tape is used to indicate whether a bottle of medium has been autoclaved properly, turning black when subject to high-temperature steam.
Lab equipment can be sterilized through autoclaving, heating on a flame, or using disinfectants like ethanol.
