Lab Manager, a leading publication in the field of laboratory management, recently highlighted the challenges faced by laboratory managers–the issue of whether to repair or replace ageing instruments. In this article, the journal offers insights into identifying the red flags that indicate the need for equipment replacement.
Deciding when to repair versus replace an instrument in the lab can be a complex decision. However, the article stresses the importance of recognising signs that indicate it may be time to retire ageing equipment. It has distilled these insights into five key red flags that lab managers should consider.
The first one, lab safety, is the top priority for any responsible lab manager, states the article. It explains that a single malfunction may not necessarily require immediate replacement. However, repeated malfunctions or issues of increasing severity are clear indications that the instrument’s reliability is compromised. It is crucial to keep comprehensive service and repair logs and periodically review them for trends. Lab managers need to stay alert. If equipment has frequent or serious malfunctions, it should be taken out of use quickly. This is important to keep the personnel safe and maintain the integrity of experiments.
Inaccurate results from lab equipment can have far-reaching consequences. Lab Manager emphasises that compromised data integrity affects research outcomes and can impact patient diagnoses and treatment plans. It is critical to identify instruments that consistently produce inaccurate results and determine whether they need to be replaced. Not doing so can significantly impede progress, waste resources, and compromise the reputation of the laboratory, the article asserts.
Finding replacement parts for ageing equipment can be a daunting task. Lab Manager warns that relying on third-party sources for unavailable manufacturer parts can result in extended downtime and reduced productivity. Investing in a new instrument may be a better choice than searching the internet for parts. Even though it may cost more initially, it can be more cost-effective in the long run.
As technology advances, lab equipment is becoming increasingly energy-efficient. Lab Manager highlights advancements such as carbon fibre centrifuge rotors and hydrocarbon refrigerants in ULT freezers, which contribute to faster run times and lower energy consumption. Buying a new and more efficient model can save costs and make the lab more eco-friendly, taking into account the equipment’s age and frequency of use.
The article also points out that any repair should be undertaken by reputed companies–such as Cambridge Glassblowing for scientific borosilicate glassware–to ensure that the instrument comes back as good as new.
While regular maintenance is crucial, there comes a point where the cost of repairs outweighs the benefits. Lab Manager emphasises that if the frequency or magnitude of repairs approaches or surpasses the cost of purchasing a new unit, lab managers should allocate resources toward a replacement. This ensures the lab operates with reliable, up-to-date equipment, optimising productivity and minimising long-term costs, it concludes.
