What you should know before buying that instrument.


The challenge of purchasing equipment for a modern laboratory requires original and innovative thinking on several fronts. In today’s fast-changing work environment within the sciences, it is crucial that the manager of a laboratory establishes answers to several important questions, such as:

  • What varieties of equipment are affordable?

With over ten (10) years’ experience which cuts across various laboratory equipment markets, we believe that the important factors to consider when purchasing new instruments are;

1          Instrument related:

  • Confirm application range
  • Sample throughput – Cycle Time to process two or more samples
  • Available Choices (types or choices) and Upgrade Path (future adaptation without repurchasing unit)
  • What standard configuration is best to satisfy your needs?
  • Warranty –

What is the warranty period?

What does it cover?

Does service take place at the factory or on site?

  • Built-In Diagnostics – Does unit include user accessible information for trouble-shooting/maintenance?
  • Operating Environment Requirements and Site Preparation Considerations

2          Data Handling – Instrument Control

  • What is the storage file format and capabilities – can I easily share data or export to Excel, Word and PDF?
  • File Structure –

Ease of retrieving data?

Operation and Set Up?

User interface for new users?

  • Presentation or Publication of Data –

  • Cost of Operation;

What is the projected first year cost of operation?

Parts/Needed Supplies?

4          Manufacturer’s Creditability and Reliability

  • What is the manufacturers’ installed base of users? – How big? Which countries? Who are they? etc.
  • References – Peer review, industry respect
  • Worldwide sales and support – Offices, distribution/distributors, etc.

Selecting and purchasing equipment will likely take some in-depth research due to the variety of instruments available and the detailed nature of their applications. Due diligence regarding the criteria discussed above will help determine what considerations coincide with how best to serve a laboratory. It is crucial to decide wisely when making significant purchases; and just as important not to rush things. The final purchase will ultimately come down to the appropriate piece of lab equipment that meets the preponderance of your wish list needs and is the most beneficial to all involved. The ideal solution for purchasing lab equipment is out there—you just need to do the appropriate homework to find it.
